I use a BT A2DP headset with route planners Sygic and Navigon running on a HTC Flyer tablet with Android HC. With every spoken instruction the first 2~3 seconds are lost because of some delay when audio is started. I know for sure that this delay is not in the headset.

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'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 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 Relatedis there a way to disable A2DP streaming audio on the HTC INC? Obviously, I would prefer to play my music thru my car stereo via AUX cable, rather then streaming via my bluetooth speaker.I already spoke with tech support for my new BlueAnt S4 and they said there is no way to disable it via the speakerphone. Hopefully, there is a way to block it on the phone directly.

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?
I just started Pandora up on my shiny new Epic but the audio does not stream to my BT headset by default apparently and I cannot figure out how to make it so. I have the new Blueant Q2 and have been streaming music on my Palm Pre prior to today.

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 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!
It seems that this question has been asked before, I just would like to know whether there is an update in Android.I plan to write an audio application involving low delay audio I/O (appr. < 10 ms). It seems not to be possible based on the methods proposed by the SDK, hence is there - in the meantime - a way to achieve this goal using the NDK?
View 1 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 RelatedI didn't find an API to detect if a Bluetooth A2DP is connected. Can somebody point me out how to check? It looks like if I route audio to Bluetooth A2DP without check, the sound will be routed anyway, and the speaker is turned off.
View 2 Replies View RelatedI 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.
Is this a hard or soft limitation?Will the new roms support all bluetooth profiles?Also, is there any way to pipe my music to my Jawbone 2?I know my previous 8525 winmo I had to load a app to pipe sounds to the headset.
View 5 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 RelatedI've started to recognize a peculiar problem. During a phone conversation on my Hero, I will start talking, and the other person will start talking just after that (maybe a second or two), then they stop, as they apparently now hear me "interrupting" them. In other words, to them, they started talking first, then I start but to me, I started talking first! (No, I am not purposely interrupting them) It's hard to describe, but it seems that there may be a delay in my audio getting to them. It seems to happen with all callers. Did I make this clear? Now, I am wondering if this happens when I am away from home as well, as I use an Airave device at home. Does anyone else experience this? Does anyone have a suggestion on how to test this? Or a solution?
View 8 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've got a conundrum that I can't seem to work out from Googling. I suppose I will give the background then my question.
I use my xperia z2 tablet at the gym to watch TV shows because the treadmill is even more uninteresting than the landscape around my place. I don't like to be hooked up to it via headphones because I don't want to accidentally pull it over. So - I use a bluetooth audio receiver I plug my headphones into, and they receive the audio from the tablet (which is paired with the receiver).
I would prefer to just use my phone in place of the receiver, because the receiver is cheap and doesn't work so well (and i cant believe it can't be done).
I thought two options could be:
1 using the phone as a bluetooth receiver, or
2 somehow using the wifi hotspot on the phone to enable the audio from the tablet to play through the phone.
Does something already exist or is it even possible?
I've just bought a great Bluetooth Speaker to use with my Nexus 4 and it works great. Because it was fairly cheap I went and got another in the hopes that I could connect both speakers to my N4 and output audio simultaneously to both speakers at the same time. I quickly discovered this isn't currently "working" or even possible.
After a lot of Googling, I found an app on the Play store that supposedly let me connect both at the same time but it doesn't output audio to both speakers (I get "static" from the second one). There are also conflicting opinions about whether this is even possible with the current Bluetooth spec although it does mention multicast support and all I could find are various workarounds that involved using a secondary bluetooth transmitter etc.
Any software/hack (root needed or otherwise) that would allow configuring audio to be streamed/output to two connected bluetooth speakers simultaneously? Others have suggested it for use with bluetooth headsets.
Today we can make calls connecting through Bluetooth on car, and have the sound on car's loudspeakers.
Is it possible to send music, or a podcast, the same way?
