+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.

 * I think the bigger encryption question is "what does the encryption need to do"? As it stands, an attacker who has yet to capture any of the devices cannot reasonably capture text or location data. An attacker who captures any device in the channel/mesh can read everything going to that device, everything stored on that device, and any other communication within the channel that they captured in encrypted form. If that capability basically matches your expectations, it is suitable for whatever adventures this was intended for, then, based on information publicly available or widely disclosed, the encryption is good. If those properties are distressing (like, device history is deliberately limited and you don't want a device captured today to endanger the information sent over the channel yesterday) we could talk about ways to achieve that (most likely synchronizing time and replacing the key with its own SHA256 every X hours, and ensuring the old key is not retained unnecessarily).
 * Two other things to keep in mind are that AES-CTR does not itself provide authenticity (e.g. an attacker can flip bits in replaying data and scramble the resulting plaintext), and that the current scheme gives some hints about transmission in the size. So, if you worry about an adversary deliberately messing-up messages or knowing the length of a text message, it looks like those might be possible.

 We use a crude/basic cooperative threading system to allow this on any of our supported platforms.  Simply inherit from OSThread and implement runOnce().

+
+	ext_notification_plugin_enabled = 1
+	ext_notification_plugin_alert_message = 1
+    
+Depending on how your external cirtcuit configured is configured, you may need to set the active state to true.
+
+	ext_notification_plugin_active = 1
+	
+## Alert Types
+
+We support being alerted on two events:
+
+1) Incoming Text Message
+
+2) Incoming Text Message that contains the ascii bell character. At present, only the Python API can send an ascii bell character, but more support may be added in the future.
+
+### Bell Character
+
+The bell character is ASCII 0x07. Include 0x07 anywhere in the text message and with ext_notification_plugin_alert_bell enabled, we will issue an external notification.

+# External Hardware
+
+Be mindful of the max current sink and source of the esp32 GPIO. The easiest devices to interface with would be either an LED or Active Buzzer.

+* Active Buzzer
+* Flame thrower
+* Strobe Light
+* Siren
+    
+# Known Problems
+
+* This won't directly support an passive (normal) speaker as it does not generate any audio wave forms.
+* This currently only supports the esp32. Other targets may be possible, I just don't have to test with.

+# About
+
+A simple interface to send messages over the mesh network by sending strings
+over a serial port.
+
+Default is to use RX GPIO 16 and TX GPIO 17.
+
+
+# Basic Usage:
+
+        1) Enable the plugin by setting serialplugin_enabled to 1.
+        2) Set the pins (serialplugin_rxd / serialplugin_rxd) for your preferred RX and TX GPIO pins.
+           On tbeam, recommend to use:
+                RXD 35
+                TXD 15
+        3) Set serialplugin_timeout to the amount of time to wait before we consider
+           your packet as "done".
+        4) (Optional) In SerialPlugin.h set the port to PortNum_TEXT_MESSAGE_APP if you want to
+           send messages to/from the general text message channel.
+        5) Connect to your device over the serial interface at 38400 8N1.
+        6) Send a packet up to 240 bytes in length. This will get relayed over the mesh network.
+        7) (Optional) Set serialplugin_echo to 1 and any message you send out will be echoed back
+           to your device.
+
+# TODO (in this order):
+
+* Define a verbose RX mode to report on mesh and packet infomration.
+        - This won't happen any time soon.
+
+# Known Problems
+
+    * Until the plugin is initilized by the startup sequence, the TX pin is in a floating
+      state. Device connected to that pin may see this as "noise".
+    * Will not work on NRF and the Linux device targets.

+        2) Set the pins (serialplugin_rxd / serialplugin_rxd) for your preferred RX and TX GPIO pins.

+                RXD 35
+                TXD 15
+        3) Set serialplugin_timeout to the amount of time to wait before we consider
+           your packet as "done".
+        4) (Optional) In SerialPlugin.h set the port to PortNum_TEXT_MESSAGE_APP if you want to
+           send messages to/from the general text message channel.
+        5) Connect to your device over the serial interface at 38400 8N1.
+        6) Send a packet up to 240 bytes in length. This will get relayed over the mesh network.
+        7) (Optional) Set serialplugin_echo to 1 and any message you send out will be echoed back
+           to your device.
+
+    TODO (in this order):
+        * Define a verbose RX mode to report on mesh and packet infomration.
+            - This won't happen any time soon.
+
+    KNOWN PROBLEMS
+        * Until the plugin is initilized by the startup sequence, the TX pin is in a floating
+          state. Device connected to that pin may see this as "noise".
+        * Will not work on NRF and the Linux device targets.

