Endpoint

Zigbee supports multiple endpoints. An endpoint can be a separate application running on each node. Practically speaking, most deployments there is only one endpoint used, but this information is presented in case you wish to use additional endpoints.

Endpoint can be compared to a Socket on the same network(PAN). Endpoints:
 * use 8-bits addressing, up to a maximum of 240 endpoints
 * Each endpoint is addressed by the Endpoint number (1-240) when sending a message
 * One Application Profile described per Endpoint.
 * Endpoint 0 is reserved to describe the generic device capabilities
 * Endpoint 255 is reserved for broadcasting to all endpoints
 * Endpoints 241-254 are reserved for future use
