WM6, bluetooth car kit and incoming port problem

Hi guys,
I am at the end of my tether... I just bought a JVC head unit with on board bluetooth, so I can use it as a car kit. But I can't get my Treo 750 to pair with it! It just locks up after I enter the passkey... and the car kit just says "error" after a certain amount of time. I'm running a vanilla (extended ROM removed) version of the 3 Australia ROM.
So, I rolled back to Windows Mobile 5... same problem... UNTIL I went into the Bluetooth settings and setup an incoming COM port. Then it paired up perfectly and all was well.
So I've reinstalled WM6, but it doesn't have the option to create an incoming COM port. That's really annoying. I've googled a heap, and searched these forums a fair bit too, but haven't been able to find any sort of workaround. Is there a registry hack, third party program, or some other way I can tell it to allow an incoming connection from the car kit?
Thanks in advance!

Has anyone had any ideas on this? I have a real issue now, as I rolled back to a WM5 ROM which I found on these forums but I'm having awful problems with it - it drops calls all the time and sometimes they just go silent..... the call stays connected but I can't hear the person on the other end.
I really need to get either the original Telstra WM5 ROM, or a way of getting WM6 to work with my car kit! Any ideas... anyone??

Okay... now I really feel like I'm talking to myself but anyway.... thought I'd give an update.
After heaps of trial and error, I managed to install the Universal version of the Broadcomm bluetooth stack onto my device. And it pairs - hooray!
However... when I make a call, no sound comes through the speakers
No other version of the Broadcomm stack will run on my Treo, I just get the memory error that lots of other people have mentioned.
Chalk another person down who's royally annoyed with Palm for putting such a dodgy implementation of Bluetooth into these devices. It's my one and only bugbear to date.

I have exactly the same problem when pairing my WM6 Treo 750 to a Parrot MK6100 carkit. After entering the passcode on the Treo, the device just hangs. The carkit says it has connected succesfully, but nothing happens. After restarting it does not recognize the carkit at all.
Did you find a solution yet? I am also looking for a different Bluetooth stack that is guaranteed to work with the Treo.

Good to see I'm not the only one. No, I haven't found a solution yet unfortunately
The closest I've come is that hacked Broadcomm Bluetooth stack. My only hope is that some nice developer will help us develop something that works!

Hi Ben,
I solved my problem yesterday. I tried two suggestions.
1) Leave the passcode field blank (do not enter '0000') and press next
2) Install http://www.jetwaremobile.nl (fully functional 30-day trial)
After that pairing succeeded in a couple of seconds and all is working well. Let me know how it works out.

Thanks very much MattMax!
I had tried the Jetware software previously, and it didn't help. But I hadn't tried leaving the passkey field blank. Did that this morning... it popped up with a connection dialog asking if I wanted to allow the connection... went back to the passkey screen, I entered 0000 and away the sucker went. How simple was that!!
I just upgraded to the latest ROW2.23 WM6 ROM the other day, so I'm not sure if that made any difference either. But it's now paired and (seems to be) working well, just need to make and receive a few calls to make sure.
Thanks very much for your suggestion!

Good to hear that it worked out!
I had exactly the same experience, leaving the field blank, after that entering '0000' and it worked. I had just installed Jetware Mobile, but apparently that is not necessary for the solution.

Bluetooth Handsfree on MEX-BT2500 - Incoming Calls don't Work

I have an MDA Vario III branded phone using the HTC ROM 1.56.405.5 and a sony MEX-BT2500 (Bluetooth enabled stereo with A2DP).
http://www.audio66.com/product.asp?id=5616&cat=1&man=6&main=1&userid=&firstsel=cat&variation=
The A2DP works well (except it's a pain to enable/disable it using the WM6 interface!) and I can make outgoing calls fine with the phone paired with the Sony but when incoming calls come in, the ringer is routed to the stereo but when I answer it the voice doesn't and I have to hang up and call the person back.
I paired my work Nokia with the stereo and both incoming and outgoing calls work fine.
I tried the original T-Mobile ROM and still had the same trouble.
I'm assuming (with no knowledge of what I am talking about) that the bluetooth stack on WM6 has some issue with routing incoming calls but I can't find any reference to this problem anywhere else and it would seem to be the kind of problem I'd expect millions of users to have a problem with and that there would be a lot of posts.
Does anyone else use bluetooth handsfree? Does it work properly? Does anyone use a bluetooth stereo and A2DP? Does it work properly? Does anyone know if there's a fix?
Thanks for the info in advance...

mine works Ok with my BT2500 although sometimes it needs to be re-paired

Info
Can you tell me what ROM version you have and what model your phone is, radio version, installed programs etc? so I can try changing things.
If you hae a2dp music being streamed and a call comes in does it still work?

