BLUETOOTH STACK - please please help me

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.

UPDATE
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

A2DP quality fixes in new roms...

I've heard about a bunch of new roms (the BLACK and LVSW) that have somehow cleared up that nasty A2DP bug in the Microsoft BT stack that caused certain headsets to buzz and hiss with certain frequencies.
I'm wondering if anyone here knows how that works, what has changed in these new Roms? Are they updated bluetooth drivers from MS?
I'm wondering if we can't put together a new a2dp patch for other devices so that additional phones can benefit as well, without getting a whole new rom (similar to the way the initial Tornado A2DP patch was circulated around).
Anyone have any info?
Can anyone even verify that this is true? (I don't have a hermes, but I do have an i.tech R35 headset with horrible distortion from any windows Mobile device playing music... I'm just assuming what I've heard is true about new roms fixing it...)

The only change is to some registry entries, the HTCustom tool should work on most any phone. Black's config tool should work but sometimes crashes on other roms when you try to save.

I have got the same problem with my iTech. I think it is something related to the design of the bluetooth headset. Is anyone experiencing the same problem with a solution?

nope maybe your release is a bad bath?

My Hermes with the Black ROM works fine with my Jabra BT620s. Hands-free mode works flawlessly too.

No no no, this is KNOWN issue with the MS stack and certain Bluetooth headsets, including the R35.
Its not the headset.
Proof is that when paired with another device, IE a nokia, or PC running bluesoleil, it works just fine- no hissing, very good audio quality.
Also, tested on a Wizard using the Widcomm stack instead of the MS stack, and sure enough it works GREAT!
So, its clearly a problem with the MS Windows Mobile stack, and in fact it has been discussed in various forums here.
Shadowmite, are you sure its just registry changes?
Is there any way to find out what they are?

Correct. I had that problem with my Vodafone V1640 (HTC Universal). Kind of solved that problem using the Widcomm stack patch uploaded by someone here. Go search for it.

Yes, I mentioned that I had it working with the Widcomm stack on a Wizard, but I'd rather have a working MS stack for various reasons including the Widcomm stack's instability on certain devices, and more importantly, its not available on the Tornado and Vox (or any smartphone), which is my device of choice at the moment!
So, once again, does anyone know what these new roms do to "fix" the problem?
Its gotta be something I can re-create...

Sorry, I missed that part.
I didn't notice that Bluetooth performs differently in custom ROMs on the same hardware. If it is true, the ROM creators would know what they have done. Try contacting them directly if no one else here knows.

[HTC 8525 + WM6] Bluetooth keeps disconnecting

Hello!
I do not know if someone has the same issue. I upgraded the WM6 to my HTC 8525 and bluetooth just keeps disconnecting all the time. It happened without any reason at all. I am using "Plantronics 510". The headset is fine, just phone switches the bluetooth off and I need to go to settings to switch it back on. I saw some people have a problem with car-enabled bluetooth. Not sure if it is the same problem.
Any advice? Does someone get the same problem? Any patch or solution?
Thank you!

which WM6 ROM are you using?

I had this problem with my Audi A4 car phone. The ROM versions using build Build 17745.0.2.3 were not good for that. Now, I'm using the Black Majik ROM and that works like a dream for the BT connections.

i started having the same problems but i noticed it after i installed the voice command.. the rom that i use is the gm360 gold. the problem ive got was whenever i was in a phone call using my blutooth and i received a text message it would deactivate my headset. if ur having somewhat of the same problem try disabling ur voice command software...

Multiple AT&T/HTC WM6 ROMs?
My 8525 with the WM6 ROM can no longer route the audio to the BT headset (a Moto HS850 - but this is irrelevant, I suspect).
Basic BT headset usage was fine with WM5 (excepting the known issues with VoiceCommand).
I thought that perhaps the issue was related to the various little registry tweaks and sw patches. However, I had to do a reflash (for other reasons) and currently have just the default WM6, no registry tweaks, no BT sw patches, and MS VoiceCommand 1.6 installed (but set to NOT use the BT headset).
Pairing works fine. So does activation recognition (i.e. the little headset appears in the notification area when I open the boom on the headset and I can hear the background establishment of the BT channel). But audio (dialing tones and Connected call audio) do not reach the headset. The audio also doesn't go to the phone's speaker.
So, are the official ROM updates that repair this? Or, is the cost of going to WM6 the abandonment of BT headsets?
By the way, VoiceCommand 1.6 works fine--if I tell it to stay away from the BT headset.

Pays WM6 Roms
I had the same BT disconnecting problems with my original german Vodafone WM5 and also still have them with Pays WM6 ROMs (2.02 - 2.15) in my Audi A6 MMI.
With the original german HTC WM6 ROM BT worked very well.
Everything else on Pays ROMs is really great. He´s doing great jobs.
Any idea?

I have the same problem with my 8525 and I use plantronics 520. It did the same thing even with other headset too, and also happens in WM5.0, 6.0 and 6.1.
I am tending to believe its a hardware issue, but dont know how to prove it!

