YAML key: coap_server

Expose CoAP resources over UDP and map requests onto SPX attributes using resource/binding definitions.

Minimal configuration

attributes:
  temperature: 23.5
  setpoint: 18.0

communication:
  - coap_server:
      host: 127.0.0.1
      port: 5683
      default_payload_codec: json
      resources:
        - name: process
          path: [process]
          bindings:
            - name: temperature_get
              method: get
              direction: outbound
              read_attribute: "#attr(temperature)"
              payload_codec: json
              path: [temperature]
            - name: setpoint_put
              method: put
              direction: inbound
              write_attribute: "#attr(setpoint)"
              payload_codec: json
              path: [setpoint]

Notes

• Dependency: requires aiocoap (tests are skipped when it is missing).

• Bindings support get, put, and observe.
