How to UDP

[Schnyde]

My team (2856) wants to send process aiming data on the driverstation/dashboard and then send it back to the robot's cRIO (which runs java) using UDP. Everything I see involving this in threads seems to imply that UDP is a common way of sending data back to the cRIO; however, there doesn't seem to be anything that really says how to do this. I tried using the javadoc to learn, but when I did what it says to do I get a "'datagram' protocol not found" exception. Does anybody know how to UDP in java?

As you've found, UDP is not supported in the squawk JVM that we use. You can either use TCP, or use NetworkTables.

Ok, thanks. I looked into Network Tables; do you know if that is supported by labview? I haven't seen anything on that...

[Joe Ross]

NetworkTables support was added this year to LabVIEW.

Ok, thanks
