| <h1>Changing the Default Configuration for a Sensor<a class="headerlink" href="#changing-the-default-configuration-for-a-sensor" title="Permalink to this headline">¶</a></h1> |
| <p>This tutorial shows you how to change default configuration values for |
| an off-board sensor. It continues with the example in the <a class="reference internal" href="sensor_nrf52_bno055.html"><span class="doc">Enabling an |
| Off-Board Sensor in an Existing Application tutorial</span></a></p> |
| <p><strong>Note:</strong> You can also follow most of the instructions in this |
| tutorial to change the default configuration for an onboard sensor. The |
| difference is that the BSP, instead of the sensor creator package, |
| creates and configures the onboard sensor devices in the <code class="docutils literal notranslate"><span class="pre">hal_bsp.c</span></code> |
| file. You should check the BSP to determine whether the default |
| configuration for a sensor meets your application requirements.</p> |

| <p>The sensor creator package, <code class="docutils literal notranslate"><span class="pre">hw/sensor/creator</span></code>, creates, for each |
| enabled sensor, an os device in the kernel for the sensor and |
| initializes the sensor with its default configuration when the package |
| is initialized. The steps to configure a sensor device are:</p> |
| <ol class="arabic simple"> |
| <li><p>Open the os device for the sensor.</p></li> |
| <li><p>Initialize the sensor driver configuration data structure with |
| default values.</p></li> |
| <li><p>Call the <code class="docutils literal notranslate"><span class="pre"><sensorname>_config()</span></code> function that the sensor device |
| driver package exports.</p></li> |
| <li><p>Close the os device for the sensor.</p></li> |
| </ol> |
| <p>For the BNO055 sensor device, the creator package calls the local |
| <code class="docutils literal notranslate"><span class="pre">config_bno055_sensor()</span></code> function to configure the sensor. A code |
| excerpt for this function is shown below:</p> |
