Grove NFC - Peer to Peer using UART

Dear support team,

I have successfully used your Grove NFC ver 1.1 to read and write to tags. However I couldn’t find anything for using it for P2P. When I try to use the write function used for writing to tags but passing the message size it says that the function does not exist.

Is there any documentation available?

Thank you,

Hi there~

Please check below link and see if it works. thanks.

Thank you.

I tried using the libraries and the examples to do a P2P communication but it seems like all examples require the following libraries:

#include “SPI.h”

#include “PN532_SPI.h”

#include “llcp.h”

#include “snep.h”

PN532_SPI pn532spi(SPI, 10);

SNEP nfc(pn532spi);

However the NFC is connected using UART and there is no P2P example using UART or HSU.

Can you please provide an example Peer to Peer using PN532_HSU library?

Also in the examples it does mention that:

P2P requires SPI and has only been tested with the Seeed Studio shield. Peer to Peer was tested between Arduino and Android or BlackBerry

Thank you

Dear Support team,

Is there any way to get Peer to Peer Communication to work using HSU and UART with the PN532_HSU library?

Thank you!
