nfc_t2t_internal_set()

int nfc_t2t_internal_set	(	const uint8_t *	data,
		size_t	data_length
	)

#include <nfc/include/nfc_t2t_lib.h>

Register the sequence of internal bytes.

This refers to the first 10 bytes of the tag memory. The library will set a sensible default for these bytes. The application can use this function to override the default.

Passing a NULL pointer reverts back to the default sequence. The data will be copied by NFC T2T Library, so the memory does not have to remain valid after the function returns.

Note

When modifying the internal bytes, remember that they must be consistent with the NFC hardware register settings.

Parameters

data	Pointer to the memory area containing the data.
data_length	Size of the data in bytes.

Return values

0	Success.
-NRF_EINVAL	Invalid argument (e.g. wrong data length, NULL pointer).
