Situm SDK, by default, only uses beacons with Situm UUID. If you want to use your own beacons, add a custom field with a key called beacons_uuids, and also add the list of beacon identifiers as a value of this key.
Example for one beacon filter:
Example for multiple beacon filters (separated by commas):
To check that they are scanned correctly, in the Positioning menu, the number of WiFi APs and BLE beacons scanned is updated in real-time (1). By clicking on the dialog, you may see all the BLE beacon (2). In Layout you can see the number of uuidd if the beacon isn´t of Situm.
On certain corporate buildings, routers can emit on different MAC addresses, where the last hexadecimal digit changes. If this happens, it is necessary to activate the WiFi enterprise mode, in order to guarantee accurate location information. In order to activate this mode, it is necessary to create a custom field with a key called wifi_virtual_mac_support and a value of true.
Deactivate the GPS Indoor Mode (Calibrated & Uncalibrated) #
Both methods can be deactivated by setting the following custom-field at the building level: use_gps = False. This will cause Situm to not use GPS at all (regardless of how the app is configured).
Allows you to enable/disable the Wifi / BLE classifier for a building. It is used to give a better positioning in the change of plants with the SDK. These are true by default, if floor changes do not work properly, disabling them may improve transitions.
To add a custom Geofence field we go to Cartography-> Geofences:
When we click on Other fields, the button will appear , the key and value options will appear to insert the custom field:
It allows modifying the positioning behaviour by indicating to the Real-Time Locating System that it should apply different behaviours in the area defined by the fence. Important: To apply the changes it is necessary to force the retraining of the model:
Activating the Uncalibrated Indoor Geolocation Mode#
This method is used in 90% of the buildings. It can also be called enhanced GPS because, in addition to the GPS signal provided by Google, it adds the phone’s sensors, which provides greater accuracy.
To activate it go to the dashboard and you can add configuration fences for a building.
To do this, a fence must be created in the area/plant in which you want to use that configuration parameter, with a custom field, whose key is trainer_metadata and a valid JSON value with the desired configuration parameter.
Generally used with “passable” to use GPS in uncalibrated areas. If the GPS gives the position in this area it reduces the confidence in the Wi-Fi.
Refers to the weight factor or weighting factor that is assigned to different elements or variables in a positioning algorithm. This factor determines the relative importance of each element or variable in the final position calculation.
When positioning, a variety of signals or information are used to determine the location of an object or device. These signals may include GPS signal strength, time measurements, radio signals, and other relevant data. Each of these signals or data may have a different accuracy or reliability.
The weight factor is used to assign a weight to each signal or data based on its accuracy or reliability.
max_stay_time: Configuration of the maximum time (in seconds) that a user can spend inside a geofence before triggering the alarm.
time_outside_limit: Following the request to be able to also parameterize the time to leave the geofence before resetting the counter we have created this parameter. That is, setting the maximum time (in seconds) that a user can leave the geofence before closing the session.
The following configuration has been used mostly in COVID times and for enclosures where you want to control the number of people inside:
When a user tries to access the configuration section of the MRM Tracker, the system will ask them to enter a PIN to access. For this to happen we will put in Key pin_config and in Value the numerical value.
When you try to enter the configuration of the App, the following screen will appear:
