UDP connection problem

Hi All
I have a problem with udp connection
I try to connect via ethernet
When I start with ArduCopter-quad -A tcp:192.168.1.155:5760:wait i get
"Waiting for connection on 192.168.1.155:5760 …
connected" everything is OK
but when I start with ArduCopter-quad -A udp:192.168.1.155:14550:wait I get only Raspberry Pi 2 with BCM2709! and I can’t connect
I have no idea what is going on

You have to use the GCS computers IP with udp, not the RPis address. UDP sends out the data to the receipent, while tcp waits for the client to make a connection.

OK
Thx very match
