Spontaneous reboots (crossfire) #94

I am experiencing some spontaneous reboots mid flight. Telemetry is coming in via BT (115200) from crossfire @ 10Hz. Either the racker just reboots and sets the new homepoint (somwhere where the Aircraft currently is in the sky) or it enters the CLI mode. Both is pretty unfortunate.

This happens not often but almost every 4-5th flight. I was able to reproduce it just with the OLED, FC and BT module - so the problem seems not to be electrical - most likely a code crash or some bug in the CRSF code or in the Serial Code. Maybe the hight telemetry rate (10-12Hz) is causing some unexpected behavior. I think somehow some code triggering the reboot or CLI mode. Sadly it is almost impossible to reproduce on purpose.

Unfortunately this is a big safety issue and I can't trust the tracker in this state as this can't happen mid-flight.
Ver. 11.0.1. spracingF3 and 11.0.0 naze32 - happening on both. CRSF version 2.42.
