Hello!
I have one question regarding BT when connected to my carkit. Here is the situation.
I owe a Citroen C5 III with factory supplied carkit. I had an HTC touch HD, which was working excellent. Then I have swiched to HTC TP2 and here is where the problems started. The TP2 connects to my carkit with no problems, but when I make a call the phone starts to work really slowly. It take about 30seconds to hang up the call I just had. If I want to make another call the phone still works very slowly, making the call takes about 1 minute. Phone strats to work fast again as soon as I disconnect the phone from carkit.
I have tried to change the roms (a lot of them with and without manila), I have taken my car to dealershop to updtae the BT on my carkit.
I there any solution for this problem?
Is there any way I can update or. downgrade the bluetooth drivers on TP2 so there would be the old interface just like the HD had?
Thanks a lot for all your help!

Check out this thread: http://forum.xda-developers.com/showthread.php?t=591322
On page two there is a list of the registry edits to apply to fix issues between the Widcomm bluetooth stack and bluetooth car kits.
Dwboston, thanks for your reply. It helped a lot. I did the changes as described on second page on the link you have provided. I did not find the last entry I was supposed to change.
I went on a short test drive and looks like the carkit is now working perfectly. Tomorow I will go on a trip for two days. after that I will tell if the tweak worked.
Again, thanks a lot for the help. You have no idea how you made my day.

I didn't have the last entry either on my Tilt 2. So far the phone is working fine with the bluetooth system in my Acura. Hopefully it keeps working.
I did some testing. Although it works fast, the address book is now not synching with the carkit. Any idea about that?

Sorry - not sure about that one. My bluetooth system doesn't support phonebook synching.
I figured it out. When I have changed the Change SupportedFeatures to 45, I have changed decimal value. Now I have set hex value to 45 it has started to work. dwboston thanks a lot for all you help. If you ever come to Slovenia, I will buy you a cup coffe.)
My girlfriend and I both have HTC Desires (one unbranded and one Vodafone). We recently got a 2005 BMW 5 series with the I-Drive Pro Nav system in it.
When I try to use BT to connect to the car, I can manage to pair them, but when the phone goes to connect to the car, it only connects for a few seconds and then disconnects. It then connects again and the whole thing repeats. The disconnect is frequent enough (every few seconds) to render the whole thing unusable. It also means that it isn't connected long enough to transfer the phone book.
Both our Desire's have this problem (they have different firmwares). I thought that maybe it was the car, but I put my SIM into my old Xperia X1 and it worked flawlessly with the car.
Is there a setting on the phone that needs adjusting or is it a firmware problem? I hear other people with the same car having no problems with the Desire. I've also used my Desire in a Toyota Avensis and a Vauxhall Insignia with no problems.
Any advice would be gratefully received.

