RAK3172 error when waking up

[Athereos]

Hello, I modified the SubGHz example from ST, and it's sending the message and goes to sleep, but when it wakes up it get's stuck on error handler.

I'm getting stuck on where's the problem but I think it's an issue when it needs to configure the clocks.

That's my consumpion graph that shows the transmission and sleep

Here it wakes up but no transmission and when I debug it it's stuck on error handler.

So the first thing is to determine why it ends up in the error handler.

You could use the IDE's call stack.

Then maybe set a breakpoint before that happens, and see what's occurring.

Maybe add more diagnostic info to your error handler.
