几天前，我买了一台 NUC7i3BNK，安装了内核为 4.8 的 Ubuntu 16.04.02。蓝牙无法使用。我的知识不是很深，但我想说是缺少驱动程序。有人有解决方案吗？

Nano Tranceiver 适用于我的无线键盘和鼠标。如果我使用其他无线键盘，则没有区别：

答案1
linux-firmware可以通过从 repos 更新包来安装此 BT 设备的固件yakkety。
可以通过以下方式完成
sudo wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161.1_all.deb
sudo dpkg -i linux-firmware_1.161.1_all.deb
该固件包含所需的ibt-12-16.sfi文件。
很可能该xenial版本也会在一段时间内更新。
答案2
下载缺失的设备固件 ibt-12-16.sfi，复制到 /lib/firmware/intel，重新启动，运行正常。
再次用我的蓝牙连接扬声器听音乐真是太棒了。
我不是 Linux 专家。有人能告诉我这是否是正确的方法吗？
