Detailed Description

File Control TLV block parser for Type 4 Tag (T4T).

Enumeration Type Documentation

Possible types of File Control TLV for Type 4 Tag.

Enumerator
NDEF_FILE_CONTROL_TLV	Control information concerning the EF file with short NDEF message.
PROPRIETARY_FILE_CONTROL_TLV	Control information concerning the Proprietary file with proprietary data.
EXTENDED_NDEF_FILE_CONTROL_TLV	Control information concerning the EF file with long NDEF message.

ret_code_t nfc_t4t_file_control_tlv_parse	(	nfc_t4t_tlv_block_t *	p_file_control_tlv,
		uint8_t *	p_raw_data,
		uint16_t *	p_len
	)

Function for parsing raw data of File Control TLV, read from a Type 4 Tag.

This function parses raw data of File Control TLV and stores the results in its descriptor.

Parameters

[in,out]	p_file_control_tlv	Pointer to the File Control TLV that will be filled with parsed data.
[in]	p_raw_data	Pointer to the buffer with raw TLV data.
[in,out]	p_len	In: Buffer length with TLV blocks. Out: Total length of first identified TLV within the buffer.

Return values

NRF_SUCCESS	If operation was successful.
NRF_ERROR_INVALID_LENGTH	If provided buffer length is too small for TLV block.
NRF_ERROR_INVALID_DATA	If any TLV block field contains invalid data.

void nfc_t4t_file_control_tlv_printout	(	uint8_t	num,
		nfc_t4t_tlv_block_t *	p_t4t_tlv_block
	)

Function for printing TLV block descriptor.

This function prints TLV block descriptor.

Parameters

[in]	num	TLV block number.
[in]	p_t4t_tlv_block	Pointer to the TLV block descriptor.
