The JN5179 USB Dongle can be plugged into any USB port of the Raspberry Pi. In
the case where the IP connection will be provided via Wi-Fi, the supplied Wi-Pi adaptor
must be plugged into another USB port of the Raspberry Pi (the Wi-Pi adaptor creates
its own Wi-Fi network). If both the dongle and adaptor are required, the dongle must
be connected to a port via a USB cable to ensure isolation of the two devices.
The IP connection can be to an existing wired LAN or via a new Wi-Fi LAN:

To connect to an existing wired LAN, the supplied Ethernet cable must be used
to connect the Raspberry Pi to a router in the LAN. The LAN must include a
DHCP server to allocate an IP address to the Raspberry Pi. The DHCP leases
in the router will need to be examined in order to determine the IP address
allocated to the Raspberry Pi.

To use a Wi-Fi connection, the Wi-Pi adaptor must be plugged into the
Raspberry Pi. The Wi-Pi adaptor will create its own Wi-Fi network (rather than
join an existing Wi-Fi network). A PC can then interact with the Raspberry Pi by
joining this Wi-Fi network (which has the SSID Iot_GW_NXP). In this case, the
Raspberry Pi is allocated the fixed IP address 192.168.2.1.
The pre-programmed ZigBee Smart Home Demonstration uses a Wi-Fi connection.
1.4 Network Commissioning
A WPAN is started by the Co-ordinator and other nodes can then join the network, as
indicated in
Section 1.2.4 . Network commissioning may also include the following:

Network joining and subsequent network operation may employ security keys
to implement encrypted communications between nodes, to make the network
secure from malicious tampering. NFC commissioning is becoming an
important technique in establishing this security and is supported by the
JN517x-DK005 Development Kit. NFC commissioning is outlined in
Section
1.4.1 .

Once a node has joined a network, it may need to be linked to one or more
other nodes from a functional point-of-view. For example, when a new light is
added to a lighting network, it may be required that a particular light switch
(already in the network) is used to control the new light. There are different
ways of establishing this link and these are described in
Section 1.4.2 .
