I am new to Ubuntu and I am not good at this, but I did a clean install on my Lenovo Z5070 with Ubuntu 12.04 and 3.13 kernel all by myself.

My bluetooth can not detect devices, I have tried blueman as well but it didn't work.

So my results from lsusb etc. are:

Type the following commands in the terminal:

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
sudo make install

Reboot and see if it works as there might still be a second part to get it working.

I thought the lwfinger wifi drivers needed to be used so

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

Reboot and see if it is fixed

If you get a new kernel through updates, bluetooth will fail until a kernel is made with support for the realtek bluetooth, until then you will need to

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

Then you should be able to reboot and have bluetooth functional again

  • Oh! It took a second boot and for the first time it detects the device. The problem now is that it fails to connect on both normal setup and blueman.

  • I added info on installing the wifi drivers that are needed

  • It is now pairing and connecting so your work here is done! I still can't see the connected device in sound settings thus I can not choose to listen from it. I guess this is a totally different issue. Thank you very much for the solution!

  • If you have blueman as a bluetooth manager you will need to sudo pactl load-module module-bluetooth-discover after every boot as a bug in blueman will unload module bluetooth discover. I will also add instructions for what to do after a kernel update

  • What about upstream integration ? I am tracking this at rzr.online.fr/q/ideapad

I added this driver to a ppa. "kernel" branch should be used for newer kernels.

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

The advantage of installing this way is that the driver will stay after kernel updates.
