Hi!
I'm testing RTL8723BU(available in LM811. USB ID 0bda:b720) WiFi BT USB module.
Kernel version used: 4.1.5. Cross-compiled the Wifi Driver from[1] it worked fine.
While crosscompiling the driver for BT which is available at[2], there are few
compile time errors:
....

I also tried the recent branches all got the same errors.
Does any one tested RTL8723BU's bluetooth?
I couldn't find any in-tree driver available for RTL8723BU. Is there anything i'm missing or
doing wrong ?

No. I have an RTL8723BU device on order. Once it arrives, I will be able to
test. The vendor BT driver relies on some features that were removed in kernel
4.1. As a proper driver for the Realtek BT devices is in kernel 4.2, I suggest
that you use it, rather than 4.1.

No, there is none. I refuse to submit any code that I have not tested. In
addition, I doubt that the vendor driver will ever be submitted to staging. It
is just too much work to clean up that ugly code. More likely, the device will
be added to the new driver rtl8xxxu that has just been submitted.

Ok, sure will give a try with 4.2

Great! i will also try to test your patch at my end. Is there any latest version of patchset submitted? I found an RFC version[1] after googling? let me know if any latest version of patchest is submitted.
