We have Tetrix Motors hooked in an EV3. We just simply want to control the robot by remote control and do this simply using the start test command found in the remote control editor. Our EV3 communicates with the laptop by Bluetooth. When we try to test the teleop for our contoller, a little screen pops up and says, "Invoke Node is not supported on the current target." What does this mean and can anyone help us on how to solve this?
