蓝牙在 Linux Mint 18 中不起作用

Question

我正在使用 Linux Mint 18，我的蓝牙图标出现了，但在搜索时找不到任何设备。输出为dmesg |grep -i blue

[   12.730623] Bluetooth: Core ver 2.21

如您所见，输出显示BCM.hcd未找到补丁，并且 hci0 命令显示超时

[   13.109889] bluetooth hci0: Direct firmware load for brcm/BCM.hcd failed with error -2
[   13.109895] Bluetooth: hci0: BCM: Patch brcm/BCM.hcd not found

Answer 1

刚刚安装了 Linux Mint 18.1。蓝牙音箱无法配对。

转到软件管理器并安装包“ Blueman ”，然后从“菜单”转到“所有应用程序”，右键单击“蓝牙”，然后单击“卸载”。

Blueman 图标出现在“面板”上，点击它，遵循非常直观的菜单，大约一分钟内我的蓝牙扬声器工作正常。请务必转到“声音设置”并选择扬声器。

很简单。
