Hi!
I have programmed this code :
https://github.com/SensorsIot/Internet- ... th-ESP8266
to my Feather ESP8266 Wifi (with little changes, like enabling admin mode).

I can easily connect to that "ESP" AP, but problems starts when I'm requesting (GET) web page... What ever I request, my Feather crashes and watchdoc is resetting the system.

Code: Select all

Starting ESP8266

This same crash happens if I use that original code:
http://www.john-lassen.de/index.php/pro ... -webconfig

of course, this code don't have watchdog, so I need to press RST button my self...

Any idea how to "debug".. Or could my ESP8266 be somehow "faulty"?!?

You should install the EspExceptionDecoder from https://github.com/me-no-dev/EspExceptionDecoder to get more meanful stacktrace where source files and line number will be displayed.

Thank you!
Even I'm not sure that this result will help me much.. But will see!
