Had the same issues: connection seems fine, but most of the time no sound at all.

I tried different solutions found on different websites, but for me, this one fixed all my bluetooth issues: http://www.everythingwm.com/forum/moto-q-9c/q9c-and-infiniti-g35x-bluetooth-problem-16833-4.html

I applied the registry settings (not all reg keys mentioned did exist on my phone), re-paired (renault built-in carkit), and bluetooth is working fine now.

Similar Problems on GM

I wonder if we are having problems stemming from the same root cause or multiple root causes.

Regardless, I'm having similar problems on a 2009 GMC Yukon with built in Bluetooth. The phone is connected and rings through the auto, but when I hit the off hook to answer, I get no sound and the caller gets no sound. It appears everything connects and the phone says the call is connected, but no good. Usually if I initiate the call from the phone it will work correctly and sometimes not.

I solve it be deleting the phone from the car and the car from the phone and re-pairing, but it only works well for a short while then it fails again.

I'm hoping someone comes up with a great solution(s).
[Touch Pro2, Tilt 2 Windows Mobile General] Loki007:
Well I'll be... That is what fixed it! Well, not really a fix as I have to disable my data, but actually makes it usable.

Do you know if there is an app out there for this? NoData, while great, doesn't shut down the connection. There is a donation if someone will write one for me :)
[Touch Pro2, Tilt 2 Windows Mobile General] Loki007:
Did you create the missing keys/folders or just make changes to the keys you had?

I'm willing to try anything to not have to disable my data everytime I want my phone to work! Yes, I'm that lazy to expect things to work right the first time :)
[Touch Pro2, Tilt 2 Windows Mobile General] Loki007:
All right! Got it fixed, thanks guys.

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 DisableReopenAudio to 0 (default is 1)

3. Reboot device

I tested it for a few minutes and it was solid and sounded good, no freaky occurances. We should sticky these for other people having BT issues...

thats good news loki but some values i can not find in my registry i will try to add them and then give it a go
[Touch Pro2, Tilt 2 Windows Mobile General] Loki007:
Yes, I added the missing ones, restarted the phone, re-paired with my car and, so far, works great. I'll give it a week before I start doing the happy dance.

is it possible to make a cab or reg key file for it
[Touch Pro2, Tilt 2 Windows Mobile General] Loki007:
I can create a reg for all the keys except the HFBDA key. That should match the LastConnectedBDA key which may be different on our phones. What is yours set to? Mine is 00,1e,ae,20,c2,80. I wouldn't want to have someone import it when the setting isn't right for their particular build/version/etc.

Could anyone explain what these settings mean? There is no point of tweakin something if I do not know what each of setting does, well of course it has a point of tweaking it, but I would really like to know what it means.:) Does anyone has a problem syncing the phonebook after aplying that tweak or it is just me?

Thanks for help!
[Touch Pro2, Tilt 2 Windows Mobile General] dahauss:
Can someone explain what all of these REG changes do?? I dont want to end up like before. There was a CAB floating around that was supposed to fix the BT issues and while it made it better it drained my battery VERY VERY quick.

Do these changes have any effect on battery life???
[Touch Pro2, Tilt 2 Windows Mobile General] dahauss:
WOW.. now when my TP2 rings, I actually get the custom RINGTONE out of my GARMIN NUVI SPEAKERPHONE and it doesnt DROP calls right after the first ring AND I can answer and hangup fine.. the phone book is still a little messed up in that any contact with ONLY a COMPANY NAME and not a first and last name loads as a phone number in the name field...

Does anyone know if any of these REG changes degrade battery life? I am asking because a while back I had a CAB that was supposed to fix the bluetooth and while it improved the paring, it drained my battery live very very fast.

Also can someone explain WHAT these reg changes and additions do? I would really like to know what I am doing to fix the issue...

[Touch Pro2, Tilt 2 Windows Mobile General] dahauss:
One more thing, now with the fix, it appears on my garmin, when I press LAST DIALER, LAST RECEIVED or MISSED, I get NO DATA AVAILABLE .. I didnt have this problem before the fix.. Is there a solution??

