Streaming audio to car stereo via bluetooth?

Hi, I'm a first time poster and I'm on the verge of pulling my hair out.
I have an SPV M600 and have just bought a Pioneer DEH P75BT car stereo because of its bluetooth capabilities.
It has two bluetooth modes: Telephone and BT Audio. After a lot of playing around I have managed to get both modes working together....ish!!!
I've installed the A2DP hack from this site enabling the streaming audio which actually sounds fantastic through the car speakers.
The problem is that to get the BT Audio to work I have to delete and repair the phone with the stereo every time I get in the car. This involves the following actions:
Open Comm Manager
Tap settings
Tap bluetooth settings
Tap devices
Tap and hold the Pioneer BT unit
Tap delete
Tap yes to confirm deletion
Tap new partnership
Wait for scanning to complete
Tap the Pioneer BT unit
Tap next
Enter passkey (four taps)
Tap next
Tap finish
As you can imagine, this process is a real pain in the backside every time I get in the car so my question is this.
Can the above actions be automated in just one command? If so how? (bearing in mind I do not really know how to write scripts)
If someone could even point me in the direction of learning to write a script for this I would be grateful. I have downloaded and installed MortScript but I don't really know what I'm doing with it.
Why when you tap and hold the device doesn't the "set as wireless stereo" command work the same as when the stereo and phone are newly paired? Surely it's the same command.
Any help would be gratefully received.

Can't help you except to say that I experienced the same with a pioneer BT radio too. My soolution was to return it to the store and buy myself a parrot BT car kit which works just fine...

Luckily I don't give up this easily. I have played around with and taught myself the basics of mortscript and have managed to write myself a script that does all of the above in one command. It's not quite perfect yet but it does mean that I can get in my car and start driving whilst the phone is busy pairing itself with the stereo.
The problems I am having so far are as follows:
I have to soft reset the phone each time before pairing with the stereo, otherwise the audio only seems to be transmitted to the front left speaker in my car, which is a bit strange.
I am forcing mortscript to try to pair with the first device in the list of detected devices, which is fine if there's no-one alse with a bluetooth device in the vicinity but not if there is and it detects theirs before mine.
Does anyone know if I could get mortscript to select a detected device by it's name "Pioneer BT unit" rather than selecting the device by simulating a tap on the screen? Also, if the device called "Pioneer BT unit" is not found the first time, scan for bluetooth devices again.
Any help would be much appreciated.

Hello I had the same problem: erase, new, etc.
but i have discovered one thing: you must only change de name in the bt description of your hands free

I was just about to point this fella in your direction ...
You'd have to do an indefinite loop while checking a registry value to see if your stereo was found. There is a key, i'm sure, for a list of found devices but I don't know where that is. As for detecting your car stereo as the one to pair with; depends on what keys are saved, sounds like it may just be possible.
I'll have a look into this as I'd like to get this stereo also if it can connect & stream automatically

If returning it is still an option, I'd get the Sony Bluetooth Audio headunit. Works great for listening to audio from your phone. It pairs it automatically. I also use Jawbone headset for talking on the phone. It kicks off the stereo and goes to the headset when a call comes in.
The built in mic is in the headunit and in my loud car, its subpar in quality. Whicj is why I use the excellent Jawbone.

I personally own a Peekton 950 car stereo and it works great with my wm5 (a2dp enabled) and my new WM6. the only thing that it does not do is autodiscover and connect the A2DP while it does it for the headset profile.
one other thing I would enjoy is to have the idtag displayed while getting the A2dp but I guess this is not part of the spec.

As I wrote in this topic, I guess the A2DP profile has two way of linking.
1°) The "headset" way : a bluetooth A2DP headset initiates communication to the music player/WM device.
2°) The "passive" way : The speaker just waits for a known bluetooth audio player to connect/link to it.
What surprises me is the fact you need to unpair-repair your device everytime : have you tried what I explain in the previous topic : just go to bluetooth devices , long tap on your spearker's name and choose "use as bluetooth speaker" (may not be exact name of the option since I've a French phone ).
On my phone, this simple (but annoying enough) action connects my phone to my bluetooth speaker (not an in-car one).
Hope this helps
PS : If you find any way to script/automatize the connection or any app more convenient than opeining the bluetooth setting, I'd be very pleased to be informed

This probably wont help the OP's problem, but for the rest, this freeware is brilliant, and can be automated using command line switches to work via mapped keys.

