Capturing Traffic
Bluetooth and Bluetooth Low Energy (Bluetooth Smart) traffic in the vicinity of the analyzer,
raw spectrum energy, and/or HCI, WCI-2, Audio I2S, HCI Injection, and logic signal traffic
attached to the analyzer is not recorded until the user takes action to capture this traffic (simply
by clicking the
Record
button in the analyzer software).
An alternative browser-based remote capture feature is also provided (see Section 6.9, Taking
Captures Using the Web Control Interface).
Traffic captured by the analyzer is temporarily buffered on the analyzer hardware then uploaded
over the USB connection to the hard drive on the controlling computer, giving the user
extremely long capture depth. For even longer capture depth, an automatic segmentation
feature allows the user to automatically segment one long capture into smaller, more
manageable captures.
The analyzer is designed such that no configuration is required in order to take a capture,
although the
Recording Options
menu provides for inclusion and exclusion of selected traffic
types as well as an optional user-designation of pins to be used for captures taken using the IO
connector on the back of the unit.
When a recording is initiated, the front panel Operating LED will be illuminated.
The BR/EDR and LE LEDs near the Capture antenna port will illuminate
whenever BR/EDR or LE traffic is present in the vicinity of the analyzer,
irrespective of whether a recording has been initiated.

Analyzer Hardware Setup
The basic setup for taking a recording is as shown below. The analyzer is connected over a USB
high-speed connection to a computer that hosts the analyzer application. The USB connection
is used to program the analyzer for any capture characteristics selected by the user, and to
upload traffic to the analyzer application.
To prevent damage to the analyzer, DO NOT over-tighten the antenna when
connecting it to the analyzer. Screw on the antenna to a light finger-tight