Hi,
I know there are some issues when it comes to Bluetooth and Android, and especially car kits.
Ref (sound quality): http://code.google.com/p/android/issues/detail?id=9888
Ref (disconnections): http://code.google.com/p/android/issues/detail?id=5452
This is supposed to be a fix (I did not get it to work properly): http://forum.xda-developers.com/showthread.php?t=731626
I know that Cyanogenmod has made some changes to their kernel in 6.1 that adresses audio quality (bitpool increased), and I also think that the disconnection is adressed. I'm actually testing it for the moment (6.1RC2).
Thanks very much for your reply - very useful. The link to disconnections that you gave shows someone else with the same car as us (slightly different model) with the same issue.
It's very strange as there are people reporting no problems at all with that car/phone combination.
Unfortunately, I can't try the suggested fix as I don't want to start mucking around with my ROM.
I have a problem with my Volvo and the Desire. No disconnections, but I can't get into the phonebook, using PBAP.
Flashing a MIUI Rom works charming for the bluetooth connectivity, however I'm missing my SenseUI.
Just hoping, praying, some def will include the AOSP bluetoothstack in a SenseUI-Rom
BMW Software update
Hi
I´d try contacting your local BMW workshop, to let them do a reading on your car to establish which software version your car have.
If it´s a rather old software version your car have, I´d suggest that you have it updated.
The software update might be the answer to your problems, and can also explain why other users with the same car don´t have this issue (they might have a newer software version than you).
Remember, this phone is way newer than the car, and also the software in it.
I´d give it a try
PS: Be advised. Updating from very old software to new software might cause "in car-hardware" compatibility issues, and demand new hardware in the car (computer modules ect.), so make sure you talk over which consequences the update could have for your specific car before the update is carried out
Cheers
-Buggi- (BMW workshop foreman in Denmark)
Thanks for that advice. I'll talk to the dealership and see about software upgrades. Fingers crossed!
I have a 2008 530i and my Desire (and my other halfs) work fine, so hopefully there is some newer firmware for yours. They facelifted the cars and slightly changed the iDrive in 2007 though so fingers crossed there is an update that fixes the pre-LCI models with a Desire.
Just for reference, this is sorted out now.
My I-Drive actually broke and I had a whole new unit put in (under warranty thankfully!). Since they were doing that, I begged them for the latest software, not just for the Bluetooth module, but for the system as a whole.
Since the software upgrade, the phone stays connected and everything works great.
The only fly in the ointment is that it seems that for some reason, not all numbers of contacts (or all contacts) make it into the car's phone book (most of them do).
Anyway, for anyone else having this issue, get BMW to upgrade your BT software (or the whole system if you're brave).
I have similar problem when i try to pair the phone with volkswagen tiguan 2010, it says "your phone in not supported"
Okay so, I have read a couple of threads that somewhat touch base on my issue, however are not specific to my phone so I thought I would drill down to the subject matter in a new thread.
I just got a new SGS2E4GT yesterday as a replacement for my EVO4G. So far I love it, however when I paired it into my vehicle's (2011 Hyundai Elantra) bluetooth system, It connected to phone & media with no problem, but did not download the contact book.
Is there a fix, setting, or something I am missing within the SGS24E4GT?
I guess the thing that is a bit perturbing to me is that my good ol EVO had no issues whatsoever with pairing up.....
One option you might try is to remove pairing from both devices.
Then try to re-pair them.
I have a parrot CK-3100 BT setup in my truck and the first pairing didnt go well.
Removed it and re-did it. It asked me to allow access to my phone book. It was an option i had to check and after that its worked every time.
Also, check with the vehicle manufacturer and see if any software updates are available for your BT device in your vehicle.
It might not be an issue with the Epic Tocuch but with the other device playing nicely with the Touch.
Thanks very much. Will do as soon as I get out of work tonight
There are various threads on this forum concerning bluetooth connectivity to the GN 10.1 2014. Most notably, keyboards that keep disconnecting.
I ran into this problem with my Logitech K810 keyboard, which works perfectly on my PC, as well as my Ipad 2 and my Galaxy S4. Three different units, three different operating systems, and with flawless performance.
Then I buy the pinnacle of Tablet technology; a spanking new Galaxy Note, and realize that the keyboard disconnects every three to five seconds.
This is something like buying a shining new bike, coming home full of expectations, and unpack it. Only to discover that the wheels are stuck. They won't turn. It would have been hilarious, if the tablet wasn't so bloody expensive.
I tried various "keep bluetooth alive" and "change to another screen keyboard" apps, to no avail. Then I read a thread from someone who could make the keyboard work if they played music to another unit via bluetooth: I tried this, and voila! As long as I keep my phone paired and connected to the note, the keyboard works perfectly.
This could give a hint as to the nature of the problem; could it be that the keyboard, unlike the Galaxy S4, doen't actively work to keep the bluetooth radio active when you are not typing, and that what ppl assume to be Samsung's new implementation of the bluetooth standard in the GN 10.1 2014 doesn't take such devices into account?
If that is the case, the problem should not be related to hardware issues with the bluetooth antenna, like someone suggested, but is more likely software-related, and hence, a bugfix shouldn't be impossible.
Could this be achieved with an app written by some skilled coder, or do we have to wait for a bugfix from Samsung? Any ideas guys?

