Detailed Description

Function Documentation

WriteEmulationNdefM()

UFR_STATUS DL_API WriteEmulationNdefM	(	UFR_HANDLE	hndUFR,
		uint8_t	tnf,
		IN uint8_t *	type_record,
		uint8_t	type_length,
		IN uint8_t *	id,
		uint8_t	id_length,
		IN uint8_t *	payload,
		uint8_t	payload_length )

Multi reader support. Function stores a message record for NTAG emulation mode into the reader. Parameters of the function are: TNF, type of record, ID, payload. Maximum total size for emulated NDEF message is 144 bytes.

Parameters

hndUFR	handle of the uFR device
tnf	TNF of the record
type_record	pointer to the array containing record type
type_length	length of the record type
id	pointer to the array containing record ID
id_length	length of the record ID
payload	pointer to the array containing record payload
payload_length	length of the record payload

Returns

Operation status

TagEmulationStartM()

UFR_STATUS DL_API TagEmulationStartM

(

UFR_HANDLE

hndUFR

)

Multi reader support. Put the reader permanently in a NDEF tag emulation mode. Only way for a reader to exit from this mode is to receive the TAG_EMULATION_STOP command (issued by calling TagEmulationStop() function). In this mode, the reader can only answer to the commands issued by a following library functions: TagEmulationStart(), WriteEmulationNdef(), TagEmulationStop(), GetReaderSerialNumber(), GetReaderSerialDescription(), GetReaderHardwareVersion(), GetReaderFirmwareVersion(), GetBuildNumber() Calls to the other functions in this mode returns following error code: FORBIDDEN_IN_TAG_EMULATION_MODE = 0x90

Parameters

hndUFR

handle of the uFR device

Returns

Operation status

TagEmulationStopM()

UFR_STATUS DL_API TagEmulationStopM

(

UFR_HANDLE

hndUFR

)

Multi reader support. Allows the reader permanent exit from a NDEF tag emulation mode.

Parameters

hndUFR

handle of the uFR device

Returns

Operation status

WriteEmulationNdefRamM()

UFR_STATUS DL_API WriteEmulationNdefRamM	(	UFR_HANDLE	hndUFR,
		uint8_t	tnf,
		uint8_t *	type_record,
		uint8_t	type_length,
		uint8_t *	id,
		uint8_t	id_length,
		uint8_t *	payload,
		uint32_t	payload_length )

Multi reader support. From library version 5.0.31, and firmware version 5.0.33 Function stores a message record for NTAG emulation mode into the reader in the RAM. Parameters of the function are: TNF, type of record, ID, payload. Maximum total size for emulated NDEF message is 1008 bytes. Unlike the function WriteEmulationNdef, the data is not written to the EEPROM of the reader, so they cannot be loaded after the reader is reset. This function must be called after reader reset to use the NTAG emulation.

Parameters

hndUFR	handle of the uFR device
tnf	TNF of the record
type_record	pointer to the array containing record type
type_length	length of the record type
id	pointer to the array containing record ID
id_length	length of the record ID
payload	pointer to the array containing record payload
payload_length	length of the record payload

Returns

Operation status
