Hello Everybody, i bought a PN532 RFID for read an write rfid tags with ISO 14443 Type B protocol, and when i wrote the function: InDataExchange the response is an array of pure 80 80 80  80  numbers, the packet buffer settings are the next:

pn532_packetbuffer[0] =4A; //
pn532_packetbuffer[1] = 1
pn532_packetbuffer[2] = 0x94;
pn532_packetbuffer[3] = 0xA4; 
pn532_packetbuffer[4] = 0x00;
pn532_packetbuffer[5] = 0x00;
pn532_packetbuffer[6] = 0x02;
pn532_packetbuffer[7] = 0x3F;
pn532_packetbuffer[8] = 0x00;

this numbers are extracted for the Application Note in the Table 4. The PN532 as a ISO/IEC 1443-4 reader. Type B card activation( I upload the pdf here), i hope if somebody can help me.

Hello,

Could you please provide us with more information?

Which MCU are you working with as host MCU? Are you working with the Software Development Kit? available in the Software & Tools section of PN532: NFC integrated solution|NXP 

Is there a way to get the log files in the IDE and/or logic analyzer frames? i.e. command sent, answer received.

Thank you.

Regards,

Ivan.

Hello,

In this case. Answering to your question, there is a Software Development Kit which you can take as reference for your project.

You will find it in the software & tools section:

NFC integrated solution|NXP 

Have a nice day!

Ivan.
