Help Needed: LoRa Point-to-Point Communication on STM32WLE5CCU6

[hashara]

Hi everyone,

I am working on LoRa point-to-point communication using the STM32WLE5CCU6 and trying to run the PingPong example. However, I haven't been successful so far.

I would appreciate any guidance on whether I need to modify any pin configurations or make changes to the PingPong example before uploading it to the MCU. Additionally, I am using this IC in the RAK3172 module. Has anyone here developed their own circuit for it?

Any help or suggestions would be greatly appreciated!

Thank you.

Hello @hashara 

First, the RAK3172 is not an ST product but it is based on an STM32WLE55CC MCU. So, for more details you may contact the manufacturer. But I may recommend you some resources (not tested on my side and not developed or guarantee by ST). For the Ping Pong example you may have a look here. And for a design based on the RAK3172, you can find an example here.

Best Regards.

Hi @STTwo-32,

Thank you so much for your response and for pointing me to those resources!

I understand that the RAK3172 is not an official ST product, but it's great to know that it’s based on the STM32WLE55CC MCU. I’ll definitely check out the links you shared and see how I can adapt them to my setup.

Thanks again for taking the time to help—I really appreciate it!

Best regards,
