Hi, I’m new to Arduino and NFC. I’m having fun trying to read a 14443-3A NFC card on the NFC shield. It reads the ID code of the card easy. However I can’t read data or authenticate. I’ve changed the PN532 lib from seeedstudio.com/wiki/index.p … NFC_Shield so that I can see the data going out and in.
AUTH Packet To PN532 looks like : 40 1 60 0 0 0 0 0 0 0 E2 36 CC 86
Sending: 0x0 0x0 0xFF 0xF 0xF1 0xD4 0x40 0x1 0x60 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0xE2 0x36 0xCC 0x86 0x21 0x0
Reading: 0x0 0x0 0xFF 0x0 0xFF 0x0
Reading: 0x0 0x0 0xFF 0x3 0xFD 0xD5 0x41 0x14
I’m needing some pointers, I’ve been googling trying to find a better NFC lib for Arduino or any sort of doc which helps me figure out why the PN532 or the NFC Card are replying with a 0x41 0x14. I found a few bits and pieces on MiFARE 14443-1 but nothing which is helping. Looking at the PN532 lib I should have got a 0x41 0x00?
