Operating Basics
What’s New in Version 2.3
The Tektronix Bluetooth Protocol Analyzer Application Software V2.3 upgrade
adds several important capabilities to the BPA100 Series analyzers, including
support for three new protocol layers. The new features supported in V2.3 are
listed below:
H Support for New Protocol Layers. BNEP (Bluetooth Network Encapsulation
Protocol), AT (Hayes modem command set), and HID (Human Interface
Device) protocols are decoded with a separate tab for each in the application
windows. Along with the Hayes modem command set, V2.3 also supports
some Bluetooth-specific AT commands for headset profile.
H Hardware Trigger In. This connector senses a TTL-level high or low (menu
programmable) signal as a trigger from another Bluetooth Protocol Analyzer,
logic analyzer, oscilloscope, or other test equipment.
H Hardware Trigger Out. This connector outputs a pulse or TTL-level high or
low (menu programmable) signal to trigger a Bluetooth Protocol Analyzer,
logic analyzer, oscilloscope, or other test equipment. This function allows
you to count clocks after a trigger event for logic analysis synchronization.
You can set the Trigger Out to accommodate any specified pattern in a
sequence. When the pattern is matched, the signal is sent.
H Hardware Clock Out. This connector provides a LV-TTL square-wave signal
synchronized to the local Bluetooth clock. The output frequency is 1.6 kHz
(625 s) with a 50% duty cycle. This signal is always present when the Air
Probe is powered on. To verify the signal, connect an oscilloscope.
H Synchronization Wizard. This feature allows users with a minimal knowl-
edge of Bluetooth synchronization to easily synchronize to a Piconet. The
wizard consists of a series of screens that provide the appropriate graphics,
selections, operations (like device discovery), and other information to guide
you through the synchronization setup process.
H Presynchronization Drift Compensation. This feature improves your chances
of synchronizing to a device with a highly drifting clock. By receiving more
than one FHS packet for a particular device over several seconds, the
analyzer can calculate the relative drift of the device under test and use this
information to improve the success of synchronization.
H Application Programming Interface (API). Using this Tektronix client
software, you can control the Bluetooth Protocol Analyzer from a remote
PC.
H Sniff, Hold, and Test Mode. This feature allows the Bluetooth Protocol
Analyzer to follow the Bluetooth Sniff and Hold power modes. It also
BPA100 Series Bluetooth Protocol Analyzer User Manual
1- 1
What’s New in Version 2.3
provides the capability of supporting Test Mode as a slave Device Under
Test (DUT), so you can use the Bluetooth Protocol Analyzer in conjunction
with any Bluetooth tester.
H L2CAP Connection Properties. This feature lists the current L2CAP
connection properties for all L2CAP connections. It also allows you to
change the L2CAP connection type.
H RFCOMM Server Channel Assignments. This feature lists the current
RFCOMM channel assignments for all RFCOMM connections. It also
allows you to manually assign various protocols for “Unknown” RFCOMM
connections.
H Export to *.wav file. This feature supports a post-acquisition process that
scans captured Independent or Piconet mode audio data and creates a .wav
file. You can play back the file on a PC using standard Windows audio
players.
H Advanced Search. This feature provides new search capabilities based on
individual columns and Boolean parameters. Users can mark all packets that
match the search criteria.
H Trigger Loopback Test. You can use this diagnostic test to verify that the
Trigger In and Trigger Out functions are operating properly.
Graphical User Interface (GUI) Enhancements:
H Low Level Trigger (LLT) and Error Packet Generation (EPG) setup has
been redesigned to be more intuitive.
H Show/Hide Packets and Show/Hide Columns selections have moved to
the Packet View Window. User settings affecting these features are now
saved along with the data file and will be active when you reopen the
data file.
H Double--clicking on a column title adjusts the column width to the
maximum length of the text appearing within that column.
H If a log file contains audio data, an audio icon appears in the log toolbar.
Audio data can then be exported as a .wav file and played back using a
Windows Media player or similar tool.
H The Synchronization Statusbar has changed. It now contains one
indicator and the corresponding synchronization status message, only.

