Hi,
I searched the forum and could not find a solution to my problem. So I decided to ask it here.
I am developing an application that sends some data to the cloud via MQTT. I receive the data and it works fine. However, after some time, the application restarts and I do not know why. This behaviour can be seen on the lines 86, 127and 163 in the LTE link monitor.
I thought it has some thing to do with deep sleep and tried to prevend deep sleep by changing the power management, but I have no idea if it had any affect.
My other idea was that it may be an exception or a hard fault, and I tried setting CONFIG_REBOOT=n to see if that changes anything, but it doesn't. The compiler just does not change it to false and gives me information that, after looking on the internet, I couldn't do anything with.
Has anyone some tips why is this happening?
