Managing End Devices Sleep examples
XBee/XBee-PRO ZigBee RF Modules User Guide 101
For best results, the end device should send a transmission when it wakes to inform the coordinator
(or network) when it wakes. It should also remain awake for a short time to allow devices to send
data to it. The following are recommended settings.
ST = 0x7D0 (2 second wake time)
SO = 0x06 (enable extended sleep and wake for ST time)
IR = 0x800 (send 1 IO sample after waking). At least one analog or digital IO sample should be
enabled for IO sampling.
With these settings, the end device will wake after 4 minutes and send 1 IO sample. It will then
remain awake for 2 seconds before returning to sleep.
SP and SN should be set to the same values on all routers and coordinators that could allow the end
device to join. This will ensure the parent does not timeout the end device from its child table too
quickly.
The SI command can optionally be sent to the end device to cause it to sleep before the sleep timer
expires.
