            // TODO Auto-generated method stub
            /*
        byte[] data = passing[0].toString().getBytes();
        int size = Integer.parseInt(passing[1].toString());
        int id = Integer.parseInt(passing[2].toString());*/

            TestReceive ra = (TestReceive)r[0];

            //  System.out.println("res val "+bytArrayToHex(data));
            //  System.out.println("func enter : "+ra.ids);
            func(ra.data,ra.size);
            //  System.out.println("func exit : "+ra.ids);
            ra = null;

            return null;
