Ok, while you're at it, install wireshark (
http://www.wireshark.org/download.html), and make sure that the packets have the right data:
(do this while the robot is running, and sending "data")
open wireshark
go to Capture>Interfaces...
select your interface (wait to see the one that has incoming packets) by hitting the start next to it
in the Filter text box enter
udp.dstport == 1165 and click apply
after some packets have come in, click one, and make sure it contains (look at the bottom box)
@@@451:|grph=0.5|... (or something similar)
if you see this, you are good, and can close wireshark. if not, report back (and you can close wireshark for the moment)
