ST = 0x7D0 (2 second wake time)
SO = 0x06 (enable extended sleep and wake for ST time)
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.