+/** Dear pinetab hardware geeks!
+ * 
+ * The current pinetab lora module has a slight bug.  The ch341 part only provides ISR assertions on edges.
+ * This makes sense because USB interrupts happen through fast/repeated special irq urbs that are constantly
+ * chattering on the USB bus.
+ * 
+ * But this isn't sufficient for level triggered ISR sources like the sx127x radios.  The common way that seems to
+ * be addressed by cs341 users is to **always** connect the INT# (pin 26 on the ch341f) signal to one of the GPIO signals
+ * on the part.  I'd recommend connecting that LORA_DIO0/INT# line to pin 19 (data 4) on the pinetab board.  This would
+ * provide an efficent mechanism so that the (kernel) code in the cs341 driver that I've slightly hacked up to see the
+ * current state of LORA_DIO0.  Without that access, I can't know if the interrupt is still pending - which would create
+ * race conditions in packet handling.  
+ * 
+ * My workaround is to poll the status register internally to the sx127x.  Which is expensive because it involves a number of
+ * i2c transactions and many trips back and forth between kernel and my userspace app.  I think shipping the current version
+ * of the pinetab lora device would be fine because I can poll slowly (because lora is slow).  But if you ever have cause to
+ * rev this board.  I highly encourage this small change.
+ * 
+ * Btw - your little "USB lora dongle" is really neat.  I encourage you to sell it, because even non pinetab customers could
+ * use it to easily add lora to rasberry pi, desktop pcs etc...

+@geeksville eink TODO:
+
+soonish:
+DONE hook cdc acm device to debug output
+DONE fix bootloader to use two buttons - remove bootloader hacks
+DONE get second button working in app load
+DONE use tp_ser_io as a button, it goes high when pressed unify eink display classes
+fix display width and height
+clean up eink drawing to not have the nasty timeout hack
+measure current draws
+DONE put eink to sleep when we think the screen is off
+enable gps sleep mode
+turn off txco on lora?
+make screen.adjustBrightness() a nop on eink screens
+
+later:
+enable flash on qspi.
+fix floating point SEGGER printf on nrf52 - see "new NMEA GPS pos"
+add factory/power on self test
+
+feedback to give:
+
+* bootloader is finished
+
+* the capacitive touch sensor works, though I'm not sure what use you are intending for it
+
+* remove ipx connector for nfc, instead use two caps and loop traces on the back of the board as an antenna?
+
+* the i2c RTC seems to talk fine on the i2c bus.  However, I'm not sure of the utility of that part.  Instead I'd be in favor of
+the following:
+
+* move BAT1 to power the GPS VBACKUP instead per page 6 of the Air530 datasheet.  And remove the i2c RTC entirely.
+
+* remove the cp2014 chip.
+
+* I've made the serial flash chip work, but if you do a new spin of the board I recommend:
+connect pin 3 and pin 7 of U4 to spare GPIOs on the processor (instead of their current connections),
+This would allow using 4 bit wide interface mode to the serial flash - doubling the transfer speed! see example here:
+https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/nrf52840_DK/hw_external_memory.html?cp=4_0_4_7_4
+Once again - I'm glad you added that external flash chip.
+
+* Power measurements
+When powered by 4V battery
+
+CPU on, lora radio RX mode, bluetooth enabled, GPS trying to lock.  total draw 43mA
+CPU on, lora radio RX mode, bluetooth enabled, GPS super low power sleep mode.  Total draw 20mA
+CPU on, lora radio TX mode, bluetooth enabled, GPS super low power sleep mode.  Total draw 132mA
+
+Note: power consumption while connected via BLE to a phone almost identical.
+
+Note: eink display for all tests was in sleep mode most of the time.  Current draw during the brief periods while the eink was being drawn was not
+measured (but it was low).
+
+Note: Turning off EINK PWR_ON produces no noticeable power savings over just putting the eink display into sleep mode.
