User’s Manual Decoding Trace Data

DRAFT

To find out whether a connection assignment was taken from the recording,

manually assigned, or is unassigned, click on an item in the Master list. The

assignment source will be shown in the Slave channel information area

below the list. Assignments that were not taken from the recording can be

configured by the user.

Step 3 To change unassigned or manual assignments, select an address from the

Am_Addr drop-down list, then choose a master channel from the Master list.

Select a slave channel in the Slave list, then click the Connect or Disconnect

button.

The Trace will update to reflect the new assignments.

7.3.3 RFCOMM Channel Decoding Assignments

The RFCOMM Channel Assignment dialog is used to manually configure RFCOMM

channel assignments (DLCIs) for decoding RFCOMM commands.

Manual assignments are saved with the Trace, so they will be used the next time the Trace

is opened and RFCOMM commands are decoded.

RFCOMM Channel Assignment dialog

This dialog shows the current RFCOMM channel assignments for the active Trace file, and

also provides a way to configure unassigned and manually assigned channels.

The columns of data in the list contain this information:

• From message #: The RFCOMM command row # for each master or slave transmission

in the Trace that first uses the particular DLCI.

• AmAddr: The Active Member Address (AM_ADDR) for the device.

• dlci = #: The Data Link Connection Identifier (DLCI).

• Protocol name: The protocol currently assigned for the channel. ‘- ??? -’ indicates that

the channel is unassigned.

To access the dialog and configure channel assignments:

Step 1 Decode RFCOMM commands in a Trace by selecting View > Levels >

RFCOMM Message Level from the menu bar, or by pressing the RFCOMM

button on the toolbar.

RFCOMM commands will be decoded by Merlin Mobile.

Step 2 Open the RFCOMM Channel Assignment dialog by selecting View >

RFCOMM channel assignments from the menu bar, or by right-clicking

anywhere in the Trace and selecting RFCOMM channel assignments from

the Trace View pop-up menu.

The dialog will open.
