- Thu Feb 17, 2022 10:35 am #93684 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.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

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.

3 lines of code = Complete IoT, App, Web Server
w/ GUI Admin Client, Drag & Drop File Manager, OTA Built-In, Access Point Manager,
Performance Metrics, Web Socket Comms, App API, All running on ESP8266...
Even usable on ESP-01S --- Please check it out!
