The more recent releases of the Bluez bluetooth stack for linux
(the one used in the Android codebase) incorporate nearly all
the full features of bluetooth:
Provided by BlueZ:
A2DP 1.2
AVRCP 1.3
DI 1.3
HDP 1.0
HID 1.0
HFP 1.5
PAN 1.0
SPP 1.1
Of most pressing interest to me right now is AVRCP or Audio/Video
Remote Control Profile. This is what is used by remote devices
controlling what is playing on our phones. Currently gingerbread
(and therefore our sensations) are using AVRCP 1.0 - this is for basic
pause/play, skip/back functionality.
The newer profile AVRCP 1.3 allows the phone to send the remote
control the track metadata as well, so your car or bluetooth headset will
show the 'Now Playing' track name instead of being annoyingly blank or
just saying 'bluetooth'.
So as this blankness has started to really annoy me I am
desperate to know if there are any kernels or Roms where people
have integrated the new Bluez stack (or just have AVRCP 1.3
enabled)?
If there are no existing roms, are there any projects to develop
this for the sensation?
Restoring some functionality that was present in my old nokia
phones (smart & dumb), even in the old WinMo HD2 and most
annoyingly - the iPhone, would hopefully benefit all users of the
sensation.
I noticed that the new Motorola RAZR actually supports AVRCP 1.4,
so is there any way to port that back to us?
Thanks
Bump! I am also interested to know if anything is being developed / updated for the Sensation's BT stack.
Also curious about this as well. I've got a rooted Vizio vtab1008 with Gingerbread, and development on that platform is pretty quiet. The Bluetooth stack it has is terrible (although not nearly as bad as the one on my LG Ally) - it simply can't keep its bearings about itself when trying to use a Motorola Bluetooth stereo headset. Audio skips and stutters annoyingly much of the time (rare to get a "clean" session), and almost completely loses its mind if the device goes to sleep and wakes up while the headset is connected - the connection integrity breaks down so bad it often disconnects itself completely or locks up the Bluetooth stack.
So... that said...
I was interested in finding a way to make this work, if it hasn't yet already been done or proven impossible. Not intimately familiar with the Linux platform inside-and-out, but I've gotten pretty good at it (*almost* had a working build environment compiled on the device itself once - just forgot about it). First thing I can think might be a barrier is if the updated version needs to have all the app-interface core libraries or interfaces to be recompiled under the new BlueZ version's libraries - which may be a PITA, though if I understand the architecture correctly, there's only a handful of higher layers in the stack that would be "touching" BlueZ and be affected. Or am I way off? :/
bump ....
this would be sooo awesome
just buyed an sony ericson mw600 an get the the title information shown up with the CM7 ROM.
Only works with the stock player, but it has AVRCP 1.3
Bump!
AVRCP is ROM reliant? or music player?
Cause I would like to use BT audio streaming between my Sensation (ARHD6.6.3 with faux123 6b5) and my car kit (VW).
Thanks!
I have an HTC Sensation 4G on TMOUS, and I am looking for the same solution here. I am rooted with a stock rom, latest ICS.
Does anyone know how to get AVRCP 1.3 on my phone, or a ROM that supports that profile?
Also, does anyone know if JB will support this newer profile?
Thanks!

Hi Guys,
I have been on the search to find a bluetooth headphone that will allow you to listen to music through bluetooth on your I-mate/XDA 2 etc.
I came accross the Sonorix OBH-0100.
Site:http://www.sonorix.com/eng/sono_product_obh0100.html
Review:http://www.worldofppc.com/HWTests/openbt2.htm
I sent an e-mail to the company asking whether this set would work with Pocket PC (XDA 2). They replied back saying that current pocket pc's would need a A2DP (advanced audio distribution profile) to be able to use your bluetooth headphones to listen to music from your device.
Does anyone know how we could go about adding this extra bluetooth feature.
Im sure that alot of you would like this option / accessory. So if anyone could help that would be appreciated.
