I have a Dell L702X which has been enabled for UEFI via Custom BIOS and I have Windows 8 Pro x64 and Ubuntu 12.10 x64 successfully dual booting on GPT.

I have named my device under Ubuntu with the same visible name under Windows. All devices pair ok under each respective operating system but the pairs are unique and not shared between the two.

I am struggling to find a way to copy in my bluetooth peripheral keys from Windows 8 into Ubuntu 12.10. I can extract the keys from [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys] from Windows but I can't find the "linkkeys" file that is supposedly under /var/lib/blueooth/[deviceid]/ ?

I am guessing the keys are now in a different place or a different method of access (if at all possible)?

Any help would be greatly appreciated.

  1. Use command under windows: psexec -s -i regedit.exe. psexec -->> Download: http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx (See google for more information)

  2. Copy the key from: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\BTHPORT\Parameters\Keys\aa1111111111\bb2222222222 (reg_binary)

  3. Then replace the key in: /var/lib/bluetooth/XXXXXXXXXXXX/linkkeys

I was using 12.04 and find the same problem. I solved it by creating a new "linkkeys" file and fixing the permission in that path /var/lib/bluetooth/AA:11:11:11:11:11/

then replace the link key you get in windows using the correct format "BB:22:22:22:22:22 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 0 6"

After reboot, the bluetooth device should works fine.
