在 Archlinux 上重置蓝牙

有时我的蓝牙鼠标会与笔记本电脑断开连接。关闭/打开鼠标没有帮助。关闭/打开我的笔记本电脑蓝牙也没有帮助。甚至没有systemctl restart bluetooth.service帮助。

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

重新启动也没有帮助。我必须关闭/打开笔记本电脑的电源

编辑： 根据要求，这里是一些调试信息：

$ systemctl status bluetooth.service

请考虑该问题Address already in use发生在 bt 鼠标问题发生前几个小时

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

答案1

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

答案2

尝试这个： sudo rfkill block bluetooth && sleep 0.1 && sudo rfkill unblock bluetooth;

答案3

尝试卸载/加载 ( modprobe) 蓝牙模块。
