🚧

NEW SDK for Inform Clients!

We are pleased to announce a new Validic Mobile SDK (version 2.x), which will be affectionately known as the Inform Mobile SDK or the Inform SDK since it is available for Inform clients only.

The Inform SDK is now available in a new mobile portal experience called Artifactory.

If you’re interested in learning more about this new SDK please review the details in our Release Notes and then reach out to our Validic Support team to get access.

This project integrates Healthkit, Google Fit, and Samsung Health with the Validic Mobile Aggregator to passively collect data on behalf of an end user.

Are you already using our React Native wrapper? If so, are you interested in accessing our React Native Bluetooth framework? Reach out to our customer support team or your Validic Client Success Executive if you'd like to learn more about our Bluetooth support for React Native!

Requirements

This plugin provides a bridge between a React Native based application and native Validic Mobile libraries. The native libraries are required for use of this plugin.

Plugin requirements:

• React Native 0.62.3 and above.
• Specific supported phones, peripherals, and/or operating system versions are documented as part of the native libraries.

Prerequisites

In order to use the Validic Mobile Library, you will need a valid organization id and valid user credentials.

If you do not already have an organization id, you will need to first apply for one.

After your organization is set up, you will need a Validic user id and access token.

Validic user can be provisioned using the Validic API, documentation is available for both Legacy API (V1) and Inform API (V2) APIs. The credentials needed are a Validic user ID, an organization ID and a user access token. The user access token value you provide to the SDK is the "user access token" value if you use the Legacy (V1) API. The user access token value you provide to the SDK is the "mobile token" value if you use the Inform (V2) API.

Add Plugin to React Native Project

Install

To get started, download the React Native framework from the Validic Mobile portal. Install the framework:

$ npm install <path to react-native-validic-session-1.4.5.tgz> --save

or use yarn

$ yarn add <path to react-native-validic-session-1.4.5.tgz>

Link framework

Automatic

react-native link <path to react-native-validic-session-1.4.5.tgz>

For iOS users using Pods
You still need to run pod install after running the above link command inside your IOS folder.

Manual

pod 'React', :path => '../node_modules/react-native'

pod 'RNValidicSession', :path= => '../node_modules/react-native-validic-session'

Import

import ValidicSession from '<path to react-native-validic-session-1.4.5.tgz>';

Session

Record types

The Validic Mobile library supports the following record types:

• Biometrics - comprised of a user’s biometric health data such as blood pressure, cholesterol, heart rate, and blood and hormone levels.

• Diabetes - comprised of a user’s blood glucose and hormone levels related to diabetes treatment and management.

• Fitness - comprised of a user’s activities that are undertaken with the express purpose of exercising. These activities have a defined duration (time, distance, elevation, etc.)

• Nutrition - comprised of a user’s activities related to calorie intake and consumption and nutritional information (such as fat, protein, carbohydrates, sodium, etc.)

• Routine - comprised of a user’s activities that occur regularly throughout the day, without the specific goal of exercise, for example calories burned and consumed, steps taken, stairs climbed. These activities are aggregated throughout the day.

• Sleep - comprised of a user’s measurements related to the length of time spent in various sleep cycles, as well as number of times awakened during the night.

• Weight - comprised of a user’s weight and body mass.

Record Identifiers

The Validic Mobile SDK uses log_id (for the Inform/V2 API) or activity_id (for the Legacy/V1 API) as the unique identifier for a given record. These IDs are created by the mobile SDK before submission to the server.

The Validic server also assigns an id (for the Inform/V2 API) or _id (for the Legacy/V1 API) for each unique record. It is recommended to use the server-side id / _id to identify and/or de-duplicate records post-submission.

Provision a user

The Validic Mobile library requires a Validic user. A Validic user can be provisioned using the Validic API. The library requires a Validic user ID, user access token and organization ID. It is recommended to provision the user on your server, the mobile app could then authenticate to the server and retrieve the Validic credentials.

Manage a session

The ValidicSession persists a user across the sdk and all pending record uploads. This data is persisted between
app launches but is deleted if the ValidicSession.endSession function is called.

A new Session is started by passing previously provisioned Validic user credentials to the startSession function.

