Juraj,
serverObj is the IP where my server is installed, that is: the IP of my PC in my internal wifi network.
PaulS,
I'm not sure if $_POST is empty, I thought that it was a variable for a single connection, I didn't imagine that it could contain all the POST commands flying on the network. How can I show the data contained in that variable if I'm connecting from the microcontroller? maybe writing all the data inside $_POST to a txt file? or how should I sent that information to the microcontroller to show it throught the terminal? what do you recommend me?
In case I do an iteration to that variable, how is the information stored in there? or it would be just to search for idNetw and netwName inside the variable?
thanks