Many thanks for this piece of software Susur. I tried it, but I didn't manage to use it to initiate connection to my bluetooth a2dp speaker.
It's a very usefull software when your device is connected to an A2DP speaker/headphone.

There is a DIY option bluetooth headset acting as audio receiver.

A2DP - Automatic Stereo Audio

I have searched around XDA and haven't found a solution to this yet.
I have a wireless transmitter to play music in my car. When I turn bluetooth on it automatically turns on 'Hands-Free' but doesn't turn on 'Stereo Audio'.
Previously on my Kaiser (with a different car kit) turning on the transmitter set it up automatically.
I have tried AutoA2DP (from http://forum.xda-developers.com/showthread.php?t=530932) but I'm not sure it worked - it certainly hasn't achieved the effect I want (although it does seem to open Media Player when I connect now).
Anyone found a solution on the TP2?
Cheers,

I did have take a quick look at my TP2, because I had no problem with the connection. My car radio (Sony Xplod) gives 2 icons... 1 from the hands-free and the other of my Audio. I've looked in my settings for you, and found one option what must be checked. It's something like: Make a seperate connection for handfree and audio! (I'm guissing to that sentence becuase I have a dutch ROM!)
Hope it helped you!

EDIT:
Just did take a closer look into my car, and now it also didn't take the extra connection with my sterio audio. This is the solution:
Go to Com Manager
Press Setting
Press Bluetooth
Take the second tab
And tap than Sterio Audio
Now He's saying he's trying to make a connection e voila! Now it's playing music true your car audio!
(This is the way with TF3D2!'

Yes - I've been doing this every time I get in my car - I just wish there was a way of doing it automatically (and then preventing the message 'You can't control audio via this headset' or similar).

Hi,
Same problem in my car. Same car radio working with two (Sony Ericsson) phones I used before. They always connected immediately (both 'Hands-Free' + 'Stereo Audio). Strange that the TP2 is not comfortable with this simple task. Indeed, I think the option "Connect separately to Bluetooth hands-free and stereo audio services" should be unchecked but despite this option, the TP2 is still waiting for the appropriate tap. Going to BT settings and tapping 'Stereo Audio' each and every time is frustrating and uncomfortable.

Added subscription to this topic.
I'm a bit frustrated too with the AD2P auto connect problem.
I have a Sony MEX-BT3700U Car radio.
When I sit in my car, the handsfree function connects automatically with no hassle.
But not the Stereo Audio (A2DP) function. I connect it via the Bluetooth settings. After that it works great.
The problem is I'm always focused to activate AD2P manually first before I drive and forget that I have yet to start the car. So I have to start over. Going to settings > Bluetooth Settings etc. etc. ANNOYING!
So. I tried A2DP Toggle in combination with A2DP Auto Connect. Doesn't work.
Went searching for hours... But nothing. Think it has todo with the different BT Stack compared to other HTC's.
Still hoping for a solution.

@Ramsfan_Jim: which wireless transmitter are you using? I'm thinking of buying one to use w/my TP2. My factory head unit (VW Monsoon) doesn't support bluetooth.

I originally used a Venturi Mini - which had the advantage that it automatically set up handsfree & audio transmission as soon as I turned it on, but unfortunately it broke (repeatedly) with regular use.
I now use this one http://cgi.ebay.co.uk/Car-MP3-FM-Transmitter-Bluetooth-Handfree-w-2-Remotes_W0QQitemZ250445424484QQcmdZViewItemQQptZLH_DefaultDomain_3?hash=item3a4fb5e764&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A6%7C72%3A1683%7C293%3A7%7C294%3A25 which is much sturdier - and seems to have a stronger signal. However, I have to change the bluetooth settings on the TP2 to enable Stereo Audio each time I connect.
Warning - this is a much bigger device, so dependent on where your cigarette lighter is in the car, it may get in the way. I had to buy an extension lead to move it so I could use the gearstick!

