I have a Bluetooth recevier connected to the head unit in my car. It's paired with my Droid and connects just fine manually, but it won't autoconnect when it sees the unit. My BT headset autoconnects, so I'm not really sure what's different.

I have been experiencing some frustrating audio stuttering or skipping while using A2DP Bluetooth stereo. After a lot of web searching and experimentation, I seem to have found a solution and thought I would pass it along just in case it may be of help to others.First, the problem. I am using a Sprint Samsung Moment Android v 1.5 phone and an Altec-Lansing/Plantronics Backbeat 903 bluetooth stereo headset. This combination has generally been working great so long as I am indoors or in my car. Oddly, though, as soon as I start moving around, especially outdoors -- and especially in a downtown area -- I would begin to get persistent drop outs, stuttering, skipping, etc.Research on a number of websites suggested two potential general sources for problem:
1. A2DP uses most or all of the bluetooth bandwidth and a fair amount of processor; this can create a problem of insufficient bandwidth and/or system resources. A number of sites and posts suggest various approaches based on this notion, most of which involve turning off or shutting down as many resources as possible including wifi, gps, unnecessary applications, or even restarting the phone to clear out such processes. I already do most of this just to try to keep my battery alive through the entire day. But there was one item I had not turned off and it seems to be making a significant difference: Wifi notification. (Menu --> Settings --> Wireless controls ==> Wi-Fi Settings --> Network Notification.)I have run across several theories as to why this would work. Some suggest that when you are walking outdoors (especially in an urban area), the wifi notification function encounters (moves in and out of) a lot more wifi networks and that the stuttering occurs when it is sampling or processing each of these new networks. In any event, turning this feature off seems to have made a significant difference. This seems to make a difference even if you already keep wifi turned off.
2. The other line of potential causes could be a problem with signal strength. One post suggested that bluetooth signals are stronger (or are reflected back) indoors or in a car -- but simply dissipate when you are outdoors. The suggested fix for this (as odd as it may seem) is to simply move your phone to the other side of your body. The purpose here is to avoid the bluetooth signal having to travel through your body. It turns out that Altec-Lansing actually makes this same recommendation on their support page. To my surprise, this also seems to work. The bluetooth receiver on the Backbeat headset is apparently on the left side. Being right handed, I have always preferred to carry my phone on the right. But moving the phone to my left side helped to dramatically reduce the stutters and drop outs I was experiencing with the headset.
These two steps have really helped to solve this problem for me. Using my bluetooth stereo headphones has become a real joy instead of an ongoing source of frustration. I hope this experience can be helpful to others.
I've connect to my bluetooth headset without a problem, but it won't reconnect automatically. I have to manually go and re-connect everytime.

I can connect to the hands free but I have to manualy reconnect everytime I get into the car. I was wondering if there was anyway to get the X10 to connect automatically as all my previous phones used to.

I have an origonal rom on my HTC sensation. I had the same problem with the revolution rom.
It looks like A2DP Stereo Bluetooth support is a recent addition.
Would you folks that know about it expect this to work in the Evo?
I've tried pairing with my Jabra BT620s headphones, with no luck. One time I got the remote control to pause & un-pause the song, but I've never gotten the audio redirected, nor the volume control to work.
Shoud this be in 2.1? Froyo?
Looking to get a new BT headset. I want A2DP so I can listen to media. It's so tough to tell which headsets have A2DP, so I figured I'd post up for suggestions.BlueAnt Q1: Supposed to have some kind of Android specifics, but I couldn't find info. Also, voice control is not my thing.Samsung WEP870: Kind of interested in hearing from someone who has this one. It just might work.Wise and Blue WB130: Found it by luck. Never heard of the company, but reviews were good. Anyone have one?

