[Q] Backporting bluetooth fixes to CM7?

I'm currently syncing up the TeamRefuse github and will followup with Scott's Github repo's. I've successfully built CM7 and CM7.2 from source in the past. I have a tiny tiny bit of kernel experience, and can run the patch command like a pro.
So, has anyone attempted backporting the bluetooth audio fixes into CM7?
And were the BT fixes in the kernel, userland, or both? Looking through Scott's changelog, it looks to be kernel only - which should simplify things. But I may be missing something obvious.
I don't want to adjust the source any more than I have to. Just stock CM7(.2) with a working bluetooth stack and call it a day.
Thanks!

Surface Pro 3 Android

Hey guys,
I noticed that no one has gotten very far on getting Android (x86/IA) up and running on the SP3. I am here to attempt it, and bring together a collection of resources for those who know more about porting from the Ubuntu Kernel Source Code to the Android Kernel.
I used the Android IA 4.4r-1 Image on USB, and booted to the setup screen, although I was unable to test hardware due to the fact that my Type Cover was not working, the Touchscreen doesn't work, a USB Mouse isn't an option because the USB 3.0 port isn't supported OOB, and Bluetooth isn't testable until after initial setup.
I then tested Android-x86 4.4r1 and used the following instructions to make an installer: http://forum.xda-developers.com/showthread.php?t=2703270
In this version, I got a KP upon efivar loading. I then used Li's modified 4.4 kernel (Post #10 in referenced thread), and booted to the setup screen, same exact situation with unsupported everything.
Here is the link to the Ubuntu Thread:
They have compiled a list of working/non-working in their custom kernel:

Work In Progress
Mostly a complilation of links and patches from elsewhere.
Working
•Type Cover 3 (both keyboard and trackpad)
•Bluetooth
​•3.13 Trusty kernel: partially working after updating the marvell firmware.
​•3.16 Utopic kernel: Works without problems
•Touch screen
•Built-in microphone, speakers, and headphone jack
•Wireless (very unstable so far with both Utopic and Trusty kernels).
Not Working
•Cameras
Untested
•MicroSD reader
•Bluetooth pen
Kernel with Type Cover 3 support (keyboard and touchpad)

Here is info about the modified SP3 kernel: https://github.com/rubiojr/surface3-ubuntu-trusty
Here is the link to the modified Ubuntu Kernel: https://github.com/rubiojr/surface3-kernel
If someone can port the features of this kernel to the Android-IA/x86 Kernel (Either should do, but due to Play Store inclusion, x86 would be preferred), it would be glorious.
On the SP1/2, Android-x86 has support for just about everything except WiFi, Bluetooth, G-Sensors, all OOB/
On the SP1/2, Android-IA has support for everything excluding Bluetooth working (the people who compiled it ported the Linux driver for the WiFi card, and it works great), link found here: http://forum.xda-developers.com/showthread.php?t=2536533

[Feature request] phone/phablet (nexus 7 2013 lte) as bluetooth headset

Can we have nexus 7 2013 lte act as bluetooth headset and have phone book access profile please.....
www.bluez.org they have the whole source code to put this in to any rom, i do not know how to put but someone who knows i think should be straight forward
also there are roms from huifei who manufactures car stereos with bluetooth functionality in them and they are based on android ... http://forum.xda-developers.com/showthread.php?t=2660662
can we have this functionality please in nexus 7 ?

Last I checked, the bluez stack was missing some important Android functionality, so getting this functionality would require sacrificing other capabilities and it would also require a LOT of work.
It would also probably make life a living nightmare for some of our device maintainers.

There is source code available for a product called carpod, and android car head unit which also has this bluetooth functionality... i downloaded the source code, and it has gradle files etc... i have no idea how and what to look in to the source code... any suggestions where to look? how to open the complete source code in android development studio etc?
the link for that source code is under Helpful Links section -->> http://forum.xda-developers.com/showpost.php?p=55200512&postcount=1
i really hope a developer can just add this functionality which is already implemented in many available car head units running on android...

Is it possible? Yes.
Is it more work than we have time for? Absolutely
To do so would involve either adding a new profile to the Android BT stack (none of us have any familiarity with it) or dropping in BlueZ, which has some really nifty features (such as native DualShock controller support), but its support for other important features (like Bluetooth LE) is, if you read their changelogs, a heavy work in progress and experimental. Which means that if we did this for your niche feature, we'd break widely used functionality (like communication with Android Wear watches). There's also the fact that EVERY device maintainer would have to make changes to their audio routing configs to support this, and trust me, messing with audio routing is a MASSIVE PAIN IN THE ASS that no one wants to mess with.

Bluetooth Dual Audio ?

Hi All,
Has anyone come across simultaneous playback for our device or baked into any roms?
As far as I know and from what I could find it looks like Samsung is the only implementer currently.
Trying to find either an app or if it is something the wonderful devs here can enable?
Thanks in advance

i haven't found any option in lineageos 18.1

Kernel and OS

Hello guys, I've used LineageOS on both my S5 (in 2017) and my S6 (end of 2018 til now) and I have had a great time with it, but it was a bit lacking. Do you have an idea what kernel I should use that is highly customizable and has tons of features (e.g., I can use my phone as a keyboard and mouse on my pc, even in the bios and OS-agnostic). What OS (I prefer official roms over unofficial (ports)) and kernel would you at xda recommend me?
