BTTracer Protocol Analyzer User’s Manual CATC SW Version 2.20
To the right of the Sync Method menu are two menus which let you select
or enter address for the devices in the piconet:
Master Address - Presents a drop-down list of Master devices found
previously. You can also enter address values in this box.
Page Target -- Presents a drop-down list of Page Target devices found
previously. You can also enter address values in this box.
Between the two text boxes is the following button:
- Swaps the Master and Page Target addresses.
When to Use the Different Piconet Recording Modes
Page Sync & Record is the preferred option and should be used whenever
possible. If Page Sync & Record can not be used, then Sync & Record
should be used. Passive Sync and Record should be used only if the first
two options can not be used.
Sync & Record
Sync and Record works just like "Page Sync and Record" except that
BTTracer takes its sync data directly from the Master instead of the Slave
devices. With Sync and Record, BTTracer conducts a General Inquiry to
get hop frequency and clock information from the Master. BTTracer then
waits to detect piconet traffic from the Master device’s piconet. When the
piconet is established, BTTracer is able to synchronize to the Master and
begin recording. In contrast to "Page Sync and Record", "Sync and Record"
can be run with or without an established piconet.
Note This mode can only be used to find master devices that support Inquiry Scan.
To perform a "Sync and Record", follow the steps below:
Step 1 Turn on the Bluetooth devices under observation, and set up the
master device so it is ready to respond to Inquiry scan. For a typical
recording, ensure that the Master and Slave device(s) are not yet
connected.
Step 2 In the Modes tab under Recording Options, enter the Master
Device’s address.
Step 3
Start BTTracer recording by pressing the
Record button on the toolbar.
Step 4
When the analyzer is able to Sync up to the Piconet Master Clock,
the Green Sync LED in the BTTracer front panel will start
