Apparently if things hang for to long watchdog resets board. Was facing this from time to time.

Possible problems:

  • internet not connected;
  • to much delays;
  • to much stuff going on in loop;
  • wi-fi re-connection routine added to loop might be causing it.

According to this Stack Overflow answer: https://stackoverflow.com/questions/51750377/how-to-disable-interrupt-watchdog-in-esp32-or-increase-isr-time-limit

"You should always structure your code so that you do the least work you can in loop() and let it return. When it returns the software that supports your ESP32 application gets to do important housekeeping tasks, and reset the watchdog timer."

I were able to reproduce the problem with good repeatability here are the steps:

  1. burn firmware;
  2. burn spiffs image;
  3. parse initial jason with /updateData;
  4. esp32 login to WiFi and all works well so far;
  5. disconnect power of board (board loses time);
  6. connect to the board thru SoftAP and access thru softAP IP 192.168.4.1;
  7. page starts loading stops half way, watchdog intervenes and reboot board with message above;
  8. enable the wifi, board connects to wifi (gets internet time) and network IP;
  9. page continues loading and problem disappears.
  • Probable solutions:
    I will try to get time from battery powered rtc clock;

I am getting this error in my esp32 devkit v1
How to solve it?

lpgn commented

@Kashyapkoshti can you give more details are you trying to implement this project in to a esp32?

Kashyapkoshti commented

@lpgn i am using DOIT devkit v1 Esp32 for making remote controlled car with wifi. for some days it worked fine but after that i was getting this error every time i power it . i removed esp32 from circuit board but the error is still showing. On esp forum someone suggested me to reflash esp32 but i don't know how to do it.

I believe it was solved removing delays
