Have you searched UDP in the libraries page?

I've find this code

void receive( byte[] data ) { // <-- extended handler

println("recu !!"); for (int i=0;i<data.length;i++) print(data[i]); println(); if (data[i]==10000000) println(allumer); }

i receive a binary code in 8 bytes and when i compile my programme i have an error "can not find anything named i" for the line if (data[i]==10000000)

The variable i is defined only for the loop. When the loop ends, the variable "disappears". Even if was still visible, it would have the value of data.length, so it would throw an ArrayIndexOutOfBoundsException...

You can replace this line with:

if (data[data.length - 1]==10000000) println(allumer);
