Hi, I have a Renaultsport Megane with integrated Parrot bluetooth kit and I can pair my device but nothing else. When I pair it shows on the phone and I receive the connection message on the car display but all the phonebook and call history show as empty and when trying to call someone it ends the call before it starts ringing.

I've contact HTC and got the exact same auto reply as earlier in this thread so went back to them and asked if they could look into it and not send an auto reply as the problem has been identified as the non standard bluetooth software now being used on the TP2 and HD2 as it no longer uses the standard Microsoft bluetooth stack as used by most Windows Phone's. The lack of this support means the phone's are not compatible with a large number of devices including Microsoft bt dongle's as I use on my PC.

I've reported this as the problem and they have come back to me saying do not make any reg changes as they will go and look if there are any quick fixes to allow my devices to access the HD2 and come back to me. I suggested if it would be possible to allow the phone to use the Microsoft BT stack so hopefully there is a way to do this and we can all use the phone over BT as it should.

Success!!!

I tried the settings posted on the previous pages and for the first time my HD2 pairs with my Range Rover handsfree. :)

I didn't find the registry values exactly as in the previous post so here's an updated list of what worked for me:

I downloaded Mobile Registry Editor (freeware from here http://handheld.softpedia.com/get/Desktop-and-Shell/Windows/Mobile-Registry-Editor-10636.shtml

Then I made the following registry changes:

1. Modify the HandsFree plug-in: HKLM\Software\WIDCOMM\Plugin\HandsFree

i. Change SupportedFeatures to 45 (default is 1135 mine was 1379)

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

iii. Add value HFDeviceType DWORD 2

2. Modify the WIDCOMM bluetooth general settings: HKLM\Software\WIDCOMM\BtConfig\General

i. Change bdaddr to (no value) delete the existing key value

ii. Change DisableReopenAudio to 0 (default is 1) I didn't have this registry key so I created it with DWORD value 0

3. Reboot device

This works for me. I made about 4 calls from the car and then I lost the connection to the phone but switching bluetooth off/on reconnected it again. So it's not perfect but it is far better than it was. Many thanks to the previous poster for the info.
[HD2 General] Milo Rambaldi:
I applied the registry change you suggested and so far it works. No more loss of connection between the HD2 and the in-car BT (BMW iDrive).
[HD2 General] catastrat:
Works for me as well! I applied the same changes in the registry and so far so good - I can connect, download the address book, and even see who's calling me!

Great post, lupinaro!
[HD2 General] buffystar:
Works perfectly on my Alfa/Fiat blue and me system except for text reader which only seems to work on Motorola phones anyway

I only can´t paired my phonebook, but i believe it is possible.

My HTC HD ID: 1.48.412.2

Hello

What kind of value did you puted for HFBDA because me I don't have the entry LastConnectedBda

Thanks in advance

MERY CHRISTMAS
[HD2 General] andy2111:
Merry Christmas to you too!

The value I have for LastConnectedBda (Binary Value) is 00 1E AE 03 B5 F8

It might be worth adding in the value for LastConnectedBda so you have this as well as HFBDA.

Good luck!
[HD2 General] Looking Glass:
The BT agenda issue.

After many tweaks on the registry (most of them in this thread), changes in the BT files on the TT .cab instal file, etc. I ended up with the most stupid thing that makes the HD2 stall: the contact list transfer (phonebook).

If when asked by the HD2 to allow your car BT to donwload your phonebook, you DO NOT ALLOW it to proceed, the rest of the functions work OK WITHOUT any registry change. You have to ommit to tick the box "allow all connections to this device" (your in car BT) and reject the permission to download the phonebook. (it has to be done each time you get into your car and they connect)

It's a multi-sided problem, since if you use also TT, the TT installation has to be done either without the BT files or via the "install to SD" and then Hard Reset, to avoid the "extra" conflicts.

After that, I've got no problems during the calls, not for answering or making voice dial calls, not any "additional" lag on the Navigation program, not the full hang-ups i had constantly.

It took me two weeks of tests to get to this conclussion, hope it helps someone else.

Regards.

