| 19 | <h1>Sensor View Help</h1> | ||
| 20 | <p>When the view is started a <b>Service Discovery</b> is initiated. On <b>Service Discovery</b> completion (may take a few seconds), | ||
| 21 | sensor images appear and data is displayed next to them. The <b>Preferences</b> tab in the options menu can be used to select <i>which</i> sensors | ||
| 22 | to show. Note that a maximum of four sensors may be activated per connection instance due to a limitation in Android's Bluetooth low energy stack on the number of | ||
| 23 | notifications.</p> | ||
| 24 | <p>Note that magnetometer, gyroscope and height measurement (barometer) are calibrated by tapping on the respective entry in the sensor list. The measured height shown | ||
| 25 | is calculated based on the difference in air pressure between the current measurement and the pressure at the moment of calibration. Measurements are always calibrated | ||
| 26 | on connection (but may be re-calibrated any time).</p> | ||
| 27 | <p>The SensorTag firmware can be upgraded OTA (Over The Air) via <b>Firmware Update</b> in the Options Menu. The application will contain images for the latest firmware, | ||
| 28 | but it is also possible to download custom images from Android's 'Download' directory. There are | ||
| 29 | two FW images for each FW revision. These are labeled <q>A</q> and <q>B</q> and differ only by the destination address in the | ||
| 30 | SensorTag flash. Alternative images must always be used; if the current image in flash is of type <q>A</q> the new one must of type | ||
| 31 | <q>B</q> and vice versa.<hr /> | ||
