I don't know if an NXT can be programmed with only free software. When I had one (version 1.0), it required a very buggy proprietary LabVIEW IDE to program it. I have heard of another way to program it, NXC (Not 'Xactly C), but have never used it.
Have you tested the Bluetooth device on the computer with other devices to
make sure it works?
