6.1.1. [0x01] Inventory
This command reads the UID of all Transponders inside the antenna field. If the Reader has detected
a new Transponder, the Transponder will be automatically set to the quiet state by the Reader. In this
state the Transponder does not send back a response for the next inventory command.
The Transponder sends back a response every time:
•
if the Transponder has left the antenna and reentered the antenna field or
•
if a command was send to the Reader or
•
if the ONT bit in the ONT register of the
3.6. CFG5: Anticollision
configuration block is not set.
