我想用c#通过gsm调制解调器接收消息。我已经写了一个代码,但在控制台上,每当收到消息时,我就会得到连续的错误流。请帮我接收一条信息。这是我的代码。
static void Main(string[] args)
{
SerialPort serialport = new SerialPort();
int mSpeed = 1;
serialport.PortName = "COM16";
serialport.BaudRate = 9600;
serialport.Parity = Parity.None;
serialport.DataBits = 8;
serialport.StopBits = StopBits.One;
serialport.Handshake = Handshake.XOnXOff;
serialport.DtrEnable = true;
serialport.RtsEnable = true;
serialport.NewLine = Environment.NewLine;
serialport.DataReceived += newSerialDataReceivedEventHandler(DataReceivedHandler);
serialport.Open();
Console.ReadKey();
}
private static void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
SerialPort sp = (SerialPort)sender;
sp.WriteLine("AT+CMTI" + Environment.NewLine);
Console.WriteLine(sp.ReadLine());
}
}
您的serialport.Open()
使用这些代码后。serialport.Write("AT+CMGF=1'r"); // Instruct the GSM modem to operate in SMS text mode
serialport.Write("AT+CNMI=1,2,0,0,0'r"); // Receive notification of incoming messages
试试这个. .你的DataReceivedHandler
。SerialPort sp = (SerialPort)sender;
string input = sp.ReadExisting();
Console.WriteLine(input);
