LoraWan with Rak811 - tolialmeida/LORA GitHub Wiki

Rak811 board:

MCU= STM32L151GBU6??? STM32L1xxx6(8/B)A + SX1276 32K RAM 128KB FLASH Create a file

git clone https://github.com/Ebiroll/RAK811_BreakBoard
this page had add all files necesary to compile via platformio: first he want to create new module to platformio: rak811 with stm32 procesador, then there be a file to ststm32 in ~/.platformio/platforms/ if not: pio platform install ststm32. After that make a rak811.json (similar other json into board from ststm32) and cp rak811.json ~/.platformio/platforms/ststm32/boards/rak811.json.
Pio run to compile, the file binary is in .pioenvs/rak811/firmware.bin
Install stm32flash (the before clone there are with file with this program, intro and make, mak install).
All conect is OK??? Conect rak811 uart(3,3v) vcc (3,3v) and gnd: picocom -b 115200 --echo /dev/ttyUSB0 and start on rak811---> can see information from Rak, at+version crtl+m ctr+j to send data.
Go to on a pin 2 PA12--->GpioWrite( &Led1, 1 ); in the main file, compile (pio run)
Turn off RAK, put boot pin (12) to vcc to program it: stm32flash -w .pioenvs/rak811/firmware.bin -v -g 0x0 /dev/ttyUSB0, sometimes no program---> problem with wire....
if all it is ok, measure pin 2 vcc=3,3v *turn off rak,Nor we want to see printout of program: without pin 12 to vcc (to the air), picocom -b 115200 --echo /dev/ttyUSB0 and turn on: you can see Terminal ready LIS3DH no ack LIS3DH is not found! RAK811 BreakBoard soft version: 1.0.2
