I am completely new to bluetooth app development. what exactly is a bluetooth profile? is it a hardware specification for the device? can an android mobile phone with bluetooth act as sender and receiver in A2DP profile?

Does 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 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!
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.

This would effectively be the same behaviour as plugging in a regular stereo audio cable/earphones to the 3.5mm jack. Music and call audio are routed out over the headphones, but in order to talk you have to use the phone mic.
I know there's an app that does the reverse (forces stereo media audio over the Headset profile). [URL]

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?

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?
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?

Garmin won't do anything, I've already talked to them, are there any adjustments or setting on the droid that I can try to make this work, I'd really like to get Pandora or other audio going thru it.
View 3 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 RelatedI 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 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 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.
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 RelatedI 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 wanted to try and connect to an bluetooth device using the HID profile using an android phone. The phone I'll be using is the vibrant and according to samsung it doesn't support the HID Profile ( http://ars.samsung.com/customer/usa/jsp/faqs/faqs_view_us.jsp?SITE_ID=22&PG_ID=2&PROD_SUB_ID=557&PROD_ID=560&AT_ID=281257 ).
Now my question is this, where does this "profile" reside? Is it on the hardware level or on the software level ( I assume the latter from other sources that I have read ). And if it is the latter, can HID implementation be created using RFCOMM communication over bluetooth (this is the only seemingly viable method I can see in the android bluetooth API).
I just want to make sure I understand the technology before I try and implement something that may not be possible.
I want to develop an application for input device(bluetooth). I would like to use HID profile or SPP. But Android SDK support only A2DP and AVCRP profile. I'll have to wait until the next version is released. I have one question. I think A2DP, AVCRP profile use SPP. is correct? If so, we can use SPP instead of A~~ profiles? I don't know bluetooth api.
View 2 Replies View RelatedI realize that the Blue tooth API is subject to change over time and that the only available profiles are A2DP and AVCRP, but I am really interested about the options I have to develop an application using the Serial Port Profile. I don't really care if the API will later change, this application is meant to be used only by me (I am trying to communicate to a mirocontroller using Blue tooth and the only supported profiles are SPP and GAP). I am going through the /core/java/android/blue tooth/ classes at the moment but I don't see anything that refers to the SPP or otherwise. I am willing to invest time to learn and write a SPP implementation, provided I have someone to guide me. This is valuable to me because I am doing this project as a final year project so I'm not exactly waiting for someone else to do my work. In conclusion, does anyone have any suggestions on where I could start looking and studying to be able to use the SPP in an application?
View 19 Replies View RelatedThe roadmap for cupcake states that it now supports the Bluetooth A2DP & AVRCP profiles. Since the Bluetooth API was ripped out of 1.0 does that mean that these are the only profiles supported? Or are there any other profiles currently supported?
View 3 Replies View RelatedI am trying to use Bluetooth SPP to communicate over it. In some Android phones, SPP profile is not activated. I faced the problem in the application that SPP was not activated and so the connection could not be established over bluetooth and when I started another app that is 3g hotspot which I think activates SPP and I was able to connect over bluetooth in my app.
So, how can we actually activate SPP profile of bluetooth in Android devices? And does all the android devices has SPP profile?
I read somewhere that the Nexus One supported the SPP profile but now this page seems to contradict that : http://www.google.com/support/android/bin/static.py?page=guide.cs&gui....
View 2 Replies View RelatedA friend wanted to know if he could use his android tablet as a headset, and after some searching it looks like quite a few people would like this.
So I was sondering if this is possible, I am new to Android development and I have been playing around with the Bluetooth samples and cannot seem to figure out how to make other devices see Android as a headset.
So my main question is- Is it possible to make a app that would disguise an android device as a headset so it could receive calls and maybe even dial number?
I would like to clarify if this is even possible with the Android SDK
The main use if i make this app is for people who can't afford the data plan that is required when buying a smartphone from a carrier. So if this person has a small android MID they can pair it with their dumb phone and essentially use their MID as a phone.
I use MAP to see texts on my Toyota Camry. It's supposed to be able to read email as well. However, there are times where the MAP settings aren't saving and the look actually changes. In one instance I get this:
With this screen the settings won't save and messages can't be read. If I reset the phone, however, and go back to the MAP settings it will sometimes change to this:
With the setting screen like this, the car can access text messages but not emails. HTC One X using Tapatalk 2
