I'm looking for a way to redirect my TomTom voice instructions from my MDA Vario through my Parrat CK3300 BT carkit sounding on my car-speakersystem by using the bluetooth stack. Now Parrot claims this isn't possible due to a phone limitation. I agree and think it's shortage of Microsoft WM5. Now I've looked up some info about Bluetooth Audio Distribution and found the following:
Advanced Audio Distribution Profile (A2DP)
AKU 2.0 for Windows Mobile 5.0 (for both, Smartphone and Pocket PC), which is expected to be released early next year (2006), will also includes support for the Bluetooth Advanced Audio Distribution Profile profile which is designed to transfer a stereo audio stream like music from the device to a headset or car radio.
A2DP is already implemented into the Samsung SGH-i300 Windows Mobile 2003 Second Edition Smartphone, however this isn't based on Microsoft's A2DP implementation but Samsung added it itself.
(Refer to http://www.theunwired.net/?itemid=2779 for more info concerning this subject.)
So if this article is based on true facts, it means that Microsoft will soon release a patch for all WM5 based devices, which enables them to receive all audio (e.g. TomTom voice instructions) through the bluetooth stack.
Somebody knows more about this subject and if it's true that after having AKU 2.0 installed, you can hear the navigation instructions through your carkit or headset?
Many thanks,
Youri Festen
there is a facility on this forum that will allow you to switch audio to and from the bluetooth, not high quality or stereo but standard quality.
There is ?
Been loking around in the threads for quite a while, but didn't find a replicatable solution...
Here you go
Tried all kind of files, but no go...
All i want is ALL audio over the Carkit (Supertooth2). That is TomTom + Phone.
I don't care if i have to trun of the carkit to return audio to the phone. But i don't want to have to reset or something.
I have a XDA (Himalaya) btw. Still with Rom 1.72 00WWE 15/03/2004 (Ext Rom 1.72.125)
Tried all these :
BA_OEM_AudioGW.CAB

whoa it worked
i know im reaching here, but really wanted to try to stream to the new cingular 2125 (aka hct). downloaded and ran the app with my iphono steroe headphones (luv em), got intresting results.
it worked. ran the app, pushed the button on the headphones, got music. call came in, answered (with auto answer) talked, and on hangup it went back to music. however, if i ran another app on the phone such as voice tag in contacts to initiate a call, it brought in the call, but on hangup went back to the speaker. had to run the toggle on again to get headphones working, not elegant - always want more - but im a happy guy til a2dp comes out for mobile 5. thanks!

Try reading and understanding what you read before posting. See the post of dalamario that is the BTAudio on/off tool !
Is this goingt to be anter shout and wild guesses about what file or tool should "really"work ?
I tried all so called "easy" fixes, hell, i've even got a whole dump of my registry, cut through all the BT + Audio and BT + Headset threads, here and on PDAPhonehome, Howardsforum, and the reduced-to-user-bla-bla on pocketPC-club.nl.
And still zilch.....
Ow, and don't think i'm someone who wants easy answers... Think again, i've been around quite a while on PPC forums and the lot....
What i do want/like is usefull answers ans clues on how this BT and Audio stuff works, beut even after reading some on MSDN i can't find a solution yet....
That's why i jumped in on this thread, i'm not going to reinvent the wheel if some allready has the solution: Tomtom and Phone audio over BT
So i'll stop writing now, and continiu searschin for a solution... There must be one...
Sorry mr high horse, wont bother trying to help next time just in case i might not be right, but then if everyone did that no one would answer anything.
The Wizard can do system Audio over bluetooth.
This has been proved with the easy hack that allows you to activiate voice dial using a BT headset.
http://forum.xda-developers.com/viewtopic.php?t=29837
MS Voice Command leaves the Audio Gateway open after initialising, whilst Voice Dialler closes it.
So maybe try installing Voice Command and doing the hack in the above referenced thread, and then see if you can launch Voice command from your car kit. This should leve the gateway open and allow all system sounds to stream to your BT kit until you hit the button again.

Try keeping Himalaya talk in the Himalaya forum then. Posting questions about devices in the wrong forums just causes confusion.

