Manually Assigning Protocols
If a recording does not capture the beginning of a dialog between a Master
and Slave devices, Merlin 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

device is an OBEX client or OBEX server.

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