Configure XBee radio settings
66
Advanced radio settings control behavior of the XBee Module at a
more detailed level. Generally, these settings can be left at their
defaults.
• Transmit Power Level: Sets the power level at which the XBee
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. 0 sets the radio to use the maximum
number of hops.
Serial interface settings
• Baud Rate: The baud rate for the modem serial port.
• Parity: The parity for the modem serial port.
• Flow Control: Enable or disable CTS flow control for the serial port.
• Packetization Timeout: The number of character times of inter-
character delay required before transmission. If set to zero,
characters are transmitted as soon as they arrive instead of
buffering them into one RF packet.
