I wrote a very simple sketch that sends an UDP message ("LOOPING.") in a loop
It only sends the full message the first time. "LOOPING."
The next is only "ING."
And finally only the dot. "."
All following messages are empty.
The exact same sketch works flowless on an Arduino Uno + Ethernet Shield.
All my libs are up to date.
It IS working, if I do a begin() and stop() before and after every message.
