ESP8266 Community Forum

Hello,

I use the Arduino IDE to upload a web server sketch to the ESP8266 module and it works great.

I want to send AT commands to the module, because I want to restart it to the default configuration.

Could somebody help me?

Thanks.

Your web server sketch wiped out the original AT firmware, so you cannot send any AT command any longer; that is, unless you write your own AT parser and incorporate it into your sketch.

Ok. It is good to know for the future.

Do you know what should add to the sketch to get AT command again?

Thanks.

It is not something you can just "add" to your sketch: the AT firmware is a completely different code, it cannot be merged with your sketch.
