HTC HD2 Bluetooth Carkit hang up bug...

Hey Guys, i'm hoping you can help me.
I have searched this forum and couldnt find anyone that has the same bug as me. I apologize in advance if there is a thread already that discusses this.
I have a Ford Mondeo Titanium X 58plate. Bluetooth syncs up and sends/receives calls great, however When I try to hang up the call it crashes. Is anyone having the same problem?
I upgraded my o2 HTC phone to the latest 1.66 rom and I still get the same problem. Any help would be appreciated.

I too have the same issue. I have a Mondeo Zetec and suffer from the same issue. After hanging up, the phone continually tries to connect and disconnect and the only way to stop it is to turn off bluetooth completely. I logged the problem with HTC and they were trying working on the problem howver I havent heard anything from them for 3 weeks. Im considering changing the bluetooth stack on the phone but arent sure how and with which stack.

I heard that changing the stack to the Microsoft default causes other issues. Let me know if you get a response from HTC regarding a fix. I dont even bother connecting the phone to the car anymore because it just crashes everytime i get a call, its so frustrating.

This is the response I got from HTC:
We can never guarantee that our products will be compatible with car kits or bluetooth headsets.
There are different ROM versions of Windows Mobile 6.5.
It might be that this product is not 100% compatible with this specific car kit.
When it comes to upgrades and updates then you will have to contact O2 for them to provide the upgrades for you.
Best regards,

Probably a generic answer to everyone.

Same issue/possible fix
I have a Titanium X sport exactly the same issue.
I was told a couple of days ago if you switch off Data connection in Wireless controls in Settings it helps and I have tested a few times and this does seem to work.
I have not had an opertunity to test thoroughly and would be interested to here if it helps you

Bluetooth issues in ICS? Post your problems and solutions!

Hey guys, I'm sure a lot of you are already on one of the ICS roms already. First of all hail all devs who have made our life better before official releases!
However I have seen posts talking about them experiencing Bluetooth problems just like I am right now and mostly mentioning the Music player stuttering and similar issues like that.
My problem is a little different. My aftermarket car deck worked perfectly with all the phones I have connected to, including my GB i727. However after I flashed the ICS my bluetooth connection kept dropping out randomly. Starting with the deck not auto connecting when I get in the car. Then after I manually connect "Phone" in the menu, it will MOST LIKELY disconnect after (on average) 2 minutes with the "Media" still checked (although the connection is not shown on either the icon in the status bar or the display of the deck). Weirdest thing is, sometimes it actually keeps on working after it connects.
I didn't think that would be a problem for me because I don't use Bluetooth earphones and I use my iPod instead of my phone to play music in my car. So I even disabled my Holo Music and my Google Play... I'm on Sean's SKY ICS 4.2D
I am just wondering if bluetooth misfunctioning is a common problem on all current ICS roms for our i727 or is it just the rom I am on right now? Because I drive a Manual car, the hand free in the car is actually very needed for me. So spread your wisdom on the bluetooth issues please!
Thank you!

my jvc car radio doesn't work at all with bluetooth sense updating to sky I c s. The stock I c s leak seemed to work pretty well however. Now the phone vibrates as if it's going to force close then disconnects the bluetooth within seconds of connecting every time.
Strangely, the radio does continue to play for a few minutes even though the radio and phone both say the device is disconnected. All kinds of weirdness going on here! I am going back to the stock leak as soon as I have time to reinstall all my apps for the millionth time.
On a side note, my monster bluetooth speakers seem to work flawlessly with all the roms i have tried. Seems I need an exterminator as I am over run with bluetooth bugs!
I am a programer. I wish I had the time to work on these and help develop these roms. The developers here are some truly talented and generous folks! After finals next week, I will try to devote some of my time to helping out this community which I gain so much from. Thanks to all of you guys! I can't wait until cm9 is in beta/release stage! That will be a dream come true!

You should try his bluetooth fixes in the op. I had about the same problem and bluetooth fix 2 resolved it. YMMV

Yep, same isdues.
Tried many things but nothing.
It worked, still does only on sky ice update 6, but the phone does not deep sleep, that's the problem so can't keep using that.
Hope official rogers will fix it.

