The Event triggering and filtering options allow you to set event conditions

Additional Timeslot Filtering
By default, Merlin records frequency hop and timestamp information for all
time slots in the Piconet under analysis, regardless of whether the time slot
contained a Bluetooth packet. This means that in instances where there is
little piconet traffic, Merlin will display row after row of empty packets --
each representing an empty time slot. Through the use of timeslot filtering,
these empty packets can be filtered out. Filtering out this information has
the benefit of freeing memory so that more traffic can be recorded.
Filter Empty Slots
If "Filter Empty Slots" is checked, Merlin will exclude all empty time slots
from a recording except for those that lie immediately in front of Bluetooth
communications packets. These remaining empty packets are preserved to
give timestamp and frequency hop reference data to the packets that follow.
