Your phone already has a GPS inside, and now it can be used as an external GPS receiver for your PC.
The idea is straightforward. The App "FlooGPS" on your smartphone will send GPS data to the Bluetooth adapter. Since the adapter works as a standard USB serial port under all common OSs without an additional driver, it works with the existing GPS desktop Apps seamlessly.
