Neckband microphone is not working in react-native-incall-manager

Issue

I am trying to create a video calling application using react-native-webrtc and when a call starts and my phone is connected to Bluetooth headphones it always uses my Android phone microphone instead of Bluetooth headphones

Does anyone know how to fix this problem, how do I use the microphone when my Bluetooth headphones are connected

Solution

I also faced this issue, I added a plugin to manage audio routes and add some permissions for Android in the XML file

Android required permissions for video calling app

<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="33" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="33" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.MICROPHONE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

Call this code when your WebRTC stream starts it will choose audio route

import HeadphoneDetection from 'react-native-headphone-detection';

    HeadphoneDetection.isAudioDeviceConnected().then(async(e) => {
          if (e.audioJack) {
            console.log("i'm wired headset");
            InCallManager.setForceSpeakerphoneOn(false);
            InCallManager.chooseAudioRoute("WIRED_HEADSET");
            InCallManager.start()
          }
          else if (e.bluetooth) {
            console.log("i'm bluetooth headset",);
            InCallManager.setForceSpeakerphoneOn(false);
            InCallManager.chooseAudioRoute("BLUETOOTH");
            InCallManager.start()
          } else {
            console.log("i'm others");
            if (isHangUp) {
              InCallManager.setForceSpeakerphoneOn(false);
              InCallManager.stopRingback();
              InCallManager.stopRingtone();
              InCallManager.stop({ media: 'video', ringback: '_BUNDLE_' });
            } else {
              InCallManager.setForceSpeakerphoneOn(true);
              InCallManager.stopRingback();
              InCallManager.stopRingtone();
              InCallManager.chooseAudioRoute("SPEAKER_PHONE");
              InCallManager.start({ media: 'video' });
            }
          }
        });
