Hi to all,
Anyone here have done a successful RFID passive tag read? Bought some passive tags, a rfid reader and antenna but nothing seems to work.
So basically, a RS-232 cable is attached to a TTL board, which is then attached to the reader. The reader is attached to the antenna.
Installed COM port sniffer (using Windows) to detect traffic from COM to Reader. I can see traffic from COM port to reader but not the other direction.
The reader seems to respond to baud rate 9600 and below.
First question. Anyone here knows the sequence of data to transmit? Can't find any rfid data protocol.
Second question. Any recommended SDK library?