Not Mr High Horse, but didn't you look at what you where posting ? You should know it linked to the same file, right ? If not, you really would just be 'shouting' ...
It's just that i've been reading XXX threads, and just about everyone comes up with the same, useless, files... Like nowbody really knows how it works and waht should be done to make Audio over BT possible...
We here are all trying real hard for months now, you see....
Just a little patience. Test version of Qtek 9100 ROM with A2DP already exists. It works with I-Phono bt-stereo, for example. So I think it will be released by March.

have one question whilst here,
when i am on the underground the headset give a beep to tell me i have no network signal? you may not know the answer but would this over ride the bluetooth stereo signal?
p.s. send me your bank details for the transfer :wink:

Do you think that when it works with I-Phono, it will also offer us the navigation voice instructions through BT-headsets or carkits? Hope so!
Can't test it with car navigator.
if audio streaming is enabled, i would have thought you should be able to hear navigation commands.
i have used the bt audio switch that started this thread to hear tomtom commands through my headset, and it works fine.

It's nice.... I'd really like Tomtom over my carkit... Ohh, the XDA was so much easyer just soldered a Ground and Left/Right channnel into my TomTom/Leadtec connector, and plugged it in to my JVC Front-in line...
I bought the Qtec 2020 because BT seemd so much easyer
Hi,
maybe someone can give me some info.
Have a T-Mobile Germany MDA Pro with the newest Stock ROM supporting A2DP.
Have board a brand new Plantronics Pulsar 590A Headset. It works, but the quality of the sound is very very bad with my Universal. I have also tryed the smal A2DP Sender, that comes packed with the Plantronics device and the quality is 100 times better. What is the problem? Can I adjust the bitrate of A2DP transfer in wm 5.0 registry?
The sound is a little much deep and on mid to hig frequencies, i hear a high frequencie noise.
Does anyone else has this problem?
This is not a problem of the receiving device.
Thanks for any help on this :`)
No Ideas?
Please Help!
I have the Qtek WWE ROM on my Qtek (latest official version). I use a Jabra bt620s, and i have no problems with it.
Maybe it's some obstruction of the signal? Do you encounter the problem when the Qtek is in clear view of the headset at a meter away?
I have the Motorola HT820, and finally got round to installing the Qtek WWE ROM today. Connects fine, I can walk into another room from the Uni and have no problems; But -
I also get a high pitched noise, particularly on music with lots of treble. It can be controlled up to a point by tweaking the graphic equaliser, but it is still annoying.
When using the HT820s linked to my Bluetooth PC and laptop, they sound superb - so it is a problem with the universal.
Thanks so far, i start hating my Universal ....
I think, there can be 3 reasons for that.
The Windows Mobile A2DP Software encoder, if it is software encoded.
The Bluetooth Chip, if it is HW encoded in Bluetooth.
The Radio ROM or Chip, if it is encoded on the Radio Processor.
I am not so deep in the Universal Technologie, but i know, that the sound was very clear on Blue Angel using the broadcom stack. So I think, it is M$ Bluetooth that makes the problem, but i am not realy sure.
... or is there anyone how don't has this kind of problem?
Hi,
I personally have never had that problem (which I interperate as "some form of noise" when listening to music over A2DP) you guys mention here, neither with my Motorola HT820's or i-Tech BluePRO's.
Only problems I have had with A2DP and my Universal is;
1. Pause/Resume button not working always in Windows Media Player (works fine in latest version of PocketMusic though)
2. Not automatic reconnect of A2DP when I turn headset on (only prob with the i-Tech's, Motorola's seems to work fine)
3. Occational drop/loss of sound for a second or two (have this under control now, only an issue for me now, when there is to much obstructions between Universal and my i-Tech headset)

This is a general Universal Problem. Maybe Radio Interference, maybe missing some CPU power.
The noisy and unclean sound can be a ROM Version Problem, if you don't have that. I have tryed also with a Linux Computer as A2DP SINK Client, and the sound is same bad.
That's my ROM Version Info:
ROM-Version: 1.30.113 GER

Try downloading the latest PocketMusic version (if free for 30 days I think...so you'll be in heaven for 30 days at least), there it works perfect. ...it was enough for me to "cough up" the money to buy it!
And yes it seems to be every second time, and then one has to press button on Universal/Media Player once...bloody irritating...when the Universal is in the bag or something.

