Merlin Protocol Analyzer User’s ManualCATC Version 1.6
Note If the "sync" light on the front of Merlin does not change from flashing to solid it
means that Merlin did not synchronize with the piconet when it was established.
Sync & Record
Sync and Record works just like "Page Sync and Record" except that Merlin
takes its sync data directly from the Master instead of the Slave devices.
With Sync and Record, Merlin conducts a General Inquiry to get hop
frequency and clock information from the Master. Merlin then waits to
detect piconet traffic from the Master device’s piconet. When the piconet is
established, Merlin is able to synchronize to the Master and begin recording.
In contrast to "Page Sync and Record", "Page Sync and Record" can be run
with or without an established piconet.
Note This mode can only be used to find master devices that support Inquiry Scan.
To perform a "Sync and Record", follow the steps below:
Step 1 Turn on the Bluetooth™ devices under observation, and set up
the master device so it is ready to respond to Inquiry scan. For
a typical recording, ensure that the Master and Slave device(s)
are not yet connected.
Step 2 In the Modes tab under Recording Options, enter the Master
Device’s address.
Step 3 Start Merlin recording by pressing REC icon in the toolbar.
Step 4 When the analyzer is able to Sync up to the Piconet Master Clock,
the Green Sync LED in the Merlin front panel will start blinking.
Step 5 Establish connection between the Bluetooth™ devices under
analysis.
Step 6 When Merlin senses Piconet traffic, the Green Sync light
goes ON solid, recording starts and the status bar in the
bottom of the analyzer screen shows activity.
Recording may be stopped manually or when the recording buffer is filled.
Note After the Sync light starts blinking, a connection between the Bluetooth™ devices
should be established within one (1) minute.
Passive Sync & Record
Passive Sync and Record is used in situations where the Master device and
slave devices do not support Inquiry Scan mode. When selected, Merlin
enters Inquiry Scan and Page Scan mode and waits for a page from the
