Asset Tracker V1 Spontaneous reboots

[billywalton]

Hi,

I am running the asset tracker v1 app with a few mods, but it seems to reboot once in a while and I cannot find the cause.

The LOG gives nothing away:

Is there a way to track a reboot cause?

Thanks

Thanks for the feedback, Billy!

Yes, in general the application will restart after a reset. Normally you can prevent this by adding:

CONFIG_RESET_ON_FATAL_ERROR=n

to your prj.conf.

The error handling of the asset tracker is a little bit different, though.

Do you face the same issue when you are running the application without using the debugger?
