我已经bluez安装了该软件包并且我已经尝试过bluex-utils并且bluez-utils-compat

编辑hci0内核检测到蓝牙控制器，但 bluetoothctl 未找到它。

有谁知道如何解决这个问题？

编辑#2我发现hciconfighci0 已关闭，但如果我运行hciconfig hci0 up它会返回Can't init device hci0: Invalid argument (22)

答案1

您是否拥有 RTL8821CE 无线 + 蓝牙组合？

AUR 包的 Github 上有关于 Arch 的解决方案。 https://github.com/tomaspinho/rtl8821ce/issues/19#issuecomment-451890849

我希望这是由于其他错误而导致的暂时问题，因为有人说它又开始工作了。 https://bugzilla.kernel.org/show_bug.cgi?id=201921#c1
