I have read every post about MS bluetooth stack vs widcomm etc....
I know someone can build a cab file that will uninstall the MS one and replace with the newest widcomm stack.
I LOVE my universal but I carry TWO phones with me because the universal's connection via bluetooth is not PERFECT for phone calls like the blackberry (oh i fking hate the blackberry for everything else).
I REALLY REALLY REALLY want to use only my Universal but the static on bluetooth KILLS me because I am on the phone 10 hours a day.
PLEASE please help me. Fish
This file fix Blue Tooth
Bluetooth stack
I would second Fish's comments about the Univerasl and the Bluetooth stack. I have bluetooth in my car and it is great WHEN it works. When it doesn't work it takes a lot of tinkering to get the car to recognize the phone again. I'm of course not sure if the issue is on the Universal side, but Bluetooth turns it self off, so there is some kind of problem. I have tried different radios, currently 1.13 (tried 1.14 as well, but went back). I'm very interested in finding a solution (not using two phones), can you please provide some detail on what the CAB file does to Bluetooth?
Thanks,
Sven

What exactly does this file fix/change ?
I've just installed the WM6 crossbow helmi_c version
do I still need this file ?
This is a Stack changer to change from MS BT stack to Cambridge Silicon Radio BT stack. Originally developed for Dell AXIM (about what I've found). Seems to work fine there, but need to uninstall/reinstall after every soft-reset because of a volume lock bug.

Do not install this patch yet. It is over a year old.
Follow the development/information on Widcomm BT Stack instead. Following links

I'd rather go with the widecomm BT
I installed the Hermes Widcomm BT stack on my Universal. Sound is great, but the rest is troublesome. We need a developer to fix the code for us so it works on the UNiversal .
Check my thread in UNiversal/accessories. Or move that thread over here please!

Tried out BT Stack change for Hermes patch/program.
TEST RESULTS ON UNIVERSAL WITH WM6 (Midget aka Helmi unreleased)
Sound IS great. But other than that, this program does not work very well on my device. Of course this is designed for Hermes but I gave it a shot.
Issues:
1:
Screen flickers (only when this BT is turned on).
Flickers really bad and unable to use device.
Fix: set the device to standby (power button) and wake it up again. Flickering gone
2:
Once BT is deactivated for a few minutes I can't start it again.
Fix: No fix found yet. Only a Soft-reset and directly activate BT works.
3:
I can't use my GSM/UMTS connection anymore. Trying endlessly. Even after soft-reset's I can't connect. WiFi works fine though.
Fix: No fix found yet.
4:
Unable to uninstall this program. Tried several times. I get to the "Soft Reset Device Yes/Cancel". I soft reset, program still there and working.
5:
Hard-Reset, complete setup with WAP, MMS, MAIL etc.
Installed Widcomm BT Stack again.
Soft-reset:
Screen flickering (fix)
No 3G/UMTS connection avalible anymore. Even when BT stack is completly shut down.
We need a specific one for our Universal. Who's up to fixing this for us?
KEEPING this post updated.

Quoted from my A2DP/AVRCP thread in accessories.
Even with the new WM6 roms - I have tried ALLLLLLLLLL of them the bluetooth phone quality sucks.
I am using the new Pdaviet 2.0.03 (something like that) and i have tried
THREE different headsets
Jabra BT250v
Jabra BT500
Jabra BT500v
All have the same crackly sound issue. But with my blackberry (ass phone, i HATE it) the sound is PERFECT.
I am soooooooooooooooooooooooooooooooooooooo tired of carrying two phones with me - i can not live without my memory (or i mean the universal, which i use as my personal assistant). But my clients can not live with the quality of the phone call connection. Now if I do not use my bluetooth and hold the GIANT universal up to my head (kinda like a military field radio) then the clarity of the call is great.
It is the Bluetooth stack i am 100% sure of it.
OMG Helmi_c let me have your widcomm stack PLEASE I will even pay you for it.

Thanks for the info
I changed the channel in the registry of the device to channel 5 as suggested on that webpage. It was the same quality. I then tried a few other channels and the same results - connection quality still staticy.
Thank you very much for trying to help me though. Fish

I'm also worried with the same issue, because I've exactly the same problem. But I don't think only altering of BT stack should fix the problem. My understanding is, something is also to be done in radio (rom) side itself. Because I was using a different radio rom last year at about May or June and my BT headset worked perfect. But I can't remember now about what build that was, because later on I've updated my radio to few other releases.
Radio rom has NOTHING to do with the Bluetooth or Wifi - It's ONLY the firmware for the GSM chip.

