DELL,bluetoothctl,开机,没有可用的默认控制器

我刚刚尝试了 Debian,发现我的蓝牙无法工作。我已经安装bluez并显示响应。bluemanbluetoothctlNo default controller available

bluetoothctl
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# power on
No default controller available 

以下是我的硬件状况详细信息:

答案1

我在宏基笔记本电脑上遇到了同样的问题。我所做的就是 grep 输出dmesg

看起来信息最丰富的一行是:

usb 3-1.1: firmware: failed to load ar3k/AthrBT_0x11020000.dfu (-2)

在互联网上寻找我发现这个问答这解决了我的问题。

简而言之:

sudo apt-get install firmware-atheros
bluetooth-sendto ## (and escape to close the window)

第一个安装了我丢失的软件包,第二个触发系统寻找蓝牙设备。当我再次启动时bluetoothctl,它通知我控制器可用,其余的按照大多数文档页面中的描述进行。

答案2

我遇到过同样的问题。经过一番研究发现是驱动没有安装。检查该答案蓝牙在 Debian 10 中不起作用并查看您的驱动程序是否安装正确 =)
