Hello,

I´m trying to connect to RFID Reader 8500 through "RFIDAPI3Library" but when I use the Class Readers it doesn´t found any device.
My code is like this:

import android.os.AsyncTask;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.zebra.rfid.api3.ENUM_TRANSPORT;
import com.zebra.rfid.api3.InvalidUsageException;
import com.zebra.rfid.api3.OperationFailureException;
import com.zebra.rfid.api3.ReaderDevice;
import com.zebra.rfid.api3.Readers;
import java.util.ArrayList;
import com.zebra.rfid.api3.RFIDReader;

public class MainActivity extends AppCompatActivity implements Readers.RFIDReaderEventHandler {

   @Override   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  Readers readers= new Readers(this, ENUM_TRANSPORT.BLUETOOTH);
(I change this variable to "ENUM_TRANSPORT.SERVICE_SERIAL" but it throw another Exception)

  ArrayList availableRFIDReaderList = null;
   try {
  availableRFIDReaderList = readers.GetAvailableRFIDReaderList();
  ReaderDevice readerDevice = availableRFIDReaderList.get(0);

  RFIDReader rfidReader = readerDevice.getRFIDReader();
  rfidReader.connect();
  } catch (InvalidUsageException e) {
  e.printStackTrace();
  } catch (OperationFailureException e) {
  e.printStackTrace();
  }catch (RuntimeException e){
  e.printStackTrace();
  }
  }
   @Override   public void RFIDReaderAppeared(ReaderDevice readerDevice) {

  }
   @Override   public void RFIDReaderDisappeared(ReaderDevice readerDevice) {

  }
}

With ENUM_TRANSPORT.BLUETOOTH it founds zero device
With ENUM_TRANSPORT.SERVICE_SERIAL it throw "RFID service is not installed or available Failure in resolving dependency"

The Zebra RFID Reader device is already paired with the phone.

Please, I need some help because is hard to find solutions about this on web and when I run the program in the app "Zebra RFID API Mobile"  it throws the same Exception.

Thank you very much for your answers.
