我已经配置了 GPS 设备并在 C# 中创建了一个侦听器应用程序。我只收到来自设备的 IMEI 号码，而不是任何 GPS NMEA 数据。但是为了检查我何时在 GPS Gate 服务器中检查相同的内容，它会在地图中显示移动。有什么建议么！！！
以下是如何执行数据处理
TcpClient client = (TcpClient)tcpClient;
Byte[] bytes = new Byte[10000];
String data = null;
int i;
NetworkStream stream = client.GetStream();
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
}
Console.WriteLine(data);
当它进入while循环时，它只是等待和睡眠:(
我认为该设备具有类似的模式
Step1：收到IMEI号码后
Step2：重播“01”状态到同一个新作品
代码：
TcpClient newClient = (TcpClient)client;
NetworkStream ns = newClient.GetStream()
byte[] bytes = new byte[1024];
bytes = Encoding.ASCII.GetBytes("X");
Console.WriteLine("X");
ns.Write(bytes, 0, bytes.Length);
参考。FMXXXX 协议 V2.7
我认为你需要做这样的事情（简单的解决方案）。如果你能让它工作，也许你应该检查一些异步套接字/tcp 连接
TcpClient client = (TcpClient)tcpClient;
Byte[] bytes = new Byte[10000];
String data = null;
int i;
NetworkStream stream = client.GetStream();
// Will get data as long as data is available after 1st read
do
{
i = stream.Read(bytes, 0, bytes.Length)
data = String.Concat(data, System.Text.Encoding.ASCII.GetString(bytes, 0, i));
}
while(stream.DataAvailable);
// Write the data to console (first time it should be IMEI
Console.WriteLine(data);
// Write 1 to the stream, note it must probably be byte value 1 -> 0x01
// Flush output stream after writing to prevent buffering
data = "";
// Now try if more data comes in after IMEI and 0x01 reply
do
{
i = stream.Read(bytes, 0, bytes.Length)
data = String.Concat(data, System.Text.Encoding.ASCII.GetString(bytes, 0, i));
}
while(stream.DataAvailable);
// Write date to console - move inside the while loop if data keeps coming in
Console.WriteLine(data);
您必须首先使用以下步骤配置您的跟踪器，如图所示：
要启动配置过程，配置服务器会发送包含服务器主机（IP 地址）的二进制启动 SMS（“Push” SMS），并且 tcp 端口设备应连接并等待 TCP 连接。
收到“推送”短信后，设备尝试使用 GPRS 与配置服务器建立 TCP 连接。如果 TCP 连接尝试成功，服务器通过已建立的连接向设备发送配置数据，设备确认接收配置并自行配置。
如果设备在 TcpWaitTimeout 时间内没有连接到服务器，则服务器停止等待 TCP 连接，使用二进制短信发送配置数据，并等待来自设备的确认短信。如果确认短信没有在指定时间内到达，服务器会认为配置过程失败。
