On our Q2687 boards we’ve noticed they appear to periodically reset and then do not respond to any commands handled by the application (i.e. only responds to built-in commands). I’ve yet to take a log, however a CFUN=1 does manage to reset the processor so it can behave as normal.
What could cause the module to reset like that? Heat? Brownout? Memory leak? I’m sending/receiving UDP with the WIP.
It appears to happen more frequently in hotter conditions. Is there a thermal shutdown of some sort?
