Changing an OBEX Client or Server Status

If the beginning sequence of traffic is not recorded in a trace, the
client/server status of the transmitting devices will not be preserved in the
trace. In this case, the OBEX Client/Server pop-up menu will become
active and you will be able to change the assignment.

Decoding BNEP

BNEP (Bluetooth Network Encapsulation Protocol) is a protocol that allows
devices to encapsulate network protocols such as IP. Since BNEP can carry
different types of network protocols, you need to tell Merlin II what protocol
the BNEP is going to be carrying. You do this via a script file called
bnep.dec that is read during the initialization of the Merlin II software. This
file tells Merlin II how to decode BNEP fields. Once read, BNEP can be
correctly decoded by pressing the

button on the toolbar. If the decode

file is not read at initialization, Merlin II will display the data in an
undecoded format.

For more information on BNEP decoding, see a supplemental document on
BNEP in the support directory on the CATC web site:

Decoding HID

HID (Human Interface Device) is a profile associated with traffic from
devices such as a mouse or a keyboard. To decode HID traffic, you will
need to tell Merlin II what types of HID traffic it will be recording. You do
this by editing a script file called hid.dec. Merlin II reads this file during the
initialization of the Merlin II software. This file tells Merlin II how to
decode the HID fields. Once read, HID can be correctly decoded by
pressing the

button. If the decode file is not read at initialization, Merlin

II will display the data in an undecoded format.
