Hello, using your SS3B file, I managed to turn the LED on and off, however the messages received via WIFI are sometimes incorrect. Take the next output for example:
Msg Received = +IPD,1,6:LDDOFF
Received msg inside loop = +IPD,1,6:LDDOFF
Waiting....
Msg Received = +IPD,1,6:LEDOFF
Received msg inside loop = +IPD,1,6:LEDOFF
Wifi says : LEDOFF
Waiting....
Msg Received = +IPD,1,5:LEFON
Received msg inside loop = +IPD,1,5:LEFON
Waiting....
I had to send LEDOFF twice and then LEDON again twice from my TCP client, in order for the arduino to receive the right messagses. Do you have any ideas why? (I am pretty sure there weren't any typos when I sent the messages)
