Problem with SubGHZ sdk, how would it be solved?

Hello guys, I am trying to use SubGhz_Phy SDK for P2P in STM32CUBEIDE. But , there is a problem with my custom board. When ı use, STM32WL development board, it can work; there is no problem with it (TXDone). But, when ı use my RAK3172 Custom board, it can’t send data and occures TXTimeout. Why is that?

There are some differences in the control of the LoRa transceiver. If you are using the STM32Cube, you have to replace some files.

We have a guide for the STM32 LoRaWAN example in our documentation.

In general, the example codes from STM32 are their responsibility and we cannot give support for it.
