+## Thank you for sending in a pull request, here's some tips to get started!
+
+(Please delete all these tips and replace with your text)
+
+- Before starting on some new big chunk of code, it it is optional but highly recommended to open an issue first
+  to say "hey, I think this idea X should be implemented and I'm starting work on it. My general plan is Y, any feedback
+  is appreciated." This will allow other devs to potentially save you time by not accidentially duplicating work etc...
+- Please do not check in files that don't have real changes
+- Please do not reformat lines that you didn't have to change the code on
+- We recommend using the [Visual Studio Code](https://platformio.org/install/ide?install=vscode) editor and the 'clang-format' extension,
+  because automatically follows our indentation rules and it's auto reformatting will not cause spurious changes to lines.
+- If your PR fixes a bug, mention "fixes #bugnum" somewhere in your pull request description.
+- If your other co-developers have comments on your PR please tweak as needed.

 # Meshtastic-device
+[![Open in Visual Studio Code](https://open.vscode.dev/badges/open-in-vscode.svg)](https://open.vscode.dev/meshtastic/Meshtastic-device)
+## This repository contains the device firmware used in the [Meshtastic](https://meshtastic.org) project.
 
-This is the device side code for the [meshtastic.org](https://www.meshtastic.org) project.
-
-![Continuous Integration](https://github.com/meshtastic/Meshtastic-esp32/workflows/Continuous%20Integration/badge.svg)
-
-Meshtastic™ is a project that lets you use
-inexpensive GPS mesh radios as an extensible, super long battery life mesh GPS communicator. These radios are great for hiking, skiing, paragliding -
-essentially any hobby where you don't have reliable internet access. Each member of your private mesh can always see the location and distance of all other
-members and any text messages sent to your group chat.
-
-The radios automatically create a mesh to forward packets as needed, so everyone in the group can receive messages from even the furthest member. The radios
-will optionally work with your phone, but no phone is required.
-
-Typical time between recharging the radios should be about eight days.
-
-This project is is currently in beta-testing - if you have questions please [join our discussion forum](https://meshtastic.discourse.group/).
-
-This software is 100% open source and developed by a group of hobbyist experimenters. No warranty is provided, if you'd like to improve it - we'd love your help. Please post in the chat.
-
-## Supported hardware
-
-We currently support three models of radios.

-Getting a version that includes a screen is optional, but highly recommended.
-
-## Firmware Installation
-
-Prebuilt binaries for the supported radios are available in our [releases](https://github.com/meshtastic/Meshtastic-esp32/releases). Your initial installation has to happen over USB from your Mac, Windows or Linux PC. Once our software is installed, all future software updates happen over bluetooth from your phone.
-
-Please post comments on our [group chat](https://meshtastic.discourse.group/) if you have problems or successes.
-
-### Installing from a GUI - Windows and Mac
-
-1. Download and unzip the latest Meshtastic firmware [release](https://github.com/meshtastic/Meshtastic-esp32/releases).
-2. Download [ESPHome Flasher](https://github.com/esphome/esphome-flasher/releases) (either x86-32bit Windows or x64-64 bit Windows).
-3. Connect your radio to your USB port and open ESPHome Flasher.
-4. If your board is not showing under Serial Port then you likely need to install the drivers for the CP210X serial chip. In Windows you can check by searching “Device Manager” and ensuring the device is shown under “Ports”.
-5. If there is an error, download the drivers [here](https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers), then unzip and run the Installer application.
-6. In ESPHome Flasher, refresh the serial ports and select your board.
-7. Browse to the previously downloaded firmware and select the correct firmware based on the board type, country and frequency.
-8. Select Flash ESP.
-9. Once complete, “Done! Flashing is complete!” will be shown.
-10. Debug messages sent from the Meshtastic device can be viewed with a terminal program such as [PuTTY](https://www.putty.org/) (Windows only). Within PuTTY, click “Serial”, enter the “Serial line” com port (can be found at step 4), enter “Speed” as 921600, then click “Open”.
-
-### Installing from a commandline
-
-These instructions currently require a few commmand lines, but it should be pretty straightforward.
-
-1. Install "pip". Pip is the python package manager we use to get the esptool installer app. Instructions [here](https://www.makeuseof.com/tag/install-pip-for-python/). If you are using OS-X, see these [special instructions](docs/software/install-OSX.md).
-2. Run "pip install --upgrade esptool" to get esptool installed on your machine.
-3. Connect your radio to your USB port.
-4. Confirm that your device is talking to your PC by running "esptool.py chip_id". The Heltec build also works on the TTGO LORA32 radio. You should see something like:
-
-```
-mydir$ esptool.py chip_id
-esptool.py v2.6
-Found 2 serial ports
-Serial port /dev/ttyUSB0
-Connecting....
-Detecting chip type... ESP32

-Warning: ESP32 has no Chip ID. Reading MAC instead.
-MAC: 24:6f:28:b5:36:71
-Hard resetting via RTS pin...
-```
-
-5. cd into the directory where the release zip file was expanded.
-6. Install the correct firmware for your board with `device-install.sh firmware-_board_-_country_.bin`.
-   - Example: `./device-install.sh firmware-HELTEC-US-0.0.3.bin`.
-7. To update run `device-update.sh firmware-_board_-_country_.bin`
-   - Example: `./device-update.sh firmware-HELTEC-US-0.0.3.bin`.
-
-Note: If you have previously installed meshtastic, you don't need to run this full script instead just run `esptool.py --baud 921600 write_flash 0x10000 firmware-_board_-_country_-_version_.bin`. This will be faster, also all of your current preferences will be preserved.
-

