Appendix C – Frequently Asked Questions
Q. Why is the USB driver is not loading?
A. If the controlling PC does not detect the presence of the rear USB port on the analyzer (or if
the driver otherwise fails to install), the user can manually install the USB driver by going to the
operating system's Device Manager, typically located in the Windows Control Panel, selecting
the attached Ellisys analyzer, and manually pointing via "Update Driver" to the Ellisys "Drivers"
folder which installs with the Bluetooth Explorer application. This folder is typically located in
your Program Files folder at [path]\Ellisys\Ellisys Bluetooth Analyzer\Drivers.
Q. How do I hide traffic?
A. A wide variety of filtering options are available. Please consult Chapter 8 Display Filters for
more information about filtering or see Expert Note EEN_BT08, Separating the Wheat from the
Chaff, located on the Welcome page of the application.
Q. Does the analyzer use the clock from the master device or otherwise participate
actively in the Piconet?
A. The BEX400 is purely passive. It does not require synchronization with any device under
test and does not in any way participate actively in the Bluetooth environment.
Q. What do I need to do in order to update the software?
A. If your PC is connected to the Internet, go to the Help menu and select "Check for Updates."
Otherwise, please contact support@ellisys.com or visit the Downloads section on the Ellisys
website at www.ellisys.com to request the latest software.
Q. Is there a cost for upgrading the software?
A. There is never a cost for software updates. These are provided without cost for the life of
the product.
Q. Does the position of the antenna have an effect on the capture?
A. The position of the analyzer's antenna as well as the position of the device's antenna is
pretty important for getting optimal captures. Each antenna has a specific radiation pattern
which needs to be known in order to avoid blind spots. Please consult the Ellisys EEN_BT05 -
Understanding Antenna's Radiation Pattern Expert Note to get more information about
antennas.
Q. Is there an optimal placement of devices that I am analyzing?
A. Please consult the Ellisys EEN_BT04 - Optimal Placement of Your Analyzer Expert Note to get
more information about optimal placement.
