Function Documentation

ret_code_t nfc_t4t_cc_read

(

nfc_t4t_capability_container_t *const

p_cc_file

)

Function for performing Capability Container Read Procedure.

This function performs Capability Container Read Procedure according to "Type 4 Tag Operation" (Version 3.0 published on 2014-07-30) chapter 5.5.4.

Parameters

[out]

p_cc_file

Pointer to the Capability Container descriptor.

Return values

NRF_SUCCESS	If Capability Container file was successfully read.
NRF_ERROR_NO_MEM	If APDU buffer or CC file storage buffer is too small.
NRF_ERROR_NOT_SUPPORTED	If the requested response length in C-APDU is too big.
NRF_ERROR_NULL	If R-APDU did not return any data bytes.
NRF_ERROR_INVALID_DATA	If CCLEN field is not coherent with R-APDU data length.
Other	Other error codes may be returned depending on functions adafruit_pn532_in_data_exchange , nfc_t4t_cc_file_parse , and on APDU reader/writer module functions.

ret_code_t nfc_t4t_cc_select

(

void

)

Function for performing Capability Container Select Procedure.

This function performs Capability Container Select Procedure according to "Type 4 Tag Operation" (Version 3.0 published on 2014-07-30) chapter 5.5.3.

Return values

NRF_SUCCESS	If the Capability Container file was successfully selected.
NRF_ERROR_NOT_FOUND	If the Capability Container file was not found.
NRF_ERROR_NO_MEM	If the APDU buffer is too small.
Other	Other error codes might be returned depending on function adafruit_pn532_in_data_exchange and on APDU reader/writer module functions.

ret_code_t nfc_t4t_file_select

(

uint16_t

file_id

)

Function for performing NDEF Select Procedure.

This function performs NDEF Select Procedure according to "Type 4 Tag Operation" (Version 3.0 published on 2014-07-30) chapter 5.5.5.

Parameters

[in]

file_id

File Identifier to choose the correct file.

Return values

NRF_SUCCESS	If NDEF file was successfully selected.
NRF_ERROR_NOT_FOUND	If NDEF file was not found.
NRF_ERROR_NO_MEM	If APDU buffer is too small.
Other	Other error codes may be returned depending on function adafruit_pn532_in_data_exchange and on APDU reader/writer module functions.

ret_code_t nfc_t4t_ndef_read	(	nfc_t4t_capability_container_t *const	p_cc_file ,
		uint8_t *	p_ndef_file_buff ,
		uint8_t	ndef_file_buff_len
	)

Function for performing NDEF Read Procedure.

This function performs NDEF Read Procedure according to "Type 4 Tag Operation" (Version 3.0 published on 2014-07-30) chapter 5.5.6.

Parameters

[in,out]	p_cc_file	Pointer to the Capability Container descriptor.
[out]	p_ndef_file_buff	Pointer to the buffer where the NDEF file will be stored.
[in]	ndef_file_buff_len	Length of the provided NDEF file buffer.

Return values

NRF_SUCCESS	If NDEF file was successfully read.
NRF_ERROR_NO_MEM	If APDU buffer or NDEF file buffer is too small.
NRF_ERROR_NOT_SUPPORTED	If requested response length in C-APDU is too big.
NRF_ERROR_NULL	If R-APDU did not return any data bytes.
NRF_ERROR_INVALID_DATA	If NLEN field is not coherent with R-APDU data length.
Other	Other error codes may be returned depending on function adafruit_pn532_in_data_exchange , nfc_t4t_file_content_set , and on APDU reader/writer module functions.

ret_code_t nfc_t4t_ndef_tag_app_select

(

void

)

Function for performing NDEF Tag Application Select Procedure.

This function performs NDEF Tag Application Select Procedure according to "Type 4 Tag Operation" (Version 3.0 published on 2014-07-30) chapter 5.5.2.

Return values

NRF_SUCCESS	If NDEF Tag Application was successfully selected.
NRF_ERROR_NOT_FOUND	If NDEF Tag Application was not found.
NRF_ERROR_NO_MEM	If the APDU buffer is too small.
Other	Other error codes may be returned depending on function adafruit_pn532_in_data_exchange and on APDU reader/writer module functions.

ret_code_t nfc_t4t_ndef_update	(	nfc_t4t_capability_container_t *const	p_cc_file ,
		uint8_t *	p_ndef_file_buff ,
		uint8_t	ndef_file_buff_len
	)
