User’s Manual Recording Bluetooth Traffic

DRAFT

Perform Inquiry Now — This option causes Merlin Mobile to perform a

general inquiry to discover local Bluetooth devices. Devices that are

discovered will then be listed on the screens for Steps 6 and 8.

Skip Inquiry — This option skips the inquiry and takes you straight to Step 6.

Step 3 Device Search Type: Choose one of these options:

I want to search for all Bluetooth devices within range. — This option causes

Merlin Mobile to search for all local Bluetooth devices.

I want to search only for devices in the search group corresponding to the

following (hexadecimal) DIAC — This option causes Merlin Mobile to

search only for devices that use the 24-bit Dedicated Inquiry Access Code

(DIAC) that you enter.

Step 4 Device Search Duration: Enter a value to set the number of seconds that

Merlin Mobile will search for local Bluetooth devices. The value can be set

between 1 and 80 seconds.

Step 5 General Device Search: Merlin Mobile performs the device search, then

gives you two options:

Repeat — Press this button to make Merlin Mobile repeat the search.

Show Devices Found — Press this button to view the search results in the

Bluetooth Neighborhood window.

Step 6 Device Address (master device): Select or type the address or device name

alias of the intended master device in the combo box on this screen.

The combo box lists addresses only for those devices that it has recently

encountered via a device search.

Step 7 Record Existing Piconet: Choose at least one of these options:

My piconet master device will respond to inquiries from other devices while

it is in a connected state. ('Sync & record' mode) — The Sync & Record

method of recording piconet traffic causes Merlin Mobile to perform an

inquiry to obtain synchronization information from the master device. Then,

Merlin Mobile can synchronize to the piconet and capture the traffic between

the devices. In order for this mode to work, the master device must support

the inquiry scan substate while connected to other devices.

My piconet master device can establish a piconet consisting of more than one

slave device. ('Passive Sync & Record' mode) — 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 for the page target (slave) device.

When Merlin Mobile receives the page, it is able to obtain the information

necessary for synchronization with the piconet.

Note: Selecting both options will cause Merlin Mobile to use the Sync & Record

synchronization method.
