Web Fetch Causes ESP32 to Reboot #15

Closed tonyc770 closed 3 years ago

tonyc770 commented 3 years ago

I have noticed that every so often as the Web Fetch is getting a JPG file from the web (I download and display a weather radar map) every 15 minutes, the ESP32 will reboot because of a WatchDog timer issue.

Here is the output from the Serial Monitor: [HTTP] begin... [HTTP] GET... [HTTP] GET... code: 200 E (1425376) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (1425376) task_wdt: - IDLE0 (CPU 0) E (1425376) task_wdt: Tasks currently running: E (1425376) task_wdt: CPU 0: esp_timer E (1425376) task_wdt: CPU 1: loopTask E (1425376) task_wdt: Aborting. abort() was called at PC 0x400d224b on core 0

Rebooting...

Any ideas?

Thanks,

It looks like a watchdog time-out. I exect there is a long wait for something and the software is looping. Try finding out where this loop is and adding a yield(); to restart the watchdog.

I added an extra yield() function to the main loop() and the function that retrieves the JPG image. That seems to fix the issue with the Watchdog timeout.

Thanks...
