ESP8266 Community Forum

- Mon Apr 02, 2018 2:56 pm #75092 I have implemented chat system via Node.Js, whenever I send a text message from one browser window then from other browser window I can receive the text message, I have used one IP and port, where both browser hits the same IP and port,
Now I want esp8266 to hit the IP and port, and from browser I want to send some data(strings) to control on/off
switch via esp8266. Is it possible?

I want to control esp8266 through Global server with negligible time delay.
Can anyone help me?

Thanks

By the way, use native Websocket object on browser side, socket.io and libraries of that type won't work.

Also, on Assignment.EssayShark you can find similar information or get homework assignment help if you want to practice with this device. In general, there are a lot of different concrete examples on this subject on GitHub (here is another one https://github.com/espruino/Espruino/issues/605).
