User’s Manual Recording Bluetooth Traffic

DRAFT

Note: In order for this mode to work, the master device must support the inquiry scan substate while

connected to other devices.

The following steps describe how to set up a Piconet Recording session using the Sync &

Record method:

Step 1 Open the Recording Options dialog and select the Modes tab and make sure

that Piconet Recording is selected in the Recording Mode section.

If Piconet Recording wasn't already selected, the options on the Modes tab

will change so that you can configure the piconet recording parameters. If an

Inquiry Recording was performed, the addresses of all Bluetooth master

devices that were discovered will appear in the Master Address drop-down

list.

Step 2 Select Sync & Record from the Sync Method drop-down list.

Step 3 Enter the address of the intended master device in the Master Address combo

box.

If you used Bluetooth Neighborhood or an Inquiry Recording to discover the

device addresses, you may select the address or device name alias from the

Master Address drop-down list. You may also switch the addresses in the

Master address and Page Target lists by pressing the swap button.

Step 4 If necessary, configure the remaining Piconet Recording options (for more

information, please see “Piconet Recording Mode Options” on page 37).

Step 5 Select Record > Start from the menu bar or press the record button on

the standard toolbar.

Now Merlin Mobile will wait for the master to begin paging the slave device.

When paging begins, Merlin Mobile will synchronize to the piconet and

capture the traffic between the devices. The analyzer state message in the

Recording Status display will change to “Act:”, indicating that Merlin

Mobile is fully synchronized to the piconet and is recording traffic.

Merlin Mobile records piconet traffic data and then uploads it as a Trace file when the

recording session is complete.

To stop the recording before the recording session 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.

5.2.4 Make a Manual Passive Sync & Record Piconet Recording

Passive Sync & Record is used with master and slave devices that do not support the inquiry

scan substate while connected to other devices. This method causes Merlin Mobile to enter

the inquiry scan and page scan substates, then wait for the master device to page the address

specified in the Page Target field (described in Step 4 below). When Merlin Mobile receives

the page, it is able to obtain the information necessary for synchronization with the piconet.
