CATC MERLIN MOBILE 1.00 CHAPTER 5

User’s Manual Recording Bluetooth Traffic

DRAFT

To stop the recording before the recording session is complete, select Record > Stop from

the menu bar, press the Stop button on the standard toolbar, or press the Escape (Esc) key

on the keyboard. Merlin Mobile will stop recording and will upload the data that was

recorded before the recording was interrupted.

5.3 Recording Status

When Merlin Mobile is recording piconet traffic, information about the recording session is

shown in a three-part display on the status bar at the bottom of the Merlin Mobile application

window. The first part shows the recording progress, the second part indicates the recording

state, and the third part displays the signal strength and analyzer state.

5.3.1 Recording Progress

The recording progress field indicates the recording progress via a progress bar. The vertical

black line in the progress field indicates the trigger position.

• Pre-Trigger:

Prior to a trigger event, the recording progress bar is shown in the color that is desig-

nated for pre-trigger packets on the Colors tab of the Display Options dialog. Note: the

recording progress bar won't appear until Merlin Mobile has synchronized with the

piconet and begun recording.

• Post-Trigger:

After a trigger event is detected, the progress bar moves past the trigger line and the

color of the bar changes to the color designated for post-trigger packets. Note: if the

Recording Options are set up for a snapshot recording, the trigger is not used and so the

trigger bar appears on the left edge of the progress field, and the progress bar will be

shown in the post-trigger packet color.

• Uploading:

Once the buffer is filled, or the recording is stopped manually, a thin, white bar appears

in the progress field, representing the progress of the upload.

5.3.2 Recording State

The recording state field reports one of three recording states:

• Trigger?:

If Merlin Mobile has not detected a trigger event, the word “Trigger?” flashes in the

recording state field.