ValidicSession.startSession({user_id:USER_ID, org_id: ORGANIZATION_ID, user_token: USER_ACCESS_TOKEN});

The supplied credentials are validated when the session is created. Records will fail to upload if invalid credentials have been provided. Credentials are stored persistently. To change credentials, call:

ValidicSession.endSession();

or uninstall the app. When a new session is created, pending record uploads and subscriptions are reset. For this reason, a new session should only be created if a session it not already active.

The app can be informed of record upload success and failure by registering callbacks using:

Handle events

Listeners can be added to listen for success or failure of records submitted to the Validic Api. Registration of listeners is typically done during component initialization to catch events for record uploads which may occur upon app restart.

ValidicSession.eventEmitter.addListener('validic:session:onsuccess', (record)=>{
	// the record was successfully uploaded to validic servers
	console.log("Successfully got record" + JSON.stringify(record));
});
ValidicSession.eventEmitter.addListener('validic:session:onerror', (error, record)=>{
	// an error was returned while submitting the record
	console.error("Got error: "+error + " for record: " + record.activity_id);
});

Example

The following example starts a session if a session is not already active and registers session listeners.

componentDidMount(){
ValidicSession.eventEmitter.addListener('validic:session:onsuccess', (record)=>{
	// the record was successfully uploaded to validic servers
	console.log("Successfully got record" + JSON.stringify(record));
});
ValidicSession.eventEmitter.addListener('validic:session:onerror', (error, record)=>{
	// an error was returned while submitting the record
	console.error("Got error: "+error + " for record: " + record.activity_id);
});

var user = {
    user_id: "replace with userid",
    user_token : "replace with access token",
    org_id : "replace with organization id"
};
// check if a persistent user already exists 
ValidicSession.getUser((response)=>{
	//if not, start a new session
	if(response.user == null){
		ValidicSession.startSession(user);
	}
});
}

...
//remove event listeners when the component is going to be unmounted 
componentWillUnmount(){
	ValidicSession.eventEmitter.removeAllListeners('validic:session:onsuccess');
	ValidicSession.eventEmitter.removeAllListeners('validic:session:onerror');
}

Logging

Logging for the Native sdk can be enabled or disabled at runtime.

import {ValidicLog} from 'react-native-validic-session';
// to enable
ValidicLog.enable();
// to disable
ValidicLog.disable();

Healthkit

This project integrates Healthkit with the Validic Mobile Aggregator to passively collect Apple Health data on behalf of an end user.

Install

To get started, first install the framework

$ npm install react-native-validic-aggregator-ios --save`

or use yarn

$ yarn add react-native-validic-aggregator-ios`

Link framework

Automatic

react-native link react-native-validic-aggregator-ios

For iOS users using Pods
You still need to run pod install after running the above link command inside your IOS folder.

Manual

pod 'React', :path => '../node_modules/react-native'

pod 'RNValidicHealthkit', :path => '../node_modules/react-native-validic-aggregator-ios'
pod 'RNValidicSession', :path= => '../node_modules/react-native-validic-session'

Enable Healthkit

To enable use of HealthKit in the app, within the build settings of your target, select the 'Signing & Capabilities' tab and click '+ Capability'. Choose 'HealthKit' and make sure 'Background Delivery' is checked as well.

If Healthkit is not enabled, an error is reported in the console log on app launch but will not report an error during build.

Permission Usage Descriptions

Usage descriptions have to be declared in project's Info.plist for permissions of the Camera, Bluetooth and to access and update Healthkit data.

• HEALTH_SHARE_USAGE_DESCRIPTION for NSHealthShareUsageDescription
• HEALTH_UPDATE_USAGE_DESCRIPTION for NSHealthUpdateUsageDescription

Usage

import { ValidicHealthKit } from 'react-native-validic-aggregator-ios';

Checking if HealthKit is available

Not all iOS devices support HealthKit (e.g. iPads running iOS 16 or lower and other platforms such as Android). To check if HealthKit is available, Apple provides an API: [HKHealthStore isHealthDataAvailable]. For convenience, Validic provides a React Native method to check this value: ValidicHealthKit.isHealthDataAvailable(). It returns a Promise that resolves to the value returned [HKHealthStore isHealthDataAvailable] and false for every other platform.

