Is it possible that the changes to bluetooth package affect the driver pairing? What I have tested, the Bt v4 pairing on Ubuntu 12.04 and 12.10 succeeds, but on 14.04 and later not. The differences that could affect the functioning are kernel and bluetooth package - bluez. When I tried to pair with command line on 15.10, the pairing was not successful due to mismatched pin.
