When the device is joined, the Coordinator board displays the Network ID (0x796E, for
example) and the EUI (0080E100000009BE, for example). When the Router board is joined
to a network, LED D1 is active (green).
The SN2X-PRIMER evaluation kit supports also the possibility to add other devices to the
basic SN2xx-PRIMER 2-node network. In this case, the Coordinator LCD displays the
parameters of all devices and the types of messages exchanged with the Coordinator.
For more information regarding networking aspects, please refer to the ZigBee and IEEE
Std 802.15.4 specifications.
Scenario 2: Sending Unicast and Broadcast messages
The ZigBee standard supports two basic types of messages:
●
●
Before sending a message, the application must construct the payload of the message. The
message frame varies according to message type and security levels. Since much of the
message frame is generated outside of the application, the key factor that must be
considered is the maximum size of the originating message payload.
The ZigBee addressing scheme for messages is:
●

Connect jumper SW3 in 1-2 position to switch on the Coordinator board, or press
switch SW2 to reset the board.
Scroll right to enter the first-level menu.
(Optional) Set new default channel value on the Coordinator board.
a)
b)
(Optional) Set new default PAN ID value on the Coordinator board.

b)
Scroll left or right to display Form Network and press the joystick to confirm.
Scroll left or right to display Permit Joining and press the joystick to confirm.
Scroll up or down to select the number of seconds (between 0 and 99) to allow joining
and press the joystick to confirm. If set to 0, joining is disabled. The Coordinator is now
ready to accept requests from other devices that wish to join the network.
On the Router board, connect jumper SW4 in 1-2 position or press switch SW3 to reset
the board. The Router starts to scan channels and will send a request to join available
networks.
Unicast, sent to a specific node ID based on an address table
Broadcast, sent to all devices
EUI-64, a 64-bit globally unique address assigned to each device at manufacturing that
never changes
Network Address: a 16-bit unique network address assigned to each device when it
joins the network; may change (due to conflicts)
Endpoint, is a service point within a ZigBee device, it is 8-bit logical address.
Cluster ID: a 16-bit field defined as “a related collection of attributes and commands”,
which together define a communications interface between two devices. Cluster IDs
and their associated message structures are defined by the application profile.
Scroll left or right to display Set Channel and press the joystick to confirm.
Scroll up or down to display channels and press the joystick to select channel.
Scroll left or right to display Set PAN ID and press the joystick to confirm.
Scroll up or down, left or right to display numbers and press the joystick to select
correct ID numbers.
