How to make Bluetooth status visible

Hii, i need to make the bluetooth status visible in the app, i am using this Code

/** * ControlP5 ScrollableList * * replaces DropdownList and and ListBox. * List can be scrolled by dragging the list or using the scroll-wheel. * * by Andreas Schlegel, 2014 * www.sojamo.de/libraries/controlp5 * */ import android.content.Intent; import android.os.Bundle;

import ketai.net.bluetooth.*;
import ketai.ui.*;
import ketai.net.*;
import oscP5.*;

import controlP5.*;
import java.util.*;





KetaiBluetooth bt;
String info = "";
KetaiList klist;

ArrayList<String> devicesDiscovered = new ArrayList();
boolean isConfiguring = true;

int rectColFactor = 0;

//****************************************************************************
// The following code is required to enable bluetooth at startup.
//********************************************************************
void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  bt = new KetaiBluetooth(this);
}

void onActivityResult(int requestCode, int resultCode, Intent data) {
  bt.onActivityResult(requestCode, resultCode, data);
}

//********************************************************************

void setup() {
  size(displayWidth, displayHeight);
        orientation(PORTRAIT);
        background(30, 30, 30);



   //start listening for BT connections
     bt.start();

}
//****************************************************************************
void draw() {
  enableBT();
  getInfo();
}
//*************************************************************************

//**************************************************************************************
void enableBT(){
 if (isConfiguring)
  {
    //-------------------- This stuff is for us to select the intended device
    // ketai lib's UI list is used

    ArrayList names;
   //background(255, 0, 0);
     klist = new KetaiList(this, bt.getPairedDeviceNames());
   isConfiguring = false; // make the "configuring" status false as we have successfully configured

  }

}

//**************************************************************************************

void getInfo(){

  if (!isConfiguring)
  {
  //After configuration everything happens here

    //first set a new background to say we are connecetd
    background(255, 255, 0);


  }
}

//*************************************************************************************
//****************************************************************************************************************************
//---------------------- For killing the list after you've selected a device to pair

void onKetaiListSelection(KetaiList klist) {
  String selection = klist.getSelection();
  bt.connectToDeviceByName(selection);
  //dispose of list for now
  klist = null;
}

//------------------------ Call back method to manage data received
void onBluetoothDataEvent(String who, byte[] data) {
  if (isConfiguring) {
    return;
  }
  //received
  info = new String(data);
  rectColFactor = Integer.parseInt(info);
}
//******************************************************************************

i tried with an If statment or boolean function in the void enableBT() Function, in the getInfo(), and in the void onKetaiList Selection function, by drawing a red or green ellipse , but i have always same result , if i am connected or not,

does anyone have an idea?