-# What is Meshtastic?
-
-Meshtastic™ is a project that lets you use
-inexpensive (\$30 ish) GPS radios as an extensible, long battery life, secure, mesh GPS communicator. These radios are great for hiking, skiing, paragliding - essentially any hobby where you don't have reliable internet access. Each member of your private mesh can always see the location and distance of all other members and any text messages sent to your group chat.
-
-The radios automatically create a mesh to forward packets as needed, so everyone in the group can receive messages from even the furthest member. The radios will optionally work with your phone, but no phone is required.
-
-Note: Questions after reading this? See our new [forum](https://meshtastic.discourse.group/).
-
-### Uses
-
-- Outdoor sports where cellular coverage is limited. (Hiking, Skiing, Boating, Paragliding, Gliders etc..)
-- Applications where closed source GPS communicators just won't cut it (it is easy to add features for glider pilots etc...)
-- Secure long-range communication within groups without depending on cellular providers
-- Finding your lost kids ;-)
-- Through our [python API](https://pypi.org/project/meshtastic/) use these inexpensive radios to easily add mesh networking to your own projects.
-
-[![Youtube video demo](desk-video-screenshot.png)](https://www.youtube.com/watch?v=WlNbMbVZlHI "Meshtastic early demo")
-
-### Features
-
-Not all of these features are fully implemented yet - see **important** disclaimers below. But they should be in by the time we decide to call this project beta (three months?)
-
-- Very long battery life (should be about eight days with the beta software)
-- Built in GPS and [LoRa](https://en.wikipedia.org/wiki/LoRa) radio, but we manage the radio automatically for you
-- Long range - a few miles per node but each node will forward packets as needed
-- Secure - channels are encrypted by AES256 (But see important disclaimers below wrt this feature)
-- Shows direction and distance to all members of your channel
-- Directed or broadcast text messages for channel members
-- Open and extensible codebase supporting multiple hardware vendors - no lock in to one vendor
-- Communication API for bluetooth devices (such as our Android app) to use the mesh. An iOS application is in the works.  And [Meshtastic-python](https://pypi.org/project/meshtastic/) provides access from desktop computers.
-- Very easy sharing of private secured channels. Just share a special link or QR code with friends and they can join your encrypted mesh
-
-This project is currently in beta testing but it is fairly stable and feature complete - if you have questions please [join our discussion forum](https://meshtastic.discourse.group/).
-
-This software is 100% open source and developed by a group of hobbyist experimenters. No warranty is provided, if you'd like to improve it - we'd love your help. Please post in the [forum](https://meshtastic.discourse.group/).
-
-# Updates
-
-Note: Updates are happening almost daily, only major updates are listed below. For more details see our forum.
-
-- 06/04/2020 - 0.6.7 Beta releases of both the application and the device code are released. Features are fairly solid now with a sizable number of users.
-- 04/28/2020 - 0.6.0 [Python API](https://pypi.org/project/meshtastic/) released. Makes it easy to use meshtastic devices as "zero config / just works" mesh transport adapters for other projects.
-- 04/20/2020 - 0.4.3 Pretty solid now both for the android app and the device code. Many people have donated translations and code. Probably going to call it a beta soon.
-- 03/03/2020 - 0.0.9 of the Android app and device code is released. Still an alpha but fairly functional.
-- 02/25/2020 - 0.0.4 of the Android app is released. This is a very early alpha, see below to join the alpha-testers group.
-- 02/23/2020 - 0.0.4 release. Still very bleeding edge but much closer to the final power management, a charged T-BEAM should run for many days with this load. If you'd like to try it, we'd love your feedback. Click [here](https://github.com/meshtastic/Meshtastic-esp32/blob/master/README.md) for instructions.
-- 02/20/2020 - Our first alpha release (0.0.3) of the radio software is ready brave early people.

-
-If you'd like to help with development, the source code is [on github](https://github.com/meshtastic/Meshtastic-Android).
-
-## Supported hardware
-
-We currently support two brands of radios. The [TTGO T-Beam](https://www.aliexpress.com/item/4000119152086.html) and the [Heltec LoRa 32](https://heltec.org/project/wifi-lora-32/). Most people should buy the T-Beam and a 18650 battery (total cost less than \$35). Make
-sure to buy the frequency range which is legal for your country. For the USA, you should buy the 915MHz version. Getting a version that include a screen is optional, but highly recommended.
-
-Instructions for installing prebuilt firmware can be found [here](https://github.com/meshtastic/Meshtastic-esp32/blob/master/README.md).

