Bluetooth Dongle
From LinuxMCE
What is the purpose?
If you have Bluetooth in the computer that you will use as a LinuxMCE Media Director, this device turns your mobile phone into a remote control and gives you "follow-me" capabilities--your lighting preferences, media and more can follow you around the house.
Requirements and Compatibility
Runs on both Linux, using the Bluez library, and Windows, using the standard Windows/Widcom drivers. Although it should work with all Bluetooth devices, we always use USB Bluetooth dongles with the CSR chipset for both Windows and Linux. The D-Link DBT-120 and TDK are some of the more common models.