Thanks....
[Touch Pro2, Tilt 2 Windows Mobile General] batpot:
correct; mine is different from that.

also, the bdaddr key keeps resetting itself when I reboot my phone.

I even tried changing the key type to something other than binary, and it still reset itself to binary, and changed back tot he default value.

These hacks did not work at all.

I came across this cab that changes some BT settings, but at least one guy reported it draining the battery very quickly (not enough posts to post links...sheesh):

Does anyone know what the SupportedFeatuers in [HKLM\Software\WIDCOMM\Plugin\HandsFree] do?

My default is 1383, but every instance of this hack I come across shows the default as 1135, and always change it to be 45.

Who came up with 45 as being the magic number? Why not 47?

Fix for Parrot Car Kit and TP2 Freezing

I just thought I'd let everyone know that this fixed my HTC Touch Pro 2 from freezing after making a call using my Parrot Car Kit.

Change this only:

HKLM\Software\WIDCOMM\Plugin\HandsFree

Change SupportedFeatures to 45 (default is 1135, although my was something different)

My Touch Pro 2 no longer hangs or freezes and I can immediately make another call without waiting a minute or so between calls.

My ring tone also now comes out of the car speakers, so I don't have to put up with the Parrot's default ringing.

I hope this helps other people, as I've been looking for a fix for ages.

Thanks go to the members of xda-developers and the people way smarter than me that worked this out.

SupportedFeatures

This seams to be a bitfield, havn't figured out the meaning og the bits yet. But I got call logs working by changing the value to 1141 (1137 after reset). But one time the audio got missing so its not working to 100%.

/Fredrik
[Touch Pro2, Tilt 2 Windows Mobile General] 2manytoys:
Yes, no problems. The callers names come up on the Parrot screen when they call. It works just like it should, with an added benefit of having my ring tone come through when someone calls.
[Touch Pro2, Tilt 2 Windows Mobile General] rcs_br:
Ok, I have tried everything I could find as possible solutions, with the exception of the 1141 entry for SupportedFeatures as indicated two posts above (will do that today for sure).

Meanwhile, I came up with a completely different workaround I though I could share:

I tested (and purchased after I confirmed it works) an app from AGEYE called G-Profiles (link: http://www.ageye.de/index.php?s=gprofile/about). Although not perfect, this app has a lot of options that came in handy. Then I created a generic profile and another for in-car use. The in-car profile is triggered by the connection of a handsfree. In this profile, I added a command to run another app which is called Manila Dialup Enabler Disabler (link: http://xdaforums.com/showthread.php?t=610657) which now supports command line interface. I added the CLI parameters /STOPALL /DISABLEALL which disconnects all data and keep them disconnected until you run the app again.

With this I have the option of keeping the registry as it is, which means, in my case, still being able to see phonebook and call logs, which I couldn't with all versions of the registry hack we have been discussing here. And I have a way to automatically disconnect data and keep it off until I disconnect from the car handsfree.

It is not an ideal solution, but I can live with it until HTC decides to fix what they should have made right upfront.

[Touch Pro2, Tilt 2 Windows Mobile General] dahauss:
Mine was set on 45 and while it worked, none of the call logs works with my garmin. Also, sometimes I had the issue where the garmin would ring and then the bt connection would disconnect.. NOW with 1085, it works 100% better and the call logs seems to work. I can see it pull the new ones (hour glass on gps)... the only issue I still have is any contact that ONLY has a company name and not a first and last name show up in the garmin phone book as ONLY numbers (IE a phone # where the name should be). Is there any way to resolve this?? I can still search for the business and it comes up but doesnt display in the garmin phone book list...

Special Procedure (Jabra BT Speaker Phone)

Hi all

I am sorry if this seems somewhat benal but I have always found Trial and Error productive to a certain extent.

I have found that to get the thing working the way I want I have to follow this procedure:

1) Switch on the BT Speaker Phone and wait for the low tone that tells you it couldn't connect.

2) Turn on the Bluetooth on the TP2.

3) The phone will automatically connect over Hands Free Profile.

4) Open Bluetooth Manager and manually connect over Stereo Audio profile.

When I follow this procedure I get both Music (BT Stereo) and Calls (BT Handsfree) going to the BT speaker without problem.

Hope this helps somebody!

