Bluetoothctl set passkey
I just had the same issue. If you press tab twice after agent
you should see a list of available agents; KeyboardOnly
works fine without notifications:
[bluetooth]# agent on # accidentally used wrong agent
Agent registered
[bluetooth]# agent
DisplayOnly DisplayYesNo KeyboardDisplay KeyboardOnly NoInputNoOutput off on
[bluetooth]# agent KeyboardOnly
Agent is already registered # can't use two agents at one
[bluetooth]# agent off # unregister agent
Agent unregistered
[bluetooth]# agent KeyboardOnly # register proper agent
Agent registered
[bluetooth]# pair XX:XX:XX:04:F5:7C
Attempting to pair with XX:XX:XX:04:F5:7C
[CHG] Device XX:XX:XX:04:F5:7C Connected: yes
Request passkey
[agent] Enter passkey (number in 0-999999): 722504
[MoarBacon]# pair XX:XX:XX:04:F5:7C
Attempting to pair with XX:XX:XX:04:F5:7C
[CHG] Device XX:XX:XX:04:F5:7C Paired: yes
Pairing successful
Here is what works thanks to kaylum :
$bluetoothctl
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# discoverable on
Changing discoverable on succeeded
[bluetooth]# pairable on
Changing pairable on succeeded
[bluetooth]# agent NoInputNoOutput
Agent registered
[bluetooth]# default-agent
Default agent request successful
Then I pair the raspberry with my phone from the phone.
