发送短信的 AT 命令在 Windows 8.1 中不起作用 [英] AT Commands to Send SMS not working in Windows 8.1

问题描述

我已经研究了两天多，试图制作一个使用 AT 命令发送短信的应用程序，我在网上实施了一些教程和项目.不幸的是，它们都没有奏效.

I have been researching now for more than two days, trying to make an app to send SMS using AT Command, I implemented few tutorials and projects available on web. Unluckily, none of them worked.

[https://docs.google.com/document/d/1VfBbMcKZsutP8Cwg2iu7Rqiyccks1J6N2ZEbkbxnCTU/preview" ] 这段代码让我执行了命令，但没有发送消息.

[https://docs.google.com/document/d/1VfBbMcKZsutP8Cwg2iu7Rqiyccks1J6N2ZEbkbxnCTU/preview ] This code gives me Command executed, but message is not sent.

然后我尝试了另一个项目(我使用的是 C# 和 Visual Studio 2013)，其中包含以下文件，执行后状态更改为 Message Sent，但我没有收到消息.我正在使用 HUAWEI Mobile Connect - 3G 应用程序接口 GSM 调制解调器

Then I tried another project (I am using C# and Visual Studio 2013), which have following files, After execution the status is changes to Message Sent, but I do not receive Message. I am using HUAWEI Mobile Connect - 3G Application Interface GSM Modem

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace CSharp_SMS
{
static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form_SMS_Sender());
    }
}
}

Form1.cs

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

namespace CSharp_SMS
{
public partial class Form_SMS_Sender : Form
{
    private SerialPort _serialPort;
    public Form_SMS_Sender()
    {
        InitializeComponent();
    }

    private void buttonSend_Click(object sender, EventArgs e)
    {
        string number = textBoxNumber.Text;
        string message = textBoxMessage.Text;

        _serialPort = new SerialPort("COM17", 19200);   //Replace "COM7" with corresponding port name

        Thread.Sleep(1000);

        _serialPort.Open();

        Thread.Sleep(1000);

        _serialPort.Write("AT+CMGF=1
");

        Thread.Sleep(1000);

        _serialPort.Write("AT+CMGS="" + number + ""
");

        Thread.Sleep(1000);

        _serialPort.Write(message + "x1A");

        Thread.Sleep(1000);

        labelStatus.Text = "Status: Message sent";

        _serialPort.Close();
    }
}
}

程序有问题吗?我错过了什么吗?或者，在Windows 8.1中运行这个有问题，因为我还发现有一个叫做MS HyperTerminal的程序，我不清楚其中的一部分.

Is there problem in the program? Did I missed any thing? Or, there's problem to run this in Windows 8.1, cause I also found that there is a program called MS HyperTerminal, which part of that is not clear to me.

推荐答案

我使用了AT Commands 以下格式并且它有效.

I used AT Commands in following format and it works.

public bool sendMsg(string smsid, string PhoneNo, string Message, string from, string to)
{
    string recievedData;
    bool isSend = false;
    string text = "Hello " + to + ",
" + Message + "

" + from;
    if (!port.IsOpen)                
        port = OpenPort();
    recievedData = ExecCommand(port, "AT+CMGF=1", 400, "Failed to set message format.");

    try
    {
        //string recievedData; // = ExecCommand(port, "AT", 3000, "No phone connected");
        String command = "AT+CMGS="" + PhoneNo + """;
        recievedData = ExecCommand(port, command, 1000, "Failed to accept phoneNo");
        command = text + char.ConvertFromUtf32(26) + "
";
        recievedData = ExecCommand(port, command, 1000, "Failed to send message");
        if (recievedData.Contains("OK"))
        {
            isSend = true;                  
        }
        else if (recievedData.Contains("ERROR"))
        {
            isSend = false;                
        }
    }
    catch (Exception ex)
    {
        MyLog.Write(new LogPacket(ex, DateTime.Now));
    }
    return isSend;
}