Newsflash.
Found out how to auto connect to my bluetooth car radio with my TP2.
I have a radio channel bar (or whatever it's called in english) from one to six. There's a "pause/play" description small above the number five. I accidentally pressed it and it suddenly connected my phone through AD2P.
So just press play and it gets connected. So no software needed for me.

I don't use a BT car radio but I do have a stereo BT and a regular BT headset. The stereo BT has both Handsfree and A2DP profiles. But since I use the A2DP only, in my Kaiser under BT Services I unchecked the Handsfree profile and now my stereo BT autoconnects every time.

ChriX84: thanx, very interesting information, will try it tonight in my car !
Another interesting info (might be useful in terms of a .cab file preparation...): a "BT Mono" (i.e. not Stereo Audio (A2DP)) with a very low volume signal is obtained (in my car radio at least) when pressing the "Play" button on the media player (Core or WMP) while still having Stereo Audio option switched off under the BT settings.

When A2DP isnt active but Headset is connected then you will always listen mono music in your headset...Its normal

This worked for me too. Was bugging me to the extent where I wasn't bothering streaming audio any more!
Nice tip

I always burned new mp3 cd's or connected my mp3player/phone through a aux-cable.
Bluetooth Stereo Music is a huge step forward for me. The ease of using one device for everything. Calling, playing music without any cables. Thank god for that invention.

What exactly is a radio channel bar? Do you mean like a media widget or radio widget?
Personally this a2dp bug is a deal breaker for me. I primarily use my device for audio streaming.

The bar with all the channel buttons. 1,2,3,4,5 etc.
Above or under those buttons there are little symbols with play/pause etc.

Bluetooth: Paired but not Connected

I have my Droid Incredible and my Mac computer paired but I have no idea how to connect them. Anyone know how to?

i need to know also...

is the mac in your list? you should just be able to click on it and it'll connect.

Im having this issue with a motorola car system
it will pair, but will not connect...
May be related to your issue ?
I hope someone can offer some suggestions

My computer is on the list but whenever i click on it, the only option is to unpair.

Try deleting and re-establishing a connection. I had to do this with my car system the second time I used it. It seems to work fine after that..

I'm having a somewhat related issue....
I can pair my BT headset, but each time I turn it off and back on I have to manually "Connect" it. It stays in my Devices list, but it will not automatically connect when it sees the headset. Instead I have to touch-hold the device and choose "Connect".
That's a pretty annoying extra step. With my Droid, all I had to do was turn on the headset and then the Droid would see it and connect automatically.

I am having this same problem. Anyone find a solution to this?

I had the same problem while importing contacts from my Touch Pro. I somehow managed to import though.

Strange but true,,,,,
All of my previous WM units, and I had most of them, had BT troubles, but the incredible has been the first device to work correctly with all of my toys. I have a Moto HT-820 stereo HS, a BT mirror in 1 car, Scala Rider BT on my bike, Kenwood system in my other car, and all work, I even made the thing transfer my contacts list from my TP 2 ;-)

Same issue here with my Atrix to my G-Tablet.
I have been all over the Google and nothing but unresolved threads out there.

I have only gotten BT pairing issues with gingerbread roms, not froyo. Are these other folk having bt issues on gb, and perhaps not froyo?

i have a stereo blutooth headset i have had it for little over a year and have used it with a couple older phones(non android) and i would always be about to just turn on headset and it would connect, when i got the dinc and tried to use my headset it would sometimes only connect to the music part or the phone part or sometimes not at all.
i found that if i turn my headset on first, then turn on the blutooth on the dinc it will connect right up no problems at all, this is completely backwards from way i have always done it but it works so i just use wiget to turn off bt if it is on on the phone, then turn on headset then turn widget back on and bingo! not sure if this will work with car or computers but as far as headset it seems to be the way to go!
hope this helps.

Yeah, wow problem ...

Well, still, this unit - a miracle!

very very much!

