Filter Empty Slots
If "Filter Empty Slots" is checked, BTTracer 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.
Filter Slots on Packet Filter
If filters are used to exclude FHS, DM1 or other packets, BTTracer will
exclude these packets from a trace and mark their locations with empty
packets. The result can be rows and rows of empty packets. The option
"Filter Empty Slots" will not exclude these empty slots because they lie
immediately in front of Bluetooth communications packets - even though
those packets were not recorded. To eliminate these empty packets, select
"Filter Slots on Packet Filter."
Packet Headers
Clicking "Packet Headers" opens three sets of check boxes and menus on
the right that represent fields within packet headers: Packet Type, Active
Member Address, Flow Control, Acknowledgment, and Sequence Number.
• Select Packet Headers under Event Groups.
You see the Packet Headers window:
