I flashed ESP8266 with AT, NodeMCU and Arduino just to test. In all them I was able to create a connection and web server. All good up to there.

Next step is connect my actual arduino uno to ESP8266 (it is flashed with connection parameters so we have internet on ESP).
I connect UNO to ESP. Connection is OK because I can see over serial (hardware) info coming from ESP.
(PC --> UNO --> ESP --> Internet)

I need a "hello world" example to, lets say, turn on UNO's led from internet. Signal should travel from internet, through ESP to UNO and ACK all the way back.

Any example please on that?

Thanks

Regards

Javier