-# Disclaimers
-
-This project is still pretty young but moving at a pretty good pace. Not all features are fully implemented in the current alpha builds.
-Most of these problems should be solved by the beta release (within three months):
-
-- We don't make these devices and they haven't been tested by UL or the FCC. If you use them you are experimenting and we can't promise they won't burn your house down ;-)
-- The encryption [implementation](software/crypto.md) has not been reviewed by an expert. (Are you an expert? Please help us)
-- A number of (straightforward) software work items have to be completed before battery life matches our measurements, currently battery life is about three days. Join us on chat if you want the spreadsheet of power measurements/calculations.
-- The Android API needs to be documented better
-- No one has written an iOS app yet. But some good souls [are talking about it](https://github.com/meshtastic/Meshtastic-esp32/issues/14) ;-)
-
-For more details see the [device software TODO](https://github.com/meshtastic/Meshtastic-esp32/blob/master/docs/software/TODO.md) or the [Android app TODO](https://github.com/meshtastic/Meshtastic-Android/blob/master/TODO.md).

-# FAQ
-
-If you have a question missing from this faq, please [ask in our discussion forum](https://meshtastic.discourse.group/). And if you are feeling extra generous send in a pull-request for this faq.md with whatever we answered ;-).
-
-## Q: Which of the various supported radios should I buy?
-
-Basically you just need the radio + (optional but recommended) battery. The TBEAM is usually better because it has gps and huge battery socket. The Heltec is basically the same hardware but without the GPS (the phone provides position data to the radio in that case, so the behavior is similar - but it does burn some battery in the phone). Also the battery for the Heltec can be smaller.
-
-In addition to Aliexpress, (banggood.com) usually has stock and faster shipping, or Amazon. If buying a TBEAM, make sure to buy a version that includes the OLED screen - this project doesn't absolutely require the screen, but we use it if is installed.
-
-@claesg has added links to various 3D printable cases, you can see them at (www.meshtastic.org).
-
-## Q: Do you have plans to commercialize this project
-
-Nope. though if some other person/group wanted to use this software and a more customized device we think that would be awesome (as long as they obey the GPL license).
-
-## Q: Does this project use patented algorithms?
-
-(Kindly borrowed from the geeks at [ffmpeg](http://ffmpeg.org/legal.html))
-
-We do not know, we are not lawyers so we are not qualified to answer this. Also we have never read patents to implement any part of this, so even if we were qualified we could not answer it as we do not know what is patented. Furthermore the sheer number of software patents makes it impossible to read them all so no one (lawyer or not) could answer such a question with a definite no. We are merely geeks experimenting on a fun and free project.

-# Medium priority
-
-Items to complete before the first beta release.
-
-- turn on watchdog timer (because lib code seems buggy)
-- show battery level as % full
-- rx signal measurements -3 marginal, -9 bad, 10 great, -10 means almost unusable. So scale this into % signal strength. preferably as a graph, with an X indicating loss of comms.
-
-# Pre-beta priority
-
-During the beta timeframe the following improvements 'would be nice'
-
-- finish DSR for unicast
-- check fcc rules on duty cycle. we might not need to freq hop. https://www.sunfiretesting.com/LoRa-FCC-Certification-Guide/ . Might need to add enforcement for europe though.
-- pick channel center frequency based on channel name? "dolphin" would hash to 900Mhz, "cat" to 905MHz etc? allows us to hide the concept of channel # from hte user.
-- make a no bluetooth configured yet screen - include this screen in the loop if the user hasn't yet paired
-- if radio params change fundamentally, discard the nodedb
-- re-enable the bluetooth battery level service on the T-BEAM
-- implement first cut of router mode: preferentially handle flooding, and change sleep and GPS behaviors
-- provide generalized (but slow) internet message forwarding service if one of our nodes has internet connectivity (MQTT) [ Not a requirement but a personal interest ]
-
-# Low priority
-
-Items after the first final candidate release.
-
-- Change back to using a fixed sized MemoryPool rather than MemoryDynamic (see bug #149)
-- scan to find channels with low background noise? (Use CAD mode of the RF95 to automatically find low noise channels)
-- If the phone doesn't read fromradio mailbox within X seconds, assume the phone is gone and we can stop queing location msgs
-  for it (because it will redownload the nodedb when it comes back)
-- add frequency hopping, dependent on the gps time, make the switch moment far from the time anyone is going to be transmitting
-- assign every "channel" a random shared 8 bit sync word (per 4.2.13.6 of datasheet) - use that word to filter packets before even checking CRC. This will ensure our CPU will only wake for packets on our "channel"
-- the BLE stack is leaking about 200 bytes each time we go to light sleep
-- use fuse bits to store the board type and region. So one load can be used on all boards
-- Don't store position packets in the to phone fifo if we are disconnected. The phone will get that info for 'free' when it
-  fetches the fresh nodedb.
-- Use the RFM95 sequencer to stay in idle mode most of the time, then automatically go to receive mode and automatically go from transmit to receive mode. See 4.2.8.2 of manual.
-- Use fixed32 for node IDs, packetIDs, successid, failid, and lat/lon - will require all nodes to be updated, but make messages slightly smaller.
-- add "store and forward" support for messages, or move to the DB sync model. This would allow messages to be eventually delivered even if nodes are out of contact at the moment.
-- use variable length Strings in protobufs (instead of current fixed buffers). This would save lots of RAM
-- use BLEDevice::setPower to lower our BLE transmit power - extra range doesn't help us, it costs amps and it increases snoopability
-- make a HAM build: just a new frequency list, a bool to say 'never do encryption' and use hte callsign as that node's unique id. -from Girts
-- don't forward redundant pings or ping responses to the phone, it just wastes phone battery
-- don't send location packets if we haven't moved significantly
-- scrub default radio config settings for bandwidth/range/speed
-- show radio and gps signal strength as an image
-- only BLE advertise for a short time after the screen is on and button pressed - to save power and prevent people for sniffing for our BT app.
-- make mesh aware network timing state machine (sync wake windows to gps time) - this can save LOTS of battery
-- split out the software update utility so other projects can use it. Have the appload specify the URL for downloads.
-- read the PMU battery fault indicators and blink/led/warn user on screen
-- discard very old nodedb records (> 1wk)
-- add a watchdog timer
-- handle millis() rollover in GPS.getTime - otherwise we will break after 50 days
-- report esp32 device code bugs back to the mothership via android
-- change BLE bonding to something more secure. see comment by pSecurity->setAuthenticationMode(ESP_LE_AUTH_BOND)

