Function Documentation

◆ EraseData()

quint8 RLMXXXCRC::EraseData	(	const QByteArray &	AccessPwd,
		quint8	Bank,
		const QByteArray &	Ptr,
		quint8	Cnt,
		QByteArray &	Tid,
		quint8 &	ec
	)

Function to erase data from Tag memory.

Its called by application. This function must called with 4 byte access password, memory bank selector, start position within the bank, words to erase, and the Tag identifier (PC+EPC). If the Tag identifier is not given, the function erase the Tag first find in the field, and returns on success, this identifier. If the call failed an error code will be provided from module.

Parameters

[in]	AccessPwd	ByteArray of 4 byte with the Tag access password
[in]	Bank	Tag memory bank selector [1-3]
[in]	Ptr	ByteArray with EVB-8 encoded position
[in]	Cnt	Words to write (currently 1 only)
[in]	Tid	ByteArray with Tag identifier
[out]	ec	Error Code returned from the module if command failed

Returns: 1 on success, 0 if failed

◆ FastAuth()

quint8 RLMXXXCRC::FastAuth	(	const QList< QByteArray >	AccessPwdList,
		const QByteArray &	Tid,
		quint8 &	ec
	)

Function Fast authentication.

Its called by application. This function called with a list of max 4 access password, and the Tag identifier (PC+EPC). If the call failed an error code will be provided from module. The first password match the TAGs password let the function return success, otherwise fault, no password match.

Parameters

[in]	AccessPwdList	List with ByteArray of 4 byte Tag access passwords
[in]	Tid	ByteArray with Tag identifier
[out]	ec	Error Code returned from the module if command failed

Returns: 1 on success, 0 if failed

◆ KillTag()

quint8 RLMXXXCRC::KillTag	(	const QByteArray &	KillPwd,
		const QByteArray &	Tid,
		quint8 &	ec
	)

Function to kill a Tag.

Its called by application. This function must called with 4 byte kill password, and the Tag identifier (PC+EPC). If the call failed an error code will be provided from module.

Parameters

[in]	KillPwd	ByteArray of 4 byte with the Tag access password
[in]	Tid	ByteArray with Tag identifier
[out]	ec	Error Code returned from the module if command failed

Returns: 1 on success, 0 if failed

◆ LockMem()

quint8 RLMXXXCRC::LockMem	(	const QByteArray &	AccessPwd,
		const QByteArray &	LockData,
		const QByteArray &	Tid,
		quint8 &	ec
	)

Function to lock memory regions of a Tag.

Its called by application. This function must called with 4 byte access password, ByteArray with the mask and action field, and the Tag identifier (PC+EPC). If the call failed an error code will be returned.

Parameters

[in]	AccessPwd	ByteArray of 4 byte with the Tag access password
[in]	LockData	ByteArray with action/mask information ( 3 byte )
[in]	Tid	ByteArray with Tag identifier
[out]	ec	Error Code returned from the module if command failed

Returns: 1 on success, 0 if failed

◆ ReadBatch()

quint8 RLMXXXCRC::ReadBatch	(	const QByteArray &	AccessPwd,
		const quint8	Option,
		const quint8	initQ,
		const QList< QByteArray > &	BatchList
	)

Function to read multible areas of a TAG memory with a single command.

Its called by application. This function must called with 4 byte access password, bank selector option, initQ value and bank specific data. On success module send continously Tag information of the environment use the command RetriveBatchData() to retrive.

See also: RetriveBatchData()

Parameters

[in]	AccessPwd	ByteArray of 4 byte with the Tag access password
[in]	Option	Selector to read one or two memory banks
[in]	initQ	Anti collision parameter
[in]	BList	List of QByteArray with Bank,pointer and lenth of memory
[out]	Results	List of QByteArray with TID, and memory read from Tag

Returns: 1 on success, 0 if failed

◆ ReadData()

quint8 RLMXXXCRC::ReadData	(	const QByteArray &	AccessPwd,
		quint8	Bank,
		const QByteArray &	Ptr,
		quint8	Cnt,
		QByteArray &	Tid,
		QByteArray &	ReadData,
		quint8 &	ec
	)

Function to read the Tag memory.

Its called by application. This function must called with 4 byte access password, memory bank selector, start position within the bank, words to read, and the Tag identifier (PC+EPC). If the parameter Cnt is set to 0 the function returns all data available. If the Tag identifier is omitted (empty), on success the function return the Tag id which had been read.

If the call failed an error code will be provided from the module
