Example 2: Forming a network with security (obtaining keys during joining)
1. Start a coordinator with the following settings:
a. ID=2235
b. EE=1
c. NK=0
d. KY=0
e. WR (save networking parameters to preserve them through power cycle)
2. Configure one or more routers or end devices with the following settings:
a. ID=2235
b. EE=1
c. KY=0
d. WR (save networking parameters to preserve them through power cycle)
3. Read the AI setting on the coordinator and joining devices until they return 0 (formed or joined
a network).
In this example, EE, ID, and KY are set the same on all devices. Since NK was set to 0 on the
coordinator, a random network key was selected. And since KY was set to 0 on all devices, the
network key was sent unencrypted ("in the clear") when the devices joined. This approach
introduces a security vulnerability into the network and is not recommended.
