CC2652 freezes with UART firmware

[Morteza-24]

Hi and thanks for this awesome firmware.

I'm using this firmware on a CC2652 connected to an STM32 for UART data transmission. Initially, everything works flawlessly. However, after some time and after sending and receiving a bunch of messages, the CC2652 freezes and stops working. Even the LED stops blinking every 5 seconds, indicating the processor has completely freezed.

For now I have set up the watch dog timer and the CC2652 is reset each time it freezes. But this is happening quite a lot, like every minute of continuous message exchange.

I have tried so hard to identify a pattern or pinpoint the specific action that triggers this issue but I've been unable to do that. I've tried putting a delay before sending data to CC2652, tried sending data in short intervals, long intervals, tried changing the baud rate, the stop bit etc. but no luck.

I have two different modules for CC2652, RF-BM-2652P2 and RF-BM-2652P4. And both of them have this same behavior.

I would greatly appreciate your assistance in resolving this matter. If you require any additional information, please feel free to let me know.

Thank you so much for your time and support.
