Fatal exception 29 when the internet suddenly goes down #31

Closed handgear closed 6 years ago

handgear commented 6 years ago

Hello. First of all thank you for this useful library. I'm testing for internet disconnection situation or situation that AP disappear. It works fine for sudden absent of AP. (it recovers the connection automatically when AP is back) But in case of internet disconnection it has a problem.

This is the log after internet disconnection.

i guess arduinoWebSockets could be the problem though don't know why it dosn't exit from here -> https://github.com/Links2004/arduinoWebSockets/blob/642750e232e3f0dbb23a10c0f12772df0e98b087/src/WebSockets.cpp#L618

Or shoud i ask to Links2004/arduinoWebSockets ?

Hi,

It seems to be a bug from the arduino/esp8266 sdk. I reported a time ago. One user upload a fix for the version 2.3.0. Four days ago they released the 2.4.0 final version and after a quick test the problem was fixed.

Issues reported:

Updated to 2.4.0 and problem solved. (but still can't get disconnected info in loop. other issue for this.)
