Ubuntu連接AirPods耳機

有時想讓Ubuntu電腦連接AirPods2耳機，最近重裝系統後，遇到無法配對耳機的情況，特此記錄下摸索過程，AirPods其他型號沒有試過，沒設備測試(最近新購買了AirPods Pro 2nd Generation，經測試，二代照這方法也是可以匹配到的)，方法應該大同小異。

首先，更改控制模式爲ControllerMode = bredr，可能值爲: "dual", "bredr", "le"， 一種不行的話，換其它模式試試

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

其次，重啓bluetooth服務

sudo systemctl restart bluetooth.service

此時，如果你的設備，可通過Gnome Settings的bluetooth頁直接識別並匹配的話，下面的步驟作用不大，看看就好。

圖形界面無法匹配時，終端操作

1. 開啓藍牙交互控制工具（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. 掃描設備 scan on, 掃描的時候按住AirPods2背後的匹配按鈕

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

所在環境設備很多的時候，貌似沒有什麼好的辦法過濾，需要仔細觀察自己的設備名，如上所示，我的airpod2設備已經成功識別

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

3. 連接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. 看看設備信息(AirPods2 info)

[AirPods]# info 7C:9A:1D:B0:62:02
Device 7C:9A:1D:B0:62:02 (public)
    Name: AirPods

    UUID: PnP Information           (00001200-0000-1000-8000-00805f9b34fb)

    Modalias: bluetooth:v004Cp200Fd9047

5. 下次再連時，先通過devices命令查詢設備地址，地址會被記住一段時間(此時圖形界面連接的方式應該也可以使用)

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

查看幫助信息，可以試試額外的控制功能，這裏不再演示：

以上主要針對圖形界面操作無效時的狀況，希望對你有所幫助
