Hi everyone,
I've had an electricimp controlling a relay for about 3 years, running the same code without any issue. Recently I had to update the code to remove a couple of deprecated/not-supported-anymore calls and ever since a made the changes, I'm seeing random restarts, pointing the reason is memory error.
I've gone through the code many times, but I don't seem to find anything that could be causing this (maybe an infinite recursion, or some excess memory allocation?).
This is an excerpt of the log; there is a suspicious amount of reconnects, likely those are also resets
Any help would be much appreciated!
Cheers,
David