Same here.
JVC KW-XR810 car stereo running updated firmware.
Bluetooth crashes almost immediately and the phone buzzes.
I use bluetooth for playing pandora or internet radio.
UCALC worked perfectly.
UCLD2 is where problems started for me.
I've tried both fixes listed in the SkyICS thread.

Hi
My problem with Bluetooth is pairing to the car auduo. The phone can see the device, recognizes the type and tries to pair, but after putting a code I get a connection refused error. Previously worked with stock and custom 2.x.x rooms. From is now a 4.0.4 one.
Any ideas/suggestions?
Solved by replacing Bluetooth.apk to 4.0.1 found at androidforums

Works fine in my Cayman S

Bluetooth is finally fixed for me in CM10.1. No more Bluetooth Keep Awake. No more hassle of disconnects.
VW RNS 510

Hi guys,
I have found in other forum, and it's working for me.
Break connection between car and S3, and delete devices both in car and phone.
Now try to pair them again but don't let car system to access contact and data in phone.
After I did this my connection is stable.
Guy who suggested this believes that Samsung sends too much data ( all accounts data)and car system freezes).
Hope this works for you too

[Q] Bluetooth Question

Ok, so I have an issue with my One X that I didn't have on my Galaxy Nexus. I was able to leave my bluetooth on (on the Gnex) all the time. When I got in the car, after a few seconds or so, it would connect. I never had to think about it. This was on AOSP, CM, or AOKP. No matter the build, it always worked this way.
With my One X, it never connects automatically. I feel like there's a setting I'm not seeing that I need to enable to allow it to act this way. If bluetooth is on, I have to manually tell it to connect to the stereo. Sometimes I have to shut off the bluetooth radio, turn it back one, etc etc.
This is on Sense Builds, AOKP, or CM.
Anyone have any insight? I feel like this shouldn't even be a thought. I should be able to just leave it on and never think about it.

Wrong section. Q's belong in Q&A. Let the mods know so they can move this thread.
Its not you, its the phone, or specifically the Bluetooth stack. Certain combinations of phones and Bluetooth devices (like your car stereo head unit) just don't play well together. Its the same on my car, which is a 2012 Subaru Impreza with factory head unit (which I understand is made by Kenwood). It work fine (mostly, sometimes the steering wheel controls to skip tracks won't work) once its connected. But it won't auto-connect and has to be connected manually every time I start the car. For other people's car stereos, it may work just fine.
There is nothing in Settings that will fix this. Further, I've messed with some of the system files to see if that would help (which some have pointed out has worked on other devices), but no good. I've also hoped that HTC would have fixed the problem with one of the firmware updates (as they sometimes update the BT stack when they update the firmware). But I've tried various builds, including the recent Sense JB firmware's, and the same problem persists.
I've reported the issue to HTC back when the phone was originally released in May. HTC support walked me though the usual steps of factory reset, update firmware, safe mode. But of course, none of this worked, and they logged the issue for further investigation. Aside from a change in the BT stack by HTC, I don't think there is much that can be done.
There are various apps and toggles and such that may make your life a bit easier (and others will likely suggest). And I'm using one now called Speed Enabled Bluetooth. But really, they are just half-a$$ed workarounds at best, and not a true fix. I wished the thing would just work like its supposed to.

As I already said, its dependent on the car stereo. Some will work, some won't. What make/model car, and is it the factory stereo or not?

My car is also a 2012 Subaru. its a wrx impreza, so we're in the same boat. guess its time to start looking into an aftermarket headunit.

[Q] Help!! Bluetooth Issue

Hi All,
I am having issue using bluetooth on this phone. It doesnt connect to my Jawbone ICON HD and my car bluetooth. I tried everything I know to make this work. Is this a software issue? is anyone having the same issue? Please help.
Thanks

It would help if you provide a bit more info here. Do you have the XT925 or XT926? What's your car?
I own a XT925 - Australian (Telstra) version of the Razr HD. I've been able to connect it successfully to the following devices under the stock 4.1.2 and CM10.2/11:
Macbook Pro
Skoda Bluetooth 9W3 kit
Sony SBH-50 Headset
One thing to note is that the stock 4.1.2 regressed BT functionality - it wasn't sending track information (a bug in A2DP?), this has been fixed in CM10.2/11 and I assume really the fix comes from AOSP 4.3/4.4.
Do note that sometimes your phone may not be compatible with the device you're connecting to (actually, usually it's the other way round to be honest, with the device not implementing BT profiles correctly). In-built car BT is often known to do this. The Skoda BT 9W is luckily a very forgiving module with very little trouble reported by users.
YMMV.

