Force Re-synchronization
"Force Re-Synchronization" forces BTTracer to re-synchronize at the
beginning of each "Page Sync & Record," "Passive Sync & Record," or
"Sync & Record" operation. By default, "Force Re-Synchronization" is
disabled (i.e., unchecked).
Unchecking the "Force Re-Synchronization" checkbox tells BTTracer to
use its existing data on Bluetooth™ devices, thereby bypassing the
synchronization process and saving a few seconds from the beginning of the
trace. If you know that BTTracer’s data is correct, you can uncheck this
checkbox and cause BTTracer to try to use the existing data. If the data is
incomplete or incorrect, however, BTTracer will automatically perform a
refresh.
To examine BTTracer’s Bluetooth™ data, open "BT Neighborhood" under
the View menu.
Follow Master/Slave Switch
If enabled, this option allows BTTracer to follow a role switch between a
Master and Slave. This capability allows BTTracer to keep track of changes
in a device’s role when it changes from one role to another.
BTTracer is able to follow a role change by listening to the Slave device’s
Bluetooth clock and hop frequency as soon as it becomes a Master.
Match Clock Rate
Match Clock Rate is a useful option if the Master device’s clock is
inaccurate. Match Clock Rate causes BTTracer to do a General Inquiry to
determine the Page Target's clock rate prior to synchronizing to the piconet.
If unchecked, BTTracer will begin piconet synchronization without first
doing a General Inquiry.
This option only works with Page Sync and Record mode.
Show Paging Traffic
Show Paging Traffic causes BTTracer to capture paging traffic between the
Master and Page Target devices. This option is used only with Page Sync
and Record Mode.
Piconet Addresses (MSB -> LSB)
• Master Addr - Piconet Master Address for device under
observation. Used for all Piconet recording modes.
• Page Target - User selectable address for the BTTracer
Analyzer. Used for Passive Sync & Record and Page Sync &
