PN532 TransportData Questions

[kimhyungjun]

I know that PN532 is a transferable byte 262byte, but 64byte is sent when it is sent in P2P Initiator mode. How do I send more than 64 bytes?

Perhaps it is because the value of LRi in ATR_REQ is 00 and only 64byte data is checked. How can I change this value?

Hi @kimhyungjun ,

The command of InDataExchange can be used for that purpose, and there is an example in Fig 103., please refer to https://www.nxp.com/docs/en/user-guide/141520.pdf for more details.

Hope that helps,

Have a great day,
Kan