I have BlueConnect in my car. It used to work before with no issues but now it stopped. The bluetooth connects to my phone but no voice or anything. I also have a jawbone ICON HD, the phone wont detect it at all. I feel its a phone issue. I am on stock 4.1.2. Phone is XT926
Any thoughts?

When did it stop working? Was it after a ROM upgrade or just on its own?
Does the Bluetooth setting appear to work at all - i.e. changing visibility, etc?
Have you tried looking at the kernel logs - i.e. with logcat?

Alright so I got it to work. I had to do a full factory reset erasing all data. Now it works.
I don't remember when I stopped working. But I used to think that it was my car bluetooth until I figured that it wasn't the case.
Thanks anyway.

Bluetooth Music Choppy

Hey, got my U12 and within 12 hours looks like I might be returning it. Fantastic device Im very annoyed. Music through bluetooth to my car sounds a skipping cd. Anybody experiencing similar or any idea what to do? Changing parameters in the developer options doesn't seem to work.

No problems here with Bluetooth and Ford Sync 1.1 with latest software 5.11.

I saw in another thread that suggested going into developer options and switching Bluetooth AVRCP to v1.4 instead of 1.5. Did you try that one too?

Ya tried that, it's less severe but still happening. Iv isolated it to vw head units i think.

I was having a similar issue with my Bluetooth headphones. It kept cutting in and out while my headphones worked fine with my iPhone.
I'll be using my headphones again this evening so lets see if it happens again and if I can get more details.

I've had no problem with it in a Toyota Yaris. Also no problems with BT headphones - it's even a bit better than the U11 BT, which used to skip now & again. Had to set BT to 1.4 for full control in the car.

Maybe VW has been updating their software and you could drive by a dealership to update or do it yourself. Since Oreo came out I also had problems with BT. No media info was shown. The problem seems to be Oreo 8.0. In 8.1 Google solved some of these problems.
Since Ford brought out an update everything works fine now. Hopefully Android P has covered all these bugs.

Brand new car though. I might make a phone call about it all the same.

Found some solutions on Google that you could try out:
Settings>Apps>Application list>... >show system apps>Bluetooth>force stop, then clear data.
If this doesn't work, remove the pairing, repeat above and redo the pairing.
Or
Reset Network settings fixes the Bluetooth problem after Oreo Update. Settings > Backup & Reset > Network Settings Reset and everything works like charm.
Or
Change of Bluetooth Audio Codec (Settings -> Advanced -> Bluetooth Audio Codec) from SBC to aptX seemingly fixed it.
Hope one of them helps. Good luck!

I have also experienced this with my VW. I listen to audio books mostly and every so often a word drops out and it gets annoying.

Iv just had to switch to using the aux. Awful annoying, brand new phone and brand new car and ****ing bluetooth doesn't work properly.
I still connect to the bluetooth for calls only which has created a side problem too where if I get a call its not sending the sound through the bluetooth by default i need to manually select it.

Re: Bluetooth music choppy
Thank you phxzy , all!! Having the same annoying issues with my HTC U12 Plus Bluetooth in my car. Maps misses a lot of verbal directions and music is horrible.
Thanks for the many suggestions!! I'll try them this weekend!!

I just have some cheap BT device I found at a local discount store but I only occasionally have the choppiness. When it happens it's like the audio continues and I miss a few seconds of the audio. My main issue is more that it stops the playback altogether. It doesn't seem to disconnect just the playback stops/pauses and has to be restarted. This whole time I've been under the impression that it's the player/app but I'll try some of the advice given here and see if I can get it to improve. Thanks
