6.4.5 Finding and Binding

The user can configure the target endpoint/initiator endpoint as the following:
  • Zigbee end device/multisensor – As the initiator endpoint
  • Zigbee coordinator/combined interface – As the target endpoint

The following figure illustrates packets #416 and #419 as Identify Query Request and Identify Query Response from the end device and coordinator devices, respectively.

The end device as an initiator broadcasts Identify Query for identifying target endpoints. After receiving 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 and 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 Identify Query Response, that is, identifying the target endpoint, the target endpoint requests the Simple Descriptor.

Packets #425 and #430 are Simple Descriptor Request and Simple Descriptor Response from end device and coordinator devices, respectively.
