Why the card in SL3 returns nothing on the reader mfrc522?
I send the command with this format ( iso 14443-4 (after sending rats)) PCB + CID + INF + CRC => (INF contain command from datasheet mifare Plus) If I trying authenticate in valid block, then nothing recive. I'm recive valid information of error when block or length is invalid. But nothing recive if the command are valid. Please, help!
First send invalid command, second send valid command:
PCB CID 4-byte command CRC
Send: 0x0A, 0x02, 0x70, 0x40, 0x00, 0x00, crc1 ,crc2;
Recive: 0x0A, 0x02, 0x09, 0x1F, 0x78;
Error code 0x09 => Block Number is not valid
Send : 0x0A, 0x02, 0x70, 0x00, 0x40, 0x00, crc1 ,crc2;
Recive: nothing
mfrc522 doesn't support the iso standard: 14443-4.
The: PN532 does I believe.