Come On, experts on the XDA portal, no solution?? noooo way!!??

My friend had the same issue with an tytn2 and last schap's rom in french language.
After an hard reset i get BT work fine with his OPEL.
But before i made lot of test desinstalling soft check registery key with no result. I still do know why BT was disconecting woth no reason.
Cheers.

Audi Bluetooth hands free
I had the same problems in wm6 with some roms.
I use the official HTC TyTn wm6 with excelents results, also Schaps 4.31 work very good (No disconection at all).
Now I am using Pay WWE 4.30 with many disconections.
BTW I have the audi TT bluetooth option.

On my 8525 Hermes I use the latest Pays Rom and it was disconnecting all the time (Parrot BT) - BUT then I decided to TURN OFF THE WAN and it improved greatly. Other thing I noticed is that the Hermes has to be in DIRECT LINE OF SITE of the BT device at all times or it is erratic.

BT
It seems there are differences in the WM6 versions. As said earlier in this thread for me original HTC and Schaps WM6 ROM versions are running without any BT disconnections.
Tried several WM6.1 versions now and every single one is working fine with my Audi MMI.

Similar problems handing BT control between applications
Hi all, I've been experiencing similar problems since changing ROMs. Originally with Schaps 3.60a I was able to make a call whilst listening to music all using my BT headphones. The Call would pause the music & resume afterward. It worked great! However since changing to Schaps 4.0, 4.2 & now CRC's PHKv12r9, I've never had the same. On a couple of rare occasions it has all worked fine but more often the bluetooth has to be turned off & back on again to reconnect. it seems to relate to what other programs are also running. I suspect there must be registry settings which control the bluetooth operational modes which are brought into play by the various programs running.

Trouble with Wifi and Bluetooth at same time

I've searched around for this and can't find anything, so maybe someone can help to point me in the right direction or let me know that at least the problem is known but not fixed yet.
I can't get Wifi and Bluetooth to work on my 8525 with WM6, currently using Schap's 3.54c rom and radio version 1.48.
I have motorola s805 stereo bluetooth headphones and would like to stream radio over my work's wifi and hear it on my headphones.
The problem is Neither wifi or bluetooth work reliably when used at the same time, (no problems individually). I have even tried reducing the bit pool, but can't take it below 24 because it sounds to bad then, but it still doesn't work.
Anyone have any ideas or can at least verify you have the same problem?

I have the same issue when trying to play internet radio over wifi with my ht820 a2dp linked to the jasjam (Sleuths v2 rom). The only time i ever got a2dp and wifi streaming to work was with the widcomm bt driver that is now extinct.
Thus i have come to the conclusion that the problem is not with the hw but has more to do with the standard ms bt stack.
If anyone has found a workaround please do share

Thats a start
Thanks, that is helpful.
I remember seeing a widcomm stack thread....
http://wiki.xda-developers.com/index.php?pagename=Hermes_Widcomm_stack
I'm going to check that out, also if there is a specific rom that comes with the widcomm stack I'd be interested to know.

I find that with bluetooth turned on I can associate to my Cisco AP at all. As soon as I turn Bluetooth off it works fine.
I had hoped my issue was due to the way the particular WM6 was put together but now Im using offical Dopod and it is the same.

Widcomm stack
Well I found this
http://www.htc-devs.com/uploads/Univ...m_bt_stack.CAB
at the end of the Widcomm stack for Hermes development thread.
I'm not sure where it came from, but I installed it and so far I can use IE while connected to my home wireless network, and listen to music on my headphones.
The com manager will not show bluetooth as being on, but go to settings-bluetooth and you can re-pair.
Currently I'm getting some hiccups, but its working at least. I'll keep you updated and I would still like to see a rom that incorporates this stack so that the com manager works right.
It also changes the headset icon on the top bar.

Streaming!
I'm streaming SomaFM with no problems!

AVRCP problems
I didn't notice this at first, but after the widcomm stack has been installed the AVRCP functions don't work... so Im going back.

AVRCP
It works in WMP, just not audiomanager anymore.

Bricking Blog
Pretty much what this thread has turned into.
If you install that cab above, don't uninstall it, you'll get bricked.

XDA III connection Motorola S9 BT Stereo Headset

Hi all,
i had bought me a Motorola S9 Stereo BT Headset, that was working great with my Nokia N73 for calling and listening music.
But my XDA III (Blue Angel, Qtek 9090) doesnt support music streaming. Only calling. Is there a way to solve this problem?
regards
Serce

/push
in the meantime i found out, that the device must support A2DP. The Blue Angel didnt support that, but is there a new firmware avalaible with this function?

i have solved that problem by myself... just installed the cabs from this link:

Wich operating system do you use? WM2003 or WM5 or WM6?
I still use (an prefer) WM2003 (with the 1.0.0.3900 BT version) and don't know, if the linked cab is compatible to my device.

i use wm2003 and works fine
