Merlin II Protocol Analyzer User’s ManualCATC SW Version 2.30

To the right of the Sync Method menu are two menus which let you select

or enter address for the devices in the piconet:

Master Address - Presents a drop-down list of Master devices found

previously. You can also enter address values in this box.

Page Target -- Presents a drop-down list of Page Target devices found

previously. You can also enter address values in this box.

Between the two text boxes is the following button:

- Swaps the Master and Page Target addresses.

When to Use the Different Piconet Recording Modes

Page Sync & Record is the preferred option and should be used whenever

possible. If Page Sync & Record can not be used, then Sync & Record

should be used. Passive Sync and Record should be used only if the first

two options can not be used.

Sync & Record

Sync and Record works just like "Page Sync and Record" except that Merlin

II takes its sync data directly from the Master instead of the Slave devices.

With Sync and Record, Merlin II conducts a General Inquiry to get hop

frequency and clock information from the Master. Merlin II then waits to

detect piconet traffic from the Master device’s piconet. When the piconet is

established, Merlin II is able to synchronize to the Master and begin

recording. In contrast to "Page Sync and Record", "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 II recording by pressing the

Record button on the toolbar.

Step 4 When the analyzer is able to Sync up to the Piconet Master Clock,

the Green Sync LED in the Merlin II front panel will start

blinking.
