Getting started
This section provides a complete description of possible commands and 5 typical use case
scenarios:
Scenario 1: Setting up a ZigBee network
Scenario 2: Sending Unicast and Broadcast messages
Scenario 3: Displaying network parameters
Scenario 4: Modifying the network configuration
Scenario 5: Activating additional security features
Types of networks
ZigBee allows star, tree, and mesh network topologies using one coordinator, multiple
routers and multiple end devices:

Menu commands description
The user interacts with the SN2xx-PRIMER evaluation kit through the LCD and the joystick
available on the coordinator (MB622) board.
By moving the joystick up, down, left or right, the user scrolls through the list of all available
commands displayed on the LCD screen. The screen displays the commands in a circular
menu.
To execute the selected command, press down on the joystick. After the command is
launched, the LCD displays the result of the execution.
ZigBee Coordinator (ZC) is responsible for initiating and maintaining the devices on the
network. All other devices, known as end devices, directly communicate with the
ZigBee coordinator. The coordinator selects an appropriate channel after scanning for
available channels and then selects the PAN ID.
ZigBee Router device (ZR) provides routing services to network devices. Routers can
also serve as end devices. Unlike normal end devices, routers are not designed to
sleep and should generally remain on as long as the network is up.
ZigBee End devices (ZED) are leaf nodes which communicate only with their parent
nodes and, unlike router devices, cannot relay messages intended for other nodes.
Depending on the network topology, end devices can be of several types:
–
–
Table 3
Sleepy end devices power down their radio when idle, and thus save resources.
Sleepy end devices are also sometimes known as RX-off-when-idle devices. This
is a standard ZigBee device type.
Non-sleepy end devices remain powered during operation. These devices are
known as RX-on-when-idle devices. This is a standard ZigBee device type.
