This command group implements the low-level ISO 14443-4 commands according to the ISO 14443-4 standard.
While the ISO 14443-3 Type A and Type B standards define request and selection mechanisms for PICCs, the ISO 14443-4 standard defines a protocol capable of transferring so-called application layer data units (APDUs) with previously selected labels.
Please refer to the iso14a.h or to the iso14b.h for more information on how to put ISO 14443-3 (Type A) or ISO 14443-3 (Type B) PICCs into the active state.
APDUs can be transmitted and received to/from a PICC using the brp_Iso14L4_ExchangeAPDU() command, provided the PICC is in active state. Before calling the brp_Iso14L4_ExchangeAPDU() command, the target PICC has to be selected using the brp_Iso14L4_SetupAPDU() command. The brp_Iso14L4_SetupAPDU() command furthermore enables to change the communication parameters of the reader to match the capabilities of the target PICC. These communication parameters apply to all following calls of the brp_Iso14L4_ExchangeAPDU() and brp_Iso14L4_Deselect() commands, until the brp_Iso14L4_SetupAPDU() command is called with different parameters. The brp_Iso14L4_Deselect() command is used to switch a PICC to halt state after exchange with this PICC has been completed.
PICCs can also be put to the halt state using the brp_Iso14a_Halt() command or the brp_Iso14b_Halt() command. However these commands only work for PICCs which are not in ISO 14443-4 mode (when considering Type A PICCs) or for PICCs in ready state, not in active state (when considering Type B PICCs). In other situations, the brp_Iso14L4_Deselect() command should be used.
