[REQUEST] rtl8723au_bt bluetooth driver for lenovo yoga 13

Question

Hello.
I have a lenovo yoga 13 laptop with 8723 wireless card.
Wifi is working bacause of dkms-8723au-git package. As I know, in 3.15 kernel it will work out of the box and lwfinger will no longer maintain this source code.
Bluetooth is not working and there is no bluetooth driver in aur. It is required to install another package from here https://github.com/lwfinger/rtl8723au_bt.
I cannot build this package, because when I run make command it ends with error make[1]: *** /lib/modules/3.14.4-1-ARCH/build: No such file or directory. Also there was written about no dkms support in code. But I cannot fix it, because I am still noob in Archlinux. And for some reason it is written "Support kernel version 2.6.32~3.13.0" in readme.txt. I have already 3.14.4-1-ARCH kernel.
Could anyone help me to fix that and make aur package for other people to get  bluetooth work on lenovo yoga 13?

I think bluez5 is ok, because when I run bluetoothctl it can detect my cluetooth controller now. However, I cannot start working with it

Ok, it is not powered on. In troubleshooting section in wiki there are some instructions about such situation. I do all as described in wiki:

Could you please tell me where to dig next. Why there is not rfkill command?
