ubuntu 18.04 终端命令行开启/关闭蓝牙

设置面板的蓝牙开关按钮不好用了, 关了就开不了了, 如何手动开启？看这里．

蓝牙没有声音怎么解决？

我的经历，供参考：

蓝牙连上了但是没有声音, 一通折腾, 横冲直撞满头包… 网上说的什么 a2db.py, 反复折腾PulseAudo, Alsamixer 统统不管用. pulseaudio进程杀也杀不死, 死了又复生.

本来觉得已经无望了, 但我怎么会轻易放弃 ?

解决

遇到这个问题，请首先尝试安装Blueman解决，好用！

$ sudo apt-get install blueman

如果到这已经解决了你的问题，后面的内容就不用看了．以下作为记录，仅供参考．不清楚具体哪些操作起到了作用, 所以尽量列出. 有一些是为了展示当前配置.

# 安装pulseaudio-module-bluetooth，还是没有好

$ sudo apt install pulseaudio-module-bluetooth

# pulseaudio -k不起作用．试了改权限

$ sudo chown -R $USER:$USER $HOME/

# 查看进程，准备杀进程，但是其实是杀不死的

$ ps -e | grep pulse

# 输出:

11681 ? 00:00:00 pulseaudio

11686 ? 00:00:00 pulseaudio

# 尝试杀死

$ sudo killall pulseaudio

# 死而复生

$ ps -e | grep pulse

# 输出：

# 11716 ? 00:00:00 pulseaudio

# 11717 tty2 00:00:00 pulseaudio

# 11718 tty2 00:00:00 pulseaudio

# 11720 ? 00:00:00 pulseaudio

# 11721 ? 00:00:00 pulseaudio

# 根据报错　E: [pulseaudio] core-util.c: XDG_RUNTIME_DIR (/run/user/0) 不属于本进程　再次尝试改权限

$ sudo chown -R xxx /run/user/0

# 安装dkms，本机其实已经安装了dkms: 2.3-3ubuntu9.7

$ sudo apt-get install dkms

# 改pulse配置

$ sudo gedit /etc/pulse/default.pa

# 将　load-module module-udev-detect 改为　load-module module-udev-detect tsched=0

# 终极解决：安装blueman！！！

$ sudo apt-get install blueman

# 从启动器打开blueman，设置如下

blueman设置：

pulseaudio设置１：

pulseaudio设置２：

声音设置：

蓝牙耳机：

当Blueman也不好使…

感谢: https://blog.csdn.net/github_36674178/article/details/84715079, 2020.07.20再一次治好ubuntu18.04连不上蓝牙耳机. blueman也不好使

解决过程:

事先重装更新了一些软件:

$ sudo /etc/init.d/bluetooth stop

$ sudo apt-get purge blueman bluez-utils bluez bluetooth

$ sudo apt-get install blueman bluez:i386 bluetooth

$ sudo apt-get install pulseaudio-module-bluetooth* ubuntu-desktop* unity-control-center*

$ sudo /etc/init.d/bluetooth start

然后按照帖子里的说明手动进行配对和连接, 比什么blueman工具都好用

$ bluetoothctl

[bluetooth]# power on

[bluetooth]# show

# 移除

[bluetooth]# remove AE:28:47:A4:16:48

[bluetooth]# list

# 配对

[bluetooth]# pair AE:28:47:A4:16:48

Attempting to pair with AE:28:47:A4:16:48

Failed to pair: org.bluez.Error.ConnectionAttemptFailed

# 连接

[bluetooth]# connect AE:28:47:A4:16:48

Attempting to connect to AE:28:47:A4:16:48

[CHG] Device AE:28:47:A4:16:48 RSSI: -64

[bluetooth]# connect AE:28:47:A4:16:48

Attempting to connect to AE:28:47:A4:16:48

[CHG] Device AE:28:47:A4:16:48 RSSI: -64

Failed to connect: org.bluez.Error.Failed

[CHG] Device AE:28:47:A4:16:48 RSSI: -75

...

[CHG] Device AE:28:47:A4:16:48 Connected: yes

[CHG] Device AE:28:47:A4:16:48 Trusted: yes

最后终于配对成功, 去设置-声音里切换输出,就可以听到了.

只有一边有声音

先将有声音的那只耳机power offer, 然后尝试看能不能连接上没有声音的另一只. 如果连接成功, 再将关闭电源的那只耳机打开.
