I 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.

In 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'm new to Bluetooth programming and I was wondering if I had a Bluetooth headset that was paired to an Android phone. What's the best way to detect that a button was pressed? Are there modifiers to tell which kind of button it was (e.g. volume up/down, main button) or what kind of press it was(regular, long press etc).

Using Android 2.0 SDK. Is it possible to direct the TTS engine's output to a connected BT headset? I've tried with KEY_PARAM_STREAM set to all of the available stream types but the speech is still output by the speaker on the phone.

There has been one thread talking about Bluetooth headsets and it did not receive many replies. There have been a zillion threads about the Moment's difficulty in connecting via Bluetooth ("Paired but not connected").
If your Bluetooth headset works great with the Moment (e.g. connects consistently, good sound quality, etc.) Please post the manufacturer and model in this thread. Likewise, if your headset stinks, that is probably good information also, so post that too.
Lately, I have had a lot of issues with my bluetooth headphones (won't start on the countless other issues). Out of no where it will stop working; so I go into my bluetooth settings and the headset says it is still connected.... (not the issue)
The issue is when I try disconnecting then re-connecting, the message "Headset is disconnected" appears and will not go away under any circumstance. It stays there when going back to the home page, putting the phone to sleep and back on, everywhere, even when reconnected!
The only way to get the message to go away is powering off the phone. I have repeated this several times with the same results 100% of the time.
I have 9xxBackBeat headset. I connect my headphones to phone, but still the sound comes from the phone speakers. Why?

View 27 Replies View RelatedWhen I had my Voyager, I could use my bluetooth earpiece to talk on the phone, and also get the audio from the Navigation to come through the earpiece. I was surprised tonight that when I was using my GPS on the Droid it didn't come through my earpiece which resulted in me turning my radio down significantly so I could hear the phone.
I also have a stereo bluetooth headphones that I already paired and see the icon on the screen, but when I play a video or some music, it doesn't come through the headphones. Its still coming out of the Droid's phone speakers. Its showing that it is connected in my notifications bar too.
Gonna get a headset soon. Can u still use your phone for say playing games whilst talking.

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.

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.
im 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 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.

View 14 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).
Using Intent.ACTION_HEADSET_PLUG, my app can be notified when a wired headset is plugged or unplugged. But how can it determine whether or not it's plugged in when it starts running? The closest thing I can find is AudioManager.isWiredHeadsetOn() which "checks whether audio routing to the wired headset is on or off" - but the headset can still be connected without audio being routed to it.

View 1 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.
