CATC MERLIN MOBILE 1.00 CHAPTER 5

User’s Manual Recording Bluetooth Traffic

DRAFT

• De-whitening Off — When De-whitening Off is selected, Merlin Mobile will try to

synchronize without de-whitening the received packets, and assume that they were

transmitted un-whitened.

After Merlin Mobile has synchronized to the piconet, it should follow changes in the

whitening scheme and dynamically track whitened and non-whitened traffic.

If you stopped a recording and want to start another recording of the same piconet, be

aware that Merlin Mobile might still be synchronized to the piconet. Since Merlin Mobile

dynamically follows whitening scheme changes, it will not use the initial de-whitening

state unless the Force Re-Synchronization option is enabled.

• Force Re-Synchronization: When this option is enabled, Merlin Mobile will re-synchro-

nize with the piconet at the start of each piconet recording session.

When this option is disabled, Merlin Mobile uses the data from the piconet that it last

analyzed, thereby bypassing the synchronization process and saving a few seconds from

the beginning of the trace. If you know that Merlin Mobile’s data is correct, you can leave

this option disabled and Merlin Mobile will try to use the existing data. If the data is

incomplete or incorrect, however, Merlin Mobile will automatically perform a refresh.

By default, Force Re-Synchronization is disabled.

• Follow Master/Slave Switch: If enabled, this option allows Merlin Mobile to follow a

role switch between a master and slave device. It is disabled by default.

• Match Clock Rate: This option causes Merlin Mobile to do a general inquiry to deter-

mine the Page Target's clock rate before attempting to synchronize to the piconet. This

is a useful option if the master device's clock is inaccurate. This option only applies for

the Page Sync & Record method of piconet recording.

• Show Paging Traffic: This option causes Merlin Mobile to capture paging traffic

between the master and slave devices. It is available only when using the Page Sync &

Record method of piconet recording.
