The board has been successfully tested with several SX1262 library :
- LoRaWAN Mac protocol: FabienFerrero/basicmac forked from: LacunaSpace/basicmac
Warning: Add the following line in the code to make it work.
#define ARDUINO_STM32L4_LS200
- LoRa Physical layer: StuartsProjects/SX12XX-LoRa
Warning: SPI PINS for SX1262 must be defined