-# Bluetooth API
-
-The Bluetooth API is design to have only a few characteristics and most polymorphism comes from the flexible set of Google Protocol Buffers which are sent over the wire. We use protocol buffers extensively both for the bluetooth API and for packets inside the mesh or when providing packets to other applications on the phone.
-
-## A note on MTU sizes
-
-This device will work with any MTU size, but it is highly recommended that you call your phone's "setMTU function to increase MTU to 512 bytes" as soon as you connect to a service. This will dramatically improve performance when reading/writing packets.
-
-## MeshBluetoothService
-
-This is the main bluetooth service for the device and provides the API your app should use to get information about the mesh, send packets or provision the radio.
-
-For a reference implementation of a client that uses this service see [RadioInterfaceService](https://github.com/meshtastic/Meshtastic-Android/blob/master/app/src/main/java/com/geeksville/mesh/service/RadioInterfaceService.kt).
-
-Typical flow when a phone connects to the device should be the following (if you want to watch this flow from the python app just run "meshtastic --debug --info" - the flow over BLE is identical):
-
-- There are only three relevant endpoints (and they have built in BLE documentation - so use a BLE tool of your choice to watch them): FromRadio, FromNum (sends notifies when new data is available in FromRadio) and ToRadio
-- SetMTU size to 512
-- Write a ToRadio.startConfig protobuf to the "ToRadio" endpoint" - this tells the radio you are a new connection and you need the entire NodeDB sent down.
-- Read repeatedly from the "FromRadio" endpoint. Each time you read you will get back a FromRadio protobuf (see Meshtatastic-protobuf). Keep reading from this endpoint until you get back and empty buffer.
-- See below for the expected sequence for your initial download.
-- After the initial download, you should subscribe for BLE "notify" on the "FromNum" endpoint. If a notification arrives, that means there are now one or more FromRadio packets waiting inside FromRadio. Read from FromRadio until you get back an empty packet.
-- Any time you want to send packets to the radio, you should write a ToRadio packet into ToRadio.
-
-Expected sequence for initial download:
-
-- After your send startConfig, you will receive a series of FromRadio packets. The sequence of these packets will be as follows (but you are best not counting on this, instead just update your model for whatever packet you receive - based on looking at the type)
-- Read a RadioConfig from "radio" - used to get the channel and radio settings
-- Read a User from "user" - to get the username for this node
-- Read a MyNodeInfo from "mynode" to get information about this local device
-- Write an empty record to "nodeinfo" to restart the nodeinfo reading state machine
-- Read a series of NodeInfo packets to build the phone's copy of the current NodeDB for the mesh
-- Read a endConfig packet that indicates that the entire state you need has been sent.
-- Read a series of MeshPackets until it returns empty to get any messages that arrived for this node while the phone was away
-
-For definitions (and documentation) on FromRadio, ToRadio, MyNodeInfo, NodeInfo and User protocol buffers see [mesh.proto](https://github.com/meshtastic/Meshtastic-protobufs/blob/master/mesh.proto)
-
-UUID for the service: 6ba1b218-15a8-461f-9fa8-5dcae273eafd
-
-Each characteristic is listed as follows:
-
-UUID
-Properties
-Description (including human readable name)
-
-8ba2bcc2-ee02-4a55-a531-c525c5e454d5
-read
-fromradio - contains a newly received FromRadio packet destined towards the phone (up to MAXPACKET bytes per packet).
-After reading the esp32 will put the next packet in this mailbox. If the FIFO is empty it will put an empty packet in this
-mailbox.
-
-f75c76d2-129e-4dad-a1dd-7866124401e7
-write
-toradio - write ToRadio protobufs to this characteristic to send them (up to MAXPACKET len)
-
-ed9da18c-a800-4f66-a670-aa7547e34453
-read,notify,write
-fromnum - the current packet # in the message waiting inside fromradio, if the phone sees this notify it should read messages
-until it catches up with this number.
-
-The phone can write to this register to go backwards up to FIXME packets, to handle the rare case of a fromradio packet was dropped after the esp32 callback was called, but before it arrives at the phone. If the phone writes to this register the esp32 will discard older packets and put the next packet >= fromnum in fromradio.
-When the esp32 advances fromnum, it will delay doing the notify by 100ms, in the hopes that the notify will never actally need to be sent if the phone is already pulling from fromradio.
-
-Note: that if the phone ever sees this number decrease, it means the esp32 has rebooted.
-
-Re: queue management
-Not all messages are kept in the fromradio queue (filtered based on SubPacket):
-
-- only the most recent Position and User messages for a particular node are kept
-- all Data SubPackets are kept
-- No WantNodeNum / DenyNodeNum messages are kept
-  A variable keepAllPackets, if set to true will suppress this behavior and instead keep everything for forwarding to the phone (for debugging)
-
-## Protobuf API
-
-On connect, you should send a want_config_id protobuf to the device. This will cause the device to send its node DB and radio config via the fromradio endpoint. After sending the full DB, the radio will send a want_config_id to indicate it is done sending the configuration.
-
-## Other bluetooth services
-
-This document focuses on the core mesh service, but it is worth noting that the following other Bluetooth services are also
-provided by the device.
-
-### BluetoothSoftwareUpdate
-
-The software update service. For a sample function that performs a software update using this API see [startUpdate](https://github.com/meshtastic/Meshtastic-Android/blob/master/app/src/main/java/com/geeksville/mesh/service/SoftwareUpdateService.kt).

