I have no clue at the moment, why this is happening, what exactly is causing it and how to fix it. But we need to do something about this otherwise I see the project at risk. Unfortunately, I can't provide any code that is constantly reproducing it. click. Using WiFi in STA
mode seems to trigger it more frequently. Same for using the Os
optimization flag. Also, it seems to be related to the rmt
driver. At least it can be found in almost every stack trace.
