Hi,
I have problems connecting to my bt headset since I have installed TomTom3. I am running the build3500 bluetooth stack from the 1.06.02 FRA radio. It was working fine without even losing connection with the mda, but after I installed tomtom, it can pair, but cannot connect. The weird thing is that I can sync using bluetooth. I suspect tomtom is keeping busy some of the bt com ports? i noticed that during installation, it required to close bluetooth (cause it said the file BtcoreIf.dll was in use) and as soon as I did that, it finished installation, but since then the headset stopped working. Anyone has similar problems??
Thanks in advance for any input.
Update
Managed to sort it out by upgrading my BT stack to 1.0.0.3900. Still cannot find any similar complaints in any forums. Can it just happen to my MDA III? Who knows....at least it works now, even if my engineering background is not happy with it :shock:
Upgrading the bluetooth stack
Hi,
I have exactly the same problem as you had, although I'm on the UK network Vodafone and have an XDA2s.
My current radio version is 1.06.02 but I can't fine what version my bluetooth stack is. How do I upgrade to 1.0.0.3900?
Thanks in advance for any assistance you can provide.
Hi,
I am using Qtek9090 with TomTom 3.07 and Jabra BT800 headset and have not the problems you people talk about here. I have to mention that I immediately updated my BT version from 2400 to 3900 the same day I purchased the whole stuff. I was - when I was in the shop - told that TomTom 3.07 can sometimes cause problems due to BT version of Qtek (1.0.0.2400) and I better upgrade it to 3500 and/or 3900. I was also told that there were known problems with earlier versions of TomTom wireless (like in your case TomTom 3.03) and that I (at least) had to use TT 3.07 and/or better upgrade the BT driver of my Qtek9090. In order to find your current BT version:
- Click on Bluetooth icon
- Select Bluetooth Settings
- Go to [About] tab
- And there you see your own Build
- You can also select [Advanced] button in [About] for more details
Anyway, once being at home and taking my device out of package I did a BT upgrade to 1.0.0.3900 right away and so far I have no issue with BT stack. Even Jabra BT800 which a lot people complain about works fine with my Qtek9090 (OK, I admit the CallerID at Jabra still not working but I already expected that).
I downloaded the 3900 version of Bluetooth driver (plus another Audio driver) at the following URL in The Netherlands: http://www.pdanieuws.nl/modules/mydownloads/singlefile.php?lid=37

tomtom gps
The problem is that tomtom is messing around a bit with bluetooth for bt gps receivers.
So after installing tomtom allways reinstall the latest bt drivers.
AFAIK you should always use TTN 3.07 (GPS and Navigator) on SE and Phone Edition devices (Blue Angels is both WM2003SE and Phone Edition)
Big Fat TY
I was getting stupid before reading this 3d.
Even went back to the shop with the motorola headset and had them show me it was working....
Tom Tom was the reason.

Hi,
On the Dutch web site of PDANews there is a bluetooth patch available since while ago. As the topic says Arne Hess has delivered a patch for bluetooth problem of i-mate PDA2K which also works on XDAIII/Qtek9090. This patch obviously solves the problem many users have been complaining/asking about, namely listening to music through bluetooth headset. It also offers support for bluetooth keyboard to work with Qtek 9090.

(To download the patch just click on the floppy icon which is a link to:

I was just wondering if anyone has tested this one and can share his/her experiences with other users.
kind regards,

By the way, the patch I was talking about is also available for various languages at the web site of Dangaard (AFAIK Dangaard is the distributor of HTC stuff in The Netherlands) :