Yepp, I have exactly same behaviour (handsfree no prob, while A2DP needs manual reconnect with iTech's...but with the Motorola HT820's I belive it was automatic though)

For me I am pretty sure it is pure radio problem now (have tested with an app called SuperTask, and A2DP takes approx 20% CPU, and my JasJar now used a total of 40-45% CPU when I listen to music over A2DP with PocketMusic). I only have this problem when I have the JasJar in my pant pockets, are in an area I know there is a lot of interference+have some obstructions. Except from that it is fine now.
You can see this post on my "socalled test" (it was just a simple test, but it seems to give a good indication at least) of A2DP's effect on CPU here;

I have no clue...do you have a Universal (I would guess so from that you post it here )...if so the HW is identical...so then...yes it should be the SW/ROM...since you actually have tried with another "headset" (your Linux computer). But I am sorry, that I am not much of contribution...if nothing else...I agree with your logic here!
BTW my ROM version++ is stated in the A2DP-test post I linked to above (don't remember the numbers...but I have the "latest QTEK WWE" ROM).
Thanks for your comments.
Maybe it's the T-Mobile Germany ROM that is the Problem. Have allready called the technical support at T-Mobile, to help.
Maybe they are ignoring me, but i have tryed.
Universal's blue tooth signal terrible
Look I had many imate devices and bluetooth sets. The Universal has a very weak bluetooth signal even with normal bluetooths.
I have tried 3 or 4 different bluetooth headsets and they all give me a max of 3 meters. With the Jam and pda2k with the same headsets I used to get 10meters.
I gues this is the reall problem you are facing, the bluetooth reception is terrible on Universal, try being really close like 40CM away and if the sound is good you will know that it is only a reception issue from the universal.
I noted the 40 ~50 cm distance problem when I reviewed my nokia hs-12w a2dp headset about a month ago, it is very irritating. I think it is to do with where the BT chip is placed !!! it is between the keyboard and the battery, from what I could tell of the exploded diagram on this site !! meaning it is surrounded by metal !!! not good .
PS I never have problems connecting my hs12w headset for audio use, however if I take a phone call, after the call has ended I loose AVRCP

Hi cr2,
yes I read about it in IRC Log. But what you like to do is, streaming sound direct to the bluetooth hardware. Universal hardware supports this feature. There are 2 Bluetooth Profiles implemented for, one is called "Handsfree" and one is calles "Headset" and ini Windows Mobile Registry you will find it if you look for "Audio Gateway". The registry values are also documented in the online MSDN Lib. I will post a link, later, if I find it.
What I am doing is A2DP, that means ... all stereo sound will be compressed in software and then send as datastream to the bluetooth device.
Have attached the A2DP specification. Under Linux there is a project calles "bluetooth-alsa", that supports A2DP and Handsfree. Look for it at sourceforge.net.

There are several options here. It can be sent directly
on some phones, or (theoretically) through the phone,
or even redigitized from the analog (for mono).

Software is not a problem. We need to understand
what the hardware is doing.
Guess I must be missing something, but I can't see what all the A2DP dramas are about.
I have a new Jasjam and BlueAnt X5 stereo bluetooth headset and I got the skiping problem the first time I tried it. I soon discovered switching off WiFi completely fixed this and then I read about the reg hack to get stereo working.
Now my setup works perfectly.
Is there something wrong with me?
No, join the club. Worked right out of the box for me too.

"Completely"? How? Just keep it off in Connection Manager? Or something else/more? I've never used WiFi on my JASJAM and I still have skipping, even with the WIDCOMM stack.
Its all headset based. I'll add the ?BlueAnt X5 to the rather short list that works out of the box. The other ones I know of are the Nokia HS012W and the I-tech clips.

I can also confirm that the Nokia HS-12W works right out of the box.

