O2 XDA IIi Bluetooth with Bluetooth Car Kit Issues.

Hi Guys,
Recent got an XDA IIi after being with the older XDA II for over 16 Months.
But I have recently run into problems with my BT Car kit :
Motorola Bluetooth Car Kit HFW-8000.
Basically the problem is that it does not always connect to the Car Kit and when it does it will only from time to time connect and let me have a handfree conversation.
I have also used the Broadcom Bluetooth Cab file here in order to extend what Bluetooth Profiles that can be used but seems not to have any great bearing to stablize the issue.
So I went down the Hard Reset Road but again still intermittent issues, I then upgraded the ROM to the New one on the O2 Website the v 1.11.169 ROM.
I also had similar issues with the XDA II but it was resolved by using the Pocket Bluetooth tools, which was great and never once after installing it did I have any issues with the Car Kit.
http://www.bluetooth.jazztel.es/
One of my questions is, is there a similar programme to to above Pocket Bluetooth tools for the XDA IIi as I have tried it with the XDA IIi but does not work.
Or does anyone know how you would revert to have the XDA II radio or is there a work around for it.
Thanks Guys
Woody

Hi Woody_XDA,
I have had my XDA2i for a couple of months now and recently got a O2 blue headset for it, I had simular problems with the headset disconnecting and having to manually connect every time I switched it on. After browsing this wonderfull forum I decided to do a corperate install and get rid of the O2 active interface, since then no problems at all. I now use Pugs modified ROM version 162 with radio 1.04 and have no stability problems at all with no twice weekly reset. Hope this helps you and many thanks to Pug for his ROM.
Mace

Ditto, I also use the custom firmware with 1.04 radio and bluetooth works a charm. It still eats battery like nothing else, but it works with no problems. Also like the fact that the XDA can cope with my GPS receiver and my handsfree kit simultaneously, that's handy for in the car.

Cheers Guys for the information, took it on board and works great, did a great deal of stress testing in order to confirm it and works excellent..Thanks to PUG again and guys thanks for the info much appreciated and this is by far a great forum

Mace - you mention some bluetooth issues being resolved since you applied the custom ROM... I posted in the Alpine Applications forum here the other day a list of issues with bluetooth that I was wondering had been addressed - so far no reply - are these the symptoms that were cured for you??

Hi Bewlay Brother sorry, I missed your other post on Bluetooth issues, my original problem was that every time I switched on my BT headset , which is a O2 Blue, I had to open the BT manager and make the connection, the phone would then occasionally lose the connection and sometimes whilst still showing a connection refuse to transfer the call. This was using the official 162 ROM with the O2 active UI. I have since installed Pugs 162 ROM with radio1.04 and done a corporate install and BT seems to work perfectly, switch on the headset, it connects, never loses pairing and transfers calls.
Hope this helps you, and thanks again to Pug,
Mace.

Mace - what you describe sounds similar - my problems were essentially the loss of pairing with my Motorola headset a lot of the times when the XDAIIi switched off its display and went into stand-by mode, also if I closed the boom bike on the headset (to temporarily turn off the headset) it would fail to re-pair when I next opened the boom mike... the other issue was that I had to make sure the phone keyboard was displayed on the XDA once I had paired up otherwise the last number redial function on the headset would not work - if I pressed the dial button on headset and the phone display was not on the screen it would simply open the phone display function but fail to then dial the number - really crap. Also reception was poor to headset even over relatively short distances from the XDA. IF these areas in particular could be cured by the upgrade then I am eager to do it - I must admit I have read that this upgrade has not been without problems for some people here so it is going to be a tough call.

Just a thought, but have you done a personal or corporate install as I think the main fix with Pugs ROM was the upgrade to radio 1.04, which I don’t think affects the BT, so a corporate install with your existing ROM may make a difference.

Did a corporate install when it was new out of the box...

whats the difference between the corporate and personal install?

Corporate doesn't install ANY of the branded O2 interface - so no gubbins, nothing to slow down the phone, you just get a bog standard Windows Mobile 2003 SE installation, aside from the O2 GPRS and SMS settings. Bosh.

hi
i've been reading the posts and i have the same problem where can i get hold of pug's ROM if it's possible cos this seems to get rid of the problem

And then today, headset will not automatically connect, needing Bluetooth manager to be opened to make the connection. AARRRGH!

