OIC Sensor SupportΒΆ

The sensor framework provides support for an OIC enabled application to host the sensor devices as OIC resources. The sensor framework provides the following OIC support:

  • Creates OIC resources for each sensor device that is enabled in the application. It creates an OIC discoverable and observable resource for each sensor type that the sensor device is configured for.
  • Processes CoAP GET requests for the sensor OIC resources. It reads the sensor data samples, encodes the data, and sends back a response.

The sensor package (hw/sensor) defines the following syscfg settings for OIC support:

  • SENSOR_OIC: This setting specifies whether to enable sensor OIC server support. The setting is enabled by default. The sensor package includes the net/oic package for the OIC support when this setting is enabled. The OC_SERVER syscfg setting that specifies whether to enable OIC server support in the net/oic package must also be enabled.
  • SENSOR_OIC_OBS_RATE: Sets the OIC server observation rate.

An application defines an OIC application initialization handler that sets up the OIC resources it supports and calls the oc_main_init() function to initialize the OC server. The application must call the sensor_oic_init() function from the the OIC application initialization handler. The sensor_oic_init() function creates all the OIC resources for the sensors and registers request callbacks to process CoAP GET requests for the sensor OIC resources.
