You see the Event Groups window:
The Event triggering and filtering options allow you to set event conditions
for errors and/or a variety of packet characteristics.
Clicking a check box causes further options to display in the right side of the
window.
Additional Timeslot Filtering
By default, Merlin Mobile 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 Mobile 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 Mobile 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.
