Re: [Linphone-developers] Linphone Bluetooth Headset Addition

[Sylvain Berfini]

Hi,

Thanks a lot for your patch, I just merged it into our repository, on the newUI branch, commit id 0cee0e357b568a0692d425701c4abf6c0960191f.
For your issue, I guess it's device related, I don't have the problem with mine.

Regards.

Hello dear Linphone community,

In this mail, i want to tell us, how to add Bluetooth support into linphone for android. In my project, I have tested code on samsung galaxy tab 7.7"(p6800). 

The changes are below.

1- In LinphoneManager.java File

-> Method routeAudioToSpeakerHelperHelper

private void routeAudioToSpeakerHelperHelper(boolean speakerOn) {

boolean different = isSpeakerOn() ^ speakerOn;

if (!different) {

Log.d("Skipping change audio route by the same route ",

speakerOn ? "speaker" : "earpiece");

return;

}

             //add below

if(mAudioManager.isBluetoothScoAvailableOffCall()){

mAudioManager.setBluetoothScoOn(true);

mAudioManager.setBluetoothA2dpOn(speakerOn);

mAudioManager.setMode(AudioManager.MODE_IN_CALL);

mAudioManager.startBluetoothSco();

return;

}else{

if (Hacks.needGalaxySAudioHack() || sLPref.useGalaxySHack())

setAudioModeIncallForGalaxyS();

if (sLPref.useSpecificAudioModeHack() != -1)

mAudioManager.setMode(sLPref.useSpecificAudioModeHack());

if (Hacks.needRoutingAPI() || sLPref.useAudioRoutingAPIHack()) {

mAudioManager.setRouting(

MODE_NORMAL,

speakerOn? ROUTE_SPEAKER : ROUTE_EARPIECE,

AudioManager.ROUTE_ALL);

} else {

mAudioManager.setSpeakerphoneOn(speakerOn); 

}

for (LinphoneOnAudioChangedListener listener : getSimpleListeners(LinphoneOnAudioChangedListener.class)) {

listener.onAudioStateChanged(speakerOn ? AudioState.SPEAKER : AudioState.EARPIECE);

}

}

}

2-Add permission to AndroidManifest.xml File

    <uses-permission android:name="android.permission.BLUETOOTH" />

Then Bluetooth headset can be used.

Issue:

Mic is hearing low by receiver.But, it may be caused by device.

Thanks linphone team.
