6.3.4 Finding and Binding
- Zigbee router/extended lights – As the initiator endpoint
- Zigbee coordinator/combined interface – As the target endpoint
The following figure illustrates packets #47 and #48 as
the Identify Query Request and Identify Query Response
from router and coordinator devices, respectively.
The router, as an initiator, broadcasts Identify Query for identifying
target endpoints. After receiving the Identify Query Response from a
target endpoint, the initiator unicasts the Simple Descriptor Request
to the target device. The initiator endpoint, then, searches for any matching clusters
between itself and the target endpoint; then, for each match found, it creates a
corresponding entry in its binding table. If there is a request for group binding, the
initiator endpoint configures group membership of the target endpoint.
After receiving the Identify Query Response, the router identifies the
target endpoint and requests the Simple Descriptor. Packets
#53 and #55 are Simple Descriptor
Request and Simple Descriptor Response from the router and
coordinator devices, respectively.
