BT syncing + surfing + BT headset connections WOW it works!

Just wanted to mention that I am now sync'ing and surfing with a BT dongle on my desktop computer over my iMATE. It works great with no problems holding connections and battery usage looks to be pretty good as is the speed and stabilty.
It also handles MORE than one BT connection at a time as I was able to call my iMATE and have that called transfered to my BT headset AND maintain the BT connection with my desktop computer all at the same time without loosing any connections ...

You say to are "now" syncing up etc.. does that mean it wasn't working before? are you using the Widcomm stack or the MS Stack?

@blinky99
Hi it works for you the GPS and headset?

MS BT stack + pairring problem with carkit

Hello,
Bt MS stack is apparently not compatible with all BT headset, hands free en car kit devices. I have been trying to pair my pocketphone pda with a pioneer car kit without a successful result, the image of the hands free appears on the BT manager ‘as pioneer BT unit’, but the standard pin code 0000 or 1111 is always rejected.
Pioneer technical service couldn’t help, they say normally it should work with almost all BT headset devices and a compatibility list of the product is not available.
I guess the problem lays on the BT package. Is there a way to solve this issue by creating for example a BT compatibility patch, or changing something in the registry to make it compatible. Widcomm stack is better en compatible than the MS stack according to many users. Does anybody have any clue?
My device is upgraded to WM6 with always the same sad result.
Thanks

Hi, I have a pioneer bluetooth stereo in my car too, Found it a bit difficult to get paired at first, but it eventually worked. Although it would not give me the hands free profile, only the headset profile, which means I have to initiate and anwer the calls from the phone :-(
thinking about looking at the widcomm stack if I can get it running on WM6

For your information, I have tried the widcomm om my device ‘the last version’, but when I click on the bt icon in today screen, the blue led start flashing for a while but stops with “ memory storage error” . There are some bugs which should be corrected or some registry hack to get it work. However, the widcomm is far much better and stable than the MS BT stack ‘this later sucks’.
Apparently, you have a built-in bt unit, I have a pioneer 6800 + BT unit device optional, it worked perfectly with my old qtek 9090 as a hands-free and an BT audio device without any problem.

A2DP Issues

Hi all,
Laurentius and I are looking at resolving the current issues with A2DP (Many fixes will be in our latest rom, however issues vary from headset to headset.
Some work fine, others are poor quality and some receive PDA lockups or long pauses between streams.
Please could those with A2DP issues, and the need for this protocol to work properly, post the following information.
The current Rom you are you using
The make and Model of your headset
A list of issues you are currently having with A2DP.
Please also try the following to resolve the issue.......
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings\
Remove (Delete the following entries)
BitPool
MaxBitpool
and add the following
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\AudioGateway]
"Capability"=dword:0000003C
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"SampleRate"=dword:0000BB80
"UseJointStereo"=dword:00000001
Please then remove (un-pair) your headset and Soft Reset
After SR please re-pair Headset and test A2DP again.
Please keep this thread clean and only post A2DP issues with the required information listed above.
Thanks,
Cheers,
Beast

Hi Beast,
Isn't:
"UseJointStereo"=dword:00000000
to get proper stereo sounnd?

I have latest V1 rom from Lt.Cmdr.Ivan - BT headset is Philips SHB7102 (works great with my Wizard and SEk800i). I did exacetely what U have asked for (but i have left jointstereo=0) and nothing happend. It sounds like 2s of music folowed by 15s of silence, then again 2s of music and 15s of silence. I messed with bitpool walues and couldn't find any working set. I'm afraid that's something wrong with max BT speed and not with A2DP implementation. I had BT speed switch app when I used broadcom BT stack and A2DP works great. Unfotunatelly normal mono BT headset doesnt work at all with this BT stack so I'm back to original stack

I've found that with MS stack and my Jabra BT620s the best bitpool is 33... good quality and good range (no interruptions)... jointstereo must be 1 otherwise the sound uses too bandwidth...

I also have Ivan's V1 Rom and have an Itech Radio headset. I completed the changes that you suggested and found that A2DP works well it did before the changes too. I have noticed that the sound quality may be a little better and the pauses are slightly reduced.
The main problem I have found with A2DP with all AKU0.5 ROMS is the pairing of the headset. If you soft reset you phone while the headset is on, A2DP will be auto detected when the phone comes up. If you play music then the music starts and stops and the phone becomes unstable. The work around is to turn your headset off, soft reset the phone. When the phone comes up turn the headset on and activate A2dp by pressing the button on the phone. Music then plays fine.
The registry changes you suggested did not help the above problem. AKU0.5 ROMS all seem to have this A2DP autodetect error on reset at least with my headset. Very frustrating.

Hi Maniware,
Can you please further shed light in detail on the jointstereo?
Why jointstereo to be 1 or 0?
Thanks in advance!
KOR!

It goes well with joint stereo. Seems that it needs much less bandwidth. I've heard that jointstero=1 means that there is mono sound in effect.

"UseJointStereo"=dword:00000001 << mono
"UseJointStereo"=dword:00000002 << joint stereo
"UseJointStereo"=dword:00000000 << stereo
AFAIK

qtek 9000 - Logitech Mobile Bluetooth Headset
I'm not quite sure if my problem is right here - because i still have the original (last build) WM5 ROM (130.96 GER, Radio 1.09.00, ExtROM 1.30.185 GER).
I encounter statics while using the Logitech bluetooth headset, which is a mono one, making phone calls impossible due to stressed phone partners ... Only the person on the other end of the line encounters interruptions, me, as calling, not.
This is the main issue for me to update the ROM, and I'm trying to find out if any of your nice new ROMs will be of help.
Anyway, I haven't tried yet I'm afraid to destroy my device ...
thanx
Anna

my feedback:
device:
itech r35
Problems:
sound muted after 2 seconds of music.
audio players used:
audio manager
windows media player
i tried your advices, but not worked for me....
Sometimes it works when i put 70 (binary) on both Maxbitpool and bitpool...but on next device activation or reboot it just stop working...

A2DP and wireless
Just to be clear, my results are when I do not have wlan activated.
I changed UseJointStereo=dword:00000000.
Quality is good and it is definitely stereo.
Still have the auto detect problem. Interesting though, if I walk out of range for a while with the headset on, when I come back into range the A2dp is autodetect and the music starts playing through the headset again, quality is good. If I soft reset with the headset on and A2DP is autodetected, the headset is unusable.
If you do any of this with wlan on the quality is very poor with starts and stops.
Also noticed that audio manager does a better job with bluetooth than gsplayer, I think audio manager may have better caching.

Freezing
I think there's a problem with the latest core os files (AKU 0.7.0)... i havent' tried the MS BT stack, but with the Widcomm, using the bluetooth for anything more than 1 min, completely freezes the phone.
It does when listening music, transferring files, etc... if BT is idle, nothing happens (except than freezing the device when the Comm Manager gets confused and enables BT instead of gsm radio).
So it seems related to the core files.
Switching on and off, transferring data thru BT is a critical task and subject to lockups.
For the record, i used to use the BT A2DP and file transfer without ANY problem whatsoever in my old and horribly-underpowered HTC Tornado (omap850 @195mhz) so IT MUST WORK!

im using your latest rom and Motorola HT820 does not have a problem with it... even in the earlier roms you cooked... even tried it in indra's xoj version and darkforce's rom..
just wanted to clear it out just so you can rule something out...

Plantronics Pulsar 260
Sound stops coming fter about 1 second of playback (used TCPM,
Audio Manager)
The same result after applying those reg mods....

Please try and install the stack found here: http://forum.xda-developers.com/showthread.php?t=291639
A2DP problems should go away, but then will come the freeze-after-1-min problems, like with my HP Stereo bluetooth headset

I've flash to your latest WM6 AKU 0.7 (WIFI Fix update 3) ROM just now. But sadly to say, the freezing thing still occurs after playing music with Audio Manager. It even freezes when watching videos using WMP. Usually around 1 minute it shall start freezing. FYI:
Bluetooth model: i-tech Clip

I had the Qtek 9000 with italian version WM5 and i flashed WM6 with no problems. if you dont wanna have any problems unzip the attached file and add in the folder the 3 files (ms_.nbf ; nk.nbf ; radio_.nbf) from your prefered WM6 ROM (I personally use the latest Laurentius & Beast ROM http://forum.xda-developers.com/showthread.php?t=325466) start into bootloader (Power+backlite+softreset) and ROMUpgradeUt.exe
VERY IMPORTANT: you have to charge your batery before any flashing

