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 ?

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.

bluetooth and sms tone questions HTC MOZART

hi all
dont know if anyone can help or point me in the right direction but i found this yesterday
Phone music & calls to PC Speakers
For me the headset & AV service work perfectly, straight away.
Turn on bluetooth, pair with your PC, and touch again to connect.
Apparently my old HTC Desire had these services (AV Source and Headset) but it always paired but didn't maintain a connection... no obvious reason, didn't bother to look up why lol.
I was just excited when as soon as I connected with my PC with WP7, the Headset service asked for permission and after that all phone audio came through!
Old news to some but it is really cool having your phone blast music through your PC speakers wirelessly absolutely no effort or hassle at all!
NOW IVE PAIRED TO MY WIN7 LAPTOP BUT WHEN I TAP ON COMPUTER ON THE MOZART IT COMES UP NOT CONNECTED. ANY IDEAS?
SECOND WHEN MY MOZART PLAYS SMS TONES WHEN PHONE IS IN STANDBY ITS LIKE IT HAS A HICKUP, IT STARTS PLAYING SKIPS AND FOR PERHAPS 1/2 A SECOND AND CARRIES ON. ANY IDEAS ON THAT ONE EITHER?
THANKS EVERYONE IN ADVANCE FOR YOUR HELP

Navigon Mobile Navigator leaves phone speaker enabled when connecting to bluetooth.

Android Froyo, HTC Desire HD with Navigon Mobile Navigator.
I can connect the phone to my car stereo through Bluetooth. Everything works fine. I can receive and make calls and music routed through to Bluetooth perfectly. When I use Mobile Navigator the turn-by-turn instructions come through the phone speaker, then a second later they also come through the bluetooth connection to the car. The beginning of the bluetooth instruction is also cut off. I can't find anywhere to explicitly disable the phone speaker when audio is routed to Bluetooth, although other apps don't seem to suffer from this. Anyone know a hack?

Same Problem here. sound is routed through bluetooth and phone speaker while bluetooth is cut off. I assume the Navigon software has a bug here. I hope they fix it soon
unfortunately I did not find any workarround or fix till now
anyone?

I had a workaround using car UI by beemer. Unfortunately after upgrading to android 2.2.1 I can't make it work anymore but am not sure where the problem lies as even downgrading again through backup-restore left the same problem. I'd be interested to hear if anyone has a magic trick for producing the right combination of settings as I know this was working before with a 2.2.0 based rom and car UI.

[Q] In-car Bluetooth with Mango

I've looked for threads relating to this specific issue both here and in Google, but found no results yet.
I have a HTC Trophy that was previously connected to my car's Bluetooth system - I was able to browse my contacts, place and answer calls. This worked both on the launch firmware and in the NoDo update.
I recently upgraded to the Mango developer beta (needless to say - I'm not a registered developer...), and the Bluetooth seems to be having some problems. Just to be clear, I've already deleted and repaired the devices, even rebooting the phone and turning off the car first. The thing is: the phone connects to the car, and it even reads text messages out loud and takes voice commands (e.g., "call back" or "ignore" on the text message)... But calls simply don't work, whether I'm placing or answering them: the car's screen simply shows a "connecting" message, but the sound doesn't get put through. The phone also shows that it is placing the call. If I'm answering a call, the car displays the "connecting" message and the phone simply keeps ringing.
Does anyone have the same problem? Are there any reported fixes?

I have the same issue with my HD7 connecting to my factory fitted BMW unit in my E46.
The phone and car pair up, I can read my text messages on the nav unit, but incoming and outgoing calls only route through the phone, not the head unit.
I was having issues on NoDo as well where connection would keep dropping.
Since I installed Mango 7720 it has a stable connection, but no audio.
Head unit works flawlessly with my iPhone 4, so I'm guessing the HD7 is at fault somewhere.

The upgrade to 7720 solved the issue for me - calling and message reading are both working fine. The contacts don't all show up on the car's screen, though...

EvilAgent, Do you happen to have a BMW? I have a trophy with 7720 and when streaming mp3's over bluetooth to my car, the audio quality is bad. Do you have a similar experience?

It is a BMW, but I don't use Bluetooth to listen to music, I just go with the cable

[Q] WP7 BT issue

I m having issue of my Focus's BT not working. Whenever i turn on the BT is goes into searching mode and doesn't come out of that.
anybody facing the same issue?
mine is OS version: 7.10.7720.68

Not exactly, but in my opinion WP's Bluetooth software is just horrible.
It has two options - on and off. You can't change your phones BT name, you can't be invisible with bluetooh on, you can't transfer files. My sister can't sync her WP with her car, whereas I (on Android) just turn BT on and it syncs instantly.
I hoped Mango would fix that, but it didn't. It's just crap.

bluetooth isn't the best part of wp7 for sure...but it sync easy with an headset or a car stereo...
reading some threads about it i found that samsung devices have the worst wp7 BT hadware...
still, i'm alright to say that files transfers should be enabled

hmmm....my focus synced with my car stereo once....but recently it has started go into "Searching" mode and doesnt sync with car stereo

I only use Bluetooth in my cars and all my previous phones worked perfectly (iPhone, iPhone3G, iPhone4, Lg Quantum, Samsung Focus).
The HTC Titan on the other hand sucks. My two vehicles handle things different.
The Challenger (factory BT) will hold onto the call even if the car is off and the door open. The call will switch back to my old phones when out of range (basically in the house) or i manually shut off bluetooth.
The Jeep (aftermarket radio) once you open the door with the car off the call goes back to the phone.
The Titan has a problem were 1/2 of the time when the call is transferred back to the phone either manually, because the car turned off, or im out of range. The mic will not engage. I can hear the person but they cannot hear me.

Haven't had a problem with my Trophy... previous car was a Lexus IS220d and it synced and worked fine.
Currently driving a Jeep Wrangler and only once I've had the "searching for device" issue.

Bluetooth on Wp7 is quite poor. You can not select, which service an adapter shall support (handsfree and A2DP). It always use both services.

Windows Phone's Bluetooth support is abysmal, but you know what's worse: Samsung's support for Bluetooth on Windows Phone. Their last firmware update for the AT&T-branded Samsung Focus reduced out-of-call Bluetooth volume so that it's way too soft and text-to-speech is impossible to use because you can't hear it. If you turn up your Bluetooth headset or car volume to compensate, then in-call volume is way too loud. There is no fix or solution, except to restore the old firmware through Zune's backup. I've been running 2103.11.3.3 instead of 2103.11.8.1 for about 5 months now. I couldn't be more furious about Samsung and AT&T's lack of urgency to fix, or even acknowledge this. I'd even deal with the disappearing keyboard (as I have anyway) if it means keeping Bluetooth working. Regardless, after this experience I will never buy a Samsung phone again.

WP7 lacks rSAP, and for many of us with European cars are SOL. Wish Microsoft would listen as many of us have complained about needing rSAP.
