14443 TypeB card reader using PN532

Hi, I have a question regarding PN532.

We are designing an NFC typeB card reader using PN532.

Following is the log of the communication between PC and the card reader “IFD” equipped with PN532.

 

PC -> IFD : INITIATOR : LIST PASSIVE TARGETS
00 00 FF 09 F7 D4 4A 01 01 00 FF FF 00 00 E2 00

IFD -> PC : ?
           00 00 FF 00 00 D5 00

 

We think that the response from IFD should be ACK,

00 00 FF 00 FF 00

 

Actually in case of the card reader equipped with PN533, the response was ACK.

 

Does anyone know the reason why the response is not ACK?

 

I’d appreciate any rresponse.

 

Regards,
