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。
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
bluetooth中SOFT和HARD都是unblocked若不是，则执行
sudo rfkill unblock bluetooth
安装blueman
sudo pacman -S blueman --noconfirm
