4.1 Bluetooth Neighborhood

Bluetooth Neighborhood is used to find information about Bluetooth devices in the local

area.

• Access the Bluetooth Neighborhood window by clicking the Bluetooth Neighborhood

button on the toolbar, or by selecting View > Bluetooth Neighborhood from the

menu bar.

The Bluetooth Neighborhood command causes Merlin Mobile to start recording, perform a

general inquiry to detect local Bluetooth devices, and then display information about the

devices in the Bluetooth Neighborhood window. The information includes the device

address (BD_ADDR), clock frequency (in hertz), and class of device (CoD). Merlin Mobile

also uploads the inquiry traffic data as a Trace.

If you have created device name aliases, those names will show up in parentheses following

the BD_ADDRs. The device addresses or names are also included in the drop-down lists of

device addresses in the Recording Options dialog and Recording Wizard.

4.2 Device Name Aliases

An alias can be created for any device so that it can be referred to by a name instead of its

numeric address. Device name aliases are displayed in Bluetooth Neighborhood and in

drop-down lists of device addresses in the Recording Options dialog and Recording Wizard.

The file BTnames.txt (Figure 4-1) is used to associate the device BD_ADDRs with the text

names. This file is located in the directory where the Merlin Mobile application was

installed. There is no limit to the number of aliases that can be added to the file.

The names must be 12 characters or less in length. If the name is longer than this, Merlin

Mobile will truncate the name at 12 characters. The names may contain spaces and any

combination of characters.

To create a device name alias:

Step 1 Open BTnames.txt in a text editor.

Step 2 Add a new line at the end of the file and, following the example, place the

device address to the left of equal sign and the alias at the right side.

Step 3 Save the file.