We know the MS BT stack is crappy. I found out today that Helmi_c is developing one. But, still, this thread should be more about how to resolve the BT stack change (or just shut it until our friend Helmi_c finishes his school stuff and gets back to being the ROM-N3rd in need of more RAM that we all love so much) than bringing up more issues about the MS BT stack.
Thanks.
guys,tried almost all roms on my universal,some of them works a few days,after 3 months i flashed with the good old official rom,better and stable than all
anyway,the only reason for this waste of time was this a2dp issue,being not able to listen music to my motorokr(tested with 2 laptops and 2 htc,working great)
so i think is just some kind of incompatibility motorokr-universal(yes,i try all the a2dp hacks/registry editing found here
So I owned my BA since 2005 and tried all ROM/radio/BT upgrades and now am at xplode's ROM and 1.15 radio and 1.39 BT, still can't keep BA farther than a foot away from my headset. Static just kills any conversation on the street. I come to think it's the hardware, and as such, it's unfixable. This is so far the reason that I don't use my BA as a phone anymore -- I'd rather keep it in sync with my Mac, and also sync up my Nokia, via Missing Sync. If I happen to have a contact I need on the Nokia, I can beam it from the BA via BT. Of course, SMS is the main reason to prefer BA, but I'd rather have a solid headset connectivity. I also didn't like it under WM2003SE when the phone had to be rebooted during a call. Overall, I'm afraid, we'll just have to move on to WM Phones with more solid BT headset connections, or -- better yet -- to iPhone.

BTONBASUCKSABIGONEANDTHEREISNOFIX.
Ok, so I finally got into the smartphone game to get a better music streaming experience. MFRadio and MFScorn just weren't cutting it for me anymore. I hated the skips and the ridiculously long (and repeated) buffering time. So I first looked at Android phones but went with WinMo because they say you can run both OS's with WinMo (and the only Android offering from AT&T has a 12-hour standby time before the battery dies, according to reviews).
I have a Bluetooth head unit and have had over a dozen phones paired with it. This phone however is a completely different story. I have installed the latest "release" from AT&T (from a thread on this site). At first I tried streaming with the bundled Windows Media Player which apparently doesn't stream anything at all (with both the bundled and downloaded releases of the OS), then downloaded TCPMP. TCPMP is everything I have ever dreamed of in a streaming media player, but the only problem I have with it is that it won't connect to a stream unless I have already opened up a browser window and went to a website. Not the end of the world.
So, I get in my truck and initiate pairing to the phone. It sees the head unit as a Hands-free and as Stereo Audio. I can get it to connect for a split second and then it dies. I get a popup notification that tells me that the phone cannot control volume when paired to the bluetooth device and audio must be adjusted from the device itself. Fine. But then it doesn't work at all. At first, I wanted to blame TCPMP until I realized that nothing at all was working with the head unit. I think I got it to work once but it never worked again.
So is there any way to fix this problem? This is the one thing I wanted working on my new phone. Yes, the notifications that my texts were successfully sent are very annoying (as well as the other notifications), and yes, Windows Media Player for Mobile is useless, but the fact that I can't stream Bluetooth audio on this phone really makes this phone worthless to me. Didn't anyone bother testing this stuff before releasing this garbage? The Tilt is a paperweight to me right now because it can't do the one thing I want it to do the most. I might as well go back to my Sony Ericsson W760a at this point!
What can I do? I have not yet unlocked anything (although I have a SIM unlock code waiting) and have not yet flashed Hard-SPL. My phone has Bluetooth for Windows Mobile Version 1.9.2 Build 600 HCI Version 4.84. I'd do anything at this point to get this working. Windows Mobile is not that precious to me either. PLEASE HELP!

