right for it to synchronize with the master device. Subsequent screens may

indicate that the Recording Wizard has encountered the following

Synchronizing — Merlin Mobile is able to enter the synchronizing state. At

this time you should establish a piconet with the master and slave devices.

Once the piconet is established, Merlin Mobile will synchronize and capture

the piconet traffic.

Recording — Merlin Mobile has synchronized to the piconet and is now

recording traffic.

Repeat — The recording is complete. When the recording is complete, the

captured data will be uploaded to the PC as a CATC Trace. Press Repeat to

make another recording using the same configuration.

Retry — Merlin Mobile was not able to enter the synchronizing state. Press

Retry to try again. Here are some possible problems that can prevent Merlin

Mobile from entering the synchronizing state:

• The devices do not support the inquiry scan substate while connected to

other devices.

• The device addresses were not configured correctly.
