Step 1) Configure
Your XBee to
Join a ZigBee
Home
Automation
Network.
Each ZigBee profile has
stringent security
requirements that must be
met before a device is
allowed to join a network.
Your Smart Things hub uses
the ZigBee Home
Automation profile security
model, so we will need to
configure our radio to meet
those specs. To make a
ZigBee network secure,
each network generates its
own unique network encryption
key used to encrypt network
packets. Your device must have
this key to communicate, and that
is all taken care of during the
network “join” process.
The ZigBee coordinator’s
(Smart Things hub) primary role
during a join is to give your radio
the network key and allow it to
join the network. To get the
network encryption key from the
coordinator, our radio must be
configured with the proper trust
center link key. Think of it as a
password you must give the
coordinator before it will give you
the network encryption key.
To configure your XBee radio,
you will need to plug the XBee
into your computer with the XBee
USB adapter board. If you haven’t
done so, assemble your XBee USB
adapter board and Load Digi’s
XCTU software. You can
download it from
www.digi.com/products/xbee-rf-solutions/xctu-software/xctu. You
will also need to download the
XBee’s configuration file