The original oem_wwe_124_008.sa.cab have been around for a while.
I downloaded the one from your link with the same name as the original oem_wwe_124_008.sa.cab (Stupid not to rename it) and it seems that there is some 25 more files in this one.
Just do a backup of your device, install it, test it, if you dont like it, Hard Reset and run a Restore.
Sprite Backup can help you with this.
Post your experince with it.
And the .cab file on http://www.dangaard.com/qtek 9090 bluetooth patch/ is not the same as the one on http://www.pdanieuws.nl
Like i said, Stupid not to rename it
Just wanted to hear if this patch works..
I've been reading lots of forum posts with people talking about the problem in the Microsoft BT Stack, but does this patch fix the issue?
Im dying to get my music out of my bluetooth headset..
i got i can no longer use the Bluetooth because of the lisense issue
so i just reinstalled BT3500 and it worked (not the patch)
vbguru613:
I guess you are talking about basic Bluetooth functionality. I have that working. What I need is to be able to listen music on my bluetooth headset.
I upgraded to the Qtek rom without any hassle at all (over the top of the i-Mate 1.30.82 latest offering with v0.60 bootloader) and find that it now pairs fine with my bluetake iPhono BT420EX and now offers "Wireless stereo" service in addition to "Hands Free"... but it doesn't work!
HELP - I feel I've come so close, but must be doing something wrong...
If I enable A2DP output by long-click on the iPHONO PLUS and selecting "Set as wireless stereo" (is there an easier way to initiate this?) I hear sounds from all the events, but 'stuttered'. Playback sound via TCPMP or Media Player and it is slow and stuttered. It is as if something has grabbed all the CPU and causing everything to respons slowly. I've got things like PocketBreeze installed but thats about all! Nothing is shoing on the running taks.
On the Hands free side, it has never worked. The phone ignores the headset (and did so on the previous iMate release). The JasJar works fine with my SE HBH600, and the IPhono works fine with my Wife's Samsung D500 so I don't understand what is going wrong here.
Has anyone else come across such problems, or can suggest where I can look for answers.
I have tried a cold reboot to clear any installed progams and it still does the above.
Any help would be really appreciated
Cheers, BossHogg.
RE
There's a 'A2DP Lag' patch somewhere on this board. Do a search, install and see whether it solves your problem
It might be an issue with headset compatibility. I have a Motorola HT820 and I don't experience any stuttering or loss of sound unless I am too far from my Universal.
Can someone do me a HUGE favor? I'm trying to get the X-Scale AKU2 AD2P files for the Treo 700w. From my quick reading of the rom decrypting threads, I need a HTC Uni device to compare the "merged" data from the update + original rom...which I only have a Treo 700w.
I need the following files: Avrcp_MPplugin.dll, bta2dp.dll, sbc.dll
The theory I'm testing is by using the Intel X-Scale compiled files instead of the OMAP compiled files (it appears the file sizes are different on each platform), the Treo 700w will be able to play files without skipping. A poster on pdaphonehome.com suggested this discrepancy.
FYI - I have already tried the AD2P lag patch thread priority patch to no avail.

Qtek Rom is one of the worst rom that i have used till now. A2DP is fancy feature even though i have applied the A2DP patch it was good for some time. After reset of my DOPOD 900 it never worked. I suggest use the recent DOPOD 900 1.30.111 on Uploads folder i can tell you it is one of the best roms that is used from stability point of view. Do not use Radio 1.11 as a.06 is the best. Cheers

It is NOT a fancy feature and, also, because you're not using a QTEK 9000
FYI, I'm using the QTEK 9000 + the latest ROM update + the A2DP lag patch with my iPHONO mini 450Rx and everything works fine

I don't know what version of the QTEK ROM are you referring. But I am using the QTEK ROM version 1.30.77 WWE with A2DP and AKU2 and I have not encountered any stability issues. Plus I never had problems with A2DP even without the patch. Works great on my Motorola HT820.
Spread the love to the Treo 700w users...we need x-scale a2dp DLLs, not the TI OMAP compiled ones for the torndado.

RE
taurus_bull2005
QTEK 9000 ROM update has only one version (the one you're showing) unless somebody changes the EXTROM or upgrade/downgrade the radio.
One thing to note. If you're not using a QTEK 9000 but another Universal variant like JJ/O2 EXEC/Dopod 900 etc things may not work out ideally since the update is customized to QTEK 9000.
If if works, then its a bonus. Otherwise you just have to accept some hiccups in the use of other maker's ROM. This also applies to say using Dopod 900 ROM on my QTEK 9000 or JJ ROM on Dopod 900 etc
I suspect the QTEK ROM don't work well on your machine and its affecting the A2DP and probably giving you those mentioned problems.
This you can test out by hard resetting your device and test the default programs to see whether the mentioned problems exist. Then test the A2DP WITHOUT other programs installed. If it doesn't work then there's a compatibility issue between the QTEK ROM and your machine. If it works fine then it must be some programs you installed thats causing the problem. Forget about the previous 'work fine' applications with your iMate ROM
RE
taurus_bull2005
Just another thought. Could it be your ROM is corrupted?
Can you re-download and re-flash again?