Hmmmm .... I don't believe you ever stated what type of headset you are trying to get working here? I find your problem to be very strange, even though WinMo does seem to be lacking in a lot of different areas, audio streaming via bluetooth stereo headset is definitely not a problem I have encountered. It even streams flawlessly through my 5.1 hooked to my pc via a crappy 8 buck bt dongle and still sounds excellent. Have you considered that the problem may lie with your bt headset itself?
Also, when you say that you installed latest "release" from AT&T (from a thread on this site), what exactly do you mean? I am running the "unofficial" leaked rom from AT&T on mine and I just paired my Motorola S9 stereo headset and it is playing great for me. You also may want to try using some different software, give S2P (Slide 2 Play) a try and see if you have different results. That's what I am using right now, but I have used TCPMP to play a few xVids through my headset and have had no problems.
The problem is not in the head unit. 25 other phones can't all be wrong. I have no problem using my bluetooth headset. That is probably why you don't see the problem. Anything more complex than a headset will not work with this release. The problem lies within the phone as soon as it displays a notification (which, of course I cannot disable) which reads, "The connected Bluetooth headset does not support volume adjustment from the device. Adjust volume on the headset itself."
That message is the kiss of death. So basically any Bluetooth head unit will not work with this phone? Sounds like shoddy programming to me. Yes, I am using the "leaked" release. I really don't think this release will ever see the light of day. Its horrible! You cannot disable notifications (I don't need to know when my text messages were sent successfully), and it looks like whenever I get a system notification, any program I am using crashes immediately. Like I said before, as soon as I get a notification, I lose the Bluetooth connection (which is like a split second before the notification comes up). I highly doubt this "leaked" copy will ever see the light of day, officially (unless AT&T and HTC do absolutely zero testing on it).
A little clarification for those who don't know... when I say "head unit" I'm talking about a Bluetooth-enabled car stereo and when I say "headset" I mean a Bluetooth headset
My Tilt 2 works absolutely fine with all my BT devices, including 2 Motorola headphone sets and my Sony Xplod head unit in my truck.

I was mis-understanding you about the head unit, I did think you were talking about a headset. Sorry bout that, my Mustang doesn't have built-in BT so I have to use a Motorokr t505 for those chores. It works well but it does give me the same message that you are getting about "volume can't be cotrolled etc" but I can dismiss it and carry on without any problems.
but the fact that I can't stream Bluetooth audio on this phone really makes this phone worthless to me. Didn't anyone bother testing this stuff before releasing this garbage?

Since you don't need your phone for calls, just get Sirius or XM. Ya know, considering you only stream music through the phone..
Did you try the BT headset or head unit with the original stock ROM before you flashed the "leaked official" ROM?
Seems like you might have a couple random issues, with the BT issues and the system notifications crashing programs. I haven't flashed the leaked ROM, but I do know that many random issues with cooked ROMs can often be cleared up by running Task29, which completely wipes the phone memory before you flash a new ROM. I think you will need to HardSPL before you run Task29. Might be worth a try, sometimes fragments of the old ROM interfere with the new one, and cause some bugs.
Bluetooth protocols can be implemented differently by different manufacturers.
I know of many people including myself who have NO PROBLEM with the tilt 2 and different Bluetooth products INCLUDING car radios.
I am using the "new" AT&T ROM and have no difficulties.
Clearly your pissed but your subject is wrong. I would suggest changing to "Worthless as $HIT to ME"
I think my problem is that I am getting notifications which seem to be killing my connection. Is there a way to turn all notifications OFF? The only ones I care about are missed calls, incoming SMS and maybe a birthday. I would like to try to kill the notifications first because I think this may solve my problem
You can get yourself a free reg editor (like Total Commander) and apply the following tweaks to modify the notifications:
SMS sent notification: http://www.mydigitallife.info/2008/06/24/enable-or-disable-the-sms-text-message-sent-notification-bubble/
Other notifications: http://www.mydigitallife.info/2008/06/24/tweak-and-configure-how-notifications-work-in-windows-mobile-notifications/
Although, this sounds like a band-aid just hiding a deeper problem. What you are describing is not typical behavior, and this is something else going on.

