Running "Passive Sync and Record" with Private Device Piconets
Because private device networks do not allow other devices to join the
network, Merlin needs to temporarily assume the identity of a slave in the
network in order to join that network. To do this requires disabling the slave
and beginning the operation without an established piconet. The following
steps show the process.
Step 1 Turn the Master device on and the slave device off. You
need the slave device turned off so that Merlin can take its
place in the piconet.
Step 2 Enter the slave’s address into Merlin’s "Page Target" field in
the Modes tab in the Recording Options dialog box.
Step 3 Run "Passive Sync and Record." The Master will then page
the slave’s address and Merlin will be able to sync.
Step 4 When Merlin synchronizes to the Master, turn the slave back
on. When the Master re-pages the address the slave will be
admitted into the private network. Since Merlin is passive in
this mode, the slave and Merlin do not conflict over the
shared address. Merlin is then able to record the traffic
between the Master and slave.
Test Mode
Test Mode allows you to set Merlin’s Hop Frequency to a some preset test
frequencies. When "Test Mode" is selected, the parameters marked
"Limited Hop" and "Single Frequency" in the list under “Hop Frequency”
(described below) become selectable.
Hop Frequency
Until recently, local regulations in Japan, France, and Spain defined a
Bluetooth™ frequency range that was different than the range used by the
rest of the world. We have included the selections for organizations for
testing of devices developed before all frequencies were made available on
a world-wide basis.
To set Merlin to the correct Hop Frequency, select from the drop-down
menu one of the following choices:
•79 Hops Standard
• 23 Hops Japan
• 23 Hops Spa

• 23 Hops France
• Limited Hop - When "Test Mode" is selected (see above), the