View 1 Replies View RelatedDoes anyone know if the DI has/uses the A2DP Bluetooth profile? I'm looking for a good Bluetooth stereo earbud set and most say they use A2DP. I checked all the literature on the DI that I could find and don't see A2DP listed anywhere. I searched the forums and found some info regarding the Hero and Motorola Droid, but nothing on the DI. I did read where the Hero with Sense UI had some issues with 3rd party apps and A2DP, but that the native Sense UI music app worked fine. Can someone enlighten me on A2DP and the DI please?
View 2 Replies View RelatedI've tried about a dozen "mono" apps and have found nothing that will do what I want. I have also tried the Droid Incredible and my current phone the GS3. I have a 2011 BMW and for some reason they didn't include a2dp in their stereo system. Nothing I do will force the stereo to play music or notifications, or read out lout texts through the car speakers. The only thing that will go through is phone calls.
I've accidentally discovered something interesting. If I am on a call through Bluetooth in the car and navigating at the same time, the navigation voice will come through the cars speakers as well.So what I need is something to trick the car into thinking my phone is on a call, thus triggering the Bluetooth to transmit phone sounds through the speakers, this way I can use a text message reader, music, whatever.
So the app/hack would need to emulate whatever the phone does with Bluetooth signals when it starts a call. All sounds the phone makes should go to Bluetooth.....which it seems like its already doing while on a call.
I would like to develop a software using Bluetooth A2DP/AVRCP profiles on Android. I could not find the related API on the developer's website at this moment. But, I found a product by Sybase below. http://www.sybase.com/detail?id=1064424 Do we have any other option?

View 2 Replies View RelatedSo far I love my EVO, but one thing that is really driving me crazy. With my Blackberry I had grown accustomed to streaming my music from my phone to a bluetooth stereo gateway in my car and my home.My BB sounded GREAT doing this.But the EVO has a really grungy crackling sound, especially when there is loud high frequency content, such as a lot of cymbals, etc. Some songs sound better than others depending on how they were recorded, but by in large it's very annoying.Even my wife, who is nowhere nearly as picky as I am about sound quality complains about it.I've tried to put up with it, but usually I resort to plugging directly into the aux jack.What a letdown for such an otherwise advanced phone!Is anyone else experiencing this?The research I've done so far indicates the the problem is that Android is locked at a relatively low "bitpool" setting, which is ok for voice, but doesn't provide the necessary bandwidth for decent music quality.Thus far I haven't found way to adjust this.Does anyone know of a solution, or if there is a solution coming? Will this be addressed in Froyo?It just sucks to have to plug my phone in again just to get decent sound quality.
View 8 Replies View RelatedIs there any way that I can disable the A2DP Bluetooth profile on my Hero please? I do not want it to be used for one particular connection, my Bury car kit, but do not mind if it is off all the time. I used to be able to do this in WM with a little app called BTMusic - does anybody know of an equivalent in Android please? I have searched the market without success.
I know I can long press on the connection and tell it not to stream media, which switches off A2DP, but I can't make that stick. Next time they pair it is back on again and I then have to go in and manually switch it off again. A pain when all I want to do is get my sat nav speaking to me when I sit in the car!
I have a bluetooth audio A2DP streamer (a BTT005) which I am using to send bluetooth audio from my telly to something.
The original idea was to transmit this to my mobile phone (samsung galaxy S3), and use the normal headphones on the phone to listen to the telly quietly while I'm working late at night.
For some reason, I can't see any way to pair the a2dp transmitter with the galaxy s3.
There seems to be plenty about sending an audio stream out FROM the S3 to a receiver, but no info about configuring the phone to receive an audio stream IN to it.
(Obviously the other answer is to buy a bluetooth headset to receive the audio stream, but I thought it would be cool to use my phone as the headphones).
I know its possible to send audio from an Android phone via bluetooth to a PC using the a2dp profile. But I want to do it the other way. Connect the phone to my amplifier and send audio via bluetooth a2dp from my laptop.
View 9 Replies View RelatedIn my understand, Anroid app supports only SPP connection not HFP and A2DP. However, I want to initiate HFP and A2DP connection in Android app just like selecting Bluetooth device in Bluetooth Settings menu. I'm not sure it is possible to use a intent including BluetothDevice object, so the intent receiver can initiate HFP and A2DP connection. If you have a idea, could you let me know that?

