Device Traffic Filter
The Bluetooth Explorer 400 application provides a powerful
Device Traffic Filter
designed to
allow the user to be very precise in terms of precisely controlling the device traffic displayed
throughout all of the application’s panes.
The
Device Traffic Filter
window
provides a searchable database of all devices captured by the
analyzer, including historically captured devices, located in the
Device Database
tab. Each
listed device includes ancillary information, including LMP Name, BD_ADDR, Radio type, and
Company ID.
The user can use the
Device Traffic Filter
to rename devices with user-defined names, for easy
recognition in other areas of the application, and to re-color the default color associated with
any/each device used throughout the application. Users may also manually add new devices to
the Device Database.
The user can select a device listed in the
Device Database
to edit an
incomplete BD ADDR to fill in missing values, in those cases where the analyzer
capture is started after the connection process occurs. This can possibly assist
with the analyzer’s decryption routines to enable traffic decryption, assuming
all other factors used in the decryption process are known and captured.
The
Traffic Filtering Criteria
tab allows user to select the criteria on which selected devices
will be filtered, as detailed below:
