ESP8266 Community Forum

I am new user of Esp8266. this is coincidence or the module is broken,I dont know.While I was sending AT commands to it,suddenly it started to send nonsense data continually.even I do power off and power on again,it is doing the same things,always sending data and blue led on it is always blinking.before it was broken,the last At command which I sent was AT+CIUPDATE.can it be because of that?

Yes.

Me too.



I suggest flashing nodemcu and use esplorer to start with.
Avoid the march nodemcu firmwares, use older ones or later from automatic builds.
