| <h1>OIC Sensor Support<a class="headerlink" href="#oic-sensor-support" title="Permalink to this headline">ΒΆ</a></h1> |
| <p>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:</p> |
| <ul class="simple"> |
| <li><p>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.</p></li> |
| <li><p>Processes CoAP GET requests for the sensor OIC resources. It reads |
| the sensor data samples, encodes the data, and sends back a response.</p></li> |
| </ul> |
| <p>The sensor package (<code class="docutils literal notranslate"><span class="pre">hw/sensor</span></code>) defines the following syscfg settings |
| for OIC support:</p> |
| <ul class="simple"> |
| <li><p><code class="docutils literal notranslate"><span class="pre">SENSOR_OIC</span></code>: This setting specifies whether to enable sensor OIC |
| server support. The setting is enabled by default. The sensor package |
| includes the <code class="docutils literal notranslate"><span class="pre">net/oic</span></code> package for the OIC support when this |
| setting is enabled. The <code class="docutils literal notranslate"><span class="pre">OC_SERVER</span></code> syscfg setting that specifies |
| whether to enable OIC server support in the <code class="docutils literal notranslate"><span class="pre">net/oic</span></code> package must |
| also be enabled.</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">SENSOR_OIC_OBS_RATE</span></code>: Sets the OIC server observation rate.</p></li> |
| </ul> |
| <p>An application defines an OIC application initialization handler that |
| sets up the OIC resources it supports and calls the <code class="docutils literal notranslate"><span class="pre">oc_main_init()</span></code> |
| function to initialize the OC server. The application must call the |
| <code class="docutils literal notranslate"><span class="pre">sensor_oic_init()</span></code> function from the the OIC application |
| initialization handler. The <code class="docutils literal notranslate"><span class="pre">sensor_oic_init()</span></code> function creates all |
| the OIC resources for the sensors and registers request callbacks to |
| process CoAP GET requests for the sensor OIC resources.</p> |
| <p>See the <a class="reference internal" href="../../../tutorials/sensors/sensor_oic_overview.html"><span class="doc">Enabling OIC Sensor Data Monitoring |
| Tutorials</span></a> to run and |
| develop sample OIC sensor server applications.</p> |