ValidicHealthKit.isHealthDataAvailable()
  .then(healthDataIsAvailable => {
    if (healthDataIsAvailable) {
      console.log('HealthKit is available!');
    }
    else {
      console.log('HealthKit is not available :(');
    }
  });

// async/await
try {
  const available = await ValidicHealthKit.isHealthDataAvailable();
  console.log("HealthKit is available:" + available);
} catch(error) {
  console.error(error);
}

Subscriptions

To subscribe to HealthKit sample types:

Current Subscriptions

To retrieve the list of Sample Types currently being observed

ValidicHealthKit.getCurrentSubscriptions()
  .then(subscriptions => {
    console.log(JSON.strigify(subscriptions)); // ["HKQuantityTypeIdentifierStepCount"]
  })
  .catch(error => console.error(error));

// async/await
try {
  const subscriptions = await ValidicHealthKit.getCurrentSubscriptions();
  console.log(JSON.stringify(subscriptions)); // ["HKQuantityTypeIdentifierStepCount"]
} catch (e) {
  console.error(e);
}

Set Subscriptions

Calling ValidicHealthKit.setSubscriptions(subscriptions) will replace any existing subscriptions, so it is important to always pass all of the subscriptions desired each time the method is called. The function accepts an array of strings mapping to HealthKit sample type identifiers (e.g. "HKQuantityTypeIdentifierStepCount") and returns a Promise that resolves after permissions have been granted by the end user and the subscriptions have been set up.

To get a list of the currently subscribed data types use the method described in Current subscriptions

ValidicHealthKit.setSubscriptions([ValidicHealthKit.SampleTypes.HKQuantityTypeIdentifierStepCount])
  .then(() => {
    console.log("Subscribed to Steps");
  })
  .catch(error => console.error(error));

// async/await
try{
  await ValidicHealthKit.setSubscriptions([ValidicHealthKit.SampleTypes.HKQuantityTypeIdentifierStepCount]);
  console.log("Subscribed to steps");
} catch (e) {
  console.error(e);
}

Fetching historical data

To fetch historical Summary data use the fetchHistory function. The maximum amount of data that can be fetched is 180 days in the past.

  let start = new Date()
  let end = new Date()
  start.setDate(end.getDate()-29)
  ValidicHealthKit.fetchHistory({
    historicalSets: [ValidicHealthKit.HistoricalSets.HistoricalSetRoutine],
    from: start.toISOString(),
    to: end.toISOString()
  })
  .then(summary => {
    console.log(JSON.stringify(summary));
  })
  .catch(error => {
    console.error(error);
  });

  // async/await
  try {
    const summary = await ValidicHealthKit.fetchHistory({
      historicalSets: [ValidicHealthKit.HistoricalSets.HistoricalSetRoutine],
      from: start.toISOString(),
      to: end.toISOString()
    });
    console.log(JSON.stringify(summary));
  } catch (e) {
    console.error(e);
  }

Events

An event will be passed to ValidicHealthKitEvents every time HealthKit processes new records. The event contains a summary of the number of records collected per SummaryType.

ValidicHealthKitEvents.addListener('validic:healthkit:onrecords', (summary) => {
    console.log(JSON.stringify(summary)); // {"biometrics":1, "summary":1}
});

Listeners should be removed as soon as they are no longer needed, or when the component observing them will be unmounted.

componentWillUnmount() {
    ValidicHealthKitEvents.removeAllListeners('validic:healthkit:onrecords');
}

Google Fit

❗️

Google Fit SDKs are being sunset by Google

As of May 1, 2024 Google has decided to stop accepting new applications for the Google Fit Android SDKs that are used in the Validic Mobile Google Fit integration.

As of this update, the Fit Android SDKs are deprecated and will be officially sunset on June 30, 2025. You can find the latest information from Google at any time by visiting their help pages.

During this time, clients who have already been approved by Google to use the Google Fit Android SDKs may continue to use the Google Fit integration.

Validic now offers an SDK integration to Android Health Connect, which can be used to retrieve Google Fit data. To learn more, please see Migrating Users from Google Fit SDK to Health Connect.

This project integrates Google Fit with the Validic Mobile Aggregator to passively collect data on behalf of an end user. Validic ensures that our Mobile SDK makes use of the minimal scopes needed for our supported data types. Additionally, when using Google Fit version com.google.android.gms:play-services-fitness:19.0.0 or lower, Validic does not request or use any scopes indicated as sensitive or restricted by Google.

