Audio input from bluetooth mic

Great plugin. Thanks for that!

Ionic_v4

Trying to record the audio using Bluetooth microphone and play through phone speaker.
I have turned on the Bluetooth SCO using https://github.com/gntikos/cordova-BluetoothSco

recoding :

startRecord() {
    if (audioinput && !audioinput.isCapturing()) {
      BluetoothSco.start(
        function () {
          console.log("Bluetooth SCO on");
        },
        function () {
          console.log("Bluetooth SCO on error");
        },
        { enablePlayback: false}
      );
      this.captureCfg = {
        audioSourceType: 7, 
      };
      audioinput.start(this.captureCfg);
	}
}

Play:

playAudio(data) {
    AudioToggle.setAudioMode(AudioToggle.SPEAKER);
    var audioBuffer = this.audioContext.createBuffer(
      audioinput.getCfg().channels,
      data.length / audioinput.getCfg().channels,
      audioinput.getCfg().sampleRate
    );
    if (this.captureCfg.channels > 1) {
      for (var i = 0; i < audioinput.getCfg().channels; i++) {
        var chdata = [],
          index = 0;

        while (index < data.length) {
          chdata.push(data[index + i]);
          index += parseInt(audioinput.getCfg().channels);
        }
        audioBuffer.getChannelData(i).set(chdata);
      }
    } else {
      audioBuffer.getChannelData(0).set(data);
    }
    console.log("Playing audio..");
    // Create a buffer source based on the audio buffer.
    var source = this.audioContext.createBufferSource();
    source.buffer = audioBuffer;

    // Connect the buffer source before playing.
    source.connect(filterNode);

    // Play the audio immediately.
    source.start(0);
	....
}

I'm able to record through the Phone Mic and play on Bluetooth speaker. Just stuck on this on. Recording through Bluetooth mic and playing on the speaker.

Hi,
same problem here. I cannot record from the bluetooth mic. I tested on Android. Otherwise this plugin is great.

Any luck with this @touficzayed or @Vaibhav1587 ?

Hi @MumblesNZ.

I tried with the bluetoothSco plugin, and testing on one single device only it worked: I was able to record with the bluetooth microphone and listen in the bluetooth headset.

The only drawback is that the audio quality is not very good.
