我在使用摩托罗拉的条码扫描仪 MT2070 时遇到问题。我使用 EMDK 2.6 for .NET(更新 2)从扫描的条形码创建字符串,然后将它们传输到主机 pc。但是传送失败了。
MT2070 运行 Windows CE5.0 并通过蓝牙连接到底座 STB2078。但是每次我得到“发送失败”并且结果代码是“E_INCORRECT_MODE”。
问题是不明白它们对“INCORRECT_MODE”的含义我将它设置为 DECODE 和 RawData 是什么意思与源?
ScannerServicesClient scannerServices;
scannerServices = new ScannerServicesClient();
SCANNERSVC_MODE mode;
if(scannerServices.Connect(true))
{
Logger("start service with decode rights"); // primitiv method to see what happen
scannerServices.GetMode(out mode);
if (mode != SCANNERSVC_MODE.SVC_MODE_DECODE)
{
mode = SCANNERSVC_MODE.SVC_MODE_DECODE;
if (scannerServices.SetMode(mode) != RESULTCODE.E_OK)
{
Logger("cant set mode: " + mode.ToString());
}
}
// wanna know which connection is use
string connection = "";
switch (scannerServices.HostParameters.CurrentConnection)
{
case SCANNERSVC_DATA_CONNECTION.NO_CONNECTION:
connection = "Not connected";
break;
case SCANNERSVC_DATA_CONNECTION.BLUETOOTH:
connection = scannerServices.HostParameters.BluetoothConnection.ToString();
break;
case SCANNERSVC_DATA_CONNECTION.RS232:
connection = scannerServices.HostParameters.RS232Connection.ToString();
break;
case SCANNERSVC_DATA_CONNECTION.USB_CABLE:
connection = scannerServices.HostParameters.USBConnection.ToString();
break;
}
Logger(connection);
ScannerHostParameters scnHost = new ScannerHostParameters(scannerServices);
//example hello
string input = "hello"; //what should send
byte[] output = new byte[input.Length]; //field with converted data
byte source = 0; //<-- what mean source? i sum all byte-value but this cant be correct
for (int i = 0; i < input.Length; ++i)
{
output[i] = Convert.ToByte(input[i]);
source += output[i];
}
RawData rawData = new RawData(output, input.Length, source);
//RawParameters rawParam = new RawParameters();
//rawParam.BaudRate = RawParameters.RawBaudRates.RAWSERIAL_9600;
//rawParam.Type = RawParameters.RawHostType.Auto;
RESULTCODE result = scannerServices.SendRawData(rawData, 2000);
if(result == RESULTCODE.E_OK)
{
Logger("successful send");
}
else
{
Logger("Send failed: " + result.ToString());
}
Logger("ScannerService kill");
scannerServices.Disconnect();
}
Logger("\n");
scannerServices.Dispose();
scannerServices = null;
谢谢你的帮助!(对不起我的英语)
