5.4.13 Inventory-Cyclic (50-02)
This function can be used to start and stop a cyclic inventory. With a cyclic inventory the reader does inventories
autonomous in a specified cycle. The timeout between such cycles can be found in the manual of the reader.
This function can be activated and deactivated:
enum INVENTORY_MODE (unsigned char)
INVENTORY_OFF 0x00
INVENTORY_ON 0x01
After an activation packet was sent from the PC to the reader, the reader sends an answer with the status of the
operation. Afterwards interrupt messages are sent to the PC in a defined cycle.
Parameters: InventoryMode mode
Return Values: RFE_RET_VALUE status
Status Values: RFE_SUCCESS, RFE_ERR_ON_EXEC_OP, RFE_ERR_WRONG_PARAM_COUNT,
RFE_ERR_WRONG_PARAM
