4.2 End Device
Association &
Network
Configuration
As each End Device is turned on, it performs an active scan of all channels from 11 to
26, broadcasting a Beacon Request and recording all information that it receives from all
PAN Coordinator beacons. The End Device will then select the channel that corre-
sponds to the PAN Coordinator with the correct PAN ID value that it is searching for.
The End Device will attempt to “associate” to the PAS Coordinator. Sucessful associa-
tion will result in a network address assignment to the End Device. By default, the
software in this kit assigns the first associated End Device the function of LED (output),
the second associated End Device the function of Switch 1 (input), the third – Switch 2,
and the fourth – Switch 3. Pressing SW1 on the PAN Coordinator completes the config-
uration of the network and allows the End Devices to operate as defined.
4.3 Network
Operation
Now that the network configuration is complete, pressing the pushbutton switch (T1) on
the End Device corresponding to Switch 1 will send a message to the PAN Coordinator
to notify the End Device corresponding to LED, D1, to toggle its state. Similarly, End
Devices corresponding to Switches 2 and 3 control LEDs D2 and D3 respectively. Addi-
tional End Device information is captured and displayed on the LCD screen during
normal network operation. This includes the total number of times Switch 1, 2, and 3
were pressed, the power level in dBm of the received packet betwen the End Device
and the PAN, as well as the current state of each LED. Additional details with regard to
changing the network configuration are described in the next section.