Works fine except phonebook with BMW X3 E83 ULF

What I did:

1. Modify the HandsFree plug-in: HKLM\Software\WIDCOMM\Plugin\HandsFree

i. Change SupportedFeatures to 45 (mine was 1379)

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

iii. Add value HFDeviceType DWORD 2

2. Modify the WIDCOMM bluetooth general settings: HKLM\Software\WIDCOMM\BtConfig\General

i. Change bdaddr to (no value) delete the existing key value

ii. Change DisableReopenAudio to 0 (default is 1) I didn't have this registry key so I created it with DWORD value 0

3. Reboot device

I see that:

- Supported Features will revert to 41 (will not remain 45)

- baddr has its value again after reboot

I don't see any icons like RF, SMS... the phonebook tells me "empty". But voice seems to be working fine. Because the phonebook will not work I can't see the names, I see the phone numbers when I'm called. But yes, still better than nothing!

BTW: I sent an request to HTC, I hope they will fix that soon!
[HD2 General] AvRS:
I think the more people that complain about this the sooner they'll fix it. The last response I had from them on xmas eve was to make sure I've updated my phone with the latest patches and ROM upgrade. I replied saying I'm on O2 so can't do the ROM upgrade but have added the patches, not that they're related to the BT at all, I just think they're now trying to put me off. The rep said that if I still have the problem after all updates it will be passed back to development as a matter of urgency so fingers crossed it's dealt with soon.
[HD2 General] s0uthpaw:
This worked brilliantly for me. I have a Pioneer Avic car kit, and it would crash when incoming calls ended, requiring the ignition to be cut to reboot the device - a complete pain, obviously.

Thanks to the guys who came up with this one.

Problem with addressbook on XC60

Hi,

The problems I had with my Volvo XC60 connecting to HTC TP2 consisted of having no audio after call setup. Pairing and synchronisation of addressbook went fine, but tere was no audio after call setup (which is quite essential :))

I've also implemented below modifications to the WIDCOMM plugin. Now I have (same as Mike) problems with synchronising the address book and the incomming, outgoing and missed calls dialing lists. Audio however works perfect now.

Does anyone know a solution to make both items working???

Thanks for your help!!!
[HD2 General] andy2111:
No, I have the same problem in my Range Rover - I can't access recent calls etc but the basic make/receive calls works OK. I have the address book already because it got transferred by my last phone.

I am hoping for better from HTC when the new 2.x firmware is released

Problem Call History in car

I have the same Problems, calling works fine but no callhistory in the car. (history was shown a few seconds an then its empty)
[HD2 General] graemenwallace:
==========================================================

Ladies & Gentlemen,

(I write this with severe man-flu! So please appreciate the effort expended!!)

Latest solution for allowing my HTC HD2 to pair with my Land Rover Freelander 2 car kit as follows by editing the phones registry:

1. Modify the HandsFree plug-in: HKLM\Software\WIDCOMM\Plugin\HandsFree

i. Change SupportedFeatures to 45 (was 1379)

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

iii. Create value HFDeviceType DWORD 2

2. Modify the WIDCOMM bluetooth general settings: HKLM\Software\WIDCOMM\BtConfig\General

i. Change bdaddr to (no value) delete the existing key value, was 00 23 76 74 2c d5

ii. Change DisableReopenAudio to 0 (default is 1) I didn't have this registry key so I created it with DWORD value 0

3. Reboot device

Now this solution has been working fine for the past few weeks, after numerous phone resets (as you do with any Microsoft device!!) and over a thousand miles with plenty of calls!!

The only downside is that there is no phone book or recent call list on the car kit - I appear not to be the only one with this problem.

Still, it is the best I have managed so far!!!!!

Therefore, if anyone can rectify this problem, please share.:D
[HD2 General] Looking Glass:
I think at the end it's the same as "rejecting" permission for the BT carkit to download your phonebook from your Leo. (I did mention a few pages ago) Problem is you have to deny the phonebook list to be transferred at every new bt "pairing" (handshaking to be more precise), that seems to be what this registry tweak gets done "automatically".

Still HTC keeps telling my to check compatibility with the "handsfree device" manufacturer.....

htc hd2 and bmw 550

my hd2 stays for hours trying to transfer the adress book... how to settle this?
[HD2 General] The_Steph:
Guys, solution posted by graemenwallace allowed me to finally being able to use my Jabra Halo as handsfree set. I am finally able to receive phone calls with it.

Thanks.

[HD2 General] Looking Glass:
Yeah, the "making-and-receiving calls" part seems mostly solved, but hang-ups and phone book transfers are out of the questions at the moment, as no solution has been posted yet, nor fixed by HTC.

Ironically my previous HD has none of these problems, So much for progress! Did you copy the message HTC?

Regards.
[HD2 General] rcs_br:
I don't know if this may help, but I tried to do the registry hack step by step to try and figure out what each change does.

