推荐答案

你好，我需要通过蓝牙发送一些命令。命令如， 

hello, I need to send some commands via bluetooth. The commands like, 

command_1

command_1

command_2

command_2

我试过这个，但是，没有用。我需要发送没有换行符的命令。

I tried this but, Did not work. I need to send those commands with no line breaks.

namespace Smart_Buddy
{
    public partial class Form1 : Form
    {
        SerialPort serialPort1 = new SerialPort();
        private string messege;

        public Form1()
        {
            InitializeComponent();
          
            getAvailableComPorts();

           
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            
        }

        void getAvailableComPorts()
            {
            String[] ports = SerialPort.GetPortNames();
            comboBox1.Items.AddRange(ports);
            }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
              
                    SerialPort serialPort1 = new SerialPort();
                serialPort1.PortName = comboBox1.Text;
                serialPort1.BaudRate = 9600;
                if (serialPort1.IsOpen)
                    messege = "d1_on";
                serialPort1.WriteLine(messege);
                serialPort1.Close();
            }
            catch
            {
                label1.Text = "not Connected";
            }
        }
    }
}
