How to get valid Bit Error Rate or Rx Qual
<p>I am trying to get bit Error rate by using getGthe following coding but i am always get -1 only. Do  you anybody have idea to get valid Bit Error Rate. please help to get correct value.</p>

<p>The code are following.</p>

<pre><code>public class GetGsmSignalStrengthActivity extends Activity {

        TelephonyManager        Tel;
        MyPhoneStateListener    MyListener;
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Tel  = ( TelephonyManager )getSystemService(Context.TELEPHONY_SERVICE);
    Tel.listen(MyListener ,PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
   }
   private class MyPhoneStateListener extends PhoneStateListener
   {
     @Override
     public void onSignalStrengthsChanged(SignalStrength signalStrength)
     {
      super.onSignalStrengthsChanged(signalStrength);
      TextView dummy1 = (TextView)findViewById(R.id.textView5);            
      String x,m ="";            
          x=String.valueOf(signalStrength.getGsmBitErrorRate());
          dummy4.setText("Bit Error      : " +x);

     }

  }
}
</code></pre>
