蓝牙：未找到适配器

我正在使用蓝牙键盘，一切都运行良好，直到今天。它停止工作了。我的蓝牙小程序显示“未找到适配器”。我有一台华硕 UX303LA。

当使用时sudo service bluetooth status，这是输出：

● bluetooth.service - Bluetooth service
   Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)

hcitool dev没有提供任何设备。

我怎样才能知道出了什么问题？

答案1

我在 ThinkPad X220 上升级后遇到了同样的问题，出现了同样的错误。我已经解决了安装 bluez-utils 的问题：

sudo apt install bluez-utils

答案2

我只需重新启动蓝牙即可摆脱“未找到适配器”的问题： sudo service bluetooth restart。