Acquiring Piconet Packet Data
Operating Mode
You can operate the Bluetooth Protocol Analyzer in either Independent or
Piconet mode.
Independent Mode. Configured as an independent unit, the B luetooth Protocol
Analyzer does not interact directly in the piconet. Instead, after synchronizing to
the net, it passively monitors and logs all baseband packets transmitted between
the master and the slaves comprising the Piconet. By using the advanced
triggering and filter features, you can identify the data you want to log, and then
analyze it following the session.
Piconet Mode. Configured as a participant in a piconet, the Bluetooth Protocol
Analyzer uses a full-protocol stack and participates as the master or a slave in the
Piconet.
As a master, the Bluetooth Protocol Analyzer logs all baseband packets between
itself and the piconet slave device(s). When set up as a slave, it logs all packets
between itself and the Piconet master as well as between the master and all other
slave devices.
For information on how to configure the analyzer for independent or Piconet
mode operation, see Logging Mode on page 1--12.
Collecting Data
With the Bluetooth Protocol Analyzer you can connect to and create a log
containing all the baseband packets transmitted between Bluetooth devices in a
Piconet. Using the analyzer features you can do the following:
H Operate as a member of a Piconet, as a stand-alone (independent) unit, or
independent with data decryption.
H Select the master or slave to which the Bluetooth Protocol Analyzer is
synchronized.
H Set the duration over which the Protocol Analyzer tries to synchronize to a
Piconet master.
H Capture all baseband packets transmitted within a Bluetooth Piconet,
including packets that are normally not visible to the host such as retransmitted packets. View the status of each packet and estimate the clock and
hop frequency.
H Select specified hopping patterns: Europe/USA, Japan, France, or Spain.
H Transmit and receive on a single user-defined frequency .
H Set a correlation value.

Acquiring Piconet Packet Data
Logging Mode
Before you start a new logging session, decide whether you will operate the
Bluetooth Protocol Analyzer as an active member of a Piconet (either as a master
or as a slave) or as a stand-alone unit that nonintrusively monitors data flowing
across the Piconet.
Piconet Mode. Use this mode with the Bluetooth Neighborhood or HCI Terminal
to set up the Bluetooth Protocol Analyzer as an active participant in the Piconet.
When you start a logging session, the analyzer logs all baseband packets sent
from and received by your computer, whether the Bluetooth Protocol Analyzer is
acting as a slave or a master.
NOTE. You cannot operate the HCI Terminal application and Bluetooth
Neighborhood simultaneously.
Independent Mode. Use this mode to set up the Bluetooth Protocol Analyzer as a
stand-alone unit. When you select this mode, the analyzer displays the Sync Bar
near the bottom of the acquisition window. See page 1--13 for additional
information on the Sync Bar.
Select a synchronization mode:
H Sync to Piconet using master inquiry. In this mode, synchronization is
obtained by performing an inquiry and using the clock information returned
by the master to set the clock of the Bluetooth Protocol Analyzer. You must
identify a master in the Select Master dialog box. See Select Master or Slave
on page 1--14.
In some Bluetooth devices, the clock drifts away when the device is not in
connect mode; this synchronization mode can be troublesome if you want to
monitor negotiations during the connect phase. The problem occurs because
there are often several seconds of delay from the time the Bluetooth Protocol
Analyzer obtains the master clock information until the master actually
connects to the slave. Likewise, if the inquiry scan mode on the Bluetooth
device is not implemented or is disabled during the connection, this mode
cannot be used for synchronization. See Resync on page 1--19.
H Sync to Piconet using a fake connection response. This mode can be used
only during the connection phase, when the Piconet master connects to a
new slave. The analyzer operates as if it were the slave unit selected in the
Select Slave dialog box (see Figure 1--4 on page 1--14) and obtains the
master clock information by initiating a new connection as if it were that
slave. Immediately after the clock information is retrieved, the protocol
analyzer stops transmitting, and the piconet master continues the connection
attempt with the true slave. You must identify a slave in the Select Slave
dialog box. See Select Master or Slave on page 1--14.

