在 Archlinux 上重置藍牙

有時我的藍牙滑鼠會與筆記型電腦斷開連線。關閉/打開滑鼠沒有幫助。關閉/打開我的筆記型電腦藍牙也沒有幫助。甚至沒有systemctl restart bluetooth.service幫助。

但是，如果我關閉筆記型電腦蓋子進入睡眠狀態並在幾秒鐘後重新打開它，則與 bt 滑鼠的連接將重新建立，然後一切正常。

重新啟動也沒有幫助。我必須關閉/打開筆記型電腦的電源

編輯： 根據要求，這裡是一些調試資訊：

$ systemctl status bluetooth.service

請考慮該問題Address already in use發生在 bt 滑鼠問題發生前幾個小時

輸出journalctl -xe很長..... https://pastebin.com/gViN5Tqp

答案1

我認為最簡單的方法就是bluetoothctl簡單地打開和關閉藍牙控制器本身。

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

答案2

嘗試這個： sudo rfkill block bluetooth && sleep 0.1 && sudo rfkill unblock bluetooth;

答案3

嘗試卸載/載入 ( modprobe) 藍牙模組。
