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.