View 1 Replies View RelatedOne thing that I really like about the phone is the ability to play music from my phone to my car stereo via Bluetooth because it has the A2DP. No wires and I can control the music ON the deck itself instead of the phone. I've updated the phone with the leaked froyo about 2 days after it was leaked. I noticed that I couldn't play music from my phone to my car stereo anymore via bluetooth. I am able to take calls fine via bluetooth while I am driving, it just won't play any music.
View 2 Replies View Relatedim currently looking for the way that my app knows when the phone has being paired and connected to a bluetooth headset device.
I read something about this intent, but not on the Reference documentation of http://developer.android.com
android.bluetooth.a2dp.intent.action.SINK_STATE_CHANGED
Is this actually working, is it officially supported.
I mean, can we just register a broadcastreceiver to handle this intent , check for the EXTRA_STATE string extra to see if it equals STATE_CONNECTED and be sure that the phone is now connected with a bluetooth headset device ?
What about this BluetoothA2dpService class? There is no official documentation about this, everything i found i from code snippets of the android OS source code.
I have a sprint anycom bluetooth reciever connected to my car stereo. I think it only supports the A2DP bluetooth profile (no hfp).Right now the music plays through the car stereo just fine but when I get a phone call it does not. Ideally I would like to have the phone call audio go through the stero and use the phone's microphone as if it were on speakerphone. Is this possible?My phone is a g1 running the latest experimental release of cyanogenmod rom.I would love a built in solution but I think the ability to do that is so non standard it wouldn't exist. An existing marketplace app with the ability would be great, too. I have not done any android development but I am a java developer, so a pointer on how to do it programmatically (or that it is not possible) would be great, too.
View 1 Replies View RelatedI was cleaning all the crap off my phone I don't use anymore and I believe I accidently removed the bluetooth software that allows it to connect to stereo bluetooth headsets. I can control the player with the headset, I can make phone calls from it, but when I try to play music there is no sound.
I was trying to reset the phone using RUU, but it reboots the phone and then says it cannot reconnect after that and the software shuts down. I can still sync with outlook, so my driver is not the issue. I am out of ideas.
Is there anyway possible to reinstall just the bluetooth portion of the rom?
Even registering the broadcast receiver at the highest priority still fails to receive the Bluetooth media button events on the HTC Hero phone. The Bluetooth media button registration code works fine on the other Android phones that I have tested. Apparently this isn't the first time HTC has done something like this, as I also found a report of a similar problem on one of the HTC Microsoft Mobile Devices reported here
It seems extremely short sighted of HTC to code their media player so that it grabs the Bluetooth AVRCP media button events in such a way that other applications are unable to work with the Bluetooth head phone buttons and Bluetooth in car stereo systems.................
Almost a year ago I purchased the HT820 Motorolla headset so I could pair a bluetooth phone and mp3 player to the same headset. It worked fantastic. Now that I finally have my hands on the Google phone, I was hoping to dual pair the headset to the phone for both media and the phone.
I don't know if I am doing something wrong during the pairing procedure, but it will not play media through the headset, except in the second before dialing a contact or just after I hang up. Whatever music is playing, comes out of the speakers, but like I said if a call comes in, I hear the music through the headset until I answer, and then it pauses like it should, then plays again after I hang up but it switches back to the external speaker almost immediately.
It works fine for the phone, and in the Bluetooth list of devices, it shows as connected.
We just got 3G here in Small Town Vietnam. Great except now they can charge us their ridiculous Data rates 3 times faster! Thought is was bad when we had EDGE but way too expensive with 3G. I use DATA THROTTLE to keep my G1 off the data Network most of the day but I connect 4 or 5 times a day to check email and to play around. With 3G that playing around is averaging $7 usd a day! I live on $10 a day here in Vietnam and that's a big expense to me So I am looking for an Auto-Connect WiFi app that will turn on and connect when I walk by a HotSpot. But I have downloaded about 5 apps so far and although they all work when I use them when I put my phone in my pocket it turns off and will not connect. I go under settings and hit the Never Sleep button but they all go to sleep anyway..What WiFi app will Auto connect when the phone is in my pocket as I walk by different HotSpots?

I am fine with this, but it makes the battery die so quickly. Any way I can make my phone auto connect to wifi or mobile web to do the updates, and then auto connect. Also, any decent facebook app that isnt the default one? I have also read that you can set different profiles up for work or home etc.
