I'm developing a simple application for MC319Z RFID reader using Visual Studio 2008 and EMDK v2.9.
I refer the EMDK Programmer's Guide in order to work with RFID.
The following code is used, just three strings:
string hostname = "127.0.0.1";
RFIDReader rfid3 = new RFIDReader(hostname, 0, 0);
I know the RFIDReader class uses the LLRP service running on the device.
It's configured by default:
Unfortunately I get an exception after the "Connect" method call:
Exception occured: Symbol.RFID3.OperationFailureException: Connect
at Symbol.RFID3.ProcessErrorCode.ThrowException(IntPtr readerHandle, String sMessage, RFIDResults results, Boolean getLastError)
Status: Unable to open connection to reader
The in-built demo app works stable.
It seems the LLRP service is busy.
I stopped and started RFID (the icon on the home screen indicates the "running" state), closed all the 3d party apps running in the background but I still can't access the reader.
How can I get rid of this problem?
Could you provide me some way to debug this issue, please?
