additional parameter NK (network encryption key) that can be set. When set to the
default value of zero, a random network encryption key is used. Alternatively, a key
can be selected and entered. Leaving NK at the default value is recommended. Setup
of a coordinator in X-CTU is shown in Figure 7.13.
EXPANDING YOUR REACH
Using nothing but XBee Series 1 adapters, penetration tests can be performed from
up to a mile away under ideal circumstances. Depending on the amount of metal and
other materials between the command console and hacking drones, the attack range
can be significantly less than a mile. Doing a penetration test poolside at the hotel
down the street from your target is good. Staying at the nicer hotel a few miles away
or performing the test from another city is even better.
IEEE 802.15.4 ROUTERS
Using Series 2 adapters can conserve power by allowing end devices to sleep the
majority of the time. Each end device must have a parent that is either a router or
a coordinator. The coordinator should be attached to the command console.
