使用blueman连接蓝牙设备

之前写过一篇博客介绍如何通过命令行来连接蓝牙耳机,但是这个过程显得很繁琐。

事实上, blueman 给我们提供了一个GUI界面来方便地让我们连接蓝牙设备。

  1. 查看蓝牙状态

    sudo rfkill
    
    ID TYPE      DEVICE      SOFT      HARD
     0 wlan      phy0   unblocked unblocked
     1 bluetooth hci0   unblocked unblocked
    

    确定 bluetoothSOFTHARD 都是 unblocked

    若不是,则执行

    sudo rfkill unblock bluetooth
    
  1. 安装blueman

    sudo pacman -S blueman --noconfirm

  2. 检查bluetooth service是否启动

    sudo systemctl status bluetooth.service
    
    ● bluetooth.service - Bluetooth service
       Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; disabled; vendor preset: disabled)
       Active: active (running) since Sat 2018-05-19 07:57:38 CST; 19min ago
         Docs: man:bluetoothd(8)
     Main PID: 28874 (bluetoothd)
       Status: "Running"
        Tasks: 1 (limit: 4636)
       Memory: 1.8M
       CGroup: /system.slice/bluetooth.service
               └─28874 /usr/lib/bluetooth/bluetoothd
    
    May 19 07:57:37 X61 systemd[1]: Starting Bluetooth service...
    May 19 07:57:37 X61 bluetoothd[28874]: Bluetooth daemon 5.49

    Hint: Some lines were ellipsized, use -l to show in full.
    

    若bluetooth.service没有启动,则启动它

    sudo systemctl start bluetooth.service
    
  3. 启动blueman

    在终端执行

    blueman-applet
    

    就会发现任务栏上出现一个蓝牙的图标了 screenshot-60.png

    点击蓝牙图表之后选择 设备 就能搜索蓝牙设备了 screenshot-61.png