Thanks
Hi, well done on finding the BT headphones, I've been trying to find something like this for a while...
first, on other parts of this site there are links to the following place:
http://bluetooth.i-networx.de/index_e.html
This guy is busy writing BT software for the XDA to fill in the shortfalls, and slowly including more profiles into his BT tools, He may be able to help with the profile problem for the XDA...
Also, are they actually selling these units yet? The URL you supplied only seems to supply 'sample' sets for traders, I would like to know where it is being sold, and if not when it is being released if the info is available..
http://forum.xda-developers.com/viewtopic.php?t=6816&highlight=bluetooth+stereo
people say that the quality is horrible if it worked
Hmm I dunno, maybe it is possible to send the audio across the BT link compressed (maybe MP3 like) and do the decompression back into audio locally, this would possibly make it possible to send resonable quality over the BT link bitrate (I think it's about 700k).
Their website claims to have reached CD quality audio.
yeah suppose you could do that but it would require
a uncompression in the head set
it would be possible of cause but from that guy who tried it
it may require more then just a std profile
Yes, a special profile is required as mentioned in the first post, apparently it is an advanced audio digital profile (a2dp), but no hand held units have it yet, we were hoping someone may be able to write profile support for the XDA...
I sent an e-mail to Tobias at Pocket Bluetooth tools about these particular headphones and he replied that he has no ordered the headphones and will work on the A2DP profile as soon as he recieves the headphones.
Hope something good comes out of this.
Will keep you updated 8)
Great news, now we only need to sit back and wait.
I had a look at the site but they only seem to be selling trader samples? Do we know where these items can be bought yet and how much? if not do we know a release date?
No, they havent mentioned anything about a release date but I have heard that many people have ordered the trade samples to test them out.
I think trade samples is the ony way you can buy for the time being ...$220 is the price as I remember and this excludes delivery and tax that you might have to pay.
But I have to admit they look very cool and if Tobias can solve this problem soon, I would certainly order one for myself.
BT audio transport
Hi folks,
I'm on the search for BT headset that also plays back the audio output of my MDA II (e.g. direction info of tomtom nav 3 ...)´. When I found this thread I thought that's it, but there is now follow up after Apr. 24th.
Any news yet?
Still no news!?!?!?!
:x
what you need is a bluetooth profile which have support for
Advanced Audio Distribution Profile
ms really dont like bluetooth all that much and their stack lack most bluetooth profiles
maybe the latest vidcomm stack support it
more about bluetooth profiles
http://www.palowireless.com/infotooth/tutorial/profiles.asp
maybe you should look into this product
http://www.bluetake.com/products/BT420EX.htm
but some guy in the forum had one for test and said the phone quality was pretty poor
RE
OK guys!
A short review has been posted here:-
http://www.ppcsg.com/forums/viewtop...t=iphono&sid=6d3d546329a09353b6817f1c28cdca86
From another thread Pocket Bluetooth Tools doesn't work very well with iPHONO bluetooth headphone and the digital Bluespoon bluetooth headset. However, it creates a non-dynamic serial port and enables printing from the O2 XDA II to HP 450CBi bluetooth portable printer.

:roll:
Has there been any new features as far as bluetooth is concerned? any way to file transfer pictures or mp3s with the final rtm leak?
if not will there be any changes?
No. all BT settings are the same. No music in video over BT also.
Mango now has AVRCP 1.3 which is a very nice addition. You can view metadata (title, track, playtime) on compatible devices now.
So my Sony Ericson stereo headset MIGHT display song titles. Nice
Modem teathering would still be nice but I think Mango is going to add support for wifi hotspots now (at least on newer devices) so that should aleaviate my issues there
Are there any solution for unlocked devices?
Bluez development team is getting ready to release version 4.97 with new bluez version that implements AVRCP 1.3 profile. This is very important feature for anyone who uses the phone with any bluetooth enabled car audio system. Unfortunately, ICS doesn't suport it. Can this be integrated into one the custom kernels?

