ESP8266 Community Forum

Hi, I´m looking to a project that reads the temperature from I2C sensor (is working fine) and sends the data over Wifi AP. The client will be another ESP8266 or a phone App, wich is the easiest way to do this? I´m not trying to do a Webserver, just recive a command from a tcpClient and response it back with the data. Thanks Hope you will help me.

MQTT?

Do you not want to use a web server because you think it will be a PITA or you don't want to use the HTTP or WebSocket protocols?
I can show you how to write that song in maybe ten - twenty lines of code... and write the browser client in another five minutes... If webserver solution is acceptable that is.
