Ubuntu connects AirPods headphones

Sometimes I want to connect the AirPods2 headset to the Ubuntu computer. After recently reinstalling the system, I encountered a situation where the headset could not be paired. I hereby record the exploration process. I have not tried other AirPods models, and have not tested the equipment (recently purchased AirPods Pro 2nd Generation, after Test, the second generation can also be matched according to this method), the method should be similar.

First, change the control mode to ControllerMode = bredr , the possible values ​​are: "dual", "bredr", "le", if one does not work, try another mode

➜  ~ egrep -v '^#|^$' /etc/bluetooth/main.conf
[General]
ControllerMode = bredr
[Policy]
AutoEnable=true

Second, restart the bluetooth service

sudo systemctl restart bluetooth.service

At this point, if your device can be directly identified and matched through the bluetooth page of Gnome Settings, the following steps allmost useless, just take a look.

When the graphical interface cannot be matched, the terminal operation

1. Open the interactive bluetooth control tool

➜  ~ bluetoothctl 
Agent registered
[CHG] Device F4:F5:DB:65:B0:3B RSSI: -73
[CHG] Device 4C:D1:A1:3F:B2:55 RSSI: -79
[CHG] Device 94:87:E0:A1:89:49 RSSI: -72
[CHG] Device A0:A4:C5:04:43:17 RSSI: -77
[CHG] Device B4:CB:57:16:D5:80 RSSI: -82

2. Scan the device through 'scan on', press and hold the match button on the back of AirPods2 while scanning

[bluetooth]# scan on
Discovery started
[NEW] Device 44:66:FC:9C:CC:FC 44-66-FC-9C-CC-FC
[NEW] Device C4:E1:A1:AC:C0:6A C4-E1-A1-AC-C0-6A

[NEW] Device 7C:9A:1D:B0:62:02 AirPods
[NEW] Device A4:50:46:BA:7F:49 A4-50-46-BA-7F-49

When there are many devices in the environment, it seems that there is no good way to filter. You need to carefully observe your device name. As shown above, my airpod2 device has been successfully identified.

[NEW] Device 7C:9A:1D:B0:62:02 AirPods

3. Connect AirPods2

[bluetooth]# connect 7C:9A:1D:B0:62:02
Attempting to connect to 7C:9A:1D:B0:62:02
[CHG] Device 7C:9A:1D:B0:62:02 ServicesResolved: yes
[CHG] Device 7C:9A:1D:B0:62:02 Paired: yes

[AirPods]# 

Haha, it works !

4. Check the device information (AirPods2 info)

5. When connecting again next time, first query the device address through the devices command, and the address will be remembered for a period of time (the graphical interface connection method should also be used at this time)

[AirPods]# devices