One thing I noticed is that what eliminates the ability to sync the call log (volvo xc60) is the change made to the SupportedFeatures value. Unfortunately, this also seems to be the line that makes it possible to receive/make calls without having to turn off data connection.

My default value for this registry was 1379. I wonder if there is any other value other than 45, as suggested, that would enable the TP2 to achieve both the call log sync and keep the data connection on while making calls.
[HD2 General] BigBit:
I just wanted to post my problem and result. I have a 2009 Buick Enclave with built in Nav system with BT. I had been pairing it with a T-Mo Shadow with no issues. Got a T-Mo TP2 and was having issues with the BT. The device paired just fine and I could initiate calls using MS Voice Command from the phone. However, if I initiated a call from the car system, or received a call, the call would go through but neither side heard any audio.

I upgraded the TP2 to the unofficial, not yet released T-Mo TP2 WM6.5 upgrade, but the problem persisted.

I installed the registry mod outlined in post #76, and so far, all is well!

Thanks to all who helped formulate this fix!
[HD2 General] prubin:
Volvo website (www.volvocars.us) has list of supported phones and what apps they will be able to access:

Go to site, then Sales and Services and then Bluetooth.

Many of the phones will support calling, but not phone book.

Also has pairing instructions -
[HD2 General] Roger David:
Widcomm non standard bluetooth stack is the problem

I have a Jaguar XF having the same problems with the HD2:

- pairing is OK

- transfer of the phone book is OK

- after dialing a number with the display of the Jaguar it sais "dialing" even after the connection has established; due to the broken bluetooth control data connection, the call can not be ended by the Jaguar display, but only by the HD2

- during a call the connection is terminated sometimes

The here posted solution (to patch the supported features and make the Jaguar console to a normal headset) works, but is not a real solution. After all even with this patch the connections are terminated randomly.

Now I found this in two other forums:

--------------------------------------

If you remember our post about the buggy Bluetooth software HTC has decided to use on the Touch Pro2 and new HD2, you’ll remember how annoying it is. Well, now that these new devices have been available for a while, it turns out there are a lot more problems with this non-standard Bluetooth stack.

--------------------------------------

I've contacted HTC about the bluetooth issue that it doesn't allow me to use the phone with either my PC dongle or car handsfree. They first replied with the auto reply about my devices not being compatible but after I went back telling them it's a software issue due to the phone not using the standard Microsoft bluetooth stack they've now said they're going to look at getting me a fix. The problem has been reported on Pocketnow and has said it's due to the non standard bluetooth software HTC has used on both the HD2 and TP2 so I used this and hopefully they'll come back with something useful as I also mentioned the reg tweak available to show the phone as a phone rather then smartphone and they said to please not do reg tweaks as will void my warranty lol

Will let you know if they get back to me with anything useful.

--------------------------------------

After I detected the bluetooth problems I decided to try a different rom and flashed the Artemis rom (very good rom at all). But this rom also uses this non standard widcomm bluetooth stack, that causes this problems.

So we all have to wait for a HTC patch with the original Windows Mobile 6.5 standard stack or for the HD2 rom cookers to implement the Mobile 6.5 standard stack in a cooked rom.

Still broken on 1.66 ROM

I just upgraded to the new 1.66 ROM and the bluetooth problem is still there.

The good news is that the registry changes in this post still work (for me, at least)
[HD2 General] Shoggy:
A little bit off but I think most of your can help me :)

I'm planning to buy a new car radio with bluetooth. I think it will be one from Pioneers DEH-x100BT series. There is one thing I'm worrying about: I know both devices have the necessary profiles but will I be able to stream audio from the HD2 to the radio AND will the headset function work at the same time?

When I get a call I would expect the music to stop and I can answer the call through the radio (car speakers + external mic from radio). Right or not?

[HD2 General] FrankCastle:
i have the problem in which when i originally pair up my HD2 to my Eclipse 3200 stereo, hands free through the stereo works fine.

But once i turn the car off, then start it again - the 3200 and my HD2 will only pair the sound streaming portion of my phone - not the hands free part

i have tried applying the registry entries as detailed by graemenwallace but i still get the same result! :( I know its not my stereo as my previous phone (HTC 3600i, stock rom WinMo6) paired up fine each time i turned the car on

i am currently running the 1.66 stock Rom for my HD2

any help would be greatly appreciated
[HD2 General] busspass:
Not sure if I've cracked this...

I've been having fun and games conecting a BT head set but found this...

