I am trying to pair my new Bose qc35 with my Ubuntu 16.04 machine via bluetooth. I tried this answer but it did not work.
When i go into bluetoothctl i can find the headphones, but when i try and pair i get the following error:
[bluetooth]# pair 04:52:C7:C5:2A:71
Attempting to pair with 04:52:C7:C5:2A:71
[CHG] Device 04:52:C7:C5:2A:71 Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed
[CHG] Device 04:52:C7:C5:2A:71 Connected: no
I have followed the advice in the above answer and set the bluetooth service to use bredr.
I tired trusting the device first and then pairing, but there is the same problem:
[bluetooth]# trust 04:52:C7:C5:2A:71
[CHG] Device 04:52:C7:C5:2A:71 Trusted: yes
Changing 04:52:C7:C5:2A:71 trust succeeded
[bluetooth]# pair 04:52:C7:C5:2A:71
