Ubuntu 17.10 - 升级后无法拾取蓝牙设备

  • 772

将我的 Kubuntu 从 17.04 升级到 17.10 后，它无法再接收任何 bt 设备。

我尝试对我的 bt 键盘、bt 鼠标、bt 扬声器和 android 手机进行 bt。它们都没有显示在下面的窗口中：

在此处输入图像描述

我试过了：

$ lspci -nnk | grep -iA2 net; lsusb; hciconfig -a; dmesg | egrep -i 'blue|firm'

我得到：

  1. Best Answer

    我在内核 4.13.0-16-generic 的 Ubuntu 17.10 上遇到了这个问题。

    我有蓝牙适配器“8087:0a2b Intel Corp.”，并且在您的输出中收到相同的错误：

    $ dmesg | grep -i Blue

Ubuntu Bluetooth 8087 0a2b Intel Failed to disable LE scan status 0x0c

    这是为我解决问题的解决方法。

    1. 编辑iwlwifi.conf

      sudo gedit /etc/modprobe.d/iwlwifi.conf

    2. 将以下行添加到此文件的末尾并保存：

      options iwlwifi bt_coex_active=0

    3. 然后重新启动。

    根据Bug #1729389，这可能是回归内核 4.13 。如果您认为此错误会影响您，则应将自己标记为受影响，以便解决。

    在同一个错误报告中建议的另一种解决方案可能是降级到内核 4.10，但首先尝试上述方法可能更容易。
