A tip if you want to use a bluetooth mouse (or other device) on a system with dual boot. Out of the box, this doesn't work, at least not with recent Windows versions.
The problem is that each OS creates its own key for the pairing, so the device needs re-pairing when you switch OS.
The easiest way is to grab the key from Microsoft and enter into the correct config file on linux.
- Get psexec for windows: https://technet.microsoft.com/en-us/sysinternals/bb897553.aspx
and place it somewhere convenient
- run cmd as administrator (important)
- cd to the place where you put psexec
- run "psexec -s -i regedit.exe"
- in the registry, go to HKLM\System\CurrentControlSet\services\BTHPORT\Parameters\Keys\<MAC of BT adapter>
- there will be a key named after the MAC of the BT device you want to use, its data is a 16 byte value. Note/copy it
> sudo -i
> cd /var/lib/bluetooth/<MAC of BT adapter>/<MAC of BT device
> nano info (or use an editor of your choice)
under the [LinkKey] section there will be a Key entry, put the 16 byte key from Windows there
As puzzled together from various places, I take no credit.