AVRCP 1.3 on BlueZ
During the past weeks I’ve been working again on the BlueZ project and now we can finally announce that the AVRCP 1.3 profile is officially supported.
Technical background
For those who don’t know what I’m talking about, here comes a little background for those buzzwords:
BlueZ is the user-space part of the Bluetooth® technology stack used on Linux and Android. It has support for several Bluetooth profiles such as RFCOMM, HID, PAN, PBAP, OBEX, HFP, A2DP (some of them are implemented as separate projects) that are defined by the Bluetooh SIG. In simpler terms, BlueZ is what allows your Linux device to do amazing things with Bluetooth technology such as stream stereo music, make phone calls and other wireless magics.
One of these profiles supported by BlueZ is AVRCP (Audio/Video Remote Control Profile), which allows two devices to communicate through Bluetooth technology and exchange commands/messages to control the music/video being played.
New features
Until some weeks ago BlueZ only had support for version 1.0 of the AVRCP protocol. This early version allows a Controller device (e.g. a Bluetooth technology-based car kit) to tell the Target device (e.g. a smartphone) to play, pause, go to next music and go to previous music. We’ve now upstreamed an implementation of AVRCP Version 1.3, which adds some nice features to the previously supported version, such as:
Transmitting metadata of the music being played;
Change Application Settings such as Equalizer, Repeat, Shuffle and Scan modes;
Set current status of media playback: playing, stopped, paused, forward-seeking, reverse-seeking.
Some time ago I bought a Bluetooth stereo car kit. How boring it was having the ability to stream music from my phone but not see any information regarding who was playing, which album, etc. This is no more. Now we have proper support for AVRCP 1.3 . Our ProFUSION team utilized the open source baseport for the OMAP™ processor-based Blaze™ mobile development platform from Texas Instruments Incorporated (TI) to help achieve this milestone. Additionally, we worked together with TI on testing and debugging to make this AVRCP 1.3 support a reality. Below you can see yours truly holding a Blaze™ mobile development platform from TI, sending music metadata to a Bluetooth technology-enabled car kit.
Awesome!
This is great news! I am very eager to get this working in my Nexus S.
Any update on this? I would love to see a way to implement this in a rooted phone...
bumpity bump
will he a gooood thing, no other news? bye
Hi!
With a computer and an Airport Express you can for example browse Youtube and get the audio distributed through a hifi system via the outputs on the Airport Express.
I would like to do something similar with an Android based platform. However, I need the stereo channels to be optionally split into a 2.1 or 2.2 setup (speakers + one or two subwoofers). Further, I want the Android unit to be set up as a DSP with cross over and equalizers for each channel.
Does anyone know if something like this has been done before?
What existing platform could be suitable, and what mods would need to be done?
Any software suggestions?
Thanks!
I changed the title.
I need a skilled Android developer to look into this for me.
Hi all
can't remember where I 've read that ASHA ( stands for Android Streaming for hearing Aids ) shld be introduced with Pie Release...
Apple Iphone, since IOS 10 streams audio data to yr hearing aids and they heavily advertise that those are "Made for Iphone..."
Android is ( or was...) supposed to do the same in order to publicly announce "Made for Android" !!!
None of the custom roms I've tried ( RR,lightRom,Cosp ) support this "feature" ??
From what I remember, there was a specific protocol associated with BT Low Energy to provide streaming once yr hearing aids were recognized
Any info welcome
Tested Technology (tested.technology.co.uk) has ASHA up and running with LiNX Quattro hearing aids and a Pixel 3a phone updated to Android 10.
There's currently a very limited combination of hearing aids (just GN's I think, and Cochlear) and phones (Goggle's own Pixels and possibly the odd Samsung flagship) that can use ASHA.
LE Audio, the BT SIG Hearing Aid Working Group tells me, is something completely separate. It's intended to be a much wider application of audio over BLE that will roll out this year with BT 5.2. As I understand it, LE Audio and ASHA use different stacks. The two groups haven't even been in discussion. Don't expect any mutual compatibility.
