在Archlinux上重置蓝牙

有时会发生蓝牙鼠标与笔记本电脑断开连接的情况。关闭/打开鼠标没有帮助。关闭/打开笔记本电脑的蓝牙也无济于事。甚至没有systemctl restart bluetooth.service帮助。

但是，如果我关闭笔记本电脑的盖子进入睡眠状态，并在几秒钟后重新打开笔记本电脑，则与bt鼠标的连接将重新建立，然后一切正常。

同样，重启也无济于事。我必须关闭/打开笔记本电脑的电源

编辑： 根据要求，这是一些调试信息：

$ systemctl status bluetooth.service

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

的输出journalctl -xe相当长。... https://pastebin.com/gViN5Tqp

我认为最简单的方法是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

尝试卸载/加载（modprobe）蓝牙模块。
