BT connection to RFID reader

I am trying to connect to BT RFID reader using JSR 82

String myServerUrl="btspp://" + device.getBluetoothAddress()+":5;encrypt=false;authenticate=true";

StreamConnectionNotifier notifier =(StreamConnectionNotifier) Connector.open(myServerUrl);

It gives me the following exception SecurityException: Permission Denied.

Is anybody knows something about it?

Ok. I did connected Nokia 6131 NFC to RFID reader and discovered service, but if I try to open connection it throws me exception:

javax.bluetooth master /slave role switch not supported


Service url discovered is:

btspp://000780803xxx:1;authenticate=false;encrypt=false;master=true

StreamConnection conn = (StreamConnection) Connector.open(myServerUrl);



And if I put

btspp://000780803xxx:1;authenticate=false;encrypt=false;master=false

it gave me Permission denied exception.
