Ubuntu 18.04.2 LTS 中的蓝牙停止工作

我看到一个奇怪的问题没有未被发现的蓝牙设备重启后。

我将我的机器从 16.04 升级到了 18.04，我很高兴蓝牙可以使用最新版本。

PS：我也尝试了多种解决方案，例如

  1. 重启机器
  2. 通过命令行重启蓝牙
  3. 还复制并运行了前面提到的几个答案中发布的几个命令

以下是蓝牙永久搜索设备的截图

答案1

确保linux-firmware已安装。

控制dmesg | grep Blue你的蓝牙找到他的固件。应该和我的类似Bluetooth: hci0: BCM20702A 如果固件丢失，你可以从git

并将其移动到文件夹中/lib/firmware/brcm/

答案2

是的，我解决了我的蓝牙问题。只花了 5 分钟就解决了。
