蓝牙没有检测到任何设备

当试图通过设备搜索连接到任何设备时，它总是空着，即使我同时打开了手机，平板电脑和Bose SoundLink Mini蓝牙。

我试图通过手机找到我的笔记本电脑，而我的手机甚至找不到我的笔记本电脑。 （可见性开启）

我发现这个： Ubuntu没有检测到我的蓝牙接收器，如何修复它？

所以这是我对所有事物的输出：

Answer 1

您可以通过这种方式安装蓝牙驱动程序

 sudo add-apt-repository ppa:hanipouspilot/rtlwifi sudo apt-get update sudo apt-get install rtl8723au-bt-dkms rtlwifi-new-dkms linux-firmware 

并重新启动。

但如果您之前从其他来源安装了Realtek无线驱动程序，则需要先卸载它们。
