Connecting with roboRIO over TCP

[Jaci]

If it hangs, it generally means that the client socket isn't finding (or isn't trying to connect to) the host socket. Double check that your client phone is trying to connect to the host (i.e. it reaches the code that creates the connection), and that you're on the same network.

As a rule of thumb, for things like vision tracking that update on a periodic basis, UDP might be a better idea.
