No SubGHz interrupt on STM32WLE

[Kampi]

I use a RAK3172 module for a 434 MHz LoRa APRS application but I don´t get a SubGHz interrupt during transmission. The output from my code is the following:

APRS Demo
Application version: V1.3.0
Radio version: V1.3.0

Radio settings
LoRa Bandwidth: 125 kHz
LoRa Spreading factor: 12
LoRa Frequency: 433775000
Device reset...
Initialization successful!
Go

I tested the code before on an STM32WL Nucleo and there it runs fine. So I think there is some issue with the port to the RAK platform.

I add the link to the GitHub repository so you can checkout the complete codebase because ZIP files aren´t allowed.

Thanks for your support!

Hello @Kampi 

As the problem is on a module that use the STM32WL but it is designed by a third party. 

So, it will be better to ask this question on his forum since everything works fine with the STM32WL.

Hi @STTwo-32 

I don´t think it´s a hardware issue because I don´t get a Tx complete interrupt from the SubGHz radio, so the callback isn´t called. So it´s an issue with the STM32WLE.

You may have to ensure that you have correctly migrated your project to the STM32WLE MCU. Refer to the MCUs datasheets and reference manuals.