H Sync to Piconet using slave inquiry. This mode can only be used during the
connection phase. The Bluetooth Protocol Analyzer listens for the clock
information from the master (sent in the connection phase) to the new
Piconet slave, and does not interfere with the Piconet in any way. In order to
find the clock information on the right frequency, it is necessary to capture
the slave clock. This is done by performing an inquiry to the slave. You must
identify a slave in the Select Slave dialog box. See Select Master or Slave on
page 1--14.
Sync Indication Bar. To activate the Sync Bar, select View > Sync Bar. When you
use Independent mode as the logging mode, the Sync Bar appears at the bottom
of the acquisition window. See Figure 1--3.
Figure 1- 3: Acquisition window Sync Bar
The Sync Bar contains the following indicators to verify the status of the
analyzer connection to the Piconet:
H Gray. Indicates that the analyzer is in an idle state.
H Yellow. Indicates that the analyzer is waiting for an FHS packet from the
master or slave that is needed for synchronization. This indicator is
accompanied by an explanatory message.
H Flashing Yellow. Indicates that the analyzer is synchronized to the master but
has not yet recorded any traffic. This indicator is accompanied by an
explanatory message.
H Green. Indicates the analyzer is synchronized and acquiring data.
H Red. Indicates that a time-out occurred while waiting for traffic. For more
information on time-outs, see Acquisition Timeout on page 1--15.

Acquiring Piconet Packet Data
Select Master or Slave. Click the
box (see Figure 1--2 on page 1--11) to open a Master or Slave dialog box and set
up the options to discover and connect to a Bluetooth device within range. See
Figure 1--4.
H Inquiry Time-out. Select how long the Bluetooth Protocol Analyzer performs
the inquiry process. The default time is 12 seconds. However, you can set the
time from 2 to 60 seconds.
H Inquiry Access Code. Enter an inquiry access code (IAC); there are 64 IACs.
The default is the General IAC (GIAC), which is 0x9E8B33. The remaining
63 access codes are Dedicated IACs (DIACs). You can set any of the 64
IACs. Although the GIAC is normally used, you can use a DIAC in certain
instances.
For example, a group of users might agree to set their devices to a specific DIAC
to make their devices easier to discover in an environment with many Bluetooth
devices.
H Discover. Click this button to carry out device discovery and display a list of
all active Bluetooth devices within range.
H Select. Click the device name you want to synchronize to; then click Select
and close the Select Master or Select Slave dialog box.

Acquisition Time-out. The Bluetooth Protocol Analyzer invokes a synchronization time-out under the following conditions.
H Acquisition Setup Dialog Box Timeout. Click Acquisition > Setup.Inthe
Timeout (sec) field specify a number in the drop-down list box to limit the
amount of time the analyzer will wait for traffic to start after synchronizing
to a Piconet. If the analyzer is synchronized to a Piconet, and no traffic exists
on the Piconet for too long a time period, clock drift between the analyzer
and the master device may cause loss of synchronization.
H Loss of Piconet Synchronization Time-out. The Bluetooth Protocol Analyzer
will also time out if the analyzer cannot synchronize within a 41 second
period. In this case, user intervention may be required. For example, you
may have to move the undiscovered device closer to the analyzer or reorient
the Bluetooth Protocol Analyzer Air Probe antenna, and then try again. In
some cases, you may have to remove another source of radio interference.
NOTE. When you operate the Bluetooth Protocol Analyzer and Bluetooth
Neighborhood together to participant in a Piconet, you must use Piconet mode.
When you operate the Bluetooth Protocol Analyzer in Independent Mode
working as a passive listener, you cannot use Bluetooth Neighborhood.

H Authentication. Use Authentication to decrypt encrypted data transactions
from bonded (paired) devices where a link key has been previously
calculated. You must enter the Link Key, a 128-bit hexadecimal number,
along with the master and slave Bluetooth device addresses of the devices
for which decryption is desired.
H Pairing. Use Pairing for unbonded devices when the acquisition will record
the pairing process using PIN codes. In this case, you must enter the PIN
code (optionally using an ASCII entry) used between the master and slave
for authentication.
