英特尔NUC7i3上的Ubuntu 16.04.2，蓝牙无法正常工作
几天前我买了一台NUC7i3BNK并安装了Ubuntu 16.04.02和Kernel 4.8。 蓝牙不起作用。 我的知识不是很深，但我会说司机不见了。 有没有人有办法解决吗？

下载丢失的设备固件ibt-12-16.sfi，复制到/ lib / firmware / intel，重启，工作正常。
再次使用我的蓝牙连接扬声器听音乐真是太棒了。
我不是Linux专家。 有人可以向我解释这是否是正确的方法？
可以通过更新yakkety repos中的linux-firmware软件包来安装此BT设备linux-firmware 。
它可以通过
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
此固件包含所需的ibt-12-16.sfi文件。
很可能xenial版本会在一段时间内更新。