Thanks

Hi All!

I've always problem with bluetooth connection on my car (Lexus RX300). The connection is ok and even the control on my wheel, but the audio for the other person is orrible (it is metallic and not fluent)

On my TouchPro2 the registry

HKLM\Software\WIDCOMM\Plugin\HandsFree

is by default on value 1379

My Rom is TiR v20 CE 6.5.21884 (build 21884.5.0.85), even if this problem are always present with a lot of roms (original HTC too!)

I set the value at 1085 as read here, and after a soft-reset the value auto-changed on 1081

I'll try this configuration!

BYE
[Touch Pro2, Tilt 2 Windows Mobile General] 2manytoys:
Just to clarify, when I used 45, the phonebook would sync no problem, and the name of the caller shows on the Parrot Bluetooth Car Kit screen. I do notice that the call log isn't there anymore. Sorry if I led anyone down the wrong track with this. I personally don't use the call log, so it's still all good for me. The has changed the whole experiance, and now the phone is fanstastic to use.

Cheers.

PS: I'm using WM 6.1 too. It's much faster than the 6.5 versions out there in my experiance.

Man, how is the 'stereo audio' in your car? In mines (Ford Fiesta with MyConnection) seams like 'mono'.

For call everything is good, but to listen music from my TP2 on car the sound is terrible :(

Hi cpimentel

Sorry to hear that your experience is so bad. The sound I get is really quite good - which was to my surprise as I am used to pretty poor quality from these kinds of devices via BT.

Which of the HLKM\software\widcomm\plugin\handsfree keys need to be set to 1085? Do I need to do all the reg entries in the beginning post of this thread? Or just change one to the 1085?
[Touch Pro2, Tilt 2 Windows Mobile General] prubin:
Apparently, some folks have been successful with just changing to "1085" as set forth in prior post:

I can confirm that "1085" for HKLM\Software\WIDCOMM\Plugin\HandsFree works perfectly with my Land Rover 2008 LR2 bluetooth system.

I have made all of the registry changes set forth in the earlier portion of this thread.

1.Navigate to HKLM\Security\Policies\Policies\

Click "Values" soft-key

Change "00001001" value to 1 (decimal) (recovery note: default is 2)

Change "00001005" value to 40 (decimal) (recovery note: default is 16)

Reboot device.

2. Modify the HandsFree plug-in:

HKLM\Software\WIDCOMM\Plugin\HandsFree

i. Change SupportedFeatures to 1085 (default is 1135)

ii. Add value HFBDA binary, set to same value as LastConnectedBda

iii. Add value HFDeviceType decimal 2

3. Modify the WIDCOMM bluetooth general settings:

HKLM\Software\WIDCOMM\BtConfig\General

i. Change bdaddr to (no value)

ii. Change DisableReopenAudio to 0 (default is 1)

4. Reboot device

See what works for you.

Out of luck

Well, I guess I'm out of luck. My Tilt2 won't keep the bdaddr at no value. It resets to the original value on soft reset. Other than that, while the phone links to my Hyundai Genesis, it won't let a call through. The only problem I have with the stock ROM and registry is that I have to turn off Data Connection in order to accept an incoming call. Everything else works. But the data connection turns itself back on automatically.

Thanks for the help prubin!
[Touch Pro2, Tilt 2 Windows Mobile General] prubin:
Make sure that you are setting the bdaddr to "binary", not "decimal".

Look at the instructions again (especially the part below - follow the instructions exactly - your Tilt2 will work):

HKLM\Software\WIDCOMM\Plugin\HandsFree

i. Change SupportedFeatures to 1085 (default is 1135)

ii. Add value HFBDA

binary

, set to same value as LastConnectedBda

iii. Add value HFDeviceType decimal 2
[Touch Pro2, Tilt 2 Windows Mobile General] gramig:
Hmm

bdaddr already exists as a binary vaue, default value is 00 23 76 38 94 F9. Deleting the values changes everything to 00. On soft reset changes back to default value on it's own.

My default supported features is 1383. Changed it to 1085.

Added HFBDA as binary and set it to same value as LastConnectedBda. 00 0E 9F 6C F1 C1.

Added HFDeviceType as a dword set to decimal 2.

