Creating a MiWi Network
3.4.1.1
TO CREATE A MiWi NETWORK
Follow these steps to create a MiWi Network:
1.
Configure one node as PAN Coordinator (“Create NWK”) and another as
Coordinator (“Join NWK”).

2.
Use the Coordinator to join the PAN Coordinator, “8-bit Wireless Development

seconds the display changes to:
• RB0: Create NWK
• RB2: Join NWK
3.4.1.1.1
To Configure the node as PAN Coordinator
Follow these steps to configure the node as PAN Coordinator
1.
On one node press RB0 push button to create the network.
After the node is configured as PAN Coordinator, “Created Network
Successfully” message will be displayed on the LCD. After the device is
configured as PAN Coordinator, it measures the temperature sensor for every 30
seconds (the timer can be modified in the application) and updates the LCD with
the temperature information in °C (Celsius) and °F (Fahrenheit). The last three
bytes of the MAC address in HEX format are also displayed on the line two of the
LCD:

To Join the network as Coordinator
Follow these steps for joining the network as Coordinator
1.
On the second node press RB2 push button to join the available networks. This
initiates an active scan command. The available network information will be
displayed on the LCD:

Press RB0 to join PAN Coordinator, with the address of 0x010203, created in the
previous step.

The LCD displays “Joined Network Successfully” message. After the node is
successfully joined the PAN Coordinator, it measures the temperature sensor for
every 30 seconds and broadcasts the information over the network along with its
MAC Address. The LCD is also updated with the temperature sensor reading:
