Using joystick: Xbox One Controller
Found NXT: Tim fork 0016530A7EAE
Connected to NXT: Tim fork@0016530A7EAE
Connection to NXT timed out.

Any clue as to what is going on ?

Are you running the code on the robot that responds to the requests from the computer? This error means that the program on your computer sent a request to the robot and the robot did not respond.

You have to start the program on the robot before starting the program on the computer. I might add the ability to cleanly connect, disconnect and reconnect (like the FRC system), but it doesn't have that capability at the moment.

That's an OSX problem, not my code, but I'll try to help anyway.

It looks like this is a bug in BlueCove (the bluetooth library) caused by some changes in Mac OS 10.8 and newer. What are your OS and BlueCove versions?

I don't much experience with Mac OS, so Googling might help more than I can.

Solved it, the usb that is i needed to switch this little line of code

 public Robot() {
        // RConsole.open();
        // pilot.steer(90, false);
        // pilot.steer(140, false);
        // pilot.steer(180, false);
        // pilot.steer(0, false);
        final NXTConnection connection = Bluetooth.waitForConnection();
        communication = new CommunicationSlave(connection.openInputStream(), connection.openOutputStream(), new CommunicationHandler() {

to

  public Robot() {
        // RConsole.open();
        // pilot.steer(90, false);
        // pilot.steer(140, false);
        // pilot.steer(180, false);
        // pilot.steer(0, false);
        final NXTConnection connection = USB.waitForConnection();
        communication = new CommunicationSlave(connection.openInputStream(), connection.openOutputStream(), new CommunicationHandler() {

in the robot class, $@#$@#$@# well at the tri controller class
