hey don't worry it was a joke 
About my code: actually I don't have any error, it compiles and run without any issue, but the problem is that the server on the listening machine isn't receiving anything....
Is the initialization of your class correct? Is it right I'm initializing it like this:
Udp.begin(receiverPort);
...using receiverPort as argument?
Is the composition of the UDP message correct?
Thank you again