As of Google Fit version com.google.android.gms:play-services-fitness:20.0.0, all read scopes are restricted and require completing Google’s sensitive scope verification or restricted scope verification and security assessment to retrieve data. Please see Google's announcement for further details: https://developers.google.com/fit/improvements

- Install

$ npm install react-native-validic-aggregator-fit --save

- Mostly automatic installation

$ react-native link react-native-validic-aggregator-fit

Import

import ValidicAggregatorFit from 'react-native-validic-aggregator-fit';

Initialization

ValidicAggregatorFit will be initialized at app startup and will immediately start listening for
previously subscribed data types. It is recommended that you set a listener on the ValidicAggregatorFit during your componentDidMount() method

    componentDidMount() {
        ValidicAggregatorFit.eventEmitter.addListener('validic:fit:onrecords',(summary)=>{
            console.log("Proccessed Google Fit Data");
            console.log(summary);
        });
        ValidicAggregatorFit.eventEmitter.addListener('validic:fit:onerror', (callback)=>{
            console.warn(callback.error);
        });

Make sure to unsubscribe from events during componentWillUnmount().

    componentWillUnmount() {
        ValidicAggregatorFit.eventEmitter.removeAllListeners('validic:fit:onrecords');
        ValidicAggregatorFit.eventEmitter.removeAllListeners('validic:fit:onerror');

Request permissions

Before collecting any data from Google Fit, a Google Account must be associated with the ValidicAggregatorFit, and the end user must authorize the app to collect data on their behalf.

Get previously granted permissions

To check if permissions have already been granted the hasDataAccess(dataTypes) method can be used

import { Platform, PermissionsAndroid } from 'react-native';

    let permissions = await ValidicAggregatorFit.requestPermissions([ValidicAggregatorFit.DataTypeStepCount])
    if(permissions[ValidicAggregatorFit.DataTypeStepCount] == true){
        //subscribe
    }

The promise returned from hasDataAccess(dataTypes) associates a DataType with true, if a valid Google account exists and permission has previsouly been granted, or false otherwise.

Request new permissions

To request permission from the end user to authorize data collection the requestPermissions(dataType) function can be used to authorize your application

 let permissions = await ValidicAggregatorFit.requestPermissions([ValidicAggregatorFit.DataTypeStepCount])
 if(permissions[ValidicAggregatorFit.DataTypeStepCount] == true){
     //subscribe
 }

Android 10

For the Android client Apps that target API 29 the permission below is required in the AndroidManifest.xml. The Validic SDK will add this permission to its manifest so that it will be merged with the client when they add our library to their application.

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>

This permission is required to subscribe to the following data types:

• com.google.step_count.delta
• com.google.step_count.cumulative
• com.google.step_count.cadence
• com.google.activity.segment
• com.google.activity.exercise

For apps targeting Android 10, this permission must be requested from the user at runtime

  var granted = await PermissionsAndroid.check(
    'android.permission.ACTIVITY_RECOGNITION',
  )
    if (!granted){
        granted = await PermissionsAndroid.request(
      'android.permission.ACTIVITY_RECOGNITION',
      {
        'title': 'Example App',
        'message': 'Example App access to your location '
      }
    )
    }
    if(!granted){
        console.log("Activity Permission not granted")
    }

Manage subscriptions

After Permissions have been granted for a DataType the ValidicAggregatorFit can be used to add subscriptions to data change events from Google Fit.
Data will automatically will queued for submission to the Validic API when internet is available on the device

    ValidicAggregatorFit.subscribe([ValidicAggregatorFit.DataTypeStepCount]);

To unregister from receiving data update events use the ValidicAggregatorFit to unsubscribe

    ValidicAggregatorFit.unsubscribe(ValidicAggregatorFit.DataTypeStepCount);

Get a list of currently subscribed DataTypes

    let subscriptions = await ValidicAggregatorFit.currentSubscriptions()

Get currently supported DataTypes

Available datatypes can be referenced from the ValidicAggregatorFit.datatype

• DataTypeStepCount
• DataTypeWeight
• DataTypeHeartRate
• DataTypeCaloriesExpended
• DataTypeMoveMinutes
• DataTypeDistance
• DataTypeNutrition

Records collected are automatically submitted to the Validic Inform API and a summary of records processed will be sent as an event named validic:fit:onrecords.

