We are running on a Windows XP system and we're using the NXT-G software. When we have the controller station open and the NXT plugged into the computer, we can connect to the NXT. But when we unplug the USB and try to connect through bluetooth, it will not connect. We are not sure if our USB bluetooth adapter (the jump drive thing) is messed up. I do not believe it is, because it worked on our last computer. We just started using new computer. Could that be a problem? If not, what can we do to get the NXT to connect through bluetooth? Please help. Our competition is only days away.