For the record my head unit is a JVC KD-BT11 and I have never had any kind of problem pairing any other phone
Somebody else just posted a very similar issue, and found the app hAndyUtils to be helpful:
http://forum.xda-developers.com/showthread.php?t=741311
I think hAndyUtils might just be a app-based way to make the reg edits I posted earlier. But give it a try.
I scanned through the topic and did not see anyone mention this so I thought I would add my .02. The Tilt 2 is different than many other WM phones when it comes to bluetooth as it contains the Widcomm BT stack instead of the MS stack. (Just as an aside, on all my past phones, there were people bemoaning the the fact that it had MS, and trying to replace it with the Widcomm, so I am getting a real chuckle out of folks complaining about the Widcomm and wishing for MS )
In any case, the utilities (Blue music toggle etc...) that used to work for me to toggle between streaming in stereo and plain phone qulity no longer work. However, all my stereo headsets (I own three different brands/pairs) all work perfectly with the Tilt 2. And stay connected and streaming all day.
By the way, coming on a forum that is full of people helping each other and using profanity, anger and threats, is not the most conducive way to get your questions answered. The odds are that the problem you are having is already solved somewhere among the 6+ million posts in this forum. I do not know where or I would post it for you, but it is probably out there. Good luck. And if you find it, please post the link to the answer back here so that other serchers will find it too.
maybe it can come from the phone itself
i had a rhodium for almost a year and never got my motorola headset ht820 to work well enough for me to use it... (more skips than music...cant move my head without a skip)
i flashed to a NRG rom before trying my headset...i tried eveything as far as ref setting, different radios...even flashed my ht820...
no improvement...
then my phone fell in water not so long ago...got another rhodium same model (european)...and it worked perfect out the box on stock rom i can go in a different room than my device and still hear music with no skips...and it still does with nrg rom and latest radio...
so my guess is maybe some actual devices have bad bluetooth hardware ???
I have the Motorola S9 and the HT820 and both work absolutely fine on my Tilt 2.

Can I change my Bluetooth stack to MS? I have installed Hard-SPL and have experimented with cooked ROMs to no avail.
I sent the phone back to AT&T, went to Trinidad & Tobago for a few weeks and came home to a new Tilt 2 waiting at my doorstep (which could have been stolen by anyone!) and I am still having the same problem. So I guess I sent back a perfectly good phone!
I would love to try some different Bluetooth stacks if possible. Where do I go from here?

Did you ever try the solution in this thread? It fixed a lot of issues people were having with bluetooth car kits. Maybe it will work for you: http://forum.xda-developers.com/showthread.php?t=591322
The solution source is here: http://www.everythingwm.com/forum/moto-q-9c/q9c-and-infiniti-g35x-bluetooth-problem-16833-4.html
And here is the solution. You need a registry editor to do this:
1. Modify the HandsFree plug-in:
HKLM\Software\WIDCOMM\Plugin\HandsFree
i. Change SupportedFeatures to 45 (default is 1135)
ii. Add value HFBDA binary, set to same value as LastConnectedBda
iii. Add value HFDeviceType decimal 2
2. Modify the WIDCOMM bluetooth general settings:
HKLM\Software\WIDCOMM\BtConfig\General
i. Change bdaddr to (no value)
ii. Change (or add if not there) DisableReopenAudio to 0 (default is 1)
3. Reboot device
You may also want to do the A2DP quality registry edit: Add a DWORD value of LineSpeed to HKLM\Software\WIDCOMM\Plugin\AV\ with a value of 320.
Give it a try, it may work for you.
I will give this a try and report back. Thank you very much for the response!
No luck. And my bdaddr keeps resetting to a binary value when I reset the phone
My girlfriend and I both have HTC Desires (one unbranded and one Vodafone). We recently got a 2005 BMW 5 series with the I-Drive Pro Nav system in it.
When I try to use BT to connect to the car, I can manage to pair them, but when the phone goes to connect to the car, it only connects for a few seconds and then disconnects. It then connects again and the whole thing repeats. The disconnect is frequent enough (every few seconds) to render the whole thing unusable. It also means that it isn't connected long enough to transfer the phone book.
Both our Desire's have this problem (they have different firmwares). I thought that maybe it was the car, but I put my SIM into my old Xperia X1 and it worked flawlessly with the car.
Is there a setting on the phone that needs adjusting or is it a firmware problem? I hear other people with the same car having no problems with the Desire. I've also used my Desire in a Toyota Avensis and a Vauxhall Insignia with no problems.
Any advice would be gratefully received.

