BTTracer Protocol Analyzer User’s ManualCATC Version 1.0
Recording Mode
To record Bluetooth™ traffic, the BTTracer analyzer 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.
To synchronize to the piconet under observation, BTTracer can be set up in
different recording modes: Inquiry Recording and Piconet Recording.The
option you select affects the types of settings that display in the window.
Inquiry Recording
Selecting the "Inquiry Redcording" button causes the Modes window to
display the options shown in the previous screenshot.
The "Inquiry Recording" option presents two choices for recording
Inquiries: "General (Unlimited)" and "Dedicated (Limited)."
General (Unlimited)
"General" means "General Inquiry" and is used to search for ALL
Bluetooth™ devices that are within range, for the amount of time specified
in the Inquiry Timeout field. Completion of the inquiry process is indicated
by illumination of the "trigger" light on the front of the analyzer. All
responding packets will be displayed when data upload from the analyzer
completes.
Dedicated (Limited)
"Dedicated" means a specific class or group of Bluetooth™ devices
(designated by the DIAC field of the Recording Options dialog). Selecting
"Dedicated" causes BTTracer to search for all devices from a specific class
or group that are within range, for the amount of time specified in the
Inquiry Timeout field. Completion of the inquiry process is indicated by
illumination of the "trigger" light on the front of the analyzer. All
responding packets will be displayed when stop is selected.
