Manually Assigning Protocols
If a recording does not capture the beginning of a dialog between a Master
and Slave devices, Merlin Mobile may not have the L2CAP messages it
needs to determine the correct protocol assignments. In this case, L2CAP
messages will display an "N" in the Assignment field that means "Not
Assigned.
"
If you know what the protocol assignment should be for the missing
assignments, you can manually add them by right-clicking your mouse over
the A field shown above and selecting from the pop-up Assignment menu
shown on the previous page.
Other Assignments: OBEX Client/Server Status
OBEX messages carry a status that indicates whether the transmitting
device is an OBEX client or OBEX server.

"OBEXsample.tfb" in C:\Program files\CATC\Merlin
