CATC MERLIN MOBILE 1.00 CHAPTER 5

User’s Manual Recording Bluetooth Traffic

DRAFT

Step 4 Set the inquiry type. The Inquiry Type for an inquiry recording can be set to

one of two options: General (Unlimited) or Dedicated (Limited).

• General (Unlimited) — Selecting this option causes Merlin Mobile to use

the General Inquiry Access Code (GIAC) to perform a general inquiry to

search for all Bluetooth devices that are within range.

• Dedicated (Limited) — Selecting this option causes Merlin Mobile to use

a Dedicated Inquiry Access Code (DIAC) to perform a search for a

specific class or group of Bluetooth devices.

When this option is selected, the DIAC LAP text box appears so that the

user can supply the DIAC that Merlin Mobile should use.

Step 5 Set additional settings:

• Correlation Value — This value tells Merlin Mobile how many bits of a

packet’s sync word must be received correctly in order for the packet to

be considered valid. For instance, setting the value to 43 means that at

least 43 of the 64 bits available in the sync word need to be correct to

qualify as a valid packet. The value must be an integer between 33 and 64.

The default value is 57 bits.

• Inquiry Timeout — This value specifies how long Merlin Mobile will

transmit the inquiry message to look for Bluetooth devices. The value

must be an integer between 0 and 80. The default value is 20 seconds. An

Inquiry Timeout value of zero will cause Merlin Mobile to perform the

inquiry operation continuously, until manually stopped by the user.

Step 6 (Optional) Enable CATC debug file. When this option is selected, Merlin

Mobile will create a file that can be used by CATC Support to aid in

debugging. This option should always be disabled unless otherwise directed

by CATC personnel.

Step 7 Click OK to use the settings and close the Recording Options dialog

-or-

Continue configuring the recording options on the General, Events and

Actions tabs.

Note: You may also save the settings as a Recording Options (.rec) file. This will allow you to load the file

whenever you want to use those settings.

Piconet Recording Mode Options

Making a recording using Piconet Recording mode causes Merlin Mobile to monitor and

record piconet traffic. Merlin Mobile records the traffic data as specified in the Recording

Options, then uploads the data as a Trace file when the recording is complete.

To set parameters for a Piconet Recording:

Step 1 Open the Recording Options dialog and select the Modes tab.

Step 2 In the Recording Mode section, select Piconet Recording.
