- Tue Sep 26, 2017 4:44 pm #70330 Soft watchdog reset are in 99% of the cases your code starving the WiFi-stack (with for instance a long delay).
Insert some yield() function in lengthy operations and don't write code that might lock up the processor for longer than 6 seconds.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
