Hallo, i have a kobo glo with GPS on serial port. Sometimes when shutting down the kobo stops and display is frozen. Power 3V3 at serial port stays high. I only can completely shut down when i press long time the on/off button. Then the kobo starts in eReader mode. Turning off/on again kobo boots in lk8000 and all is good. that happens maybe every 10th time. here i have the logfile where the error occurs:

[000043200] ? Dist= 31
[000043201] Inside= 5000
[000061051] FLARM found SW:1.00 HW:1.00 OBS:GXAircom

[000076328] . SaveRecentList: saved 1 recent waypoints
[000077000] . SaveTask : saving </mnt/onboard/LK8000/_Tasks/Default.lkt>

then the display is frozen
kobo stops when saving Task. Net step is to close com-ports

this is the normal log when shutting down:

Status Flarm
V 7.3.1

Hardware is GXAircom on a ESP32 Lora System

Kobo is Kobo mini

i have another Hardware with Kobo Glo, GXAircom, TTGO T-Beam V1.1 ESP32 Lora and GPS NEO 6M
Connected to serial port on kobo and V7.3.2
And there i have the same behavior

Both Systems work very nice, shutdown is the only problem sometimes.

crash with 7.3.2

for me it seems when there is another Fanet device received then crash is more likely ?