-# Build instructions
-
-This project uses the simple PlatformIO build system. You can use the IDE, but for brevity
-in these instructions I describe use of their command line tool.
-
-1. Purchase a suitable radio (see above)
-2. Install [PlatformIO](https://platformio.org/platformio-ide)
-3. Download this git repo and cd into it
-4. Run `git submodule update --init --recursive` to pull in dependencies this project needs.
-5. If you are outside the USA, edit [platformio.ini](/platformio.ini) to set the correct frequency range for your country. The line you need to change starts with `hw_version` and instructions are provided above that line. Options are provided for `EU433`, `EU835`, `CN`, `JP` and `US` (default). Pull-requests eagerly accepted for other countries.
-6. Plug the radio into your USB port
-7. Type `pio run --environment XXX -t upload` (This command will fetch dependencies, build the project and install it on the board via USB). For XXX, use the board type you have (either `tbeam`, `heltec`, `ttgo-lora32-v1`, `ttgo-lora32-v2`).
-8. Platform IO also installs a very nice VisualStudio Code based IDE, see their [tutorial](https://docs.platformio.org/en/latest/tutorials/espressif32/arduino_debugging_unit_testing.html) if you'd like to use it.
-
-## Decoding stack traces
-
-If you get a crash, you can decode the addresses from the `Backtrace:` line:
-
-1. Save the `Backtrace: 0x....` line to a file, e.g., `backtrace.txt`.
-2. Run `bin/exception_decoder.py backtrace.txt` (this uses symbols from the
-   last `firmware.elf`, so you must be running the same binary that's still in
-   your `.pio/build` directory).

-# Encryption in Meshtastic
-
-Cryptography is tricky, so we've tried to 'simply' apply standard crypto solutions to our implementation. However,
-the project developers are not cryptography experts. Therefore we ask two things:
-
-- If you are a cryptography expert, please review these notes and our questions below. Can you help us by reviewing our
-  notes below and offering advice? We will happily give as much or as little credit as you wish ;-).
-- Consider our existing solution 'alpha' and probably fairly secure against a not particularly aggressive adversary. But until
-  it is reviewed by someone smarter than us, assume it might have flaws.
-
-## Notes on implementation
-
-- We do all crypto at the SubPacket (payload) level only, so that all meshtastic nodes will route for others - even those channels which are encrypted with a different key.
-- Mostly based on reading [Wikipedia](<https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR)>) and using the modes the ESP32 provides support for in hardware.
-- We use AES256-CTR as a stream cypher (with zero padding on the last BLOCK) because it is well supported with hardware acceleration.
-
-Parameters for our CTR implementation:
-
-- Our AES key is 128 or 256 bits, shared as part of the 'Channel' specification.
-- Each SubPacket will be sent as a series of 16 byte BLOCKS.
-- The node number concatenated with the packet number is used as the NONCE. This counter will be stored in flash in the device and should essentially never repeat. If the user makes a new 'Channel' (i.e. picking a new random 256 bit key), the packet number will start at zero. The packet number is sent
-  in cleartext with each packet. The node number can be derived from the "from" field of each packet.
-- Each BLOCK for a packet has an incrementing COUNTER. COUNTER starts at zero for the first block of each packet.
-- The IV for each block is constructed by concatenating the NONCE as the upper 96 bits of the IV and the COUNTER as the bottom 32 bits. Note: since our packets are small counter will really never be higher than 32 (five bits).
-
-```
-You can encrypt separate messages by dividing the nonce_counter buffer in two areas: the first one used for a per-message nonce, handled by yourself, and the second one updated by this function internally.
-For example, you might reserve the first 12 bytes for the per-message nonce, and the last 4 bytes for internal use. In that case, before calling this function on a new message you need to set the first 12 bytes of nonce_counter to your chosen nonce value, the last 4 to 0, and nc_off to 0 (which will cause stream_block to be ignored). That way, you can encrypt at most 2**96 messages of up to 2**32 blocks each with the same key.
-
-The per-message nonce (or information sufficient to reconstruct it) needs to be communicated with the ciphertext and must be unique. The recommended way to ensure uniqueness is to use a message counter. An alternative is to generate random nonces, but this limits the number of messages that can be securely encrypted: for example, with 96-bit random nonces, you should not encrypt more than 2**32 messages with the same key.
-
-Note that for both stategies, sizes are measured in blocks and that an AES block is 16 bytes.
-```
-
-## Remaining todo
-
-- Have the app change the crypto key when the user generates a new channel

