daten über Bluetooth übertragen

hallo ;
ich habe ein programm geschrieben für hinderniserkennung über kinect 
Kamera.
ich wollte die entfernung zwischen das kamera und Hindernis über 
bluetooth oder RS232 zu einem Mikrokontroller übertragen.das programm 
ist im visual studio 2010 geschrieben.ich habe versuch mit diesem keinem 
program:

using namespace System;
using namespace System.IO.Ports;
using namespace System::Threading;





namespace System.IO.Ports;
//using namespace System::IO::Ports;
using namespace System.IO.Ports.SerialPort;

 SerialPort Serial;

 Serial.PortName = "COM4";
 Serial.BaudRate = 9600;
 Serial.DataBits = 8;
 Serial.StopBits.One;
 Serial.ReadTimeout = 500;
 Serial.WriteTimeout = 500;

Serial.Open();
 if (Serial.IsOpen)
 {
 Serial.Write("mm",depthMD( point.x, point.y ));
 Serial.Close();


aber leider bekomme ich immer diese Fehler Meldungen:
