Name and Description
Command Sequence Character. Set/Read the ASCII character value to be used
between Guard Times of the AT Command Mode Sequence (GT + CC + GT). The AT
Command Mode Sequence enters the RF module into AT Command Mode.
CC command is only applicable when using modules that contain the following “AT
Command” firmware versions: 8.0xx (Coordinator), 8.2xx (Router), 8.4xx (End Device)
Name and Description
Sleep Mode Sets the sleep mode on the RF module
Number of Sleep Periods. Sets the number of sleep periods to not assert the On/Sleep
pin on wakeup if no RF data is waiting for the end device. This command allows a host
application to sleep for an extended time if no RF data is present
Sleep Period. This value determines how long the end device will sleep at a time, up to
28 seconds. (The sleep time can effectively be extended past 28 seconds using the SN
command.) On the parent, this value determines how long the parent will buffer a
message for the sleeping end device. It should be set at least equal to the longest SP
time of any child end device.
Time Before Sleep Sets the time before sleep timer on an end device.The timer is reset
each time serial or RF data is received. Once the timer expires, an end device may enter
low power operation. Applicable for cyclic sleep end devices only.

Note: When SM=0, the
device operates as a
router. When SM
changes to a non-zero
value, the router leaves
the network and rejoins
as an end device. Only
end devices can sleep
