Hi all,

I'm creating an application to read the data from Nonin 3150 bluetooth device in C# VS 2008. However, the output of the data is not in a readable format (Strange format) Please kindly guide me on how do I change the format so that end user able to see the output.



Here's the code to read the comm port.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;


        private delegate void setTextDeleg(string text);
        public delegate void myDelegate();

       

        SerialPort serialPort = new SerialPort();
        

        private void Form1_Load(object sender, EventArgs e)
        {
            string[] portname = SerialPort.GetPortNames();
            foreach (string name in portname)
                comboBox1.Items.Add(name);

        }

        private void button1_Click(object sender, EventArgs e)
        {

            if (this.comboBox1.SelectedIndex == -1)
            {
                MessageBox.Show("Please select comm port first!");
            }

            else
                if (serialPort.IsOpen)
                    serialPort.Close();

            try
            {

                {
                    serialPort.PortName = comboBox1.Text;
                    serialPort.BaudRate = 9600;
                    serialPort.Parity = Parity.None;
                    serialPort.DataBits = 8;
                    serialPort.StopBits = StopBits.One;
                    serialPort.Encoding = System.Text.Encoding.ASCII  ;
                   
                }

                serialPort.Open();
                label1.Text = comboBox1.Text + " is opened";
               // textBox1.Text = 
                
                serialPort.DataReceived += new SerialDataReceivedEventHandler(datareceived);
               
            }

            catch (Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }

        void datareceived(object sender, SerialDataReceivedEventArgs e)
        {
            myDelegate d = new myDelegate(update);
            textBox1.Invoke(d, new object[] { });

                    }

        public void update()
        {
            textBox1.AppendText(serialPort.ReadExisting());
            textBox1.ScrollToCaret();
        }
    }
}

Thanks much!

Cheers~
