Hi Glenn,

I am not sure I understand your situation. The Windows BT implementation 
needs a paired device in order to work. You said, that you paired the 
device in the beginning. Have you paired the device and it does not work 
for you? If this is the case please create a bug report which also 
states your Windows version and the device you are trying to connect to. 
You can assign the bug report to me.

Olli
