The sensor status bar in ArcGIS IPS Setup is located at the top of every open map and indicates the status of your survey device's sensors. Use the Sensor Check menu to verify IPS Setup app permissions and the status of your survey device's Bluetooth, location, compass, gyroscope, and accelerometer sensors. To open the Sensor Check menu, tap the Sensor check bar in any open map.
Verify app permissions
Verify app permissions by completing the following:
- Tap the Sensor check status bar.
The Sensor Check menu appears.
- Ensure that the following permissions are enabled for ArcGIS IPS Setup:
- Google Location Accuracy
- Compass Calibration
When a surveyor is not familiar with a facility, turn on Show GPS location to enable the GPS location in Map mode. You can also show GPS location in Plan mode until the first survey point is entered of the survey. When available indoors, GPS location can help determine a surveyor's approximate location before planning and surveying.
Verify compass accuracy
Use your survey device's compass to determine its heading. Compass accuracy is the deviation between the reported heading and the true geomagnetic heading.
Due to hardware variations among Android devices, the compass does not always satisfy the optimal performance requirements. Compass accuracy can register as one of four states:
- High—If compass accuracy is high, the status is displayed as OK in green.
- Medium—If compass accuracy is moderate, the status is displayed as Medium in orange.
- Low—If compass accuracy is low, the status is displayed as Low in yellow.
- Unreliable—If compass accuracy is poor, the status is displayed as Calibrate in red.
If compass accuracy is high, medium, or low, you can perform a survey. If compass accuracy is unreliable, calibrate the compass before conducting a survey.
To calibrate the compass of your device, complete the following steps:
- Open IPS Setup and sign in if necessary.
- Choose a map from the list of available web maps and tap the map name to open it.
Only maps shared with your organizational account as editable web maps are available in IPS Setup.
- Tap the Sensor check bar.
The Sensor Check menu appears.
- If compass accuracy is unreliable, calibrate the compass by moving the phone in a figure eight shape.
If the compass accuracy is high, medium, or low, no calibration is necessary.
- Swipe down on the screen to refresh the sensor check and confirm calibration.
You can calibrate the compass at any time; it is not necessary to open the Sensor Check menu.
If your survey device is not equipped with a compass or gyroscope, it may not meet sensor calibration requirements. If this is the case, switch to a device that is equipped with these sensors to successfully collect the necessary data.
Configure Wi-Fi scan throttling
IPS Setup includes support for Wi-Fi as well as BLE. You can configure which data type to use for a survey in IPS Setup in the Sensor Check menu of the app.
The IPS Setup app supports the Wi-Fi recorder data type on Android 10 and higher.
After selecting Wi-Fi, the Wi-Fi Scanning Throttling option appears in the Sensors section. Wi-Fi throttling is enabled by default on Android devices. This means that each foreground app can scan four times in a two-minute period, allowing for a burst of scans in a short time, and background apps can scan once in a 30-minute period.
To record Wi-Fi sensor data, you must disable Wi-Fi scanning throttling.
To disable Wi-Fi scan throttling, complete the following steps:
- Enable developer options on your Android device.
Once enabled, Developer options appear in the device's Settings app.
- Choose Developer options and turn off Wi-Fi scan throttling .
- Return to the IPS Setup app and ensure that Wi-Fi Scanning Throttling is disabled.
