Passive Sync & Record with a Private Device Network

Since private device networks do not allow other devices to join the network, Merlin Mobile

needs to temporarily assume the identity of a slave in the network in order to obtain the

information it needs to synchronize with the devices and capture Bluetooth traffic. The real

slave device must be turned off before recording begins.

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

Sync & Record method for a private device network:

Step 1 Open the Recording Options dialog, 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.

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 Enter the slave address for Merlin Mobile in the Page Target combo box.

Step 5 If necessary, configure the remaining Piconet Recording options (for more

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

Step 6 Before beginning the recording, make sure that the slave device is turned off.

Step 7 Select Record > Start from the menu bar or press the record button on

the standard toolbar.

When Merlin Mobile is ready to synchronize with the piconet, the analyzer

state portion of the Recording Status display reads “Syncing...”

Step 8 Direct the master device to initiate a page to the Page Target address. When

Merlin Mobile receives the page, it extracts the information that it needs in

order to synchronize with the piconet and capture the Bluetooth traffic.

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.

Step 9 Once Merlin Mobile is synchronized to the network, turn the slave device on.

When the Master re-pages the Page Target address, the slave will be admitted

into the private network. Since Merlin Mobile is passive in this mode, the

slave and Merlin Mobile do not conflict over the shared address.

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

recording session is complete.