ROM is UK Vodafone out-of-the box original (v1615 = Tytn II) 1.56.161.4
Radio is 1.27.12.11
Have Seuth255's A2DPFix from the Hermes forums (prevents skipping)
MS Voice Command V1.6 (i have a SE BT headset too)
Remainder are general apps, gps etc.
haven't tried a call when music is streaming. will do later and let you know

Works for me too, with the original HTC ROM.

Everything is working fine here. I have a MEX-BT2507X, and there's some random 0.2sec cut every 15mins of playtime, but that's not a problem.
Have you used the quickfix from HTC?

I didn't know about the HTC Quickfix. I've just downloaded it and installed but haven't got round to leaving the PC to test it yet. I'll give it a go later and post back.
Fingers crossed...

Audio not working
My audio is not playing through the car speakers with the BT-2500. I had it professionally installed, but was running late to class so I didn´t fully test it until I got home a few hours ago.
I can control the tracks and play/pause, accept/end calls, and the dash microphone works, but my audio is not being pushed and played for some some reason (does work for CD, and Radio). I tried repairing numerous times, resets, and different programs, but no luck... but audio push worked great on a handsfree kit.
any ideas are greatly appreciate... I will take this back to the shop tomorrow, but I would like to know if anybody else experienced this and how they fixed it.
Thanks!! =)
btw, I use stock AT&T rom

...much, much later...
I finally got round to trying it out and even with the quickfix I still have the same problem. My mate also has a Kaiser so I borrowed that (UK O2 ROM I think) and that doesn't work either.
Most odd. maybe I'll ring Sony.

I have the same problem with my Jabra 620s. Maybe somethings wrong with the headset itself?

Can you let me know ur ROM, radio versions so I can see if we have anything the same.

Bluetooth stops/crashes when connected to Car kit

Hi,
When my phone is connected to my car kit (Opel/Vauxhaul UHP) bluetooth sometimes stops randomly. I can turn bluetooth on again with the commmanager and everything is working again. But it can hapen again after a few minutes.
Does anyone have this problem to or even better a solution?
I allready tried all the different Radio Roms, but this didn't solve my problem.

Well with mine i have some hickus but it just happpends once a while.
Most irritating about Diamond and BT in my opinion is that wa have no equalizing for it. and the sound setup from the begining is horrible.
Asked here if anyone has a solution before but none replied.
But as far 2 your problem no. And i use a Pioneer system in my car.

I've a JVC head and my bluetooth has no problem.

I have a Honda Accord with handsfree built in and I too am having problems. The phone and car both agree that a connection has been made but when i use it to either ring out or receive a call the radio mutes and when receiving the ringing tone sounds over the car speakers but I can`t hear the caller except on the phone which isn`t very useful. Would a ROM or radio upgrade help or is it just a compatibility problem

I had this kind of problems also. Also syncing the phonebook gave me problems. You could try JETware, this solved almost all my problems, except now the bluetooth crashes

Thanks Mauser. I tried Jetware as you suggest and I`m afraid it didn`t help in fact I think it crashed the handsfree system in the car like you. This is the final nail in the coffin for my Diamond. I just can`t get used to it so it`s off to Ebay with it.

I'm sorry to hear that
I am very pleased with my Diamond... I would sooner put my car on eBay than my Diamond
Did you try to check almost everything on in the advanced settings of Jetware? I have also limited the phonebook sync to max 5 entries to debug and on the site of Jetware there wat a fix for Opel car kits.
Keeping my fingers crossed, but until now I haven't experienced any bluetooth crashes.

Thanks again Mauser. I tried various settings but without any success, I think the phone is just not compatible with the Honda. Having said that I don`t have much luck with bluetooth at all on the phone. More often than not It just won`t detect other bluetooth devices and when it does it won`t send or receive files so it`s time for it to go and I can go back to a trusty Nokia

Problems here with BT connection to car kit, too. I'm using the built-in car-kit of an Audi A4 (standard one not that with navigation, remote SIM, etc). I've noticed the following issues:
- when I try to make a call, the CD is cut off but NOTHING is heard in the car speakers UNTIL the other party answers the call (and then I start the conversation). No ringing tone, no nothing. I cannot hear the busy tone, or network failure/congestion tone and this is annoying since I have to keep an eye on the phone to see what's happening. I found myself checking the phone when, after calling someone, nothing happened and in fact I got a busy tone and the call ended.
- sometimes, when I receive a call, the CD stops playing but when I answer nothing is heard from the car speakers but only from the phone (as davemazo said also).
- when I receive a call, I hear in the car speakers a "standard" calling tone, not the ringtone I have assigned for that contact
I have to mention that with any Nokia I had before (and still have one as a second phone), these problems do not exist. I know there is a compatibility between Audi factory installed car-kits and Nokia, but BT is a standard and most of the functions should be supported despite the phone model/type. I've tried also with an iPhone and it's working great, as my Nokia do. I don't understand why it is like this with the Diamond. In fact, I think it is not related to Diamond itself...it's doing like this with ANY Windows Mobile device I've tried in the past (Orange C600, Samsung I600).
Are there any solutions for this? A CAB, a new BT radio, a software, anything?... I don't want to buy a new BT car-kit and try with different models until I find something compatible
Thank you for any info/tip