It's a h/w problem. There are plenty of N10.1-14 owners that aren't having any BT issues including with the K810 which comes up frequently. I have a BT mouse and keyboard connected for hours at a time without any disconnects. I leave BT on continually on my N10.1-14 and as soon as the mouse or keyboard are turned on they connect immediately. There's a lot of discussion in the BT thread in the general section discussing possible causes on devices having problems. Exchange it or send it in for warranty repair.

Thanks for advice, but for an exchange of the device to be meaningful, we will need some confirmation that Samsung has identified the problem and corrected it?

If you bought from Samsung, I'm not surprised they told you they would not exchange it. Samsung told me they don't warrant that their product will work with a third-party product. They also said there were no Samsung keyboards at this time that were compatible with this tablet. Fortunately I got mine from a retailer that was willing to exchange. Unfortunately the second unit I got about two weeks ago also has the problem.
Your best bet might be to send it to Samsung rather than play "exchange roulette." Here's what to tell Samsung customer support...
"Hi Mary, I spoke to someone earlier about a BT problem I was having. The BT peripherals I connect work fine initially but can't maintain a connection; meaning they drop the connection and either I have to reconnect them manually or sometimes they'll reconnect themselves only to drop out again. The person I first spoke to was pretty sure it was the devices I was connecting and not my tablet.
Here's what I did. I completely reformatted my tablet to the way it came out of the box. I didn't even allow any of my apps to be loaded on it after I reset it. So it was a clean untouched stock as it left the factory Samsung configuration. The same problems of random disconnection occurred. I went to Best Buy and they were really nice. They allowed me to connect all the BT peripherals I was having problems with to their three floor models. They all worked fine and kept the BT connection active. So clearly, there's something wrong with my individual tablet.
I have a couple of friends with this tablet and while the majority of their devices work fine some are having the same issue I am. There's obviously something wrong with a subset of these tablets for individual examples to perform differently with the exact same BT peripherals."
If you still meet resistance...
"I'm sorry you won't help me get my problem solved. Do you think a supervisor might be able to help me or should I just contact the BBB and my local attorney general's office as you're refusing warranty work I'm entitled to in spite of the steps I've taken to isolate a problem and demonstrate to you that there's an issue with my specific tablet. Also, can you please give me your name again? I didn't write it down when you came on the call."
Thanks BarryH.

Good Evening.
There are new on this issue?
I have k810 keyboard too, and in the beginning the keyboard worked normally, but lately, I have more and more disconnections.
Before, it was enough for me to restart the tablet, and the keyboard walked fine.
But now, I have constantly disconnections, every 5 seconds.
It becomes unusable
I tried to flash roms of over counties, I tried CleanRom, but the problem stays.
I'm worried, because my Knox is on 1, and I just read that Samsung voids the warranty, regardless of the problem...
Do you found other solutions since?
(.. and sorry for my bad english..)

This is something like buying a shining new bike, coming home full of expectations, and unpack it. Only to discover that the wheels are stuck. They won't turn. When you call the manufacturer support; which I did in relation to the Note, they politely inform you that they have never guaranteed theat the wheels on the bike would turn. They have only said that the bike HAS wheels,..... not that they can actually be used for anything..... so they refuse to take responsibility, and refuse to give you a refund.
This is, in point of fact, the answer I got from Samsung: they market the unit as having bluetooth functionality, but won't take responsibility if it doesn't work, and the user is stuck with a pieece of equipment that can't be used for the intended purpose. It would have been hilarious, if the tablet wasn't so bloody expensive.
So much for Samsungs costumer support. Now to my own investigation into this problem:

I have had the same problem with a bluetooth keyboard and mouse not working correctly, I found if I turn off the wifi radio on p600 I have up to 3 co current bluetooth connection going at he same time. when the wifi is on and active the bluetooth is dropping off think it has to do with wifi 4.0 radio in the tablet or the placements of the attennas in the tablet.
What I do is connect a bluetooth device to play music continuesly, so that the connection doesn't drop. Then the BT keyboard and BT mouse will stay connected. Keyboard and mouse disconnect when you stop typing. The music BT device keep the signal alive, and it never drops. You can try this if you want and check if it works for you.

