Bluetooth cant receive proper data

Question

im sending data like "52 40 00 00 CF E6 2A 1 2A 0 0 0 1 0 5 2A 0 0 0 0 2A 0 0 0 0 0 3B 00" from HC-05. but the problem is when i reciving data i get different data. device connected properly, but when i sending data to mobile device im getting wrong data.plaese help me.

here is my code what i did wrong?

    public class MainActivity extends AppCompatActivity implements View.OnClickListener {

here it is

 public class BytesTrans {
public static long[] bytes2HexString(byte[] b, int count) {
    long  receivedData[] =  new long[29];
    String ret = "";
    for (int i = 0; i < count; i++) {
        String hex = Integer.toHexString(b[i] & 0xFF);
        if (hex.length() ==1) {
            hex = '0' + hex;
        }
        String capsHex= hex.toUpperCase();

        receivedData[i] = Long.parseLong(capsHex,16);

        ret += hex.toUpperCase() + " ";
    }
    return receivedData;
}

}

here is the code

 while (true) {

                // Get number of bytes and message in "buffer"
                for (int i = 0; i < buffer.length; i++) {
                    bytes = mmInStream.read();
                    receivedDataArray[i] = bytes;
                }
                long abc[] = receivedDataArray;
                bluetoothIn.obtainMessage(handlerState, bytes, -1, receivedDataArray).sendToTarget();
            }
            catch (IOException e) {
                e.printStackTrace();
                break;
            }
        }
