ESP8266 Community Forum

I have an ESP8266 + Huzzah from adafruit. I'm using it to monitor a temperature and I do not have access to the board easily so it is running 24-7. I need it to be able to recover from lockups on its own.

I've used 32U4 boards and activated the watchdog timer to reboot the board if a WDT reset hasn't occurred in a set time but the same code does not work for the ESP8266. Is there any example code or data sheets describing how to activate a watchdog timer + hardware reset?

Thanks
Jim

But you might consider a hardware solution where a certain output pin needs to be cycled every once in a while and if it's not, the reset pin is pulled.
