Super Fast USB to Bluetooth Dongle V4.0
Add Bluetooth capability to your Raspberry Pi with this super fast USB BT 4.0 module. Utilising the CSR8510 chipset, this adapter is backwards compatible with v2.1 and earlier, but also supports the latest v4.0 low energy bluetooth transmission.
Drivers for CSR Bluetooth modules are built into Windows XP/7/8 so you do not need to install any software or download anything: other bluetooth drivers or 'stacks' such as BlueSoleil are not as good as the Windows stack and will cause problems. Just plug it in and let windows auto-install the BT driver! For Linux (Raspberry Pi), use Bluez which works great, simply follow the tutorials below!
We've gotten some reports that these modules share a small pool of MAC addresses, so you may get some with the same MAC. That means you cannot use two of them in the same room/computer or they'll collide the RF data. For most people, you only need one per computer however.
