@situm/cordova-mrm-safety

Situm inertial safety module for Cordova. It provides Tap, Fall and Inactivity detection, designed to work together with active Situm positioning.

Getting Started

This plugin is intended to be integrated into a Cordova Android app together with @situm/cordova. The basic setup is described below.

Running the example

Check the example README to run a complete demo app using this plugin.

Requirements

• Cordova CLI (npm i -g cordova)
• Android platform added to the app (cordova platform add android)
• Android SDK + JDK compatible with your Cordova setup
• Situm Cordova plugin installed in host app: @situm/cordova

Install the plugin in a host Cordova app

Run all commands from your host Cordova app root.

1. Install Situm plugin:

cordova plugin add @situm/cordova

2. Install this plugin (Artifactory-backed dependency resolution):

cordova plugin add @situm/cordova-mrm-safety

3. Build Android:

cordova build android

Minimal usage

Recommended order: start Situm positioning first, then start inertial detectors.

cordova.plugins.Situm.setUserPass(email, password);
cordova.plugins.Situm.requestLocationUpdates({
  buildingIdentifier: "YOUR_BUILDING_ID",
});

window.InertialEvents.onEvent((event) => {
  // event.type: "tap" | "fall" | "inactivity" | "error"
  // event.timestamp: epoch millis
  console.log("Inertial event", event);
});

window.InertialEvents.enableBackground();

window.InertialEvents.startTap({ taps: 3, sensitivity: 8 });
window.InertialEvents.startFall({ sensitivity: 0.5, lieTimeSec: 30 });
window.InertialEvents.startInactivity({
  sensitivity: 0.5,
  idleTimeSec: 30,
  ignoreHorizontal: true,
});

To stop:

window.InertialEvents.stopTap();
window.InertialEvents.stopFall();
window.InertialEvents.stopInactivity();
window.InertialEvents.stopAll();
cordova.plugins.Situm.removeUpdates();

Important behavior

Detectors may be running, but inertial callbacks are emitted only while Situm positioning is running (LocationManager.isRunning() == true).

Background Mode

To continue detecting emergency events even when the app is in the background, the screen is off, or the app has been minimized, you must enable Background Mode.

What does Background Mode do?

This mode starts a Foreground Service of type health.

Foreground Services are designed to perform ongoing operations that the user should be aware of. They display a persistent notification, giving the service higher priority so it can reliably detect emergency events in the background.

Important

This Foreground Service is used exclusively to detect potential emergencies that users may need to report, even when the app is not actively in use.

Permissions added automatically

When you add this plugin, the following permissions will be automatically added to your AndroidManifest.xml:

<uses-permission android:name="android.permission.HIGH_SAMPLING_RATE_SENSORS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_HEALTH" />

You don't need to require in runtime the before mentioned permissions as they are granted at install time.

Enable background inertial detection:

window.InertialEvents.enableBackground();
// then startTap/startFall/startInactivity

Disable background mode:

window.InertialEvents.disableBackground();

Notes:

• Android will show a persistent foreground notification.
• If the app task is removed from recent apps, the service stops.

Troubleshooting

1. No inertial events are received

   • Verify Situm login succeeded and requestLocationUpdates(...) is active.

2. Android permission errors

   • Grant runtime location/BLE permissions.

Versioning

This package is uploaded to npm as @situm/cordova-mrm-safety. To upload a new version, first make sure to update the "version" parameter at the package.json of the plugin so npm detects is a new version. You can update the plugin version by executing the command:

npm version patch # To upgrade the patch number of the version

Then, execute the following commands:

npm login # Login with the mobile account
npm pack --dry-run # To check out what will be pushed before actually uploading a new version
npm publish
