Note The scale is not linear and affords more granularity in the smaller buffer sizes.
Trigger Position
The Trigger Position slide bar sets the amount of
post-trigger recording that BTTracer will perform. It
also allows adjustment of the location of the trigger
within the defined buffer. You can adjust the
Triggering Position between 1 and 99% post-Trigger.
Trigger Position is available only when Manual Trigger or Event
Trigger is selected as Recording type.
As an example, if the buffer size is set to 16MB, then for the following
Trigger Position settings, the amount of pre- and post-Trigger data is
• 95% post-triggering: 0.8MB pre-trigger, 15.2MB post-trigger
• 75% post-triggering: 4MB pre-trigger, 12MB post-trigger
• 50% post-triggering: 8MB pre-trigger, 8MB post-trigger
• 25% post-triggering: 12MB pre-trigger, 4MB post-trigger
• 5% post-triggering: 15.2MB pre-trigger, 0.8MB post-trigger
Note When a Trigger occurs, recording continues until the post-Trigger amount of the
buffer is filled.

Bluetooth traffic is recorded: Piconet, which configures piconet recording
sessions, and Inquiry which configures inquiry recording sessions.
For recording in Piconet mode, the Piconet page lets you specify the type of
piconet you will be recording and how BTTracer should synchronize and
record the piconet.
The Piconet page divides into a right and left half. Each half displays a set
of options for configuring a BTTracer probe. The right-hand set of options
