EventListener not working once stop is called.

[sandeepReddyG]

I am using the Recording module to stream data to PC over websocket as below. But the data is getting sent only once. If I press start for the second time , keypress in sent to PC but no voice data sent as the eventlistener not getting called. What am i doing wrong here?

import React from 'react';
import {Component,Text,View,Button, Alert } from 'react-native';
import Recording from 'react-native-recording';

export default class VoiceScreen extends React.Component {
constructor(){
super();
this.state={
status:true
}
}
componentDidMount(){
//await this.checkPermission();
Recording.init({

  bufferSize: 640,

  sampleRate: 16000,

  bitsPerChannel: 16,

  channelsPerFrame: 1,

})

Recording.addRecordingEventListener(this.DataHandler);

ws.onmessage=(m)=>
{
  console.log(m.data +"status "+this.state.status);
  if(m.data=='READY')
  {
    this.startVoice();
  }
  else
  {
    this.stopVoice();
  }
}

}

startVoice(){
Recording.start();
}

stopVoice()
{
Recording.stop();
}

DataHandler=(data)=>{

  console.log(" Sending auido data of len "+data.length*2);
  var pcm_len = data.length*2;
  //data.unshift(pcm_len>>8);
  data.unshift(pcm_len);
  data.unshift(0x03);
  var view = new Uint16Array(data);

  //var view1 = new Uint8Array(view);
  ws.send(view);
  data.pop();
  data.pop();

}

sendVoiceKeyPress(){

cmd = [];
cmd.push(0x04);
cmd.push(0x00);
cmd.push(0x05);
cmd.push(0x00);
cmd.push(0x56);
cmd.push(0x4F);
cmd.push(0x49);
cmd.push(0x43);
cmd.push(0x45);
start_speech = new Uint8Array(cmd);
ws.send(start_speech);

this.setState({status:false});

}

sendVoiceKeyRelease(){
this.stopVoice();
cmd = [];
cmd.push(0x05);
cmd.push(0x00);
cmd.push(0x05)
cmd.push(0x00);
cmd.push(0x56);
cmd.push(0x4F);
cmd.push(0x49);
cmd.push(0x43);
cmd.push(0x45);
stop_speech = new Uint8Array(cmd);
ws.send(stop_speech);
this.setState({status:true});

}

componentWillUnmount() {

//Recording.stop()

}

render() {

return(
    <View>
   {this.state.status?<Button title='start' onPress={()=>this.sendVoiceKeyPress()}/>:<Button title='stop' onPress={()=>this.sendVoiceKeyRelease()}/>}
   </View>
)

}

}

From my understainding of android code, Recording.init() again to retake after Recording.stop(). Recording.stop() sets audioRecord = null^[1], so you have to create AudioRecord instance again by calling Recording.init()^[2] before calling Recording.start() again. iOS should behave in the same way.
