Where are you testing for the output from the RPi? In the robot code running on the roboRIO?

How is your RPi connected to the roboRIO? Are they both connected to the radio with ethernet cables, for instance?

If so, have you verified the RPi is connected to the roboRIO over the local network? You should be able to SSH into either device and ping the other successfully.

If that's not working then the NetworkTables client on the RPi will not be able to connect to the server on the roboRIO.
