Hi,
this is a forum for LabVIEW questions, so I am assuming you are trying to develop a bluetooth application through LabVIEW. The links below talk more about using bluetooth in LabVIEW.
Developing Bluetooth Applications in LabVIEW
How do I make a Bluetooth device work with LabVIEW?
If you are just trying to transfer files between an Android device and Windows, I would suggest looking at an android specific forum.
Thanks!
