蓝牙已启用（如所示/proc/acpi/ibm/bluetooth），我已经安装了 bluez/blueman/gnome-applet

当我尝试运行 bt-device 时，我得到了

有任何想法吗 ？

答案1

它看起来像是一个错误bluez-utils： https://github.com/khvzak/bluez-tools/issues/23

提出了解决办法这里是重新加载btusb内核模块。

rmmod btusb
modprobe btusb

答案2

原因是你没有正确的驱动程序来让芯片工作。我的笔记本电脑上也有同样的 Broadcom 设备，相信我，它是市面上最差的网络设备。

原因一是蓝牙和无线网卡合二为一的芯片，二是驱动，我找 Ubuntu 的驱动花了不少时间。

如果有帮助的话，你可以用这个命令在 Ubuntu 中安装驱动程序-

sudo apt-get install bcmwl-kernel-source

（首先您必须通过 更新存储库apt-get update。）

Ubuntu 也是一个基于 Debian 的操作系统，因此二进制文件应该兼容（我不太确定）。您可以在 Debian 中测试此软件包。也许这个技巧会奏效。

答案3

我一直在寻找这个问题并解决它。以下是我的解决方案

  • 硬件：联想 Thinkpad T460s
  • 操作系统：Linux
  • 发行版：
$ uname -a
Linux localhost 5.10.0-19-amd64 #1 SMP Debian 5.10.149-2 (2022-10-21) x86_64 GNU/Linux