-(Here's some quick tips on installing the device code from OS-X, thanks to @android606)
-
-First time using LoRa for anything, just checking it out.
-
-I bought a T-Beam on eBay, followed the instructions to install the firmware here:
-[https://github.com/meshtastic/Meshtastic-esp32](https://github.com/meshtastic/Meshtastic-esp32)
-
-I'm using a Mac for this, so that might account for differences in the steps to get it working. I just swapped out my SSD last month, I'm using a pretty fresh install of OS X 10.15.3/Catalina.
-
-I got it working fairly smoothly, but there were two hang-ups I thought I'd mention:
-
-1. I am about 0% familiar with Python, so there were some issues getting esptool.py working. Basically, this OS X comes with Python 2.7 and no pip. Pip installed okay, so I used it to install esptool. Esptool appeared to install correctly, but I couldn't get it to work to save my life. Simply typing "esptool.py" doesn't work, and I just don't know enough python to figure out why. For some reason, it installs but isn't in the \$PATH anywhere, and I don't know where it went. Python 2.7 kept giving me warning messages about being old and unsupported, so I figured that might be a hint that I should upgrade.
-
-I ended up doing this:
-
-- brew install pyenv (to install pyenv)
-- pyenv install 3.7.7 (to install and select python 3.7.7)
-- pyenv global 3.7.7 (to select the new version of python)
-- brew install pip (to install pip3)
-- pip3 install --upgrade esptool (note I specifically had to use "pip3", not "pip")
-
-...then I was able to execute esptool.py
-
-2. esptool.py didn't work though, because the virtual com port wasn't showing up as a device. I had to install a driver from Silicon Labs, which I got here:
-   [driver for the CP210X USB to UART bridge from Silicon Labs](https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers)
-
-After I installed that, esptool.py was completely happy and the firmware loaded right up.

-- DONE generalize naive flooding
-- DONE add a max hops parameter, use it for broadcast as well (0 means adjacent only, 1 is one forward etc...). Store as three bits in the header.

-- DONE keep a list of packets waiting for acks
-- DONE for each message keep a count of # retries (max of three). Local to the node, only for the most immediate hop, ignorant of multihop routing.
-- DONE delay some random time for each retry (large enough to allow for acks to come in)

-
-broadcast solution:
-Use naive flooding at first (FIXME - do some math for a 20 node, 3 hop mesh. A single flood will require a max of 20 messages sent)
-Then move to MPR later (http://www.olsr.org/docs/report_html/node28.html). Use altitude and location as heursitics in selecting the MPR set
-
-compare to db sync algorithm?
-
-what about never flooding gps broadcasts. instead only have them go one hop in the common case, but if any node X is looking at the position of Y on their gui, then send a unicast to Y asking for position update. Y replies.
-
-If Y were to die, at least the neighbor nodes of Y would have their last known position of Y.
-
-## approach 1
-
-- send all broadcasts with a TTL
-- periodically(?) do a survey to find the max TTL that is needed to fully cover the current network.
-- to do a study first send a broadcast (maybe our current initial user announcement?) with TTL set to one (so therefore no one will rebroadcast our request)
-- survey replies are sent unicast back to us (and intervening nodes will need to keep the route table that they have built up based on past packets)
-- count the number of replies to this TTL 1 attempt. That is the number of nodes we can reach without any rebroadcasts
-- repeat the study with a TTL of 2 and then 3. stop once the # of replies stops going up.
-- it is important for any node to do listen before talk to prevent stomping on other rebroadcasters...
-- For these little networks I bet a max TTL would never be higher than 3?
-
-## approach 2
-
-- send a TTL1 broadcast, the replies let us build a list of the nodes (stored as a bitvector?) that we can see (and their rssis)
-- we then broadcast out that bitvector (also TTL1) asking "can any of ya'll (even indirectly) see anyone else?"
-- if a node can see someone I missed (and they are the best person to see that node), they reply (unidirectionally) with the missing nodes and their rssis (other nodes might sniff (and update their db) based on this reply but they don't have to)
-- given that the max number of nodes in this mesh will be like 20 (for normal cases), I bet globally updating this db of "nodenums and who has the best rssi for packets from that node" would be useful
-- once the global DB is shared, when a node wants to broadcast, it just sends out its broadcast . the first level receivers then make a decision "am I the best to rebroadcast to someone who likely missed this packet?" if so, rebroadcast
-
-## approach 3
-
-- when a node X wants to know other nodes positions, it broadcasts its position with want_replies=true. Then each of the nodes that received that request broadcast their replies (possibly by using special timeslots?)
-- all nodes constantly update their local db based on replies they witnessed.
-- after 10s (or whatever) if node Y notices that it didn't hear a reply from node Z (that Y has heard from recently ) to that initial request, that means Z never heard the request from X. Node Y will reply to X on Z's behalf.
-- could this work for more than one hop? Is more than one hop needed? Could it work for sending messages (i.e. for a msg sent to Z with want-reply set).
-
-## approach 4
-
-look into the literature for this idea specifically.
-
-- don't view it as a mesh protocol as much as a "distributed db unification problem". When nodes talk to nearby nodes they work together
-  to update their nodedbs. Each nodedb would have a last change date and any new changes that only one node has would get passed to the
-  other node. This would nicely allow distant nodes to propogate their position to all other nodes (eventually).
-- handle group messages the same way, there would be a table of messages and time of creation.
-- when a node has a new position or message to send out, it does a broadcast. All the adjacent nodes update their db instantly (this handles 90% of messages I'll bet).
-- Occasionally a node might broadcast saying "anyone have anything newer than time X?" If someone does, they send the diffs since that date.
-- essentially everything in this variant becomes broadcasts of "request db updates for >time X - for _all_ or for a particular nodenum" and nodes sending (either due to request or because they changed state) "here's a set of db updates". Every node is constantly trying to
-  build the most recent version of reality, and if some nodes are too far, then nodes closer in will eventually forward their changes to the distributed db.
-- construct non ambigious rules for who broadcasts to request db updates. ideally the algorithm should nicely realize node X can see most other nodes, so they should just listen to all those nodes and minimize the # of broadcasts. the distributed picture of nodes rssi could be useful here?
-- possibly view the BLE protocol to the radio the same way - just a process of reconverging the node/msgdb database.

