5.2.1 Make a Manual Inquiry Recording

The Inquiry Recording mode causes Merlin Mobile to perform an inquiry to detect

Bluetooth devices within range. Additionally, the device addresses that are discovered will

be inserted into the Master Address and Page Target drop down lists for Piconet Recording.

This makes Inquiry Recording a useful initial step for configuring a Piconet Recording.

To manually record inquiry data:

Step 1 Set up Recording Options or load a Recording Options file.

Note: The Recording Mode must be set to Inquiry Recording on the Modes tab of

the Recording Options dialog. For more information, please see “Inquiry

Recording Mode Options” on page 36.

Step 2 Select Record > Start from the menu bar or press the record button on

the standard toolbar.

Merlin Mobile records all the inquiry data and then uploads it as a Trace file when the

inquiry is complete.

To stop the recording before the inquiry is complete, select Record > Stop from the menu

bar, press the Stop button on the standard toolbar, or press the Escape (Esc) key on the

keyboard. Merlin Mobile will stop recording and will upload the data that was recorded

before the recording was interrupted.

5.2.2 Make a Manual Page Sync & Record Piconet Recording

Page Sync and Record is the recommended method of recording piconet traffic. With this

method, the recording process is started before a piconet is established. Once the piconet is

established, Merlin Mobile waits for the master to begin paging the slave devices. When

paging begins, Merlin Mobile synchronizes to the piconet and captures the Bluetooth traffic.

Note: In order for this mode to work, the intended master and slave devices must support the inquiry scan

substate while connected to other devices.

The following steps describe the simplest way to set up a Piconet Recording session using

the Page Sync & Record method:

Step 1 Place both the intended master device and its first intended slave device into

inquiry scan mode.

Step 2 Perform an Inquiry Recording in order to discover the device addresses.

Note: If you already know the device addresses that you want to use, you can skip

this step.

Step 3 Open the Recording Options dialog, select the Modes tab, and make sure that

Piconet Recording is selected in the Recording Mode section.