Repaired phone. Still won't relay an incoming call. Didn't try outgoing. But outgoing worked fine with stock registry.

Also I don't have a DisableReopenAudio under the btconfig\general. I did add it as a dword 0.

Am I still doing something wrong?
[Touch Pro2, Tilt 2 Windows Mobile General] prubin:
i have last HFBDA at 00 1E AE 2A 80 92
[Touch Pro2, Tilt 2 Windows Mobile General] gramig:
I have no idea why the difference. But my values have been the same since I got the phone.
[Touch Pro2, Tilt 2 Windows Mobile General] prubin:
sometimes, after you edit the registry, you can get settings to hold if you power off the phone, then wait a minute before powering back up.

Works for me too

I can confirm that "1085" for HKLM\Software\WIDCOMM\Plugin\HandsFree also works perfectly with my Volvo hands free kit.

[Touch Pro2, Tilt 2 Windows Mobile General] kenny hektik:
YAY! And uh-oh...

Thanks to those that provided the registry tips for the bluetooth. Also I wanted to add one other thing. If you are using this in a car stereo, if the option is available you should also try updating your BT firmware.

I have a Kenwood kvt-514 H/U with the BT-200 module for bluetooth, and updating the firmware helped, I have less issues with pairing (I have a bunch of BT devices associated and sometimes when I went from House to Car, it'd freak (house uses BT too, so when I walk in passes all Cell calls to cordless home phones).

The registry tweaks helped a lot. My stereo by default had an annoying ring. Now it passed the phone audio/rings along. I have been meaning to try it with the MSvoice to check caller announce, but I am sure that will work fine. Phone Book, call logs, battery indicator, everything works great - accept one little oddity I have hit.

If i have to use the keypad for any DTMF interaction, such as voicemail, call screening, etc. The DTMF tones are really long now. Say I press "1" to answer a call. The tone lasts for about 5 to 10 seconds (maybe longer), on the bright side it doesn't seem my caller hears it. Just me.

Has anyone else seen this, or have any input on how I can fix this - or where to begin looking?

***Follow Up***

I grabbed a new ROM, and I tested the bluetooth piece out before I made these changes. I must have been smoking crack, because the the long DTMF tone is there as well. This happens on not only my car stereo, but also on headsets. I will keep poking around and try to figure this out.

***Follow Up #2***

So after the default ROM install, and the BT still giving the long tone I just installed the BT cab and made no other changes and the long DTMF tone issue is gone. Everything else is working, address book, ring tones coming through along with call announce (MSVoice). YAY!
[Touch Pro2, Tilt 2 Windows Mobile General] looking-g:
Final fixed this issue by coincidence. I tried to sent a contact with bluetooth to the touchadapter, it will also ask for the PIN and when you enter this you get the message that this service is not supported on the touch adapter. But never the less it is paired and in your BT list now and able to connect.

I bought a car kit MP3 player for my car. I paired it with my TP2 and enabled the "BT Audio" and "BT Handsfree". Outgoing calls work fine with no problems at all. But during incoming calls there is a problem. If the incoming call is from someone saved in my contacts, the BT carkit does not ring. If its from an unknown number (not saved in my contacts), it works perfectly. I tried all the tweaks and hacks in this forum but nothing worked. Anymore ideas.

My wife's TP2 was also having problems with her Kenwood headunit/BT-200 car bluetooth system [btw, the BT-200 is made for Kenwood by Parrot].

I'm saving these hack settings, but we're all good.

Oh, it is a Sprint TP2 running the Sprint/OEM WM6.5 OS on the phone. The phone worked ok back when it had the WM6.1 system, but the WM6.5 update killed the compatibility. Now it is better than before!

Update.

I got a fix for this from HTC, and they told us that this was for both HD2 and TP2.

The thing is that the installer fails on TP2.

I extracted the exe container ( for use with Active sync) and then opened the Cab file, and viewed the xml file included.

This file was refering to an attached file called CLCC_Setting.exe, which is included in the package.

I extracted the file, and have attched this as a zip for you guys.

This file when installed on the TP2(and HD2) gives you the option to set "standard" or "Volvo"

Let me know how you get on.
