接收短信收件箱数据 [英] Receive SMS inbox data

问题描述

大家好，

我目前正在尝试使用C#访问GSM调制解调器的SMS收件箱.我已经成功发送了短信，并且能够在超级终端中使用AT COMMANDS检索SMS数据，但是我无法使超级终端中显示的数据能够在C#应用程序中显示.

我已经设置了一个数据接收事件处理程序，该事件处理程序在响应AT命令并以对命令的响应方式(例如OK，ERROR，RING)从设备获取数据时似乎正在工作，但是我无法获取从gsm调制解调器检索SMS消息的命令返回的数据.

这是可在超级终端中使用的代码

//AT + CMGL =""REC UNREAD""

//+ CMGL:304，"REC UNREAD"，"+ 61403075676"

//TEST 7

//确定

//AT + CMGR = 304

//+ CMGR:"REC READ"，"+ 61403075676"，"2006/1/17,11:56:38"；

//TEST 7

//确定

在C#应用中，以下代码无错误执行

port.WriteLine( " AT + CMGF = 1 \ r" );

port.WriteLine( " AT + CMGL = \" REC UNREAD \" ) ;

但是GSM调制解调器没有响应，我如何才能在C#应用程序中获得超级终端中回复的行.

非常感谢您的帮助

解决方案

抽奖太快了，我一发布便发现了自己的错误.

需要返回卡拉奇:port.WriteLine("AT + CMGL = \" REC UNREAD \" )；

愚弄我.

Hi all,

Im currently trying to access the SMS inbox of a GSM modem in C#. I have successfully sent sms messages and have been able to use the AT COMMANDS in hyperterminal to retreive SMS data, but I have not been able to get the data shown in hyperterminal to be shown in C# app.

I have set up a datareceived event handler which appears to be working as I get my AT commands echoed by it and I get data from the device in the way of responses to my command such as OK, ERROR, RING, but I am not able to get the data returned form the command to retrieve SMS messages from the gsm modem.

This is the code that works in Hyperterminal

//AT+CMGL="REC UNREAD"

//+CMGL: 304, "REC UNREAD", "[phone]"

//TEST 7

//OK

//AT+CMGR=304

//+CMGR: "REC READ", "[phone]", "2006/1/17,11:56:38"

//TEST 7

//OK

In C# app the following code executes without error

port.WriteLine("AT+CMGF=1\r");

port.WriteLine("AT+CMGL=\"REC UNREAD\"");

But there is no response form the GSM Modem, how do I get the lines that where replied in hyperterminal to be abtainable in C# app.

 

Many thanks for your assistance

解决方案

Too quick of the draw, I found my error as soon as I posted.

Carraige return is required: port.WriteLine("AT+CMGL=\"REC UNREAD\"\r");

Foolish me.
