I'm trying to use the PN532 by Elechouse V3 connected through i2c to the raspberry-pi to read debit and credit card and I manage to read the type-A card successfully. I can't read the type-b cards though.

These are the step I'm following according to the manual https://www.nxp.com/docs/en/user-guide/141520.pdf:

Setting SAM configuration to normal mode sending bytes [0xD4, 0x14, 0x01, 0x01, 0x00] (not sure this is required though)
Sending InListPassiveTarget with bytes [0xD4, 0x4A, 0x01, 0x03, 0x01]

I was expecting to be able to read the type-B cards at this point but nothing happens when I try to put a card close to the reader.

I've also tried changing the RF configuration settings sending the bytes [0xD4, 0x32, 0x0C, 0xFF, 0x17, 0x85] before the InListPassiveTarget and also tried using the InAutoPoll method with all the possible values but still no luck.

Any idea or suggestion would be really appreciated

Have you tried setting the last byte (AFI) of InListPassiveTarget to zero (`D4 4A 01 03 00`)? – Michael Roland Dec 19 '17 at 11:15
@MichaelRoland I tried that already and it doesn't work. Thanks for the comment though – DavideGalifi Dec 19 '17 at 12:35
did you ever find a solution for this, i.e. RF parameters that work? I am stuck with the same problem – ndbd Dec 02 '20 at 12:26
