bizarre bluetooth conneciton problem...

I'm trying to connect my Sprint TP2 to my car stereo's bluetooth.
It works great for streaming audio from my phone, but when I try to make or receive a call, it's as if it's not even connected. If I call from the phone, and then click the connect button on the stereo a few times, it will connect, but then only for a second or 2 before it drops off again. The phone call never gets lost, it just doesn't work like a hands-free headset should.
What is interesting though, is if I'm playing a song from my phone, then the head set portion works exactly as it should.
I tried another phone, a Treo800, and it works as is should; you can make and receive calls as you would w/ any headset, and doesn't have to be connected via the audio profile first.
Any suggestions?

The TP2 can have some weird behavior with bluetooth car kits due to the Widcomm bluetooth stack. I applied the fix in thread linked above and haven't had any problems since with the Tilt 2 and my Acura's bluetooth system.

thanks, I'll give that a shot tonight.

didn't work for me; exactly the same behavior as before.
Additionally, the BDAddr key in HKLM\Software\WIDCOMM\BtConfig\General always resets itself when i reboot my phone (the instructions say to set the value to "no value").
I even tried changing the key type, and it reverted to binary upon reset.
I'll keep searching, but in the meantime, any other suggestions?

THIS IS DRIVING ME MAD - Bluetooth plays media files everytime I start car

My car has bluetooth built in and it works fine. It also has a USB socket, which shares the AUX button on my cars headset with the BT audio.
However, everytime I go to the car ( I leave by BT on all day as I am constantly in and out of the car) it automatically starts playing media files from the phone. When this happens, it disables the USB input , unless I pull out the USB and put it back in again.
I turn off the 'media' tick box in bluetooth settings for the pairing, hit return, yet the next time I get in the car, it turns itself back on.
Is there a way of permanently disabling the 'media' setting in the bluetooth settings for this pairing?
I have this phone also paired to another car, but that one doesn't have the media option in its settings.
Also does anyone know how to get the phone to connect to the headset during a phone call while the ringtone is ringing? This phone sends the sound over to the head unit as soon as the call is answered, meaning that I never know if it is ringing or not, or connected. It would be nice to hear the ringtone ringing over the speakers and before it is picked up.

A friend of mine has the same problem with his bluetooth carkit. But not only when he start his car. I'm curious for a solution.

It's your radio .. incorrect support and usage of bluetooth specifications

I dont think it is the radio, because I can turn off 'media'in the bluetooth settings/bluetooth devices/options, and leave 'phone'on.
The next time I get back into the car, media turns itself back on automatically and starts playing tracks from the phone through the radio.
The bluetooth pairing on the phone that exists for the other car I have does not have a media setting.
Is there an advanced bluetooth settings app that can permantly leave the 'media' button unchecked?

HTC paired with car -> No sound for the GPS!!!

Hi!,
I have a HTC Touch Pro 2 that I usually pair, via bluetooth, with my car. When this connection is made, a message shows up on the HTC’s screen informing that the connection does not assure some sound functions. Nevertheless, all the phone functions work great.
The problem is the gps. I bought a few days ago the gps software NDrive v10, and after a few tests I realised that when the HTC is paired with the car, there is no sound from the NDrive. I open NDrive and I can’t hear a single instruction!
The solution is turning off the bluetooth so I can hear the instructions from the NDrive, but this way I have no handsfree system for the phone…
Is there any way of solving this problem, having the HTC paired with the car, and at the same time, hearing the instructions from the NDrive?
Thanks!
MM

Are you pairing both Hands-free and Stereo BT profiles when you connect to the car? Maybe that program requires the Stereo profile to route sound through your system. Otherwise, only phone functions will be routed. My phone automatically pairs the Hands-free profile when I get in the car, but if I want to stream music from the phone to my car stereo I have to manually start the Stereo BT profile.

when you mentioned the car's BT profile I went and check the car menus, and I found one (that I missed previously) that gives the option of listening to the sounds from the HTC. Whether it is music or gps!
But I still have a small question. When the menu that I mentioned above is select I can only listen to sounds from the HTC. This means that when I'm listening to the gps I can't hear radio or cd player from the car...
Nevertheless, thanks for the help!

On the HTC you can pair the phone and the stereo. If you disable the stereo on the HTC, that may get you what you are after.

That's because the radio can only have one input active at a time, and when the phone is connec ted via BT in stereo mode, that's all it can handle. It doesn't matter if you're streaming music or GPS directions from the phone.

Bluetooth in car...phone and/or audio???

Hey all
I have had a lot of trouble with my Galaxy's bluetooth connecting with the system in my Infiniti M37x
I now am able to have it so everytime I get into my car, the phone's "phone" bluetooth connects automatically, I can use the hands free system to make and receive calls AND the phonebook is downloaded into the system as well. Works just GREAT! I can talk on the phone and I have my contacts there. All hands free.
But......
that is only if I pair it to the phone part of the Galaxy.
If I also pair it to the audio device, then the troubles begin.
If I were to pair the audio to my car, the music sounds great...but once I turn off the car and leave, come back, the car won't recognize the phone part. Even if I go to BLUETOOTH settings, and click the little button, it won't stay or connect to my car.
This worked great with my EVO using Gingerbread.
Is this an ICS thing?
Are there any apps that would allow me to just leave the phone as the default car connection and if I want to listen to music, just click something to switch it over to audio part?
Whenever pair to the audio and I use the audio bluetooth connection, I have to unpair and start all over to get the phone to connect.
Hopefully this makes sense. Any advice would be helpful.

This is a Samsung thing (and I hate their phones because of this)
To have this function correctly, you need to enter car dock mode. To enter car dock mode, you need a samsung car dock.
If my phone is docked, I can stream music, receive calls, etc, all work great.
If I leave it in my pocket and I stream music and receive a call, the audio comes through the phone, and not through bluetooth.
My E4GT was like this. I opened an issue with Samsung to which they replied "Working as designed"
No other phones work like this, only Samsung and their ****ty bluetooth switching.
I think you can also solve this by going AOSP or AOKP.

I have no issue with my s3 when connecting to audio or phone. and im able to answer calls, and play music no problem

How did you pair both? Do you have to switch between the two?

I am also having this same problem but only after flashing a customer ROM. With the costume ROM the phone will connect phone and I can make calls no problem but I can not get music to stream to my car stereo no matter what I do with the costume ROM when back to stock just to verify this and I have no problems streaming music on stock ROM or making calls via Bluetooth.

Sprint GS3 horrible in car
The first two days the phone worked great. Now it connects but the sound is noisy and unintelligible from either end. I don't know what changed. anyone can help me on this? can I stream music through bluetooth if it ever starts working again?

are you running the stock software not modded in any way?

[Q] Possible to route audio through A2DP and the phone's speaker simultaneously?

The subject says it all. Can I route audio through Bluetooth A2DP and the phone's speaker simultaneously? I want to keep my phone connected to my car's audio system via Bluetooth voice and A2DP. But sometimes I want to switch to XM Radio or other sources. When I do that of course, I lose audio prompts from Google Navigation.
Is this possible?

I'm looking for the same thing. I can get audio through Bluetooth and have notifications go to speaker at the same time, but I can't get other media to go to speaker at the same time.

I would also be satisfied with a widget that lets me toggle the A2DP status of the Bluetooth connection on and off. It would not be the end of the world if I needed to toggle the A2DP off when I switch to another radio source and toggle back on when I go back to Bluetooth as the source in the car.

If you ask me I'd say it's possible.Whenever my phone is connected to my stereo through A2DP, the music is played through loudspeakers only by default. However, when there's an incoming call and my ringtone is being played I can hear it through loudspeakers AND the phone speaker, which creates a pretty cool surround effect. I'd really love to make my music player interact with all the speakers like this all the time. I took my chance installing various apps like SoundAbout to help me figure it out, all to no avail. Any ideas?
