蓝牙未检测到任何设备

Question

当尝试通过设备搜索连接到任何设备时，它总是以空的形式结束，即使我的手机、平板电脑和 Bose SoundLink Mini 蓝牙同时打开也是如此。

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

我发现了这个： Ubuntu 没有检测到我的蓝牙接收器，如何解决？

所以这里是我的一切输出：

Answer 1

您可以通过这种方式安装蓝牙驱动

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。
