在 Archlinux 上重置蓝牙

Question

有时会发生我的蓝牙鼠标与笔记本电脑断开连接的情况。关闭/打开鼠标无济于事。关闭/打开我的笔记本电脑蓝牙也无济于事。甚至没有systemctl restart bluetooth.service帮助。

但是，如果我关闭我的笔记本电脑盖子进入睡眠状态并在几秒钟后重新打开它，与 bt 鼠标的连接将重新建立，然后一切正常。

重启也无济于事。我必须关闭/打开笔记本电脑

编辑： 根据要求，这里是一些调试信息：

$ systemctl status bluetooth.service

请考虑Address already in use发生在 bt 鼠标问题前几个小时

输出journalctl -xe很长.... https://pastebin.com/gViN5Tqp

我认为最简单的方法就是bluetoothctl简单地打开和关闭蓝牙控制器本身。

echo -e 'show\npower off\npower on\nquit' | bluetoothctl
