The following cluster IDs are supported on the data endpoint (0xE8):

XBee ZNet 2.5 modules support sleep mode operation in the Router / End Device firmware. Sleep
modes allow a ZigBee end device to enter a low power mode when idle and wake as needed to
transmit or receive data.
End devices must join to a router or coordinator to become part of a network. When the join
occurs, the end device becomes the child of the router or coordinator that allowed the join, and
the device that allowed the join becomes the end device’s parent.
A router or coordinator can only allow up to 8 end devices to join to it. Once 8 end devices have
joined to a parent, no additional end devices can join until a network reset condition occurs on the
parent.
ZigBee end devices rely on a parent (router or coordinator) to remain awake and receive any data
packets destined for the end device. When the end device wakes from sleep, it sends a
transmission (poll request) to its parent asking if the parent has received any RF data destined for
the end device. The parent, upon receipt of the poll request, will send an RF response and the
buffered data (if present).
If the parent has no data for the end device, the end device may return to sleep, depending on its
sleep mode configuration settings. The following figure demonstrates how the end device uses
polling to receive RF data through its parent.
