好吧,就在几天前,我知道我的 manjaro 系统上的蓝牙可以正常工作。但现在却不行了。
首先它没有被阻止(虽然现在每次我重新启动时都必须解除阻止)
rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
bluetoothctl
不是特别好
bluetoothctl
[bluetooth]# Agent registered
[bluetooth]# show
No default controller available
[bluetooth]# list
[bluetooth]#
据我所知,蓝牙服务没有任何实际问题
systemctl status bluetooth.service ✔ 46s

我得到了一些东西dmesg
,但我真的不明白它是什么

我尝试让它再次工作,插入了一个 USB 蓝牙适配器,但没有作用。
我也尝试安装一些驱动程序(以前不需要)
yay -S rtl8821ce-dkms-git
我已经重新安装了所有相关bluez
当然,我也尝试过重启,但没有成功