Hi,
I know there are some issues when it comes to Bluetooth and Android, and especially car kits.
Ref (sound quality): http://code.google.com/p/android/issues/detail?id=9888
Ref (disconnections): http://code.google.com/p/android/issues/detail?id=5452
This is supposed to be a fix (I did not get it to work properly): http://forum.xda-developers.com/showthread.php?t=731626
I know that Cyanogenmod has made some changes to their kernel in 6.1 that adresses audio quality (bitpool increased), and I also think that the disconnection is adressed. I'm actually testing it for the moment (6.1RC2).
Thanks very much for your reply - very useful. The link to disconnections that you gave shows someone else with the same car as us (slightly different model) with the same issue.
It's very strange as there are people reporting no problems at all with that car/phone combination.
Unfortunately, I can't try the suggested fix as I don't want to start mucking around with my ROM.
I have a problem with my Volvo and the Desire. No disconnections, but I can't get into the phonebook, using PBAP.
Flashing a MIUI Rom works charming for the bluetooth connectivity, however I'm missing my SenseUI.
Just hoping, praying, some def will include the AOSP bluetoothstack in a SenseUI-Rom
BMW Software update
Hi
I´d try contacting your local BMW workshop, to let them do a reading on your car to establish which software version your car have.
If it´s a rather old software version your car have, I´d suggest that you have it updated.
The software update might be the answer to your problems, and can also explain why other users with the same car don´t have this issue (they might have a newer software version than you).
Remember, this phone is way newer than the car, and also the software in it.
I´d give it a try
PS: Be advised. Updating from very old software to new software might cause "in car-hardware" compatibility issues, and demand new hardware in the car (computer modules ect.), so make sure you talk over which consequences the update could have for your specific car before the update is carried out
Cheers

Thanks for that advice. I'll talk to the dealership and see about software upgrades. Fingers crossed!
I have a 2008 530i and my Desire (and my other halfs) work fine, so hopefully there is some newer firmware for yours. They facelifted the cars and slightly changed the iDrive in 2007 though so fingers crossed there is an update that fixes the pre-LCI models with a Desire.
Just for reference, this is sorted out now.
My I-Drive actually broke and I had a whole new unit put in (under warranty thankfully!). Since they were doing that, I begged them for the latest software, not just for the Bluetooth module, but for the system as a whole.
Since the software upgrade, the phone stays connected and everything works great.
The only fly in the ointment is that it seems that for some reason, not all numbers of contacts (or all contacts) make it into the car's phone book (most of them do).
Anyway, for anyone else having this issue, get BMW to upgrade your BT software (or the whole system if you're brave).
I have similar problem when i try to pair the phone with volkswagen tiguan 2010, it says "your phone in not supported"
I'm thinking of upgrading to this phone, one of the main reasons is that my current device, which has galaxy S guts, is not compatible with most bluetooth devices. I like to use an app called blueputdroid that turns my phone into a universal keyboard as well as an ELM bluetooth device that turns my phone into a dyno along with the torque app for my car.
For some reason the way samsung built the bluetooth makes it not work with a lot of these things, I know it's not the apps or 3rd party devices as I use my old G1 now for it, but would much rather just have my main phone be my one device.
Have any of you tested blueputdroid or any bluetooth devices? If not could someone try out blueputdroid with this phone (it's free in the market) any help would be much appreciated thanx!!
Says it has detected unsupported Bluetooth stack.. Install cyanogen Rom, etc.
Thanks, at least this phone is likely to get cyanogenmod support which will fix the problem my SK sure as hell won't
My GS2 works perfect with my ELM adapter. It worked perfect with my Vibrant too. I've never had a single problem with any bluetooth device on either of them.
I've had a lot of bluetooth problems with both my vibrant and now my GS2. Both work reliably with my wife's mini cooper bluetooth but they both have had problems connecting to the garmin nuvi I use for handsfree in my car (and forget about the A2DP on it).
I tried a lot of roms on my vibrant (incl stock) and they did lots of cool stuff but never made the BT connect reliably. Then I came across this thread: http://forum.xda-developers.com/showthread.php?t=795691
I made the suggested change to /system/etc/bluetooth/audio.conf and voila! I finally have good BT with my vibrant.
So I got my SG2 last week, rooted it and found that it also had the bad settings in /system/etc/bluetooth/audio.conf. However it also lacked BLN (backlight notification) and few other tweaks I've come to love on my vibrant so I flashed juggernaut 2.6. That fixed all the major foibles with the SG2 but it still won't reliably connect to my garmin.
I opened up the filesystem to find that /system/etc/bluetooth/audio.conf is no longer there! Does anyone know where it went?
Apparently I don't have enough posts to ask in the dev forum where juggernaut was posted http://forum.xda-developers.com/showthread.php?t=1322642 so I'm hoping someone will see this plee for help.
thanks
the phone has BT 3.0, but it is backward compatible with BT 2.0 and 1.0 devices
i haven't had any trouble using it with my car deck (streaming audio & phone), my large collection of stereo BT devices, and other BT enabled phones & PCs/Laptops
the remote control feature from the stereo headsets works properly, for fast forward, backward, play, pause, talk, mute, etc
the only thing i have yet need to test BT on is with a BT smart wrist watch
