Hello all,
I am facing a problem when an ESP module stops responding after some hours of operation. It pass from a couple of hours to 2-3 days before it happens. The module reads temperature data from a ds18b20 sensor every 5 seconds and calculates timeON for a relay. Furthermore, the module is listening to a port and sends the temperature data out (just a few bytes) on request over WIFI.
Trying to investigate it a bit, I to connected to a pc monitoring the output on UART. This is what I got from the terminal:
I guess that the key phrase here is "attempt to call a userd", but googling it did not bring me anywhere.
Will appreciate if anybody shed some light onto this and point me in the right direction.