Hi Rapier,
I also had a SPV C500, MDA Compact, Qtek 8500, Samsung I600, HTC Touch Dual and now the Diamond. The only one which gave me no troubles was the SPV C500, but I think that was because this phone didn't support phonebook synchronization and had no network identification/signal strength over bluetooth.
After the SPV C500 it went wrong. First I noticed that after a hard reset it worked for a few days. Later (about 2 years later ) I found out that it was because the call history was going to long to sync over bluetooth.
Then I found Jetware in which you can limit syncing to any number of items. They even had a fix for the connection to my carkit.
Unit now... it works like a charm... but keep my fingers crossed
I don't know if your carkit is a Audi UHV, but I saw that they had a fix for that too! You have to just install Jetware and then run the fix-file from your phone. Good luck!!
P.S. I am in no kind related to Jetware, I just found out that it worked for me.

Yes, I have an Audi UHV 6634. Thank you for the info, I'll try that and post the results here. Though, my car-kit is not the advanced one and I don't have to sync anything with it (contacts or something else). It's most working as a plain hands-free device, no extra functions...speaking of which, I've noticed that on the phone is detected as "hands-free"...why not "car-kit" as I know a car-kit has other functionality as well? This is the "standard" BT device for any audio enhancements (even if it is a car-kit not a BT headset), or I have to activate something to be recognized as car-kit?

my Honda system doesn`t read the sim I can only dial out via handsfree using contacts i`ve entered into the Honda system otherwise I either have to read the number to the system and it will ring out (most of the time anyway) or make the call on the phone (illegally obviously) cancel the call and then say "redial" and the system makes the call. So uless I`m misunderstanding this setting I don`t think it will help me.
I`ve searched the Jetware website and I couldn`t find a fix for my Honda

UPDATE: So...I've downloaded it, install it on my Diamond (including the extension file for Audi UHV) and...no change. Everything as before with both issues. Disappointed, I've uninstalled Jetware then...surprise. AFTER uninstall, I can now hear through my car's speakers the ID ringtone Maybe some BT settings were altered and remained like this after uninstall, but I don't know why it didn't work when Jetware WAS installed...strange.
Anyway, many thanks...at least half of the problems are now solved and this only by install/uninstall a program...that's cool. I must now find a way to make the car kit ring when I make a call, this is still an issue.
P.S. I've seen that Diamond support Headset and Handsfree profiles...and when connected to my car kit is set as Handsfree. I suppose this is better than Headset...but still no ring out tone.

Hello,
I have a Mercedes car kit and facing the same issue as you: everything works perfectly for a few days when hard-resetting my device, even with my 500+ contacts (they are loaded in less than a minute), but after a few days/weeks I can't get to have my call history or contacts displayed in less than half an hour!
Yesterday I thought I'd just hard reset my device because I had this problem again, but unfortunately it didn't work!
Guess what I have done differently this time: yes, I backed up and restored my call history, which I hadn't done the previous times! So I guess it is indeed related to the call history, but I can't test for now!
I have installed JetWare and limited the call history to 5 numbers, I'll try this tonight and I'll keep you informed...

Hello,
So I have tested this yesterday (installed Jetware and limited the call history to 5 numbers), and now it works FLAWLESSLY! I can browse through my 500 contacts instantaneously when I pair my phone with my Mercedes car kit.
So, in my case it was also clearly the CALL HISTORY that was causing problems... A BIG BIG thanks to Mauser for pointing out this!

I'm also having problem connecting my Diamond to my Volvo S80. All the other functions work except that I could not hear the other party through my car stereo and I also could not diconnect the call with my car end key.
I'll try the Jetware and I'll report back later. Thanks for the pointer.

Touch Pro and Passat Premium Bluetooth

Hi there,
maybe anyone got an idea. When trying to Connect my Touch Pro to Bluetooth Radio, it works for the frist time. Next time i get in my Car it tries again and again to establish a connection but it doesn´t work.
Maybe someone can help me.
Dolphus

Just look at the thread started by mstaxin. That will explain a lot.
I also have big problems with the bluetooth connection in combination with my carkit (just for the record I also drive a Passat but that hasn't got anything to do with it). First I had a Parrot CK 3100 and worked great with my TyTn. The Bury CC 9060 should work better with the Pro, and it really works a little better. But after every call the connection is gone. So far it seems there is nog good device to connect to with bluetooth in any car.......
Now waiting for a promissed firmware update by Bury. Wish you luck.....

