没有可用的默认控制器 蓝牙 Arch Linux

Question

信息

\n

我的蓝牙昨天工作正常，但是当我用 更新所有软件包时yay，我的蓝牙无法连接。今天，我跑了：

\n

sudo pacman -Syu\nyay -Syu\n

\n

现在我的蓝牙无法连接。

\n

当我打开时bluetoothctl，它给了我No default controller available。

\n

另外，您能否向我解释一下您希望我运行的所有命令，因为我对 Arch Linux 或 Linux 操作系统不太了解？感谢任何试图帮助我的人！:)

我也遇到了类似的问题，我通过在内核上卸载和加载蓝牙模块来解决，尝试：

> rmmod btusb
> modprobe btusb

每个命令之间可能需要等待几秒钟。
