The plan

This page is about the LoRa-E5 module and getting it to work as a LoRaWAN node with Arduino and the BasicMac stack.

  • replace the original "AT" firmware with Arduino based firmware
  • use the BasicMac library for LoRaWAN
  • use platformio as the build system
  • create some basic examples for use as a LoRaWAN node on TheThingsNetwork

Hardware

The hardware is the LoRa-E5 module from seeed studio, contains the STM32WLE5JC:

Overview of pins used on this board (not completely standard): https://wiki.seeedstudio.com/LoRa_E5_mini/#22-gpio-configuration-overview

Programming an STM32 is done with pins SWDIO (PA13), SWCLK (PA14), GND and VCC
