Are the variables you are sending from RoboRealm being sent in the SmartDashboard table or another table? How have you tested that "The setup on RoboRealm is working"?

The SmartDashboard connection light is indicating a connection to the Server (your robot), it won't be lit up with just another client on the network (e.g. RoboRealm).

Make sure the SmartDashboard is configured properly for your team number and that you are putting at least one variable to the SmartDashboard from your robot code before checking the connection status (this may mean you need to enable your robot in the appropriate mode, depending on the location of your SmartDashboard calls).
