This article shows how to detect the presence of objects in your cells using Location Engine Configuration.
You should know the information in the following article:
Before you start, remember to:
Make sure you have a valid dataset with the "UPresence" module installed.
Start the Location Engine Configuration tool and check that the "Presence" tab is shown.
The Presence module allows you to detect whether tags are present in cells. The module manages presence data that can be inferred from detection of tag radio messages at individual sensors. The tag radio messages are either uplinks or chirps.
In the sensor properties dialog box "Flags" tab, check the "Forward uplinks" box:
In the sensor properties dialog box "User" tab, set a suitable RSSI threshold above which uplinks will be forwarded.
The sensor is now shown in the presence tab:
Chirp forwarding only works for a slave sensor. You will need to reboot the sensor
after setting the "forward chirps" flag.
In the sensor properties dialog box "Flags" tab, check the "Forward chirps" box:
The sensor is now shown in the presence tab:
Reboot the sensor.
You can use the
example program
to view presence data. The lists will be populated with the state of the schema relations at any time.
You will need to have one or more tags present in your site to see entries in the tables.
In the example program, you can choose the location cell for which association data is shown
using the combo box.
Tags present appear in the "Association" list along with any objects whose locations
are driven by those tags.
Only objects in the list will be affected by location injection policies.
See How to set/remove an object ownership in Location Engine Configuration for details on setting object ownerships.
