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", "Sync and Record" can be run with
or without an established piconet.

Note

This mode can only be used with 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 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 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
Master device. When the piconet Master pages Merlin, Merlin obtains the
information necessary for synchronization and then attempts to synchronize
to the piconet controlled by that Master.
