Sync & Record

Sync and Record works just like "Page Sync and Record" except that Merlin
Mobile takes its sync data directly from the Master instead of the Slave
devices. With Sync and Record, Merlin Mobile conducts a General Inquiry
to get hop frequency and clock information from the Master. Merlin Mobile
then waits to detect piconet traffic from the Master device’s piconet. When
the piconet is established, Merlin Mobile 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 Mobile 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 Mobile front panel will start
blinking.

Step 5

Establish connection between the Bluetooth devices under analysis.

Step 6

When Merlin Mobile 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
Mobile enters Inquiry Scan and Page Scan mode and waits for a page from
