A2DP Blueooth Car Stereo won't reconnect to mobile

A2DP Blueooth Car Stereo won't reconnect to mobile
I have the Pioneer DEH-P9800BT Bluetooth Head Unit in my car, which supports stereo BT music streaming from any A2DP device.
I also have the HTC TyTN II Mobile which supports the same.
I have paired the two devices, and on the initial pairing successfully played music from the HTC through the Pioneer. When that worked, the BT Audio icon appears in the title bar of the mobile (headphones with a musical note in the middle).
However, after switching off the car and later returning, I have 2 issues:
1) It is impossible to reconnect the BT stereo music playback, unless I delete the Pioneer device from the list of BT devices within the mobile phone, then pair them again. Nothing else seems to work. Simply, I just want all music to be routed through the Pioneer whenever it is in range of the mobile.
2) I have set the mobile phone as "Phone 1" in the Pioneer, and have enabled "Auto Connect", yet it does not auto connect. Every time I get in the car I have to manually scroll to Telephone>Function>Connect Phone>Phone 1. You can imagine what a laborious pain that is compared to my previous 5 year old Nokia Bluetooth Car Kit which just auto-connects whenever my mobile is in range.
Are you able to solve either problem?

Im having the same problems with my sony DR-BT10CX and Moto HT820 whenever i turned either devices off. But whenever i turned them back on, i usually uncheck and recheck the headset whenever i want to use A2DP. It's a pain but i never had to re-pair my device with my tilt.
Try unchecking/checking the bluetooth device instead of re-pairing them (although in your case, its a PITA).
Have you tried updating the firmware on the Pioneer (if its possible anyways).

I have an ATT Tilt w/ the my customized HTC rom. But my JVC BT1 never has any problem to reconnect to my phone.

1) I found a program called A2DPToggle which provides an on/off button on the home page to solve this
2) I found I have to leave the phone in 'visible' Bluetooth mode for auto-connect to work. Less secure, but solves the problem

While this may not help, while messing with my Audio linking between my pda and pc , The PC BT adaptor would freeze if I tried to stream an AAC file or a non mp3 file. It would play it for 10-15 seconds then freeze. I imagine not all mp3
s are created equal for BT purposes either.

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).
Cheers,

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.

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 is somewhat broken.....

I have to unpair and repair my Bluetooth headset every single time I use it. (phone audio only). Looks like Samsung really borked up BT.
Thinking about upgrading to MDL this weekend to see if that fixes it.

i dont know about bluetooth with car, but i listen to my bluetooth headphones every day at work for hours and i have had no probs whatsoever with my bluetooth. it paired really easy like too easy and that was it.

I guess thanks for the fact that at least it works manually so in my case its a 100% software issue.

I'm having no issues with phone or media when hooked up to my car.

I have the same problem with my Denon aftermarket head unit.

My Motorola BT headset pairs ok, but the quality of the audio is so bad to my callers I can't use it. On my S3 it sounded fine. I had to switch to a different headset that's giant and stupid.

2011 Hyundai Sonata

have a jabra headset and its paired excellently 100% of the time
Had minor issues (device based) when it was "paired" to 2 devices.

Use Bluetooth Auto Connect from play store. I was having the same problem except mine connected on to media instead of phone. That app fixed it right up.

Mine will drop connection intermittently to my VW RNS-315 head unit and also drop connection to my Jawbone Icon HD. When it drops the Jawbone I often see a message on the screen that says Bluetooth Sharing has crashed. Not sure if this is as a result of the rooting process or if it's a glitch in the latest firmware. Hoping Samsung will fix and T-Mo will release patch soon.

Have yet to have an issue here with my S4 and my JVC Arsenel (Dont remember which model #, was one of the higher single DIN units a year ago though), use it daily and it connects on its own without issue / hassel both phone and media

I experience the same phone only problem with my Ford Sync system, I have to manually check Media audio, but it pairs both the first tube after unpairing. I'll try the Play Store app and report back today. I will say is nice to see voice control over bluetooth has been fixed in Jelly Bean.
UPDATE: Bluetooth Auto Connect (The first one listed in a Play Store search by Jakub Klos) works flawlessly to connect Phone and Media audio. Thanks @Sym_Link!

No problems with bluetooth here, my Pioneer radio in my Grand Marquis, both audio and phone sync flawlessly. However, my Sony unit in the Saturn, will sync the phone no problem, but I still have to manually check the box to sync with audio.

My experience w/ BT audio has been variable. I have an aftermarket head unit installed on a '05 Acura RSX (JVC-NSX1 - http://www.crutchfield.com/ISEO-rgbtcspd/p_105NSX1/JVC-KW-NSX1.html).
Note: my headunit also utilizes MirrorLink...which is just flippin' awesome.
BT Media audio seems to be very app dependent. I use Grooveshark and Play Music for my day to day listening, and I find that my Grooveshark will auto-play when BT Connects but if I'm going from a fresh power cycle of my automobile to Google Play I have to start the app on my phone prior to accessing the in-dash controls on my head unit.
Other times I can just select in dash controls and it will play Play Music.
Ironically, since the iOS 6.0 update plugging in the GF's iPhone no longer plays audio (freaking Apple). So if she wants to stream media it's only available over BT. Ah, progress!

[Q] Bluetooth reboots Note 8

I have an AT&T Samsung Galaxy Note 8 LTE. I connect to it using a bluetooth headset (listen to tunes while on my commute) and my FitBit One.
The FitBit One doesn't exactly "pair"...I don't know how it works really...I think it's that new Bluetooth LE thing...
My Bluetooth headset does pair and it works great...in fact both devices work fine.
Except when I don't use my headset for several hours. When I get to work, I disconnect my bluetooth headset and put it on the charger. When I go home, if I attempt a bluetooth connection with the headset, the bluetooth icon on the Note will show blue in color and say "connecting" but it will never connect. The headset makes a "connected" noise and I can manipulate the media player using the headset buttons (next/previous song, raise and lower volume, pause music) but the audio will be coming from the Note's speakers.
Now here is where it gets weird...I can stop the bluetooth service just fine. But if I turn it back on again, the Note will reboot. In fact, if I do anything to any of the radios...WiFi, LTE Bluetooth, the note will reboot.
Has anybody experienced something similar with this device..or perhaps another Samsung device?
Thanks

Can't say I've experienced it. Are you rooted/have a custom ROM? If not, have you tried a factory reset?

[Q] Bluetooth connecting to 2 devices at once (1 for audio, 1 for phone), possible?

Is it possible to connect the HTC One M8 to 2 bluetooth devices at once?
I want to connect the Bluetooth A2DP stereo headset to my car, and the hands-free phone connectivity to a Bluetooth headset.
I've gone in the Bluetooth profile on my phone and changed the car setting to NOT do phone, and I've changed the bluetooth phone headset to NOT do audio. Is there anything else I have to do to make this work?

It should work, don't think anything else is required.
I did the same with my note 2, not tried with the M8.
Only difference might be that my bluetooth headset was a basic one and thus could only connect to phone. So I into needed to make the change in the car BT options and remove media keeping only phone selected.
Hope yours works

Yes, do it daily. N7 and m8

Quick question though, can you bluetooth a keyboard to your phone as well as a speaker?
