蓝牙未配对

蓝牙未配对

我正在尝试配对我的蓝牙耳机,但我只能看到该设备一秒钟,然后它就消失了,其他时候(比如现在)它根本检测不到耳机。我以前能够配对几次,但这次就是无法连接。耳机是索尼 MDR-ZX220BT,我有一台装有 Ubuntu 18.04 的戴尔 Inspiron 5521。我的内核是 4.15.0-43-generic。无线控制器是英特尔公司 Wireless 3160(修订版 83),包含蓝牙。我使用 Windows 7 进行双启动,耳机在那里也无法工作,但后来我安装了英特尔发布的更新驱动程序,耳机工作正常。

这里有一些信息:我之前使用以下命令获取了更多信息,但现在它只是说另一个实例已经在运行。

:~$ blueman-applet --loglevel debug
blueman-applet version 2.0.5 starting
There is an instance already running

我尝试了以下操作:

bluetoothctl
power off
power on
scan on

我得到了这个:

Discovery started

所以我不知道接下来该怎么做。如能得到任何帮助我将不胜感激!