A2dp motorola S9+windows xp

first off, major props to the xda community, you guys are the best!
now for an interesting problem/project:
It's been a month since I've purchased my Motorola S9 bluetooth headphones http://www.motorola.com/motoinfo/product/details.jsp?globalObjectId=177 and have been amazed by what I can do when combine the S9 with my HTC touch and cyberon's voice dialer which is a voice activation program
I use it to:
listen to stereo music
launch programs
stereo music remote control
speed dial
raise and lower volume
teach iphone users the meaning of envy
just being able to do that with with the a2dp remote and microphone of the s9 makes it feel like it's 2030 where people are wired to computers and technology is transparent and everywhere. The s9 feels like sci fi technology... almost. the s9+htc touch is a great no hassle way of getting the information you want pumped into your ears
so as a tech enthusiast I've asked myself,
why the hell can't my computer do this?? i mean, it's 2008 and I'm still using a keyboard and mouse for everything?
I'm trying to make the S9's work on my mac book pro running windows xp+bootcamp drivers but windows doesn't even support a2dp much less handsfree wireless mic profile
i've an online tutorial by katy hxxp: www.djkaty.com/drupal/vista/bluetootha2dp but installing broadcomm's bluetooth stack gives me an error telling me that there is no bluetooth radio device detected which is total bull as i've been able to send files to my HTC touch via bluetooth. I've also tried installing another bluetooth replacement stack called bluesoleil; with no luck
I've also am about to start trying adding widcomm using this guide (http://www.dev-toast.com/2007/01/05/uncrippling-bluetooth-in-vista-rtm)
but in the guide said a2dp doesn't work with widcomm
anyways how do i make bluetooth a2dp work and my s9's mic to work via bluetooth on pc? is my ultimate question
also, if you could recomend a voice activation program that works as well as cyberon's voice dialer I'm looking for the type of functionality where I can press the voice button issue a command and then good stuff happens I bet lots of other people thought of doing the same thing like this
could you please help?
A step by step guide would be aprechiated

update: I've been able to install widcomm drivers version 5.1 and everything works... except the a2dp UGH!

BlueSoleil, with some external BT dongles, does support A2DP. It's just that the BT dongle itself must support it in hardware.
That is, shop for an external BT dongle if you do need A2DP.

A2DP and bluetooth stack
Having same issues here. My goal is using BOTH A2dp and Blackberry wireless sync via bluetooth (just a serial port).
I find it impossible as Blackberry will only work with native xp drivers and A2DP is not supported in xp.
Currently i gave up wireless sync and am using A2DP with Bluesoleil, which works fine for me.
Anyone ever tried using A2DP WITHOUT switching to a different bluetooth stack?

Bluetooth stereo headset bugs (handsfree mode fail & device.exe crash)

I've noticed these similar (and likely related) bugs in a lot of places and have been living with them for six months, but I have never seen a fix. Surely there are others with this issue that might be able to fix it.
Issue #1: When you connect a Bluetooth stereo headset to a Windows Mobile device, using the Wireless Stereo AND Hands Free profiles, the wireless stereo feature works fine, but when attempting to answer a call, hands free fails. The hands free icon shows on the Phone screen, no audio is heard, and after a few seconds the headset shuts off and the icon goes away.
Issue #2: When you connect a Bluetooth stereo headset to a Windows Mobile device using the Wireless Stereo profile and are watching video in Windows Media Player, if a call comes in, the program device.exe crashes and Windows Media Player will often need to be restarted. Device.exe will often crash at other times as well.
I have seen numerous reports of this problem, and near universal reports of it on the Dell BH200 Bluetooth Stereo Headphones. It seems to require A2DP, and be very common among HTC devices. I have had the same problem on the AT&T Tilt (Kaiser) and AT&T Fuze (Touch Pro/Rafael) under Windows Mobile 6. I can confirm the headset works as it is supposed to on Palm OS (Palm Centro) in headset mode, and that it was also able to work as a headset on the T-Mobile MDA (Wizard) running Windows Mobile 5 (which does not support A2DP).
In all cases, I am talking about devices using stock ROMs.
If you have seen the problem, please list the device, OS, and bluetooth device used. If you have a bluetooth stereo headset that does not exhibit the issue on devices that are known to have this problem, list that as well, so owners of devices with this issue can consider alternative headsets.
If you have any technical knowledge of what causes the issue, please share it. If you have heard of any workarounds, please share it.
Thank you all.