Once you have established a connection, on the HD2 you have a screen showing all connected devices - the screen has 3 tabs acrossthe top with a graphics showing setings, devices, and options - or something like that, with the middle tab selected. Your recently paired device should be listed. Select your device and then tap on "properties" at the bottom of the screen on the soft menu bar. Tap on "Conections authorised". Your BT device wil now be allowed to connect next time you need it to.

Hope this helps

Hi all

I have the same issue with my Volvo C30 bluetooth. I also went to update my car's internal bluetooth driver. No change I have the same problem. Can't wait HTC to solve this issue by realeasing a fixing cab or an update of the ROM.

Best.

My Toyota Avensis with Premium Audio system perfectly handle with a2dp stereo music transfer and headset function same time.. :)

Yes, when the call initiated a2dp bluetooth music transfer paused then start after conversation... Also track seeking, track change, track information with integrated car audio system is working flawless... :D

Thanks God for HD2 bluetooth work perfectly on my car.. :) Otherwise i'm afraid impossible to use my HD2 in my car because of well known bluetooth headset voice dialing issue... :eek:

Does anyone found that the problem has been solved with the new official 1.66 rom?
[HD2 General] omneity:
I can now make/receive calls via Bluetooth, I don't use the phonebook option as I have over 800 contacts so it's easier for me to use the native phone interface. Previously I could usually make calls, but it would answer incoming calls but no sound would work.

If you're having issues I would definitely recommend you upgrade your ROM to 1.66.
[HD2 General] Fall Guy:
I have the new ROM but still have issues with my 09 Ford bluetooth radio. It works only if the audio streaming option is activated. Which does mean that I can`t use the line-in option to play music and it doesn`t have a bluetooth streaming channel on the unit. It does however make calls and download the phonebook.
[HD2 General] afekhad:
I confirm that it still does not work: pairing OK, audio NONE...

HTC please take into consideration this issue!

[HD2 General] mjsmith:
rSAP and VW Phaeton

I am having a similar problem with my HD2 and the Premium Phone kit in my Phaeton. The first time you create the pairing everything works fine. rSAP kicks in and takes over the sim, the 900 contacts in the phone book download to the car and I can send and recieve calls. All is well until I turn off the ignition, the next time I turn it back on, the car tries to connect, rsap kicks in for about 5 secs then it drops out again. If I leave it, the car will keep repeating this process of connecting and droping out until I manually cancel the connection. The only way to get it to work again is to delete the pairing from the phone and the car and start all over again. Great until you turn the ignition off and it all fails again!!!

I suspect the problem lies not with rsap but with the Phone Book Access Profile (PBAP). If you watch the process in the Bluetooth screen on the phone, in the initial pairing both rSAP and PBAP both appear. However in all subsequent attempts to connect, rSAP appears but PBAP only occasionally appears and when it does it quickly vanishes again, but most of the time it does not appear at all. This probably explains why the phone works after the registry changes described in earler post where the phonebook does not download.

I have logged this with HTC support today and will see what they come back with
[HD2 General] wonderstoat:
Only syncs when unlocked

I've found a way to pair my HD2 ok with my Audi A5, but the phone has to be awake and unlocked for about 3-5 mins for the phonebook to resync (it does it at every handshake) and for the call history to also "upload" to the car. I realise that this probably sounds pretty good to the rest of you having bigger issues ...

But I wonder if there's any workaround or regedit that I can do so that the phone doesn't need to be awake for the handshake to happen properly. I can't understand why they would do that ... no WM phone I have ever had before (Tytn, TYtn II, Diamond, Diamond2) has ever needed to be unlocked to sync. I use phoneweaver to auto turn on BT every morning and evening for the ride into work ... this makes a bit of a mockery of it! LOL

Just wondering if anyone has any ideas ...

I am on the 1.66 rom.
[HD2 General] djcentrino:
I had problems trying to connect my HD2 to my Kenwood 5220BT. It keeps dropping the music connection, so i have to manually connect it each time, and when it is connected it is of poor quality.

But the main problem was that i could not start a successful call from the head unit itself. It was as if the head unit had dialled the number but the HD2 was not ready. If i dial out from the hand set the hands free worked fine.

GOOD news since the latest ROM update (1.66.405.2 (76641) WWE it has been working fine dialling from head unit!!

I will give the music over bluetooth another try - i remember seeing a thread which showed how to up the quality over bluetooth.:)

Indeed, the HD2 paring with succes with the car but after a few minutes the phone signal is lost and i mus restart the phone and reconnect but after few minute it does the same thing again and again.

Before i was using a HTC P3300 with this device and it works perfect.

How could we back to the original bluetooth stack ???
