Advanced radio settings
 Transmit Power Level: Sets the power level at which the RF module transmits
conducted power.
 Allows Join Time: Determines how long a Coordinator or Router will allow
other devices to join it. If set to 255, devices can join at anytime. (This setting is
supported on Coordinators and Routers only.)
 CCA Threshold: Sets the CCA (Clear Channel Assessment) threshold. Prior to
transmitting a packet, a CCA is performed to detect energy on the channel. The
packet will not be transmitted if the detected energy is above the CCA
threshold.
 Random Delay Slots: Sets the minimum value of the back-off exponent in the
CSMA-CA algorithm for collision avoidance. If set to zero, collision avoidance
is disabled during the first iteration of the algorithm.
 Broadcast Hops: Sets the maximum number of hops for each broadcast date
transmission. A setting 0 uses the maximum number of hops.
