Android-x86 Bluez integration

[Chih-Wei Huang]

Hi all,
As you have probably noticed, the Bluez 5.32 was
integrated to kitkat-x86 to replace bluedroid stack
as a part of the Android-x86 4.4-r3 release.
Many thanks to the Bluez team to make this possible
and Povilas Staniulis / cheatman pointed me
the direction.

I've tested all the devices with Bluetooth chip I have.
Almost all of them work nice.
It's much more stable and usable than before.
I'm very satisfied with the status.

If you have HCI USB based chip with
correct linux driver and firmware,
the 4.4-r3 release should just work for you.
If not, show me the output of
dmesg, lsmod, logcat and hciconfig.

If you have HCI UART bluetooth device,
you may need to configure the UART port
by hciattach or similar tool.
Read the init_hal_bluetooth function of
device/generic/x86/init.sh and see the
T10*TA section as an example.
Send me a patch if you have configured it
successfully.

Known issues:
* Bluetooth in ASUS T100 is still unstable:
Sometimes can't scan any device.
Can pair a Bluetooth speaker but can't play audio.
Probably a driver or firmware issue?

I'll update the lollipop-x86 for the
Bluez integration later.

Hi Chih-Wei,

I've tested android-x86-4.4-r3.iso, just to report that my built in macbook 8,1 bluetooth is not detected...

Could you just try

busybox modprobe btusb
hciconfig

If hciconfig show something (hci0 exists), try
to restart gui

stop; start

and see if bluetooth works.

NB: 1. the internal bluetooth adapter detected succesfully, but it can't scan / find bluetooth device (it can't see my phone)...
       2. i tried to scan/find from my phone, it is detected, but when i tried to pair from my phone it pop up error about "incorrect pin or passkey"

[pstglia]

Tested with a small dongle I have (0a12:0001 - Cambridge Silicon Radio Ltda) and it worked fine.

I could pair it with my Mobile Phone and exchange pics from/to it.

Hi Chih-Wei,

I've run tested by macbook builtin bluetooth adapter with Ubuntu 10.04.02 and my other phone, Samsung GT-N7000.
i've attached screenshot of test. 

[Saipudin Haris]

edit from previous post: not Ubuntu 10.04.02 but Ubuntu 14.04.02 (my bad)

I've also re-run test my macbook builtin bluetooth adapter with Android x86 v4.4-r3 and my other phone, Samsung GT-N7000.

[rbg]

how about etc/modules.blacklist????

aren't they blacklisted by default....???!!!

Oh, they should be removed from the blacklist.
I forgot. Thank you for pointing it out.

Hi Chih-Wei,

I've re-download your android x86 4.4 r3 re-built image and i re-tested it on my macbook internal bluetooth adapter against my GT-N7000 phone. I''ve attached the first test result.

problem:  android x86 4.4 r3 bt can't see my phone or other bluetooth device.

[Saipudin Haris]

Hi Chih-Wei,

this is the the second test result from previous post.

problem:  1. android x86 bluetooth can not send pair request to my GT-N7000,
                   but my GT-N7000 can send pair request to android x86 which then "forced" android x86 to see my GT-N7000.

               2. Pairing can only be established from my GT-N7000 only.

               3. android x86 4.4 r3 bluetooth can not send files to my GT-N7000 or other bluetooth device.

[rbg]

could you look into this known issue on the MacBookPro....cause your using the b43 driver for you WiFi it appears...

http://blog.tkassembled.com/188/macbook-pro-83-bluetooth-issues-on-linux/

hopefully it has been solved but who knows...

[Saipudin Haris]

Hi rbg,

Thanks for the info, All Problem SOLVED! It works like a charm.

That's great.

Please show the result of
cat /sys/class/dmi/id/product_name

I can add the quirk later.

[rbg]

Hey...even a blind squirrel finds an acorn every once in a while!!!!!!!!

the articles I went through trying to locate the issue...

most relevant info seemed to be:

--------------------------------

There seems to be a conflict between the bluetooth module and the b43 wifi. 

The solution is creating /etc/modprobe.d/b43.conf with

the following content:

options b43 btcoex=0

(so I assume this could be rolled into the KitKat / Lollipop code base somehow...

  question is what will it disrupt / cause other issues with???)

Because of the work I had done with the b43 / wl intergration (I emailed Chih-Wei that info)

I knew there was / could be many conflicts with those drivers and other drivers...as I had expressed 

in the android-x86 forums....this is simply one I hadn't seen...BUT I'd bet there are others......

Please apply the attached patch to device/generic/x86
and rebuild the image, or just apply it
to /system/etc/init.sh
(if you've installed it as read-write system)

[Saipudin Haris]

Hi Chih-Wei,

The Patch Works, All Bluetooth Problem SOLVED!
I've also attached the modified init.sh, dmesg & logcat output.

[Mario Holzinger]

Hi All!

I have successfully compiled a current version of kitkat with working bluetooth on my Microsoft Surface Pro 2.

many thanks for that.

did someone work also on the lollipop branch?

did you expect that it is difficult to port or should it be only the change of the repository to BlueZ and maybe minor adjustments

I will begin porting and look how far I come.

However any hint would help me to avoid problems

regards

Mario

No, there should no particular issue to
integrate bluez into the lollipop branch.
I just have no time to do it yet.
