Hi Everyone, I am looking for a way to push information from a (web) server (in a data center) to an Arduino.
- Arduino (f.ex. Yun) connects to the server. -> Green light -> Connected.
- The Server can f.ex. control an LED by sending 1 or 0. (f.ex. with Ajax? or any API?)
- In case of disconnect, retry connection. -> 1. (No port forwards, so no "regular" server. I guess.)
Basically I am trying to replace HTTP requests once a minute - with an open (listening) connection.
The only thing similar I could find so far is this,.. Unfortunately without explanation! https://www.youtube.com/watch?v=HlGH-uv3kts Does anyone have an Idea on how to go about this? I would be really thankful. Cheers Alex