BT car kit problems
I have the 1.04 Radio, but it still won't sync with my 2003 BMW 325xi bluetooh or with my 2005 Acura MDX bluetooth.
Help!

Unstable Bluetooth Signal Strength - Samsung WEP200 Bluetooth Headset
Hi, I just got a Samsung WEP200 Bluetooth Headset. It would pair with my O2 XDAIIi but I cannot hear any voice in both incoming and outgoing calls. When I check the BT Manager, it shows a totally unstable BT strength that varies from very strong to very weak. The same headset worked well with other BT phones. My ROM version is 1.11.00 WWE, Radio version 1.04.00.
Any help would be greatly appreciated.

Infiniti/Nissan bluetooth problems with Tilt/8925/Kaiser

Apparently there is a known issue with the Microsoft bluetooth stack which makes it virtually useless to use this phone with Infiniti/Nissan vehicles.
I own a G37, and when I connect the Tilt, everything connects but the quality is sooooo poor that it sounds as if I have the phone in the house and the car is 100 ft away (crackling sound, and no one on the other end can hear me).
I have tried several of the roms here, including the official ones, and no luck thus far. I have tried playing around with the bitpool settings and once again no luck.
Anyone have any suggestions? Is there any way of replacing the Microsoft stack implementation from the Kaiser with the one from the Hermes? That one works perfectly with my car...

Have you tried Austinsync's clean rom? Its working fine with my M45 and I had the same problem you did with some other ROMs. Not sure if ROM change fixed it or one of the other hundred changes I make to my phone every other day. I assume you have adjusted the volume while in-call?

sell your car and buy American!

Your phone is made by a Taiwanese manufacturer. I tried searching for a American-made cellphone so that you could immediately begin your purchasing prospects, but was stunned to find that there is not one American cellphone manufacturer.
Your profile picture looks somewhat like a Dodge Ram to me. You might be interested to know that Chrysler recently built a new $315M Dodge plant in Brazil. They also worked collaboratively with Mitsubishi and Hyundai to design 3 engines that will be manufactured mostly in South Korea and Japan.
But let me get back to the topic at hand. I own a 2007 G35S Sedan and I have had very minimal trouble with my Tilt and the handsfree system. Everything works fine, including the reception meter (never worked on my 8525, even with WM6 ROMs). The only problem that I have noticed is that if I answer an incoming call using the button on the steering wheel, the car appears to start the call, though the audio is routed through the phone for the first 10 seconds and then the car resumes control. It is worth noting that I couldn't get my 8525 (WM6) to work with the car at all - even with the latest and greatest.

I will borrow my dad's Kaiser (as mine was returned earlier today), and try the Austinsnyc's superstorage rom. Hope it works, although I think it's based on the base HTC rom. As I'm sure they're using the same Bluetooth stack, problem should be the same.
Either way, I'll try and report if it works.
As far as the buying American... I thought that whole marketing scheme went out the window a few years ago when Chrysler merged with Mercedes Benz, and most of our products are made in China (as our workers are not willing to work so cheap without going on strike)... don't you just love the beauty of the world economy?

It was supposed to be a joke as it has nothing to do with the car. But since you wanted to act all high and mighty......
My Dodge ram was designed approximately 15 miles from my house. It was built 5.5 miles from my house. The company that built it employs approx 200,000+ direct employees and roughly 400,000 indirect, here in the U.S., where i live. At an average salary of $75,000 that's roughly 45,000,000,000 that the company that I buy my car from pumps back into the American economy. This does not include car dealers.
The 2007 G35S is designed in Japan. The 2007 G35S is built in Japan. The 2007 G35S employs maybe 1000 people here in the U.S. because someone has to import it and drive the boat, drive trucks, and do paper work. At an average salary(i'm sure it's way off but lets pretend) of $75,000 that's 75,000,000 that gets pumped back into the American economy. This does not include car dealers.
45,000,000,000 vs 75,000,000
yeah, you are right, it's all even. buy imported cars. it makes sense.

