Hi All,
I have wrote a simple program using RS232 protocol. However, I have the following problem in hand.
I used the software to receive data from a RFID reader (you may simply treat it like a barcode scanner) through RS232 communication. The software does receive strings from the reader every time an event is triggered (i.e. a tag is read by the reader). I'm sure the Expecting reading data should look similar to this:
{002123579ABCDE F000098EB18, .........
However, the Actual reading data is rather not understandable. The following is an example:
'y'y'y'y'y
I have a feeling that it can be a simple encoding/decoding problem and checksum. Any comments will be greatly appreciated.
Thanks in advanced
