Hello,
I have bought LoRaNode151 with STM32, registered a ChipID, downloaded your provided code, adjusted the Commissioning.h to my LORA OTAA parameters and added the macro definition (USE_BAND_868, USE_DEBUGGER) in STM32CubeIDE 1.4.0. I have successfully builded a new release there and successfully downloaded it via STLINK to chip.
But if I connect node via UART-USB modul (RX/TX/GND/VDD3.3V) to my PC and terminal I see NO debbuging information via serial port. I have no connection to LoRaWAN gw as well.
So I’m not able to find a problem out. Could you please help me what check (I have only one node I can 't try a PingPong test) ?
