AT+ Command to reply HTTP GET with error

Postby MK32 » Thu Oct 26, 2017 5:14 am

Hi guys,

I have configured a ESP8266 as web server with AT commands. When the browser connects, it sends me a request GET /favicon.ico to which I want to reply with an ERROR 404 Not Found.

How can i do it in the data packet sent in the response to +IPD?

Thanks for your reply.

You can send data by command AT+CIPSEND.

Yes I know, but the browser interprets it as data, not as an error message

I think AT+CIPSEND sends the TCP data, so you need to make a HTTP packet of your error message "404 Not Found", and then send the HTTP packet by the CIPSEND command.
