skip ahead if the concepts of any section are already familiar. To keep the reader oriented
in each section, some overlap is necessary.
While it is not required, it is helpful to have the ZigBee and IEEE 802.15.4 specifications
available when reading this book. I’ll sometimes refer to a section or a concept in those
specifications for further reading.
To obtain the ZigBee specification, go to http://www.zigbee.org and click on “ Download
the Specification. ” It is free, and comes in PDF format.
Go to http://standards.ieee.org/getieee802/802.15.html and select “ IEEE 802.15.2-2003 ”
to obtain the 802.15.4 standard in PDF format. There is a new draft standard, IEEE
802.15.2-2006, but ZigBee does not currently use that specification.
The chapters are organized as follows.
Chapter 1, “ Hello ZigBee, ” lays out the basics of ZigBee and its intended use. It describes
the ZigBee Alliance, which is the standards body which defines and promotes the ZigBee
standard worldwide. This chapter also provides the developer with several ZigBee
networking examples, complete with source code.
Chapter 2, “ Deciding on ZigBee, ” helps the developer make technical and marketing
choices about ZigBee, and even helps determine whether ZigBee is the right solution
for any given problem. It provides a concise checklist, with all of the ZigBee factors
that must be considered throughout the entire product life cycle, from inception through
development, deployment, and maintenance.
Chapter 3, “ The ZigBee Development Environment, ” covers the basics of the ZigBee
development environment, and walks the reader through an example, step-by-step, to
help gain a full understanding of what’s involved in the development and debug phase.
This chapter contains information necessary if the reader plans to follow along with the
examples using actual hardware.
Chapter 4, “ ZigBee Applications, ” goes in-depth into application development, including
the fundamentals of ZigBee networks, nodes, addressing, Application Profiles, and the
features provided to the application by the Application Framework (AF) and Application
Support Sub-layer (APS).
Chapter 5, “ ZigBee, ZDO, and ZDP, ” describes the ZigBee Device Object (ZDO) and
how it interacts with and is used by applications, including how to achieve maximum
battery life from ZigBee nodes.