Hi guys,
this morning I've found the firmware upgrade for Jabra BT620s. It solves all connection problems (no need to activate AD2P from Bluetooth Settings Applet) and improve quality.
Here the link.
http://www.jabra.com/JabraCMS/EM/EN/Misc/Software620s (server is very slow)
I hope this is a real news... I don't know when the update became available...
ByezZ
it's available now and i downloaded it on my BT620s
i feel the quality is better now
what is the best bluetooth headset for dopod 900?thanks
Wau
Wau this update is cool. I was happy with the old one but this rocks ) thnx for info .. I didnt know that it is possible to update firmware in my headset ...
Can you use the sync cable that came with your PPC or do you have to use one provided by Jabra?(If there is one?)

I think that a normal USB cable like the Universal one is required... But not completely sure... If Windows installed the driver without problems, everything should be ok... Let us know!
Nice. By the way, this update doesn't work with Windows 2003 x64. I don't know if it x64 or 2003 issue
Had to patch it on winXP

Could anybody upload this update somewhere else?
Here you go:

Thanxxxx!!!
My apologies for posting so long after this thread died down, but I have a few people to thank and it is well earned credit regardless of how far after the fact it is given. To edeplano and marco.minetti for their posts about new firmware for the Jabra BT620s I am most grateful as it was the key to ending my troubles with this headset, and a special thanks to captainsensible2002 for the rapidshare link since the original link has gone down.
I can't tell you how deep a hole I've dug to find an answer to this headset's problem. When connecting my AT&T Tilt (HTC TyTn II), if I don't turn on the phone's BT radio first (as opposed to turning on the headphones first), I have to go through all those "activate AD2P from Bluetooth Settings Applet" steps. My original thought was to find a macro program to record all the steps and just link that to a hard key, which is when I stumbled on edeplano's post. After a bit more digging through Google to find out more about this new firmware, I got linked back to this thread. Thanks to you guys, I needn't worry about any of that "which BT is turned on first" nonsense anymore as the headphones connect regardless of which device is switched on first now. I haven't tested it for better quality yet as has been claimed, but I thank you all in advance if that is truly the case as well.
problem updating
Hello! I'm a new user of the Jabra Bt620s. I was trying to update the firmware but once i put the headphones y "software download mode" windows asked me for the driver but... it has no drivers! and the program SATURN don't want to give me the "NEXT" as an option.
Have anyone experienced this problem?
I've tryed to update the firmware in windows XP SP2, XP SP3 and Vista Ultimate.
PLEASE! HELP!! thanks
I too am having this problem. Is there not a driver? I have spent countless hours over the past couple weeks trying to find this stupid driver... it is like it doesn't exist!
No luck for me
Apologies for resurrecting this old, old thread. I'm stuck, and don't know where else to turn.
I bought a BT620S on ebay. It seems like a great device, but I would like to update the firmware to address some of the stuttering, etc.
I downloaded the firmware update software and ran it. I plugged in my headset and pushed the two buttons, until one of the lights changed to green. However, the firmware update software just sits there, with the Next button disabled.
Does anyone have an idea about how to update the firmware successfully?
im having the same issue has everybody else.. next button does not work
Lolz, this was an year old thread & I just thought we have something new. I bought BT620 after this date so my BT may already have this.
I also was annoyed by some of the small issues with the Jabra BT620s, and also found the jabra.com webpage useless for firmware update, and also found this thread.
Next never became avaiable in Win7 64 bit (not even in compabilitymode), but then I turned to my girlfriends old laptop with WinXP 32bit (all updates installed).
Here no problems were encountered, everything went according to installation instructions, and the update seems to have helped on the sound quality ecc.
Thank you so much for providing the link! I hope this can help someone else.
Got it!
6 computers in the house, but no Windows XP.
Visiting in-laws for the holidays, and they have only WinXP. I brought the firmware upgrade .exe and the headphones, and it worked. Awesome!
The sound sync isn't quite perfect: when I play Left 4 Dead, firing weapon the sound is a little late. But for anything else, it seems just fine.
Thanks folks.
I just upgraded my bt with this & now there is no A2dp support. Can anyone point me towards any other update? I need to rectify this as soon as possible.
Nightmare!

