I'm looking for some code in VB.NET on how to read the EPC, TID and User memory of a RFID tag using the WAP running on Windows CE and returning the values in a textbox.
Any help would be useful as I'm new to RFID, handheld computers and VB.NET.
Found the problem this morning: the 250ms delay (using system.threading.thread.sleep(250)) is not long enough! Since my reader was not connected, all commands sent to the reader were making the app crash.
I used 500ms instead and everything works perfectly!
Yes, it was that simple! But quite stupid that CAEN are not talking about this delay anywhere, and that in many demo applications 250ms is fine...
Just to follow up, I've been able to read the CAI and User memory of RFID tags...
I'm still unable to convert the hexadecimal string of the user memory to characters... If anyone has a piece of info, feel free to add it here!
