SerialPortを使用してATCOMMANDでc#を介して+ CDSを取得すると、この+ CDSが切り捨てられるたびに、問題が発生します。例:
+ CDS:25 0002970C91555868047414212181414094882121814140948830
なぜ私はこの問題を抱えているのですか、なぜいつでもうまくいくのですか?
私はSerialPortを始めています:
public PortCOM(string porta)
: base(porta, 115200, Parity.None, 8, StopBits.One)
{
this.StatusPort = StatusPorta.Ready;
this.DiscardNull = true;
this.ReadTimeout = 21000;
this.RtsEnable = true;
this.DtrEnable = true;
this.ReceivedBytesThreshold = 9;
this.NewLine = "\r\n";
this.ReadBufferSize = 1024;
}
public static void TestPort()
{
var p = new PortCom("COM12");
if (!p.IsOpen)
p.Open();
p.StatusPort = StatusPorta.Ready;
p.DataReceived += new SerialDataReceivedEventHandler(p_DataReceivedSample);
p.PinChanged += new SerialPinChangedEventHandler(p_PinChanged);
p.ErrorReceived += new SerialErrorReceivedEventHandler(p_ErrorReceived);
p.Disposed += new EventHandler((obj, porta) =>
{
Console.WriteLine(((PortaCOM)obj).ToString());
});
if (Console.ReadKey().Key == ConsoleKey.B)
{
p.Close();
p.Dispose();
}
}
static void p_DataReceivedSample(object sender, SerialDataReceivedEventArgs e)
{
var p = (PortaCOM)sender;
try
{
Console.WriteLine(p.ReadExisting());
var sb = new StringBuilder();
sb.Append(p.ReadExisting());
int y = sb.ToString().IndexOf("\r\n");
var stop = Stopwatch.StartNew();
stop.Start();
while (y == -1)
{
sb.Append(p.ReadExisting());
y = sb.ToString().IndexOf("\r\n");
if (stop.Elapsed.TotalSeconds > 10)
break;
}
stop.Stop();
var _retorno = sb.ToString();
var cmt = regCMT.Match(_retorno);
var succ = regSucess.Match(_retorno);
var report = regStatusReport.Match(_retorno);
var erro = regError.Match(_retorno);
#region Resposta
if (cmt.Success)
{
var smss = new SMS();
var source = cmt.Groups[3].Value;
SMS.Fetch(smss, ref source);
var resposta = new Resposta()
{
Mensagem = smss.Message,
Data = smss.ServiceCenterTimeStamp,
Sender = smss.PhoneNumber,
Operadora = p.OperadoraName.NomeOperadora.ToString()
};
GravaResposta().ToAsync(Scheduler.TaskPool).Invoke(p, cmt.Groups[3].Value);
p.IsError = false;
}
#endregion
#region StatusReport
if (report.Success)
{
RecebeReport(p, report.Groups[2].Value.Trim());
p.IsError = false;
}
#endregion
}
catch (Exception err)
{
Console.WriteLine(err.Message);
}
}
本当に助けが必要です、助けてくれてうれしいです!
