联想 12.04 版蓝牙无法检测设备

我是 Ubuntu 新手，不太擅长这个，但我在我的联想 Z5070和Ubuntu 12.04和3.13 内核全靠我自己。

我的蓝牙无法检测到设备，我blueman也尝试过，但没有用。

因此，我从lsusb等处得到的结果是：

我无法理解我所读到的内容。

答案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有效，因为可能仍然需要第二部分才能使其工作。

我以为需要使用 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

重新启动并查看是否已修复

如果您通过更新获得新内核，蓝牙将失败，直到内核支持 realtek 蓝牙，在此之前，您需要

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

然后你应该能够重新启动并再次使用蓝牙功能

答案2

我将此驱动程序添加到 ppa。“内核”分支应用于较新的内核。

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8723au-bt-dkms

通过这种方式安装的优点是内核更新后驱动程序仍会保留。