Music through Aux with Bluetooth [RESOLVED]

I'd like to keep bluetooth on in my car for taking calls, but the phone seems to automatically output audio through that as well, even if a 3.5mm cable is connected. I searched through the settings to no avail. Is it possible to use BT strictly for calls while still outputting music through aux? I mostly listen through Pandora, and I'm on CM7.

I forgot about this post, but it looks like it didn't get any replies. Bump!

Bump

Solution
Yes, it is possible, while connected to your car,
go to settings, Wireless & networks, Bluetooth settings,
search for your car's Bluetooth name and long press it, this should show you a "pop up" window,
click on "Options...", there you have something called Profiles which allow you to control the behavior of that particular Bluetooth device,
You should have 2 boxes ticked, Phone and Media,
tick media off and your device will only work for calls!
Hope it helps!
Best Regards,
P.S: If your phone connects via Bluetooth to your car and streams music, than I must assume your car supports A2DP, in which case, you will gain nothing of audio quality for using the aux input... just saying.

Oh man, thanks so much. I can't believe it took this long to get this straightforward of an answer. I'll have to try it out today.
As far as the audio quality goes, I feel like there's a subjective difference; some sort of flakiness or bits of static when going through BT. But maybe it's just a placebo effect; I'll do some more trials.

Well, it's not impossible.. You could have a low quality Bluetooth receiver but since it is built in with your car it seems unlikely.. either way, what matters is you get your solution and your peace of mind! (I know how I get when something like this happens and I can't figure out a solution! xD)
Don't forget to post back.
Best Regards,

Yep, works flawlessly. I haven't done enough testing to see whether my car sees audio differences between aux and BT, but I'm at least able to use aux separately if I find a difference.

Better control of auto Bluetooth connections?

My g3 is completely stock like my last few phones have been.
I am looking for better control of my Bluetooth connections that automatically connect to various objects. All 3 of my connections have call audio capabilities, and I only want to use 1 for call audio. However when I get in the car its a 50/50 gamble of what will connect to my phone as the priority device resulting in me having to go change the settings every time I drive.
Here's the situation:
My car has 3 BT connections I currently use when I drive.
Priority 1: Car OEM Bluetooth connection. No audio streaming available so all I want is automatic connection for hands free through my car speakers and steering wheel controls for phone calls.
Priority 2: Garmin GPS traffic. My GPS uses an app on my phone to get traffic reports. It only needs the BT connection to communicate with my app. The problem is My GPS has hands free call audio also, but i dont use that feature and never want to. However it seems I frequently have to go uncheck the box "use call audio" in phone BT settings because this sometimes connects to my phone before the car BT does.
Priority 3: sometimes when I am not using my iPod for music I use an adapter for streaming music since my car does not offer that feature on its BT connection. Of course this adapter also offers call audio and media streaming. When this is plugged up and listening to music I have to disconnect my cars BT (listed as priority 1) as it will cause static in my music streaming. When I use this device I shut off the connection to my car and just leave the GPS (priority 2) and this connected and make phone calls by hand without hands free since this adapter does not allow me to use my steering wheel controls etc that the car has and its just easier to do it by hand. I don't always use this adapter, only when im board of my iPod and sirius and want to stream Spotify.
I've tried "Bluetooth auto connect" application but it hasn't done anything to help control which device connects and which doesn't or which of them has priority. A lot of the times I'll get in the car and disconnect all of them and start over but usually one of the devices automatically tries to reconnect causing them to interfere with each other while I'm driving. Unfortunately none of these devices have the ability to shut off features in the devices themselves which means I have to use my phone to control them.
Is there any way of controlling my bluetooth connections in more detail or am I just stuck with them battling each other every time I get in the car? Usually I don't have a problem once they are all set but if my phone restarts or I I need to start all over. If the phone would just remember which connection uses "media audio" or "call audio" this all could be avoided but the phone never ever remembers and always resets them all as checked. My Bluetooth is usually always turned on (probably what kills my battery) and I have no other connections besides what I use in the car. I had the same problems on my Xperia Z1 and don't think this is an LG G3 specific thing. I think its an android thing in general.
Thanks for any ideas.
