Bluetooth Tag Settings
The Enlighted tags broadcast Bluetooth Low Energy (BLE) beacon messages to Enlighted sensors that forward the messages to Manage. The Where application uses the data from Manage to track tags as they move through the building. The real-time and historic location data can be used to find assets in real-time, provide space utilization analytics, or notify a specific user when certain event conditions are met. Where’s powerful event monitoring features detect conditions configured in the application and trigger events. The tags generate events that are sent to the sensors, which then forward the messages to Manage. The tags send the following types of tag event messages:
- Tag button events when the button is activated on the physical tag
- Low battery alert events
Due to the volume of data collected by the sensors and reported to Manage, it may sometimes lead to heavy traffic load, packet loss, and network congestion. To reduce congestion in the network, you can configure the Bluetooth Tag Settings in Manage by
Choosing a Data Reporting Interval
The sensors report tag events to Manage every 30 seconds and battery events every 240 seconds by default. The system or facility admin may change the default values for all sensors in the building to reduce network congestion, packet loss, or delays. To control the frequency of how often the sensors report tag messages to Manage,
- Navigate to the Settings tab.
- Select a building in the left-panel facility tree.
- In the Bluetooth Tag Settings box,
- Specify a time interval in seconds (between 1-255 seconds) for how often the sensors report tag button events.
- Specify a time interval in seconds (between 60-255 seconds) for how often the sensors report battery events.
- Click Save.
Selecting Sensors to Report Data
Sensors, by default, are not listening for BLE tag events. You must manually select sensors on the floor plan to receive BLE tag messages from tags. To choose which sensors can receive and report BLE tag messages to Manage,
- In the Facilities left-panel, click on the floor name. On the floor plan display.
- Select the Floor Plan tab.
- Select Bluetooth mode from the View drop-down list.
- Select one or more sensors on the floor plan and right-click to display a dialog box.
- Select Start Tag Events. The message Event Started Successfully is displayed, confirming that the sensors are forwarding tag events to Manage.
To stop sending messages anytime, repeat the above process, and select Stop Tag Events. The message Event Stopped Successfully is displayed, confirming that the sensors are not reporting messages from the tags to Manage.
Verifying the BLE Tag Event Status for a Sensor
You can verify if a sensor is reporting tag events to Manage from the Fixture Details screen.
- Double-click the sensor on the floor plan to view the Fixture Details screen. If the sensor is reporting tag events, the BLE Tag Events Status will be displayed as Enabled. Disabled means the sensor is not reporting tag events. See Selecting Sensors to Report Data to start or stop tag events. By default, sensors do not report tag events, and they must be configured to report tag events after upgrading to the Manage 4.0 release.
The Where application location accuracy depends on the distance of the beacon signals from the tags to the sensors mounted on the ceiling or anchored to a fixture. Several critical factors such as the floor height, floor elevation, sensor height offset from the ceiling, and type of fixture installation determine the accurate location of objects or people on a floor. All these have to be configured in Manage for the Where application to locate objects or people precisely on the floor. Note that these fields are only used by the Where application and are optional for other applications. Before entering the following information in Manage, verify the existing elevations on a site with the available civil drawings.
Ceiling Height – This is the ceiling height, above the finished floor, of each floor in the building. Typical ceiling heights in commercial office buildings is 10-12 feet. If the ceiling height is not specified, the Where application uses a default height of 12 feet. Valid values range from 0 to 100 feet and values must be entered in feet (e.g. 12’ 3” = 12.25).
Floor Elevation – This is the vertical distance above or below the Ground Floor. In North America, the first floor is considered the Ground Floor and would have a Floor Elevation of 0. The second-floor elevation could be 20 feet above the Ground Floor, the third floor at 40 feet above Ground Floor, and the basement could be negative 20 (-20) feet below the Ground Floor. Valid values range from -1000 to 10,000 feet and values must be entered in feet (e.g. 75’ 6” = 75.5).
Ceiling Height Offset – The difference between the ceiling height and the height of the sensor, relative to the finished floor. For example, a pendant fixture hanging 3 feet below the ceiling would have a Sensor Height Offset of negative 3 (-3). If no value is entered the offset is assumed to be zero feet. A lobby entrance with a 5-foot taller ceiling than the waiting area would have a Sensor Height Offset value of positive 5 feet.
Note: The offset value must not be above or lower than the ceiling height. For example, if the ceiling height is 12 feet, the height offset value from the ceiling cannot be greater than +12 or lower than -12 feet. Values must be entered in feet (e.g. 1’ 2” = 1.17).
Ceiling Height and Floor Elevation
Only the system or facility admin may update the ceiling height and floor elevation information for the building or add new floors. To edit the floor height and elevation for a building,
- Select a facility in the facility's navigation panel.
- Select a campus and building.
- Click the Settings tab.
- Scroll to the Details panel.
- Select a Floor Name from the list of floors and click the Edit button.
- Type a value for Ceiling Height in feet.
- Type a value for Floor Elevation in feet of the floor.
- Click Save.
Ceiling Height Offset
The sensor height offset can be set for individual sensors from the floor plan. In the Facilities left panel, click on the floor name. On the floor plan display, double-click a sensor to open the Fixture Details dialog box. Edit the Ceiling Height Offset value for the sensor and click the Apply button to save the setting.
Fixture Installation Type
The type of sensor installation impacts Where accuracy location since the measurement of the beacon signal varies with distance to the ceiling or fixture-anchored sensor. The Where application uses both fixture and fixtureless sensors. Fixture sensors control lighting, and fixtureless sensors are used for location and positioning services, and hence are connected to fixtures.
The Enlighted sensor can either be integrated into the fixture or mounted external to the fixture. Here are the four most common ways to distinguish a fixture type installation.
- Not Enclosed – The sensor is not connected to the fixture. For example, sensors mounted to the ceiling tile. Refer to the Micro Sensor or High Bay Sensor Install guides.
- Partially Enclosed – The sensor is mounted external to the fixture. For example, sensors mounted external to the fixture without metal backing.
- Fully Enclosed – The sensor is integrated into the fixture. For example, sensors mounted external to the fixture with metal backing.
- Unknown – Sensor Installation Type is not known.
To edit the type of fixture installation details for a fixture, navigate to Administration-> System Management and select the Fixture Type Management tab. Click on the Fixture Type tab. Select a fixture and click Edit to edit the fixture Install Type.
In the Edit Fixture Type window, choose the Install Type from the dropdown list for lighting. Click Save to save the fixture type.
