nfc_t4t_response_pdu_send()

int nfc_t4t_response_pdu_send	(	const uint8_t *	pdu,
		size_t	pdu_length
	)

#include <nfc/include/nfc_t4t_lib.h>

Send a raw response PDU after getting a Request PDU callback.

When the library works in raw ISO-DEP mode it will signal request PDUs through the callback. The application then has to answer with a response PDU. It will use this function to send back the response PDU. This function can not be used in T4T NDEF (RW / STATIC) emulation modes.

The lower ISODEP layer will handle the defragmentation of a long response PDU into smalleR pieces that the PCD can understand.

Parameters

pdu	Const PDU pointer.
pdu_length	Length of PDU.

Return values

0	Success.
-NRF_EINVAL	Invalid argument (for example, wrong data length, NULL pointer).
-NRF_EOPNOTSUPP	Emulation is in running state.