A few days ago I upgraded my HTC P3300 to the official WM6 rom.
All works fine except calling using my bluetooth carkitt.
The carkitt I have is the factory carkitt in a Peugeot 307SW. I've read somewhere this carkit is made by Parrot and can also be found in the Peugeot 207, Citroen C4 end some Seat models. Googling showed averyone with those carkitt's has the same problem sinde the upgrade to WM6. It all worked fine in WM5 by the way. I've also tested with several non official WM6 roms, but it's still not working.
Connection and pairing the phone is not the problem. I do see the contact list in my car display and I can even see the battery status. The problem is when I dail. My speakers mute my radio/cd sound, but I don't hear the phone through them. It's just silent. I can't hear the person answering the phone and I don't hear the dial tone. The strange thing it sometimes works. I have the impression it starts to work after I strated tomtom, but I'm not sure about it. What never works is when people call me. The phone rings, but when I answer I can't hear the person on the other side.
Is there any way to fix this? It looks like bluetooth 2.0 isn't 100% compatible with bluetooth 1.1 or it's a bug in WM6. There is no upgraded firmware for my carkitt available and like saif before, a lot of other car owners have the same problem.
Please help.

I'm stuck with the very same problem. I'll try JetWare and change some configs, but I fear it will not work.
If I have any news I'll post them.

Has anyone found a solution for this? I have found deactivating the bluetooth and reactivating on the call works.
I would hope someone finds a solution. What would be the downside of going back to WM5?? I cannot remember why I upgraded now.....
I finally downgraded to WM5, but I'm interested in knowing if new WM6.1 ROMs have corrected the problem. We have both Blak&Blue and Vanilla versions based on WM 6.1
I've not upgraded to WM6.1 because I'm tired of problems. If someone try to install it, please report

Mine is an HTC P3300 locked to local Movistar provider. To downgrade, you must find a WM5 ROM, that's all. I found ART_HTCESN_1.14.412.1_026790_ESN_Ship.exe but it is Spanish, so probably it doesn't interest you.
Downgrade procedure was exactly the same as upgrade.
Would you be so kind to test some WM 6.1 releases with the car's bluetooth before downgrading to WM5?. It could work and I assume that in any case you are going to reinstall everything, so a kick install should be not much of a problem.

Nice!
But I find a problem, isn't your O2-XDA also known as Wallaby? I mean, if I'm right you are posting in the wrong forum or at least you should be advised not to install another PDA ROM on yours becouse you risk to brick it. We are posting at Artemis forum. Of course, Bluetooth problem seems not related to PDAs but WM6
On this forum there is info about how to unlock your PDA. Unfortunately I dont find any ROM for your device.

Same Problem
hi all,
207 FACTORY KIT / M650
I have the same problem, only the original ROM under WM5 work properly...
I Tried many bluetooth soft on several tips and WM6 release...
AJE , 1.5 / 6 /8 / 9 / 2.0 beta........
Now i am under B&B 5 (WM6.1) and the problem persist
I note that if i desactivate bluetooth stereo and fix sample rate to 44Khz, it looks to work a little better than before.
If i wait between 2 phone call (out), it works much.
If i answer to a phone call with the remote control it never works.
If i answer with green touch on the phone it work ALL the time.
Are we condamned to stay under WM5 !??
WM5 -> bluetooth but no CRM (does'n't want to work)
WM6 -> No bluetooth but CRM...
I choose to work on this but any result, since more than eight month...
HEEEEEEEEEEELLLP US AND SHAME ON PA**OT
PS: HTC and parrot pass a deal to increase compatibility of their product...
Since this time does anybody tel to parrot on this problem ?
Does newer HTC product originaly under WM6 work fine one factory kit (peugeot/citröen 207/C3...) because if no, i think parrot sucks ! they update firmware on all their product, but for product sells to peugeot or citroen -> NOTHING
Thx for the info. It's a pity that the problem persist on WM6.1
We are hooked to WM5 and to my eyes, the Artemis and PocketPCs look older than ever.
At the end, I think it is a Microsoft problem. PSA Bluetooth CarKit works flawlessly with WM5 so Microsoft changed something to the Bluetooth stack on WM6. Shame on them.
I'll wait to WM7, but I don't have too much expectations.
Regards
Some hotfixes are available from HTC regarding bluetooh, only not for the Hermes. damm.
Anyone tried one of these already? Currently still not able to updrade to WM6.1
