# NRF52 TODO
* Possibly switch from softdevice to Apachy Newt: https://github.com/espressif/esp-nimble
https://github.com/apache/mynewt-core - use nimble BLE on both ESP32 and NRF52

## RAK815
### Bootloader
Installing the adafruit bootloader is optional - I think the stock bootloader will work okay for most.
TODO:
- i2c gps comms not quite right
- ble: AdafruitBluefruit::begin - adafruit_ble_task was assigned an invalid stack pointer. out of memory?
- measure power draw
### Bootloader
Install our (temporarily hacked up) adafruit bootloader
