I have some devices running at a customer site with borons and papertrail to see log messages. I often see blocks like this:
What do these errors mean?
Until now, I just ignored them. But today I had a device on my test bench showing a problem similar to something the customer reported and I assume a connection:
The Boron was blinking cyan, which means internet, but no particle cloud. Waiting a long time (~15min), this did not change. After a reboot, the connection could be established normally. The error message was again
[system] ERROR: Failed to load session data from persistent storage.
But additional to the connection problem, the main loop was not working anymore. It should send some data over uart in intervalls, this stopped. I use
SYSTEM_THREAD(ENABLED);, so the main loop should run even with connection problems. I do not use any particle cloud functions or publish.
I am using a third party sim, I had no problems with this provider on Electrons. This is our first Boron project.
Can anyone help me with these error messages? Thank you in advance!