I don't have any problems with my I-Tech R35, but there are reports from other people who do. I always try to keep the number of simultaneous tasks down to a minimum, and close apps as I go along. Being tidy, and not loading the device, I intuitively believe helps reduce problems.
I don't think it's quite as simple as just being a headset problem, although it's certainly a contributory factor (another is definitely the distance - inversely proportional to distance squared - the headset unit is from the phone unit when using a2dp over bluetooth).
A2DP is not working well.. when i use ad2p headset the audio fails VERY Much. If i turn off A2DP wmp plays well the music.
Is there any patch?
Thank's!

I found this patch! It's not 100% good (sound fails ONLY time to time and drains battery ), but is almost, i think that with some work could get there...

Use a registry editor and add the following to your BA registry:
HKLM/Software/Microsoft/Bluetooth/Devices
Add a new DWord: DefaultMTU with the Hex value of 2a0
Capitalization counts in te DWord.
BTW, I posted this 2 days ago in this same forum under the "muppet" thread. Search is your friend.
Thanks ^^ ill try it when i get home.. forgot my bt620s today >.>
Geh i did search ^^ but i never figured the Muppets would have anything to do with ad2p *grins* So many random topics in this forum it feels like searching for a needle in a haystack
No devices under bluetooth, only device.. and under bluetooth/ad2p there is a map devices.. under device and ad2p/devices it didnt do the trick
wait wait.. hard reset.. and it worked.. now to see where it helped.. i stuck the key in 3 places.. lol
Jup just another soft reset killed it again (without removing one of the keys).. seems my ad2p only works right after a hard reset.. and then dies again.. no matter what fix..
Nother funny thing, before adding my bt headset it sees my laptop bluetooth.. after connecting the headset it sees no devices..
HmHm.. going to flash pdaviet on it in a sec radiorom 1.15.. try that.. maibe try the helmi's broadcom bluetooth stack..
My solution with pdaviet and radio 1.15 ^^ connect the wireless stereo.. startup mediaplayer and listen how sucky it sounds..
hit pauze.. turn off bluetooth.. turn on bluetooth.. go back to the mediaplayer and make sure it listens to your bluetooth headset.. (play and pause if it the mediaplayer responds its OK ^^) And then turn on wireless stereo again.. its a hassle after every softreset.. but hey.. it works ^^

for some reason this KB article is only in Japanese but google translates it well. This is where I got my information and I can tell you I never have the difficulties yoiu are describing. Try the following steps and let me know if it working:
1. Connect the headset
2. open the media player of choice
3. start playback
4. pause playback
5. wait a couple seconds
6. resume playback
at this point it should play without any pauses/skips (works fine for me, but my BT range blows so bad, and my S9 headset is so uncomfortable I hardly ever use it. (If anyone wants to buy a nearly new S9 heatset let me know)
BTW It seems to be a known issue with BA + WM6 that headset disables all other BT connections. I would love to be able to use my GPS and headset together, but alas it disconnects the GPS everytime the headset is connected. Drop the headset and the GPS reconnects immediately.
One final note. All my testing has been done with the MS BT Stack. I read that Widcomm has no hands free support so I didn't try it.
Helmi's Broadcom Bluetooth Stack 1.7
I could never get the MS BT Stack to work right. Helmi made this test cab. It works well with my BA using WM6 and my Motorola S9 headset. The range is about 1 meter but the sound is good.
The BT manager format is accessed through the BT icon on the bottom toolbar.
I cannot upload the .cab file. Search for this file: HELMI_BA_WM5_BT1.7_TEST for great quality BT on BA WM6.
One way to solve the BTA2DP problem & it supports stereo. You can find these by the following link http://www.teksoftco.com/index.php?section=freeware & this software works too http://www.trianglepowers.com/PPC/ViewApp.aspx?ID=52 (have to register to download). I prefer Teksoft freeware as I am using it. Sometimes it takes a while after a few toggle u get it right
thanks alot trying the teksoft one and so far it works fine ^^ maibe ill see if its possible to skin the buttons tho
@kasush That method doesnt work for my headset, the Jabra BT620 can be a real ***** even on my laptop at times.. so i really need to turn off the wireless stereo.. So gues the S9 isnt that bad apart from the fact its not so comfortable.. the BT620 is great.. when it works ^^ just turning off the bloody blue rings on the headset everytime is anoying *grins* people think ufo's landed when i ride around with those on.
(Lol, just noticed there is a firmware upgrade available for my BT620s :O.. lets see how that works out ^^)
Mogul Widcomm stack
Has anyone successfullly installed the widcomm stack on their mogul. My pioneer Avic D3 hates the Mogul's MS Bluetooth stack. Keep me posted hackers! I love this site btw. I'm it's *****.
There are a lot of problems with carkit connections & the HD2.
I tried several things to get it working without success.
When I try to connect to the JVC KD-AVX44 it connects but give no sound at all. (making 2 connections, handsfree & stereo audio)
Then I tried the registry tweak mentioned into this forum and had success once. I was very happy because also the title track was shown onto the JVC display and also the phone was functioning ok both ways.
The sound trough AD2P was perfect. Only one time.
After that i get a lot of disconnects.
Then I tried to make only connection with the phone function and this is working ok now. When I want to make the connection trough AD2P then the problem is back. Also when you make it without making the phone connection
So I think the problem lies into the stereo connection. For instance when you skip a track onto the JVC then the connection will be lost and reconect again and giving 2 seconds of sound and then it's quiet again.
Also when to 2 connections exists the phone is blocked by incomming calls because it's thinking it's connected so the earpiece & mic are dead at that time. And also the radio.
Did you try the LineSpeed setting to 256 in the AV key of the Widcomm registry settings ?
Don't know if it could help in your case but it did for me, I don't have disconnects with my Sony headphones anymore and sound is better.
Bluetooth
Ok thx I will give it a try and post the results.
which registry tweak did you applied first, cause i too keep having issues...?
tweak
Change Registry setting:
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Sys
Add the DWORD setting COD=5374476
This makes devices see the HD2 as a 'Normal' phone
Do I have to add this line somewhere? I found the AV key into widcomm but the line was not there

