Sequence
The Hop Sequence menu presents the following three options:
• 79 Hops Standard - This is the option used for
most recordings.
• Reduced Hop - Restricts BTTracer to five hop
frequencies defined in the test mode
specification of the Bluetooth Specification. When Reduced Hop
or Single Frequency is selected, the Sync method is set to Test
Mode and cannot be modified by the user.
• Fixed Frequency - Allows the transmit and receive frequency
ranges to be specified. Selecting this option highlights the "DUT
Xmit" and "DUT Recv" text boxes. When Reduced Hop or
Single Frequency is selected, the Sync method is set to Test Mode
and cannot be modified by the user.
Enter values into the two text boxes to the set the transmit and
receive frequency ranges:
• DUT Xmit Freq, MHz (+2402) – Allows the setting of the
transmit signal for the Device Under Test
• DUT Recv Freq, MHz (+2404) – Allows the setting of the
receive signal for the Device Under Test
Synchronization Method
To record Bluetooth traffic, BTTracer needs to
synchronize to the piconet under observation.
BTTracer does not participate in the piconet
and behaves as a passive listener. It needs,
however, to communicate briefly with the devices in the piconet to learn the
Master clock and frequency hopping sequence.
Synchronization Method options let you configure how BTTracer
synchronizes to the piconet under observation. There are three options:
• Sync and Record
• Passive Sync & Record
• Page Sync & Record
Note If the selected Hop Sequence is "Reduced Hop" or "Single Frequency," the Sync
Method is set to "Test Mode" and cannot be modified by the user.
