Bluetooth problem

[tarsierspectral]

I don't think there is anything wrong with my bluetooth but something is not right in my OS. I am able to pair with my device (GPS logger/tracker) fine but when I try to use it with any GPS software, including Google Earth it just won't talk to the device. It used to work just fine a week ago. Is there a way to flush all the bluetooth info from the OS as if there was never a bluetooth device connected? I already removed the device several times. Trashed all the com.apple.bluetooth preference files and it still doesn't work. SO I tried a new/different GPS and it's the same problem. The device works fine on my other Mac. Any ideas?
