Ubuntu连接AirPods耳机

有时想让Ubuntu电脑连接AirPods2耳机，最近重装系统后，遇到无法配对耳机的情况，特此记录下摸索过程，AirPods其他型号没有试过，没设备测试(最近新购买了AirPods Pro 2nd Generation，经测试，二代照这方法也是可以匹配到的)，方法应该大同小异。

首先，更改控制模式为ControllerMode = bredr，可能值为: "dual", "bredr", "le"， 一种不行的话，换其它模式试试

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

其次，重启bluetooth服务

sudo systemctl restart bluetooth.service

此时，如果你的设备，可通过Gnome Settings的bluetooth页直接识别并匹配的话，下面的步骤作用不大，看看就好。

图形界面无法匹配时，终端操作

1. 开启蓝牙交互控制工具（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. 扫描设备 scan on, 扫描的时候按住AirPods2背后的匹配按钮

when you begin scan devices, remeber press the AirPods2 button on the back

[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
[CHG] Device 00:A6:19:18:52:86 RSSI: -69
[NEW] Device 7C:9A:1D:B0:62:02 AirPods
[NEW] Device A4:50:46:BA:7F:49 A4-50-46-BA-7F-49

所在环境设备很多的时候，貌似没有什么好的办法过滤，需要仔细观察自己的设备名，如上所示，我的airpod2设备已经成功识别

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

3. 连接AirPods2 (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
Connection successful
[AirPods]# 

Haha, it works !

4. 看看设备信息(AirPods2 info)

[AirPods]# info 7C:9A:1D:B0:62:02

    Modalias: bluetooth:v004Cp200Fd9047

5. 下次再连时，先通过devices命令查询设备地址，地址会被记住一段时间(此时图形界面连接的方式应该也可以使用)

next time, if your devices offline, just get device address, connect it again

[AirPods]# devices
Device 7C:9A:1D:B0:62:02 AirPods
Device AC:49:DB:4E:39:41 mephisto

以上主要针对图形界面操作无效时的状况，希望对你有所帮助
