for them. In addition, routers can pass messages alone the network.
The coordinator is a router that also has a network management role.

MAC - Medium Access Control
Reliable communications between neighbors
Each end device can have up to 240 endpoints, which
are separate applications sharing the same radio. For
example, a three-gang light switch would have two

distinct endpoints sharing the same radio electronics
and battery.

The ZigBee stack is loosely based on the Open
Systems Interconnection model. Referring to figure 6,
the basic tasks of each layer in the stack are as follows:
Physical Layer (PHY): The PHY layer consists of a half
duplex IEEE 802.15.4 radio transceiver. Pixie uses the
16-channel 2.4GHz ISM band, which is the most widely
accepted worldwide.
Medium Access Control (MAC): The MAC layer
provides reliable, error-free communications between a
node and its immediate neighbors.
Network Layer (NWK):
The NWK layer provides the
routing and multi-hop capability required to turn MAC-
level communications into a star, tree or mesh network.

Figure 5. Binding connects compatible ZigBee endpoints to
each other. The coordinator stores the binding table.
Application Support Layer (APS): The APS layer routes
messages on the network to the different application
end points on the node.
Applications Objects:
An application object is the
software at an endpoint which achieves what the device
is designed to do.
The coordinator also manages the Binding Table This
saves an endpoint such as a light switch from knowing
which other endpoints ( i.e. light) it is connected to. The
coordinator, and possibly the routers, store this
information for the end devices in a lookup table.
Endpoints are associated by adding entries to this
lookup table in a process known as binding (Figure 5).
FlexiPanel Ltd has a continuing program of firmware
development for Pixie devices. In general, firmware is
provided free for use with Pixie devices.
ZigBee Device Object (ZDO): The ZDO is a special
application object responsible for overall device
management, security keys and security policies. Its
ZigBee Device Profile (ZDP) is always end point zero,
while other application end points are numbered 1 to
240.
Security Services: The security services provided for
establishing and exchanging security keys to secure the
communications. The MAC, NWK and APS layers use
them for encrypting data prior to transmission and
authenticating it when it is received.
Firmware Development guide
In most applications, nodes will be divided into full
function devices (FFDs) implemented on Pixie modules
and reduced function devices (RFDs) implemented on
lower-cost Pixie Lite modules. Routers and
coordinators need to be mains-powered FFDs, whereas
