Merlin Mobile User’s Manual CATC SW Version 2.0
1. Overview
The CATC™ Merlin Mobile™ Bluetooth™ Protocol Analyzer blends powerful
piconet traffic recording and analysis abilities with compact, easily transportable
PC Card technology. Merlin Mobile is a development and test tool for products
using the Bluetooth wireless technology. Merlin Mobile non-intrusively monitors
piconet traffic and records and displays captured Bluetooth data.
Like its predecessor, the CATC Merlin™ Bluetooth Protocol Analyzer, Merlin
Mobile uses CATC's BusEngine™ technology, which incorporates a real-time
recording engine with programmable data, state, and error detection, and event
triggering, filtering, counting, and sequencing. This enables users to optimize
recording memory usage to capture the data that is most important.
The Merlin Mobile system consists of the analyzer hardware unit and the analyzer
software. The Merlin Mobile analyzer unit monitors and captures baseband packets
on a piconet in a non-intrusive manner. The packets can then be viewed and
decoded with the Merlin Mobile software. The software displays the piconet data in
CATC Trace™ format and is capable of decoding and organizing the data for these
Bluetooth protocol levels: Baseband, LMP, L2CAP, SDP, TCS, RFCOMM,
OBEX, AT, HDLC, PPP, BNEP, HID, AVCTP, AVDTP, IP, TCP, and UDP. In
addition, users can use the CATC Scripting Language (CSL) to create custom
decoders for specific development purposes.
The Merlin Mobile analyzer unit is configured and controlled by the analyzer
software. It can be used with portable computers for field service and maintenance,
as well as with desktop units in a development environment. Furthermore, Merlin
Mobile Automation™ and compatibility with the CATC Merlin's Wand™
Bluetooth Test Generator provide the capability for creating a fully-automated
testing environment.
The Merlin Mobile analyzer includes provisions for on-the-fly detection of, and
triggering on, numerous events. Such events include specific packet headers,
payload headers, data patterns, and many abnormal (error) traffic conditions.
Merlin Mobile continuously records the piconet data in a wrap-around fashion until
it is manually stopped or until the trigger event is detected. Upon detection of a
triggering event, the analyzer continues, as necessary, to record data until the
recording buffer is filled.
The Merlin Mobile application may be used with or without the analyzer box. When
used without the analyzer box, it functions as a CATC Trace™ viewer. As a Trace
viewer, it can be used to view, analyze and print CATC Trace files.