I have not experienced this issue and I use a Bluetooth keyboard and mouse abort 20 hours per week.
Via my Note 3
Bit of an old question now, but I'm getting this on my K810 too Did anyone sort it out?
Theres an app called bluetooth keep alive, it works well
Cheers moabizza, I just tried it and sadly it didn't work Oh well, looks like it's going to have to go back for repair.
Don't send your device in for repair- there's nothing wrong with it. I use a BT keyboard and a BT mouse all the time with this device and they work quite well- the issue is pretty obviously the Logitech K810, not the Note 10.1 .
Hello ...
I currently have an HTC One M8 running the TeamVenom rom 4.1.0. When I pair my phone to my car's Bluetooth handsfree, it works as expected. But when I disconnect or turn off the engine, reconnect or restart the car, the pairing is lost. My phone will keep asking for the pair security code. When I enter it, I get an error saying that it's been declined (or something similar). The only way to fix it is to delete the pairing on the phone and the car, re-setup the pair and it works again. Before I Updated to 4.1.0, my phone would connect to the car automatically without issue. Also, when setting a new pair, I get a slew of message on my phone (50+), saying that a new Bluetooth device has been added. Most of the time, it's the MAC address of the car. The rest are MAC address I don't recognize.
Has anyone else had this problem or know how to fix it? Or know how to fix it? Re-adding it every time I get into the car is a huge pain in the arse.
Any help will be greatly appreciated.
See if you car stereo has a way to "re-initialize" or restore to defaults; then pair the phone again from scratch. I had a similar (although not identical) sounding problem with my 2012 Subaru Impreza (I understand their factory head units are made by Kenwood) where I would have to manually reconnect (it was paired, but would not automatically connect on it own) every time I got into the car and started it. Re-initializing the system, then pairing it fresh again solves this issue for me. I need to do this every time I flash a new ROM; on this phone and on my old One X EVITA.
Might not help your situation, but its worth a try.
I believe I remember seeing that option in the settings. I'll give that a try and report back. Thanks. =)
Hi redpoint73.
I was able to get my phone to pair permanently with my car. I wasn't able to locate the factory reset for the radio. I phone my local Honda dealer and they suggested to pair the phone/car via the phone instead of going through the car, which worked. I appreciate your help. Thanks.

I am having the exact same issue. i am on ARHD 34.6 ROM and everytime i am required to repair my bluetooth, it just doesn't reconnect automaticlaly after my engine dies.
I also have this issue with ViperROM.
This issue doesn't show up when i am on GPE ROM so there is nothing wrong with my hardware.
This has been bugging me for a long time as i need my BT audio while i am driving. I never had a problem before the Lolipop with Sense update.
I am driving a Honda City 2014 (Malaysia). Does this only happen to Honda Cars? i have asked people inside ARHD thread but not many reported this same issue.

I wouldn't assume that. There are lots of combinations of car stereos and phones that work a little differently from each other, with different hardware and software. The Bluetooth "standard" is not as uniform as you would hope. Therefore you end up with some combinations that simply don't play together well.
It partially may depend on who manufactures the head unit. Which is typically not the car company. For instance most Subaru stereo head units are made by Kenwood from what I've read. And the manufacturer may or may not be the same as the previous post depending on model, year, etc. And if you have a navigation head unit or some other "option" upgrade stereo, it might be a different make from the "base" stereo as well.
Did you try the fix mentioned in the post just above yours? Or the fix I suggested?
