Sleep commands
CC 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.
The CC command is only supported when using AT
firmware: 20xx (AT coordinator), 22xx (AT router), 28xx (AT
end device).
CRE 0 - 0xFF 0x2B
(‘+’ ASCII)
1. Node types that support the command: C = Coordinator, R = Router, E = End Device

SM Sleep Mode Sets the sleep mode on the RF module. An XBee
loaded with router firmware can be configured as either a
router (SM set to 0) or an end device (SM > 0). Changing a
device from a router to an end device (or vice versa) forces
the device to leave the network and attempt to join as the
new device type when changes are applied.
RE 0-Sleep disabled (router)
1-Pin sleep enabled
4-Cyclic sleep enabled
5 - Cyclic sleep, pin wake
0 - Router
4 - End
Device
SN 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.
CRE 1 - 0xFFFF 1
SP 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.
CRE 0x20 - 0xAF0 x 10ms
(Quarter second resolution)
0x20
ST 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.
E 1 - 0xFFFE (x 1ms) 0x1388 (5
seconds)
SO
Command
Sleep Options. Configure options for sleep. Unused option
bits should be set to 0. Sleep options include:
0x02 - Always wake for ST time
0x04 - Sleep entire SN * SP time
0x06 - Enabled extended sleep and wake for ST time
Sleep options should not be used for most applications. See
Network commissioning and diagnostics on page 82 for
more information.
