Hello guys,
I am having problems on addressing an issue with my firmware. Maybe someone can assist me to find out the root cause for this, because I don't understand too much of the error log.
The firmware runs smooth for some time (it varies from time to time, but in most cases it runs for several hours before crash).
See below that the firmware stopped logging to RTT (and it stopped working too) at `[15:12:44.837,554]`. It just freezed.
The output from RTT log is only printed out in the serial monitor if I open GDB Server and close it (I don't understand why this happens too).
I am testing the application by simulating beacons in the NRF Connect app in android, simulating several advertising beacons so that this device can keep scanning.
I am using Bluetooth with whitelisting for scanning devices around.
See the log output below:
