systemctl start bluetooth ``` 现在我们可以使用 *bluetoothctl* 命令来实现配对和连接。 如果在使用这个命令过程中出现问题或想了解*bluetoothctl*的更多帮助，参见 [Bluetooth](/index.php/Bluetooth "Bluetooth")。运行： ``` # bluetoothctl ``` 进入内部命令行提示，然后输入： ``` # power on # agent on # default-agent # scan on ``` 现在让你的蓝牙耳机进入配对模式，它很快就能发现新的设备。如： ``` [NEW] Device 00:1D:43:6D:03:26 Lasmex LBT10 ``` 这里发现了一个名字是"Lasmex LBT10"，对应MAC地址是*00:1D:43:6D:03:26*的设备。接下来我们使用这个MAC地址来配对： ``` # pair 00:1D:43:6D:03:26 ``` 配对成功后，你需要手动连接设备(every time?): ``` # connect 00:1D:43:6D:03:26 ``` 如果一切正常，你现在可以在[PulseAudio](/index.php/PulseAudio "PulseAudio")看到一个独立的输出设备。 **提示：** 设备默认情况下可能是停止的。你可以在[pavucontrol](https://www.archlinux.org/packages/?name=pavucontrol)的"Configuration"标签页里选择配置(*OFF*, A2DP, HFP) 你现在可以通过[pavucontrol](https://www.archlinux.org/packages/?name=pavucontrol)的"Playback"和"Pecording"标签页重定向音频的输入、输出了。 除了[pavucontrol](https://www.archlinux.org/packages/?name=pavucontrol)，这里也可以通过*pacmd*命令来选择配置: ``` # pacmd set-card-profile bluez_card.00_1E_7C_30_86_FA a2dp_sink a2dp_sink -- High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 10, available: yes) headset_head_unit -- Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 20, available: yes) off -- Off (sinks: 0, sources: 0, priority: 0, available: yes) ``` 这里可选择"a2dp_sink"或"headset_head_unit"两种配置，其中"headset_head_unit"可以支持音频输入/输出，"a2dp_sink"只支持输出。 **提示：** 如果shell安装了对应的自动补全包[bash-completion](https://www.archlinux.org/packages/?name=bash-completion)或[zsh-completions](https://www.archlinux.org/packages/?name=zsh-completions)，可以通过tab键快速补全命令 你现在可以停止扫描，并退出*bluetoothctl*命令： ``` # scan off # exit ``` ### 常见问题及解决方案 有很多用户报告 A2DP/蓝牙耳机不能正常工作。 #### 已经选择音频配置，但耳机没有激活，不能重定向音频 音频配置的菜单项在设备还没有成功连接的时候就已经存在了，但它并不能起作用。这个菜单项似乎是在设备被发现的时候就马上创建了。 确认一下bluetoothctl是在root用户下或在sudo环境下执行的；然后手动连接设备。有配置选项可以避免每次都需要手动连接，但是配对和信任并不会导致自动连接。 #### 授权失败导致配对失败 如果配对失败，你可以尝试[disabling SSPMode](https://stackoverflow.com/questions/12888589/linux-command-line-howto-accept-pairing-for-bluetooth-device-without-pin): ``` # hciconfig hci0 sspmode 0 ``` #### 配对成功, 但连接失败 你可能在 *bluetoothctl* 里面看到下面的错误: ``` [bluetooth]# connect 00:1D:43:6D:03:26 Attempting to connect to 00:1D:43:6D:03:26 Failed to connect: org.bluez.Error.Failed ``` 你可以通过以下命令查看日志以进一步定位问题： ``` # systemctl status bluetooth # journalctl -n 20 ``` 你可能会在日志里看到下面类似的信息: ``` bluetoothd[5556]: a2dp-sink profile connect failed for 00:1D:43:6D:03:26: Protocol not available ``` 这是因为没有安装[pulseaudio-bluetooth](https://www.archlinux.org/packages/?name=pulseaudio-bluetooth) 包导致的。 如果确实没有安装，安装一下这个包，然后重启一下[PulseAudio](/index.php/PulseAudio "PulseAudio")。 如果不是因为缺失包导致的， 很可能是PulseAudio没收到消息，一般重启一下PulseAudio就可以解决问题。 注意*bluetoothctl*和PulseAudio不需要在相同的用户下运行，*bluetooth*在root环境下运行，而PulseAudio在用户环境下运行也可以很好的工作。 重启PulseAudio后，不需要重新配对，直接重连即可。 如果重启PulseAudio后，仍然不能正常工作，你需要重新加载 module-bluetooth-discover 模块。 ``` # pactl load-module module-bluetooth-discover ``` 你可以把同样的加载命令添加到 `/etc/pulse/default.pa`，让PulseAudio启动时自动加载。 如果仍然不能正常工作，或者你使用的是系统级别的PulseAudio，下面的模块也需要加载一下(同样可以把他们加到default.pa或system.pa里面): ``` module-bluetooth-policy module-bluez5-device module-bluez5-discover ``` 你可以通过加载PulseAudio的 switch-on-connect 模块，使得蓝牙耳机连接后，自动切换到耳机上。添加如下加载语句: `/etc/pulse/default.pa` ``` # automatically switch to newly-connected devices load-module module-switch-on-connect ``` 同时，你需要告诉*bluetoothctl*信任你的蓝牙耳机，否则你将会看到如下报错： ``` bluetoothd[487]: Authentication attempt without agent bluetoothd[487]: Access denied: org.bluez.Error.Rejected ``` ``` [bluetooth]# trust 00:1D:43:6D:03:26 ``` 重启后，你的蓝牙适配器默认是不会启用的，你需要添加udev规则来启用它： `/etc/udev/rules.d/10-local.rules` ``` # Set bluetooth power up ACTION=="add", SUBSYSTEM=="bluetooth", KERNEL=="hci[0-9]*", RUN+="/usr/bin/hciconfig %k up" ``` #### 连接成功，但不能播放声音 确定你在系统日志里面可以看到如下信息: ``` bluetoothd[5556]: Endpoint registered: sender=:1.83 path=/MediaEndpoint/A2DPSource bluetoothd[5556]: Endpoint registered: sender=:1.83 path=/MediaEndpoint/A2DPSink ``` 如果你可以看到类似的信息，说明蓝牙没有问题，你可以去检查PulseAudio的配置问题了。否则的话，退回来再次确认蓝牙是否已经连接成功。 如果使用的是[GDM](/index.php/GDM "GDM")， PulseAudio 的另外一个实例可能已经启动，并且“捕获”了你的蓝牙连接。这种情况可以通过屏蔽GDM用户的pulseaudio socket来解决： ``` # mkdir -p ~gdm/.config/systemd/user # ln -s /dev/null ~gdm/.config/systemd/user/pulseaudio.socket ``` 需要确保这个文件的用户权限是 `gdm:gdm`， 如果不是，使用 [chown](/index.php/Chown "Chown") 修改。 重启电脑后，PulseAudio的第二个实例将不再启动。 #### UUIDs has unsupported type 在配对的时候，你可能会在*bluetoothctl*看到如下信息: ``` [CHG] Device 00:1D:43:6D:03:26 UUIDs has unsupported type ``` 这种情况很常见，没有影响，可以被忽略。 ## Legacy method: ALSA-BTSCO bluez4相关，不翻译，直接参考英文版本[Bluetooth headset#Legacy method: ALSA-BTSCO](/index.php/Bluetooth_headset#Legacy_method:_ALSA-BTSCO "Bluetooth headset") ## Legacy method: PulseAudio bluez4相关，不翻译，直接参考英文版本[Bluetooth headset#Legacy method: PulseAudio](/index.php/Bluetooth_headset#Legacy_method:_PulseAudio "Bluetooth headset") ## Legacy documentation: ALSA, bluez5 and PulseAudio method 争议章节，不翻译，直接参考英文版本[Bluetooth headset#Legacy documentation: ALSA, bluez5 and PulseAudio method](/index.php/Bluetooth_headset#Legacy_documentation:_ALSA.2C_bluez5_and_PulseAudio_method "Bluetooth headset") ## 在 HSV 和 A2DP 配置间切换 通过下面命令可以很容易的在两者间做切换： ``` # pacmd set-card-profile 2 a2dp_sink ``` 这里2是配置文件的索引，根据实际情况确定。更简单的方法是使用tab键来补全。 ### PulseAudio下A2DP不能工作 #### Socket Interface problem If PulseAudio fails when changing the profile to A2DP with bluez 4.1+ and PulseAudio 3.0+, you can try disabling the Socket interface from `/etc/bluetooth/audio.conf` by removing the line `Enable=Socket` and adding line `Disable=Socket`. #### Gnome with GDM **Note:** 下面的方法在 Gnome 3.16.2 和 PulseAudio 6.0 下已经验证过 在GNOME和GDM下，如果PulseAudio切换到A2DP配置不能正常工作，你需要阻止GDM自己启动一个PulseAudio实例。参照[#连接成功，但不能播放声音](#.E8.BF.9E.E6.8E.A5.E6.88.90.E5.8A.9F.EF.BC.8C.E4.BD.86.E4.B8.8D.E8.83.BD.E6.92.AD.E6.94.BE.E5.A3.B0.E9.9F.B3)操作。 **Note:** 针对这个问题的讨论可以参考 [这里](https://bbs.archlinux.org/viewtopic.php?id=194006) 和 [这里](https://bbs.archlinux.org/viewtopic.php?id=196689) ## Tested headsets | Model | Version | Comments | Compatible | | **Philips SHB9150** | bluez5, pulseaudio 5 | Pause and resume does not work.
