Bug Description

At least in Beta 1 and Beta 2 of Xubuntu, bluetooth worked fine after installing the latest bluetooth driver from LWfinger (https://github.com/lwfinger/). After the latest kernel release I'm not able to get bluetooth to work anymore.

With Kubuntu (vivid) there was and is no way to get rtl8723au_bt running.

Hardware Lenovo Yoga 11, WiFi = RTL8723 works without any problem but rtl8723au_bt means no external mouse.
In addition to Xubuntu (vivid) the TLP repository with TLP is installed.

Please close the bug report.

The problem in this case was the TLP (linrunner) addition. I'm sorry for that but I had to struggle with bluedevil and KDE, and other (K, X, L) and Ubuntu bluetooth issues.

the bluetooth driver rtl8723au_bt-master from git-hub works fine, wlan driver rtl8723au too.
Wlan driver I inserted into dkms
Unfortunately I didn't managed to integrate bluetooth driver rtl8723au_bt into dkms.
After every kernel update it has to be reinstalled.

So could you please insert driver rtl8723au_bt and rtl8723au into kernel?
So far I know all lenovo yoga notebooks like yoga 11 and 13 are affected by this issue.

best from
