Need to modify the code so that when the button on the netduino is pressed, it sends a message to the bluetooth terminal on my android phone.

  public class Program
    {
        public static string outBuff = "";
        static SerialPort serialPort;
        static OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
        public static void Main()
        {
            string portName = SerialPorts.COM1;
            int baudRate = 9600;
            Parity parity = Parity.Odd;
            int dataBits = 8;
            StopBits stopBits = StopBits.One;

            serialPort = new SerialPort(portName, baudRate, parity, dataBits, stopBits);
            serialPort.Open();

            System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
            byte[] bytesToSend = encoder.GetBytes("HHHHHHHHH\r");
            serialPort.Write(bytesToSend, 0, bytesToSend.Length);
            Debug.Print("This is debug print Did you see string sent thru serial port?");
            serialPort.DataReceived += new SerialDataReceivedEventHandler(serialPort_DataReceived);

            while (true)
            {
                serialPort.Write(bytesToSend, 0, bytesToSend.Length);// keep on sending the string out forever
                Thread.Sleep(1000); // wait a bit to give a chance for receiving  a few bytes ...
            }
        }

static void serialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {   // This is woken up upon reception of data from the com1 port, to handle the received data.
            byte[] bufferData = new byte[20];
            if ((serialPort.BytesToRead > 4) && (serialPort.BytesToRead < 20))
            {
                serialPort.Read(bufferData, 0, 20);
                ///convert received bytes to char array
                char[] charArray = System.Text.UTF8Encoding.UTF8.GetChars(bufferData);
                //convert char array to string
                for (int i = 0; i < charArray.Length - 1; i++)
                {
                    outBuff += charArray[i];  //build  the string char by char.   
                }
                Debug.Print(outBuff + "\n");
                if (outBuff.IndexOf("off") >= 0)
                {
                    led.Write(false);
                }
                else if (outBuff.IndexOf("on") >= 0)
                {
                    led.Write(true);
                }
                outBuff = "";

            }
        }    
    }
