We have a production system based on asset_tracker_v2 in V1.7.0 and V2.5.0. it normally connects and publishes fine 24/7. we have many sensors in the field. There are time when the sensor disconnects and fails to reconnect for hours. I have included some logs when in the failure condition. these messages are in red. note: even though it says "... failure rebooting!" the board does NOT reboot. A software reset does not fix the problem. Only a power cycle or multiple power cycles eventually fixes the problem. any ideas what is happening and how I can reconnect again. During the disconnect sensor data as well as alarm information is missing for hours and is permanently lost.