I think I fixed it!
I was having a problem not unlike yours, where I pair it the first time, and all is well, and the next time it doesn't do anything. I fiddled with my car's bluetooth (BMW ULF), and a headset and they would connect, after fiddling, but just not on startup. I finally determined that it appeared that the phone was not setting up a keepalive with the paired object. I found two reg keys in the bluetooth stack that were relevant. I changed them, and it now works exactly as you would expect every time!
Keys:
HKLM/Software/Microsoft/Bluetooth/Audiogateway
ConnectHFOnCall=0
The default is 1, which instructs to only connect on a call
PowerSave=0
The default is also 1, but this makes bluetooth be "awake" all the time
Change the settings, soft boot and you shoudl be good to go!
Hope that helps

Diamond and car audionavigation JVC NX7000 bluetooth problem

Hi all,
Need help with my HTC Diamond. As my Pioneer car navigation, with which the diamond bluetooth functioned well, was stolen, I was advised to mount a JVC navigation system NX7000 with a detachable front in order to prevent theft. However, the HTC bluetooth dysfunctions. It connects and pairs without problems, but when the diamond goes into sleep or is switched off, it is impossible to establish a phonecall using the JVC car-unit, although it indicates that blueconnection is still valid. When I switch on the phone, even minutes later, it will eventually do the call. If I force the HTC to remain powered-on it will function normally. I am sure that this has something to do with a suspend-mode of the diamond bluetooth part and that this can be solved by the right registry tweak. I tried several tweaks that I found on the forum already but without succes. I upgraded the HTC to the latest firmware 2.03 but no improvement.
I called with HTC and they said that they know the correct registrysettings but they won't supply them because of "licence restrictions"...........
Anybody the same problem? Somebody who has the solution?
Thanks

I have exactly the same problem! Incoming calls work fine, but like you, I cannot initiate outgoing calls from the JVC unit unless the diamond is turned on fully. I there's not a fix for this, I may have to go out and buy an iphone again after selling mine to get a diamond!

there is a fix but HTC won't tell. they suggested to open a thread on this forum in order to get suggestions on the matter. and so I did. When I subsequently asked them if they would post this solution on this forum they said they would not :-(

You may not want to fall back on an iPhone with the JVC NX7000. Not to go too far off-topic here, but pairing an single iPhone works great (once I figured out the overly complicated menus). BUT...it won't let me pair a second phone (of any kind). Once the first phone is paired, all pairing menu options are greyed out ("Search" and "Open"), thereby preventing any further phones from being paired. I first need to unpair the first phone before I can pair the second one. JVC Support is comically unhelpful.
Has anyone had luck paring more than 1 phone (of any brand) with the JVC NX7000?

You are the lucky one! You can succesfully pair one phone but it works

I don't care if I can only pair one phone. I only have one phone! lol.

Hey guys!
kind of the same problem here but with the Volvo built-in bluetooth solution. Actually when the device sleeps and I initiate a call it will take some time, then the device will turn on and it will begin to dial but drops immediately. When the device is fully turned on there is no problem at all. Incoming calls work just fine. Even though it first rings on the phone and after a second or two it will ring in the car and the device will stop ringing. Which confirms that bluetooth sleeps somehow and only connects fully when the device is fully awake.
It really looks like bluetooth goes to sleep, so we need a solution which keeps bluetooth awake even if the device itself is in sleep mode.
Patrick

Exactly the problem I described. It's a sleep or suspend mode of the bluetooth that causes the dysfunction. I can pair nokias wih JVC without any functional problem, they work like a charm. It is really a HTC related problem, I tried a lot of registry tweaks suggested for similar problems in other HTC devices, but no luck so far.
Reply to Guitartng:
storing multiple bluetoothdevices in the JVC for subsequent use can be done by selecting "new device" and then go to "bluetooth setup".

Exact same issue with a Kenwood DNX 8120 double din unit.
If anyone finds out the solution, please post it here. I'll keep searching.

Good News Lads!
Well after blowing my head of trying different roms and radios got a solution.
The solution comes from JVC stereo and not from Htc diamond Phone!
You have to set special phones To Samsung E520 and then pair device with the htc diamond. It works like a charm, know I can make calls through my JVC stereo and NO MORE deep sleep of htc diamond.
Try with samsung, it work for me, if not try with other phones in special phones before pairing!
Cheers!

I just wanted to let you know that I also was able to fix my bluetooth issue by flashing stock firmware 2.03.405.3 WWE with Radio 1.09.25.23. I was previously using Dutty's V4 which is based on 2.03 afaik, but it look like Dutty tweaked something on the bluetooth stby behaviour.
Anyway, it works like a charm now and the whole calling and answering process is also much faster!