-Use naive flooding at first (FIXME - do some math for a 20 node, 3 hop mesh. A single flood will require a max of 20 messages sent)
-Then move to MPR later (http://www.olsr.org/docs/report_html/node28.html). Use altitude and location as heursitics in selecting the MPR set
-
-compare to db sync algorithm?
-
-what about never flooding gps broadcasts. instead only have them go one hop in the common case, but if any node X is looking at the position of Y on their gui, then send a unicast to Y asking for position update. Y replies.
-
-If Y were to die, at least the neighbor nodes of Y would have their last known position of Y.

-## Initial work items
-
-Minimum items needed to make sure hardware is good.
-
-- set power UICR per https://devzone.nordicsemi.com/f/nordic-q-a/28562/nrf52840-regulator-configuration
-- switch charge controller into / out of performance mode (see 8.3.1 in datasheet)
-- write UC1701 wrapper
-- Test hardfault handler for null ptrs (if one isn't already installed)
-- test my hackedup bootloader on the real hardware
-- Use the PMU driver on real hardware
-- Use new radio driver on real hardware
-- Use UC1701 LCD driver on real hardware. Still need to create at startup and probe on SPI. Make sure SPI is atomic.
-- set vbus voltage per https://infocenter.nordicsemi.com/topic/ps_nrf52840/power.html?cp=4_0_0_4_2
-- test the LEDs
-- test the buttons
-
-## Secondary work items
-
-Needed to be fully functional at least at the same level of the ESP32 boards. At this point users would probably want them.
-
-- DONE get serial API working
-- get full BLE api working
-- make power management/sleep work properly
-- make a settimeofday implementation
-- DONE increase preamble length? - will break other clients? so all devices must update
-- DONE enable BLE DFU somehow
-- report appversion/hwversion in BLE
-- use new LCD driver from screen.cpp. Still need to hook it to a subclass of (poorly named) OLEDDisplay, and override display() to stream bytes out to the screen.
-- we need to enable the external tcxo for the sx1262 (on dio3)?
-- figure out which regulator mode the sx1262 is operating in
-- turn on security for BLE, make pairing work
-- make ble endpoints not require "start config", just have them start in config mode
-- use new PMU to provide battery voltage/% full to app (both bluetooth and screen)
-- do initial power measurements, measure effects of more preamble bits, measure power management and confirm battery life
-- set UICR.CUSTOMER to indicate board model & version
-
-## Items to be 'feature complete'
-
-- check datasheet about sx1262 temperature compensation
-- enable brownout detection and watchdog
-- stop polling for GPS characters, instead stay blocked on read in a thread
-- figure out what the correct current limit should be for the sx1262, currently we just use the default 100
-- put sx1262 in sleepmode when processor gets shutdown (or rebooted), ideally even for critical faults (to keep power draw low). repurpose deepsleep state for this.
-- good power management tips: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf52-designs
-- call PMU set_ADC_CONV(0) during sleep, to stop reading PMU adcs and decrease current draw
-- do final power measurements
-- backport the common PMU API between AXP192 and PmuBQ25703A
-- use the new buttons in the UX
-- currently using soft device SD140, is that ideal?
-- turn on the watchdog timer, require servicing from key application threads
-- nrf52setup should call randomSeed(tbd)
-- implement SYSTEMOFF behavior per https://infocenter.nordicsemi.com/topic/ps_nrf52840/power.html?cp=4_0_0_4_2

