Never mind: I’m trying to connect through Bluetooth now and I’ve simply removed the offending lines.
The trouble is, I can’t establish a Bluetooth connection. When I plug the transmitter in, a setup icon with the Bluetooth logo appears on the panel. If I click it, there is an option to set up a new device. And the computer can see the brick—it shows up in the list of devices. But when I try to establish a connection (even with the PIN set to the correct 1234), I am asked to enter a PIN on the brick.