I have the Samsung i-640 running WM6 and have the same issue with The Dell BH200 not doin Hands free mode and the whole shut down of device happens too ..very Frustrating .
I tried using the Nokia BH 100 which does only Mono [Hands Free] and i get $hit loads of static noise but the Device doesnt Shutdown.

Heya, I have the AT&T Fuze and I also own the BH200. I have the same exact issue you have (issue #1). I have no idea why it does this but I've been trying to get support from dell for the longest time with no luck.
I think the problem lies in the MS BT stack. It does an automatic pin guessing thing which might cause the bh200 to not work properly. I have tested the fuze on the BT2020 (by Jabra) and it works perfectly. I just recently bought the moto s9 (still waiting for it to arrive) but I would prefer to use the dell bh200 if possible.
Check my sig for the information you're looking for.

Dell sends you to PC support when you try to get support on the device, since it's usually sold as an accessory with computers, but they refuse to offer actual support on the actual device, as though they knew nothing about it or how it works. I asked them if it was a rebranded version of another company's headset, and they wouldn't say.

I tried to get help from dell already, and they're as much help with it as telemarketers...

Similar problem
Maybe this is a stereo headset bug...
Maybe this is designed behavior, but it is typical of why people HAVE to hack the crap out of WM to be happy with it:
I have a ATT Tilt.
Behavior same under WM6 and WM6.1
I have a Jabra BT610s (stereo headphone with A2DP, AVRCP, handsfree, & wireless stereo profiles).
If the Tilt is paired with both wireless stereo & hands-free, then even if Win Media is running or playing, the hands-free profile is selected when powering on the headphones. Then, the stupid ATT Bluetooth settings are so buried that it requires about 30 secs of sylus picking, poking, and prodding to get it set to wireless stereo.
Is there a way to set the Tilt to default to wireless stereo, is there a helper app for quick-switching this?
Also, there are not infrequent dropouts in audio over bluetooth, even with the phone setting on the desk 24" away from the headphones as I type this.
All the remote control features DO work with this setup, but unfortunately there's no remote control function for profile switching.
Thanks,

I am using a stock ROM and I don't have the above problems. I am using a motorolla hb820 headset. I also use an LG Style i headset, and no problems either. I use Core Player and it plays fine even after a call. I only use WMP to play music and my X7510 haven't froze yet while playing music when a call comes in.

Hi
I am using Lg KE590 but I am not using the device so I have not gone through the problem. Is it for all the handset ?

Don Joao Resort

I have several configurations with problems to report below:
1) HTC P3600i (WM6 stock ROM) + Dell BH200 => issue #1 (never try issue #2)
2) HTC P3600i (WM6 stock ROM) + Dopod HS01 clip-on BT stereo headset => All functions work fine, no problem switching between profiles
3) Dopod S300 (WM5 stock ROM) + Dell BH200 => stereo music & phone call works but music switch back to the phone after end of a call
4) Dopod S300 (WM5 stock ROM) + Dopod HS01 clip-on BT stereo headset => All functions work fine, no problem switching between profiles
5) Nokia 5610 Xpress Music + Dell BH200 => All functions work fine, no problem switching between profiles
6) Nokia 5610 Xpress Music + Dopod HS01 clip-on BT stereo headset => All functions work fine, no problem switching between profiles
Summary: I tend to believe that the problem is specific to Dell BH200 and some of HTC's or WM OS combination as Dell BH200 works fine with Nokia phones and Dopod BT headphones always work with any phones we have.

Reporting in, Im using Motorola S305 Stereo BT. No above issues whatsoever with 2 devices HTC Kaiser and Touch Pro. Both with stock or cooked ROM. I have a strong feeling its related to hardware prob on Dell BH200.

I have a touch pro that refuse to play nice with my AVIC-D3 head unit...I must pick either headset profile or wireless stereo profile, but not both. I remember coming across a solution called a2dptoggle. It let you switch between the 2 easily (in wm agenda page), but try it out to see if that's a solution or not.

Issue #1 using HTC Touch Pro and Dell BH200
Because of that issue i can't use the hands free function at all.
Only way i can use my headset is:
If i uncheck Hands free from partnership settings, then an incoming call mutes headset, i take out the phone have my conversation manually, after hangup the music plays on.
