Bluetooth stream audio to android

How to stream audio from one Android device to another Android device Via Bluetooth?

1. Almost every device supports A2DP, A2DP and HFP(Handsfree) profile are the basic profiles which phone needs. 2. Android 4.2.1 had audio streaming issues over bluetooth, it was a choppy audio which got fixed as per google in latest release. 3. Most of the people earlier had tried on bluez (open source bluetooth)stack but from JB onwards ,bluez is replaced by broadcomm stack. You need to implement audio sink profile in the phone. Audio streaming between 2 devices can be possible using Alljoyn, check link

Thank you for that link @ashish. I am go through that. And will let you know what happens. Thanks again.

Does the audio need to be streamed via Bluetooth? What about using WiFi-Direct? This would actually give you more flexibility and features.

Is it possible to stream audio over Bluetooth?

Below sort of thread says its possibility that streaming audio over Bluetooth is possible between devices but there was question mark on its success rates till Google official announced that We have fixed the a2dp streaming stutter problem on N7. The next release should have the fix. Sorry about the problem.

And does every android device support A2DP?

Support compatibility is mention on Android developers site that its added from API Level-11 with appropriate features. But I came across XDA tread where OP mention problem in Android 2.1 ,means its also support in previous api levels but OP facing issues.

Hope it make sense to understand and I would like to recommend to refer XDA forum to get more information about A2DP compatibility and its sucess.

I my opinion, if A2DP doesn’t work properly, we’d better move to lower layer, and we can create a basic stream which can be used for sending any form of date. I succeed in sending byte stream via Bluetooth between J2ME devices.

If install an app in both devices is acceptable, I’ve sample codes to create a Bluetooth server and a client to communicate with each other via socket, once the socket is established, you can send you audio stream 🙂

// you can generate your own UUID and use it as an port to eatablish a socket private static final UUID MY_UUID = UUID.fromString("20687DAD-B023-F19E-2F60-A135554CC3FD") BluetoothServerSocket serverSocket = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME_INSECURE, MY_UUID); 

now you have the serverSocket, just use it as an ordinary ServerSocket:

BluetoothSocket socket = serverSocket.accept(); 

and then you can get InputStream and OutputStream from this BluetoothSocket and send audio stream just like HttpConnection

assume you already got the BluetoothDevice

// you should implement the method getBlutoothDevice BluetoothDevice device = getBluetoothDevice(); BluetoothSocket socket = device.createRfcommSocketToServiceRecord(MY_UUID_SECURE);

Bluetooth audio streaming between android devices

I made a research on the same topic and found that android devices are a2dp sources and the audio can be streamed only from an a2dp source to an a2dp sink. A2dp sink can be a bluetooth headset or a bluetooth speaker. But my question is then how the android app named «Bluetooth Music Player» works? It allows streaming from one mobile to another. So in this case the listening mobile device must act as a sink. How this is possible? Are they using some other profile instead of a2dp? Ok, that may be a different profile what they are using. Because the application needs to be installed in the client side also. But how it becomes possible to stream voice from a bluetooth microphone to an android device? Please help.

I did not understand what you need to know: sending audio from one Android to another, or sending audio from a standalone Bluetooth microphone to an Android?

Hello Sir, I need your help to steaming audio from one device to another device. Can you please give me any example code for this ? I have asked question : stackoverflow.com/questions/16789394/…

Without knowing details about the mentioned Bluetooth Music Player, it seems to use simple Bluetooth data connection, otherwise you would not need to install a client on playing/sending device.

To stream audio from microphone to another device, you can record it on your sending device and send it to the receiving device. You will need to implement a protocol for that purpose.
OR
You can implement an alternative A2DP sink service. This is, what the sink is: a device with a Bluetooth Protocol Stack with an implementation of A2DP Sink.

Edit:
For the case you detailed by your comments, the sending device should be left as-is, without installing any app. That implicitly means that your solution must make use of out-of-the-box Bluetooth functionality of that Android device.
What you can use here is therefor limited to those profiles that Android typically support, which is HSP, HFP and A2DP. Since you obviously want to stream music, A2DP would be your choice.
On the device supposed to receive the audio stream and do the playback, you have to implement a service providing the A2DP sink as an self implemented BluetoothService opening a BluetoothServerSocket on RFCOMM as described in Android documentation.

You will have to spend much effort implementing this, and I am not sure if you will need a license for this.

How to stream audio from PC to Android Device over Bluetooth

I have a rooted Android Device running Android 2.3 Gingerbread and a PC(with Bluetooth dongle) running windows 7. My mobile has Bluetooth with A2DP support. I want to output the audio(not just music) of my PC to my Android Device over Bluetooth. i.e. I want my android device to work as an Audio Output Device(like headset) for my PC. How to do it?

Dev0 and hello are correct — no you cannot connect using your Android device as a A2DP sink given the standard Android bluetooth stack. Stack Overflow user Dennis Mathews explains why:

You may not be able to [create an A2DP connection] manually between 2 phones also because to stream one device needs to be A2DP sink and other other A2DP source; phones are typically only source devices (source of the stream that can stream to sink devices), sinks are headsets or Bluetooth speakers.

He and the OP briefly discuss options for replacing the stack but their conversation dies without a concrete answer. as it seems several other similar questions around the web do. XDA user zelendel, in general, isn’t very hopeful about the matter — when asked if it was possible to replace the bluetooth stack he responded:

Simple answer is no. You can try a CM based rom that gives you those options but the stacks can’t be swapped due to driver problems. It is a give and take. The Default has better strength and range but is missing a few unneeded option (PO), while CM uses Bluz stack which gives you the option but you lose some BT signal strength and range.

Sorry, it seems to me you’re out of luck.
