我正在使用 Ubuntu 18.04 LTS,我的笔记本电脑没有扫描其他设备。我尝试连接的所有设备均功能齐全,并可与其他设备和平台配合使用。
我尝试了以下操作:
$ 蓝牙控制
这就是我得到的:
[NEW] Controller 34:23:87:DC:89:A8 Linux [default]
Agent registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# scan on
Discovery started
[CHG] Controller 34:23:87:DC:89:A8 Discovering: yes
[bluetooth]# list
Controller 34:23:87:DC:89:A8 Linux [default]
[bluetooth]# devices
[bluetooth]# exit
Agent unregistered
[DEL] Controller 34:23:87:DC:89:A8 Linux [default]
我尝试了以下解决方案:
更新:输出sudo service bluetooth status
:
● bluetooth.service - Bluetooth service

答案1
我最终发现 Ubuntu 缺少蓝牙驱动程序。
请按照以下步骤操作:
- 下载司机。
- 安装该包。
sudo gdebi ~/Downloads/broadcom-bt-firmware-10.1.0.1115.deb
或者
sudo dpkg -i ~/Downloads/broadcom-bt-firmware-10.1.0.1115.deb
注意:确保使用正确的路径。
- 重启。
