I thought that as well too, but you set up the roboRIO as the server and the raspberry pi as the client. Also, I tried using roboRIO-2053-frc.local as the ip to connect to, but that didnt work that often, so I just switched to static IP's everywhere. We had no connection issues at competition.

Hello people,
Thank you for your help.
I was trying to test my code, since the roborio is in the bag. How do you think I should test it? Do I need a router?

Do you have a spare roboRIO? If so, set that up and get basic code running. If not, then you might be able to set up the network tables viewer as a server and set your pc as the ip on the raspberry pi side. You probably need a switch for this for the connection to work. I've never done it this way. This is my best guess as I've always had a spare robot.

I don't have a spare robo rio, so if anyone has done this without a roborio, please tell me how you did it. Thanks.

You can test Network Tables without a RoboRIO you just need a Network Tables server. Luckily, the Outline Viewer application has the option to run as a Network Tables server.