Thats EXACTLY the same problem with my 2007 G35 sedan and my HTC TYTN 2.
When i press the receive button, it takes 10-15 seconds to transfer over to the car audio (goes to the handset first).
THe only solution i have is to receive the call using the phone's talk button, which will go immediately to the car.
I am currently running Dutty's Touchflow Final 2 rom.
BTW. Before my G35, i had a 2006 Chrysler 300C Hemi rollin on 22's with full multimedia setup. My first domestic. I only owned imports before. After i came back to get my infinity G35 (after my major accident), i remember now why imports are so much better than domestci. The Infiniti is built like a ROCK, and the 300 was very crude in build quality.
Anyhow.

No problems in my M45...
Maybe it's the car and not the phone?
I had a G35 prior to the Bluetooth option so I cant speak about the quality there but the M45 has been pretty good. the Tilt has a low out put at times but 95% of the time it connects perfectly with zero issues. beats using a headset imo

could be the car, but more than likely it's not... here's why:
I have successfully paired and used 2 tytn, 2 8125 (Wizard), and 1 ol' school SMT5600. All worked fine without any crackling, or the other person on the other end not hearing me...
On the other hand, I have tried 2 Kaisers and both exhibit the exact same things...
(btw, in the info screen about the bluetooth connection the connection shows up as "poor" for the kaisers, excellent for the rest...)
It's hard to believe that I'm the only a-hole that has the Kaiser/Tilt and G37 combo out there... anyone else having the same problem or am I alone on this one?

Did you not read my post? I have a Tytn 2 and a 2007 G35 sedan with the exact same problems as you.. Just use the Talk button on your phone to receive calls..
Arent you on G35drivers.com?

Tilt + my Mercedes work great.

Same problem w/ Tilt & G35x
Not that I'm glad anyone is having this problem but glad to see it isn't just me. I started with an unlocked imported TyTN (Hermes) phone that worked perfectly in my '07 G35x purchased in May. I never had one problem pairing in the car, receiving or making calls, using voice commands via the car or audio quality.
As soon as I purchased my Tilt I immediately had problems in the G35x but not with any other bluetooth device (I also have a Garmin c550 and pair and make / receive calls with it without any problems).
I can pair the Tilt with the car - no problem. I can use voice commands to make a call - no problem. As soon as the phone starts to ring through the car speakers I can tell there will be a problem because the ring is very 'tinny'. I can hear the person answer and speak but they cannot hear me at all. I then put Dutty's ROM on the phone thinking maybe it was a stack issue that might have been resolved in a new ROM (assuming their had been updates to the BT stack). That did not make any difference.
I will by tomorrow test my corporate Blackberry in the car again. I had used it in the car via bluetooth while I had the Hermes - no problem. I will retest now that the Tilt isn't working.
Have any of you contacted Infiniti and / or AT&T? I could only assume until they have a quantity of calls will they say anything other than "not our problem" or, "never heard of that before".
If there are others with this problem it would be good for them to acknowledge their experience here along with any comparative good/bad feedback with other phones in the same and different car / devices.
Update: I've just tested my Blackberry 8700 that worked prior to pairing the Tilt with the G35. I can confirm that the Blackberry still works flawlessly. As the Tilt also works flawlessly with my Garmin device I think the cause is unclear but would appear to be with the Tilt as it is the only thing that has changed in the tests I've identified above.
Regards,
David

well, one of the ways I use the phone also is calling out... when I dial the number and call from the phone, the car bluetooth connects and the crackling starts... (i call my voicemail to test).
besides being an Infiniti/Nissan issue, it appears it is far more widespread... there's already a 20 page thread on BT and Kaiser! from that thread it appears HTC is aware of the issue and is working on an upgraded stack/rom... everyone cross your fingers and hope that one works!

Could you provide the link to that thread?

Multiple solutions...
I'm using Dutty's TouchFlo Final Rom and I'm not having any problems with my 2006 M. So maybe you can try that ROM.
But on the M, I did have horrible problems with my E-Ten M500+ (continous feedback...C R A Z Y), and limited functionalities with my 3125. Both of those problems were solved instantly with this software: http://www.jetwaremobile.com/ They offer 30 day trial of their software, so try it.