Ok i make this in my BMW X5 and one of problems is solved - HD2 working correct when i am on call and power the car, but i have another problem - after 5 - 6 min on call Bluetooth connections is droped and i can't lisen nothing from Car or for Phone - i must to press Menu and switch off Hands free to continue conversation.
Ok but are you also making stereo connection. I only have the handsfree conected at this time and then the connection is stable. Only with the A2DP it goes wrong.

Yes, you have to add the key, sorry not have said that.

Strange, so far I didn't experience any disconnection.
I have conversations during more than 20 minutes daily and line quality is far better than with my Diamond, with no drops.
With the Diamond I had the BT stopping regularily on the phone, it was very annoying because I always discovered it when receiving a call and not being able to answer.
So far it didn't happen on the HD2, but it is really too soon to jump to any conclusion.
I don't use A2DP in the car as I didn't order the option, which I viewed as useless because the hard disk capacity of the iDrive is sufficient to hold a good collection, the audio quality and functionality is much better and I can still connect the phone to the USB plug as mass storage if I want to play or transfer something from it or any memory stick or external HD.
So maybe not having the A2DP profile active may help also.
I also not any problem with my old HTD HD and Cruize ... but with HD2 i have this issue.
Today i receive answer of my ticket from HTC: they offer me to contact with BMW and to ask them why they not support HD2 ... I think this is stupid becouse every new device must support old protocols and older devices.
Now the choice is to change Car or Phone ... sorry but HD2 not have any chance to survive.

Yes how lousy is that
Got the same answer first, but they realised that BMW coudn't recall thousands of vehicles to do a BT upgrade just because HTC decided to adopt the crapy Widcomm BT stack.
So they say they are working on a fix, but given how many issues there are with this stack, they better switch back to the old MS stack instead.
To be clear, it is the Widcomm stack at fault here, not BMW. Every single phone not equipped with this stack, I could try on the BMW, worked flawlesly.
I hope they will recognise this officialy and not blame the others each time a customer opens a ticket about these flaws.
In the meantime, the registry hack works perfectly for handsfree profile, but it seems it doesn't fix everything when the A2DP profile is activated.

After much playing around - I found a linespeed of 300 works best for the HD2. 256 still has questionable quality and 320 for some reason skips a lot. Reducing it to 300 seems to be a workable equilibrium!
