蓝牙未检测到任何设备

蓝牙未检测到任何设备

当尝试通过设备搜索连接到任何设备时,结果总是空的,即使我同时打开了手机、平板电脑和 Bose SoundLink Mini 蓝牙。

在此处输入图片描述

我尝试通过手机查找我的笔记本电脑,但我的手机根本找不到我的笔记本电脑。(可视性已开启)


我找到了这个: Ubuntu 无法检测到我的蓝牙接收器,如何解决?

以下是我的所有输出:

你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

然后重新启动。

但是,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。
