Diagnosing unknown LoRa-E5-HF module issue

hello @msfujino
I compiled with RadioLib 6.6.0 instead of using RadioLib 7.0.0 I doesn’t have no error. I got a Hex file to flash via ST Link using STM32 programmer.



I successfully flashed master and slave Hex files via cube programmer. I am using custom board. how to map the Arduino code to my custom board Serial monitor pins. Above image I will be Giving Serial monitor Pinout mapping. Plz guide me how to interface Serial monitor to mapping Arduino serial print to my custom board.

I am glad you are able to compile.

Let me explain as you may have misunderstood.
In my project, I don’t use a host controller, but use ST-LINK to flash the sketch directly from PA13,PA14 to the module and run it.

There is a setting in CubeProgrammer to use UART instead of ST-LINK, but I have not tried it.

It can be compiled in 7.0.1. For your information.

hi @msfujino ,

In my project am also using PA13,PA14 to flash the sketch with the help of ST_LINK it will be Running successfully. In my custom board PC0,PC1 uart pin are used for serial monitoring the output. In case by using this PC0,PC1 uart pin I need to change any updates for your example code . Is it possible to Monitor the serial print by using this. or Any other possibilities are there to monitor the output.

If the serial ports are PB6 = TX and PB7 = RX, a serial monitor can be used.
If you use PC0 and PC1, you need to use software serial. Search for “Arduino Software Serial” and you should be able to find the information

Setting example of Grove-LoRa-E5.
