HP 15-r212nl Ubuntu 14.04 蓝牙找不到设备

我的笔记本电脑上的蓝牙不起作用，即使笔记本电脑上的蓝牙已打开，我也无法用手机找到它。

系统盘输出：

sudo apt-get install git build-essential linux-headers-generic
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
cd ~
git clone -b troy https://github.com/lwfinger/rtl8723au_bt.git
cd rtl8723au_bt-troy
make 
sudo make install

重启

如果更新安装了新内核，而新内核尚不支持您的设备，您的蓝牙可能会失败。当发生这种情况时 

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

然后重启
