蓝牙在 12.04 版本的 lenovo 上无法检测到设备

Question

我是 Ubuntu 的新手，对此并不擅长，但我自己在带有Ubuntu 12.04和3.13 内核的Lenovo Z5070上进行了全新安装。

我的蓝牙无法检测设备，我也尝试过blueman，但没有用。

所以我从lsusb等的结果是：

我不明白我在读什么。

Answer 1

在终端中输入以下命令：

sudo apt-get install build-essential linux-headers generic
wget https://github.com/lwfinger/rtl8723au_bt/archive/troy.zip
unzip troy.zip
cd rtl8723au_bt-troy
make
sudo make install

重新启动并查看它是否工作，因为可能仍然有第二部分让它工作。

我认为需要使用 lwfinger wifi 驱动程序，所以

sudo apt-get install git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

重启看看是否修复

如果您通过更新获得新内核，则蓝牙将失败，直到制作出支持 Realtek 蓝牙的内核为止，在此之前您将需要

cd rtl8723au_bt-troy
make clean
make
sudo make install
cd ~/rtlwifi_new
make clean
make
sudo make install

然后您应该能够重新启动并让蓝牙再次发挥作用
