Merlin Protocol Analyzer User’s ManualCATC Version 1.6
The right area is context sensitive -- the Event Group selected in the Center
area will determine what events will display on the right. For example, if
you select Packet Type, the Right area will show you a list of packet types.
Bold entries in the list represent items that actually occurred in the trace.
In the screenshot shown above, for example, AM Address is selected. On
the right, you see that only Address 1 is in bold. This indicates that only a
single device was transmitting traffic in the displayed trace.
Event Groups
Event Groups are categories of events that can occur in a trace. Clicking on
an Event Group will display a list of Event types on the right side of the Find
window that occur within each Event Group.
AM Address
Contains a list of seven Active Member addresses. Bold entries represent
devices that occur in the trace.
Master/Slave
Contains two options labeled Master and Slave. Selecting an option will
cause Merlin to search for traffic based on the selected role.
Packet Type
Contains a list of all Bluetooth packet types. If a packet type occurs in the
trace, it will appear in bold.
Acknowledge
Contains a list of three Acknowledge types: Explicit NACK, Implicit
NACK, and ACK. The three Acknowledge types are responses a device
can issue to attempts to transmit packets to it.
A device can send an Acknowledgment in two ways: through setting the
ARQN field to 0 (= explicitly not acknowledged), to 1 (explicitly
acknowledged) or by sending an empty packet that does not have an ARQN
field (= implicitly not acknowledged).
Explicit NACK - Explicitly not acknowledged. An Explicit NACK is an
explicit response by a device that it did not receive a data packet. The
Explicit NACK is transmitted in the ARQN field (=Acknowledgment
Request Negotiation field). ARQN=0 means ’Explicit NACK.’
Implicit NACK - Implicitly not acknowledged. An Implicit NACK is a
NACK that is implied rather than explicitly stated. If a device responds
to a data packet by sending an empty packet, the NACK is implied.
ACK - Acknowledged. If a data packet is successfully transmitted to a
target device, the target device acknowledges the received packet by
