CHAPTER 6: CATC TRACE FILES

Merlin Mobile displays Bluetooth piconet traffic recording (.blt) files — also known as

Trace™ files — in CATC Trace graphical format.

The CATC Trace display makes extensive use of color and graphics to fully document the

captured data. Individual packets (subactions) are shown on separate rows, with every field

labeled, numbered, and color-coded. Packet rows also display time stamps, idle times,

device roles (master/slave), transmitting frequencies, and the presence of protocol errors.

Built-in or customized higher-level protocol decoding can be easily applied to a Trace to

reveal protocol-specific information. Like packets, individual protocol data is separated into

rows, and labeled, numbered, and color-coded. The Display Options dialog allows you to

control the presentation of virtually every aspect of the data, including the colors, number

formats, fonts, and visibility of specific fields. Many of these options can also be configured

via the Trace file pop-up menus.

The Trace file pop-up menus provide access to many display commands, as well as special

dialogs that contain more detailed information about field contents. Additional information

can also be gleaned from the display’s tooltips.

Finally, Merlin Mobile's search capabilities help you to pinpoint exactly what you're looking

for, even in a large Trace file.

6.1 Display Options

The Display Options dialog box in Merlin Mobile allows you to customize the way that the

elements in Trace files are displayed. The display of almost everything in a Trace can be

defined, from the fonts and colors to the number formats and types of packets and

transactions to show. These settings can then be saved to a display options (.opt) file. You

can load saved settings and apply them to any Trace file.

There are three ways to access the Display Options dialog:

• Click the Display Options icon on the toolbar.

-or-

• Select Setup > Display Options from the menu bar.

-or-

• Right-click anywhere in the Trace display window and select Display Options from

the pop-up menu.

There are four tabs in the Display Options dialog:

• General: the General tab contains options for the zoom level, tooltips, wrapping, and

fonts.

• Colors: the Colors tab is used to customize the color settings for individual fields.
