I want to add a function to my App, where the user can choose to play the audio on a bluetooth enabled speaker. I have a Parrot Easydrive in my car and this works for phonecalls and for example the Dictafoon App among others. I understand that I should use the Core Audio framework. WHen a bluetooth device is connected it is said that it is easy to stream the audio to that connection. I am now looking for Core Audio sample code (or a book) where connecting and streaming to a bluetooth device with Core Audio is explained. Can anyone shed a light on this? If there is another framework or sample

There are three different Bluetooth related audio port types documented in Apple's AVAudioSessionPortDescription reference. But Apple doesn't explain much about these three types. Can somebody help explain more? AVAudioSessionPortBluetoothHFP | Input and Output This is used when connected to a bluetooth devices through Hands-Free profile, like cars or earpieces. It can be accessed by setting your audio session category to AVAudioSessionCategoryPlayAndRecord and category option AVAudioSessionCategoryOptionAllowbluetooth . AVAudioSessionPortBluetoothA2DP | Output only This is mainly used for

I'm developing a customized embedded device which uses Gingerbread 2.3.4 as an OS. Now the device should be able to play audio streaming from other A2DP -enabled devices such as iPhone or other Android devices. I know that the Gingerbread includes Bluez stack 4.69 which is capable of A2DP sink functionality. However, I doubt that Android exposes these APIs. Do you have any ideas how I can achieve this functionality? Since I'm not developing a generic Android App, any kinds of non-standard method will be appreciated. I think the Bluez stack can be directly accessed through DBus interface even

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

In our app, I'd like to connect to a previously paired A2DP Bluetooth Speaker and direct audio playback to it, using Android v4.2 or later. I can successfully create an A2DP profile object using this code to start the process: /* Manifest permissions */ <uses-permission android:name="android.permission.BLUETOOTH"/> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/> // Get the default adapter BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); // Establish connection to the proxy. mBluetoothAdapter.getProfileProxy(this, mProfileListener, BluetoothProfile

I'm working on an audio recorder app that uses a bluetooth mic to record audio on to an Android device (Nexus 7 - rooted Android 4.4.2). It's currently implemented on HFP and everything is working fine. The bluetooth mic is implemented with Bluegiga's WT32 bluetooth module + a mic input, audio quality via HFP isn't great but it's sufficient for now. However, I'm now trying to change the bluetooth profile to A2dp, since there are two mic inputs (L/R) and WT32 supports A2dp (source). After much research I found that stock Android doesn't support A2dp (sink), and it's possible to modify Android's
