Esp8266 not receiving data from sensor periodically.

A place users can post their projects. If you have a small project and would like your own dedicated place to post and have others chat about it then this is your spot.

You can't send from a server when there is no client connected to a socket.

I tried it already with this kind of connection and I got an example if you're interested. It works well but I couldn't send data back to the esp on a simple TCP Connection except with AT Firmware and a Telnet Connection.

So you have to connect with the Phone/Application to the ESP8266 server constantly because there is also a timeout on keep-alive connections of 1-5minutes, I'm not sure if it's settable to unlimited on both sides.


Hi,

I'm interested in the example you have, currently trying to do exactly this. Please share a github link to the arduino and android. Thanks!