I do not have this issue with my g35... I do not get any crackling.. Its only when i try to receive calls, it delays like 10-15 seconds!!!
Making calls is NON-issue...

it really is crazy... I've tried that particular rom and it has the exact same problem. I have also tried the Jetware bluetooth stack, and once again, it does the same thing. I've tried about 5-6 different roms, from super clean roms, bigstorage, to the latest build numbers that I could find, and all do the exact same thing. I've played around with the bitpool settings, audiogateway settings, and nothing...
It may be that the combination of the G37 + Tilt just has something in there that makes it go crazy. Could be the car, but as I've said earlier, all other phones work, including the Hermes, without any problems whatsoever.
Anyone out there with a G37 willing to give the Tilt a try? I'm about to go to the dealer and pair it with other cars to see if it works!

If you have the G37 (coupe I guess?) then you have the 2008, right? I know they switched to the new hard drive based system. So maybe they don't have all the bugs worked out. Top it all off, MS's bluetooth stack is kinda shaky, so it might be amplifying the problem.
I don't see any service bulletins relating to this issue on your car either: http://x.infinitihelp.com/forum/local_links.php?catid=86 I doubt that Voice Recog system update will fix your bluetooth issues...but then it might. Worth a try.

Can the Tilt/Kaiser Bluetooth Stack be replaced?

I've been having some issues with my Tilt and my car's hands free setup (see: http://forums.wireless.att.com/cng/board/message?board.id=cingular&message.id=105410). The problems seems to lie with the Microsoft bluetooth stack on WM 6.1. HTC is no help with this issue so I want to take matters into my own hands. Is there a way to replace the default Microsoft bluetooth stack with another, more reliable compatible stack from a reliable company (not Microsoft or HTC)? I don't want to get rid of my Tilt, but I need it to work right in my car. I'm thinking of staying away from purchasing WM 6.1 smartphones because of this.

frustrated...
Wow, no one has answered my post here, at ATT, at Kenwood, or on tiltsite. HTC answered only to tell me that compatibility doesn't necessarily mean that it would work (bs). This is very frustrating. I've read post all over xda developers and the rest of the internet about tilt bluetooth problems yet no one has an answer. I've completely giving up on trying to get bluetooth to work right with any of my devices (car, computer, etc). I can't imagine buying another HTC product. Good luck to everyone else out there struggling to get bluetooth to work on their tilt while the motorola, blackberry, lg, samsung, and other phone users watch with amazement and pity. Keep fighting the good fight. Hopefully one of you will win. I've completely lost!

That's a pretty strange story you've got there, because I have zero problems with my Tilt and bluetooth pairing to all manners of devices... on a regular basis, I connect my Tilt to my car's Pioneer stereo deck, to my laptop and desktop, and to my wireless headphones and I've had little to no difficulty. Actually, the easiest pairings so far have been between my Tilt and Pioneer Stereo Deck... At least for basic features - in order for the phone book entries to show on the deck's LCD display it required an upgrade from WinMo 6.0 to 6.1 and then in the deck itself I have to manually download the contact book. But that's the only troublesome thing I have to do, which is mostly an advanced feature any way that I could live (but prefer not to) without.
Sucks that you're having problems, all I can suggest is make sure you're doing everything properly... I've had no problems I couldn't overcome with my Tilt and bluetooth capable devices, especially since Windows Mobile 6.1 came out.

Hi,
I'm having the same problems, also when disconnecting from the BT carstereo after a phonecall, the device freezes up.
Anybody found a solution for this problem yet ?
Ny the way, my car stereo is a JVC KD-BT1
GRTZ,
Niels

From what I can tell, they've ported the Widcomm BT stack to the Hermes and TyTN, so I imagine it's not far off from the Kaiser/TyTN-II, if it doesn't already work (my BT is working fine, so I'm not too likely to mes with my phone to find out-- but I hope this helps!)