-## Things to do 'someday'
-
-Nice ideas worth considering someday...
-
-- enable monitor mode debugging (need to use real jlink): https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/monitor-mode-debugging-with-j-link-and-gdbeclipse
-- Improve efficiency of PeriodicTimer by only checking the next queued timer event, and carefully sorting based on schedule
-- make a Mfg Controller and device under test classes as examples of custom app code for third party devs. Make a post about this. Use a custom payload type code. Have device under test send a broadcast with max hopcount of 0 for the 'mfgcontroller' payload type. mfg controller will read SNR and reply. DOT will declare failure/success and switch to the regular app screen.
-- Hook Segger RTT to the nordic logging framework. https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/debugging-with-real-time-terminal
-- Use nordic logging for DEBUG_MSG
-- use the Jumper simulator to run meshes of simulated hardware: https://docs.jumper.io/docs/install.html
-- make/find a multithread safe debug logging class (include remote logging and timestamps and levels). make each log event atomic.
-- turn on freertos stack size checking
-- Currently we use Nordic's vendor ID, which is apparently okay: https://devzone.nordicsemi.com/f/nordic-q-a/44014/using-nordic-vid-and-pid-for-nrf52840 and I just picked a PID of 0x4403
-- Use NRF logger module (includes flash logging etc...) instead of DEBUG_MSG
-- Use "LED softblink" library on NRF52 to do nice pretty "breathing" LEDs. Don't whack LED from main thread anymore.
-- decrease BLE xmit power "At 0dBm with the DC/DC on, the nRF52832 transmitter draws 5.3mA. Increasing the TX power to +4dBm adds only 2.2mA. Decreasing it to -40 dBm saves only 2.6mA."
-- in addition to the main CPU watchdog, use the PMU watchdog as a really big emergency hammer
-- turn on 'shipping mode' in the PMU when device is 'off' - to cut battery draw to essentially zero
-- make Lorro_BQ25703A read/write operations atomic, current version could let other threads sneak in (once we start using threads)
-- make the segger logbuffer larger, move it to RAM that is preserved across reboots and support reading it out at runtime (to allow full log messages to be included in crash reports). Share this code with ESP32 (use gcc noinit attribute)
-- convert hardfaults/panics/asserts/wd exceptions into fault codes sent to phone
-- stop enumerating all i2c devices at boot, it wastes power & time
-- consider using "SYSTEMOFF" deep sleep mode, without RAM retension. Only useful for 'truly off - wake only by button press' only saves 1.5uA vs SYSTEMON. (SYSTEMON only costs 1.5uA). Possibly put PMU into shipping mode?
-- change the BLE protocol to be more symmetric. Have the phone _also_ host a GATT service which receives writes to
-  'fromradio'. This would allow removing the 'fromnum' mailbox/notify scheme of the current approach and decrease the number of packet handoffs when a packet is received.
-- Using the preceeding, make a generalized 'nrf52/esp32 ble to internet' bridge service. To let nrf52 apps do MQTT/UDP/HTTP POST/HTTP GET operations to web services.
-- lower advertise interval to save power, lower ble transmit power to save power
-- the SX126x class does SPI transfers on a byte by byte basis, which is very ineffecient. Much better to do block writes/reads.

-## Old unorganized notes
-
-## Notes on PCA10059 Dongle
-
-- docs: https://infocenter.nordicsemi.com/pdf/nRF52840_Dongle_User_Guide_v1.0.pdf
-
-- Currently using Nordic PCA10059 Dongle hardware
-- https://community.platformio.org/t/same-bootloader-same-softdevice-different-board-different-pins/11411/9
-
-- To make Segger JLink more reliable, turn off its fake filesystem. "JLinkExe MSDDisable" per https://learn.adafruit.com/circuitpython-on-the-nrf52/nrf52840-bootloader
-
-## Done
-
-- DONE add "DFU trigger library" to application load
-- DONE: using this: Possibly use this bootloader? https://github.com/adafruit/Adafruit_nRF52_Bootloader
-- DONE select and install a bootloader (adafruit)
-- DONE get old radio driver working on NRF52
-- DONE basic test of BLE
-- DONE get a debug 'serial' console working via the ICE passthrough feature
-- DONE switch to RadioLab? test it with current radio. https://github.com/jgromes/RadioLib
-- DONE change rx95 to radiolib
-- DONE track rxbad, rxgood, txgood
-- DONE neg 7 error code from receive
-- DONE remove unused sx1262 lib from github
-- at boot we are starting our message IDs at 1, rather we should start them at a random number. also, seed random based on timer. this could be the cause of our first message not seen bug.
-- add a NEMA based GPS driver to test GPS
-- DONE use "variants" to get all gpio bindings
-- DONE plug in correct variants for the real board
-- turn on DFU assistance in the appload using the nordic DFU helper lib call
-- make a new boarddef with a variant.h file. Fix pins in that file. In particular (at least):
-  #define PIN_SPI_MISO (46)
-  #define PIN_SPI_MOSI (45)
-  #define PIN_SPI_SCK (47)
-  #define PIN_WIRE_SDA (26)
-  #define PIN_WIRE_SCL (27)
-- customize the bootloader to use proper button bindings
-- remove the MeshRadio wrapper - we don't need it anymore, just do everything in RadioInterface subclasses.
-- DONE use SX126x::startReceiveDutyCycleAuto to save power by sleeping and briefly waking to check for preamble bits. Change xmit rules to have more preamble bits.
-- scheduleOSCallback doesn't work yet - it is way too fast (causes rapid polling of busyTx, high power draw etc...)
-- find out why we reboot while debugging - it was bluetooth/softdevice
-- make a file system implementation (preferably one that can see the files the bootloader also sees) - preferably https://github.com/adafruit/Adafruit_nRF52_Arduino/blob/master/libraries/InternalFileSytem/examples/Internal_ReadWrite/Internal_ReadWrite.ino else use https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_fds_usage.html?cp=7_5_0_3_55_3
-- change packet numbers to be 32 bits
