getObservedTagIDs

With this command, the selected read point takes an inventory and returns all identified
transponders in the reply frame.
In contrast to the "readTagIDs" command, the smoothing algorithm of the selected read point
is also affected here. The read point must therefore take enough inventories until a
transponder adopts the "Observed" status. This can be achieved by selecting the suitable
parameter values or by triggering/starting the read point in good time before the command.
If no transponder was identified with the "Observed" status, a positive reply without
transponder data is returned.