I got it working with a Pioneer deck in Best Buy. I was actually debating buying one, but I paid $500 for my Kenwood setup. All of my other phones work with it, to include other WM phone (not from HTC). I contacted Kenwood, but I have not recieved a reply.
@Weasel5i2
I tried the Widcomm stack when I used the stock ATT rom. It completely disabled bluetooth on the Tilt. I will try it with the PDA Corner rom I'm currently using (the best!) after the holiday weekend.
Thanks again for the replies!

I am experiencing Bluetooth connection issues between the Tytn2 and a kenwood DNX8220BT As far as I've heard from kenwood the Tytn2 is only supported with the older version of Windows Mobile (6.0)
I've also tried the Kenwood with my wife's Touch Diamond (Also HTC but other CPU, don't know about the BT radio though) but that one is also experiencing trouble. I didn't get any indication when they would have a new firmware version ready.
You did indicate that you also tried another WM phone, which version of WM does that one operate on?

@Mautje
The other WM phone was a Samsung Blackjack II running WM 5. I downgraded my Tilt to the default WM 6 Rom from ATT, but I had the same problems. I'm running the PDA Corner WM 6.1 Rom now. Does matter which ROM I use, I get the same results on the Tilt.

widcomm stack a no-go
I tried the Widcomm stack. It did not work at all. Kept getting error that "there was not enough memory to run, please reset device" or something to that nature. Could not uninstall so I had to re-flash my ROM. Back to square one.

To bad. I was also looking into the other roms on this forum but it wil probably not work..
Kenwood is reporting that it should work with the rom version mentioned in the compatibility sheet.
In the sheet for version 1.43 firmware there is no mention at all of a rom version just the Tytn2.. I guess that's the WM 6.0 version

BT connection to BMW 1 hands free aborts

hi,
I am driving a BMW series 1. I have an integrated hands free system in the car. I can connect the Touch Diamond with it. Even all the contacts can be shown and dialed with the multi functional buttons on the steering wheel and the radio. Here comes the issue:
During a call the BT connection aborts. Sometimes after 5 seconds, sometimes after 5 minutes. When TomTom Navigator is running it hardly ever worked. So my guess is, it is a performance issue and if TomTom is not running then it only aborts because the battery gets below 60% and perhaps some kind of powersave mode would be activated? I am using a cooked Rom based on the latest original HTC Rom. With the original ROM it was even worse. I hope a cooked ROM would solve the issue. Unfortunately not.
The technical support from HTC told me to ask my car manufacturer. They told me of course the opposite. After I told the HTC guy that it works fine sometimes and I guess it is because of the battery, he just told me to keep it loaded all the time. Quiet funny, but if the performance is the reason then it will never work with TomTom used at the same time.
So, does anyone has any good idea what I could do? Are there any patches available?
I would be really happy for any answer. thanks

I had an issue with connecting my diamond to my X5. I fixed it by changing the bluetooth handsfree gateway dll from HTC custom dll to the Microsoft voicecommand dll. Not sure if it will address your issue, but it is worth a shot.
I posted it on ppcgeeks.com. (Sorry i dont have the link handy at the moment)

thanks a lot. i will try and post the results.

Xperia Bluetooth problems :P

So I have an xperia, and I have a new JVC Bluetooth deck, I was so impressed how flawlessly it worked with my old phone the Kaiser/tilt, but to my surprise I have not been able to get it to properly pair up with my newer xperia. They will read each other and try to connect but I always end up getting an error. Sometimes it still shows up as connected but nothing works. I used my kaiser/tilt for both calls and streaming music through my new JVC bluetooth deck and I loved it, so its pretty dissapointing when I upgrade to what is/was one of the hottest & expensive windows mobile phones and it apparently has bluetooth issues.
I tried a few fixes already like changing the registry to read as a normal phone and I added in a missing bt profile, unfortunately nothings changed. I am curious tho because i had a magician and they had whole bt stacks that I messed around with, and I'm also wondering if a flash or two of a new rom may make a difference. Ocerall I'm really happy with the X1 (unlike my tilt/kaiser which had lots of problems) so much so that I don't really feel the need to flash a new rom, but if it might have a chance of fixing my bt I'm all for it.
Let me know if anyone has any suggestions, tia.