For an example of setting a listener see Initialization

Fetch Historical Summary data

Depending on your use case, it might be beneficial to capture an end-user's Summary data from previous days that has been stored in Google Fit. To fetch up to 180 days of previous summary data for a user use the fetchHistory() function.

ValidicAggregatorFit.fetchHistory

Please note that this is a computationally expensive task that requires fetching data from google. Only a single call to this function can take action and consecutive calls to this method will be dropped until the first call has completed. After all processing has been completed a summary event will be emitted to any listeners registered to the eventEmitter for the validic:fit:onrecords event. If any error occurs, an error event will be emitted to any listeners registerred to the validic:fit:onerror event.

For an example of setting a listener see Initialization

Logout

To remove all subscriptions and log an end user out simply call

    ValidicAggregatorFit.disconnect()

Samsung Health

This project integrates Samsung Health with the Validic Mobile Aggregator to passively collect data on behalf of an end user.

❗️

Approval Required

The Samsung Health integration requires pre-approval for Samsung's Device SDK.

Currently, Samsung is going through an update to better support their partners and, for that reason, they are not accepting applications for the Partner Apps Program.

If you would like to retrieve Samsung Health data, please consider Health Connect. Health Connect serves as a health data aggregator on Android phones -- like Apple Health does for iPhones -- and you will be able to receive Samsung Health data, Google Fit data, and more through our integration to Health Connect.

See Migrating Users from Samsung Health SDK to Health Connect for more information.

Install

To get started, install the framework

$ npm install react-native-validic-aggregator-shealth --save

Mostly automatic installation

$ react-native link react-native-validic-aggregator-shealth

Manual installation

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import com.validic.mobile.rn.shealth.RNValidicMobileAggregatorPackage; to the imports at the top of the file
• Add new RNValidicMobileAggregatorPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-validic-aggregator-shealth'
   project(':react-native-validic-aggregator-shealth').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-validic-aggregator-shealth/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-validic-aggregator-shealth')
   

Samsung Health

In order to use Samsung Health with ValidicMobile a valid copy of the Samsung Health SDK must be provided by the developer. This can be downloaded from the SHealth developer portal: Samsung SHealth Developer.

Place the samsung-health-data-v1.5.0.aar in the same `android/app/libs of your app. If the folder does not exist, please create it

Developer mode

In order to test, you must enable developer mode in the Samsung Health app on your phone. For instructions on how to enable developer mode please see Samsung's website: https://developer.samsung.com/health/android/data/guide/dev-mode.html

Note: Starting with Samsung Health app version 6.11.0.061 (released August 2020), in order to gain access to Samsung Health data, with or without developer mode enabled, you must first be approved by Samsung and receive a Samsung dev access key. Prior versions of the Samsung Health app do not require the dev access key when the Samsung Health app is in developer mode.

You can learn more about requesting access via Samsung's website here: https://developer.samsung.com/health/android/overview.html#Partner-Apps-Program

Import

import ValidicSHealth from 'react-native-validic-aggregator-shealth';

Manage subscriptions

Configuration

Starting with Android Oreo, background execution limits are imposed on applications in the background and will destroy them after a certain amount of time. To prevent this it is recommended to configure the ValidicSHealth object with a foreground service notification configuration. This will ensure that results are develivered in near real time.

ValidicSHealth.configure({
    notification_id: 1,
    notification_title: "title",
    notification_clear_text: "Stop", // if set will create a button in the notification that will stop observing data until the next time the app is launched
    notification_icon: "ic_launcher.png" // will look resource folders for file named ic_launcher.png
});

Available Data Types

Samsung provides several data types that can be subscribed to for notification when data changes.

The available data types are:

• com.samsung.health.blood_glucose
• com.samsung.health.blood_pressure
• com.samsung.health.body_temperature
• com.samsung.health.caffeine_intake
• com.samsung.health.exercise
• com.samsung.health.food_info
• com.samsung.health.food_intake
• com.samsung.health.hba1c
• com.samsung.health.heart_rate
• com.samsung.health.oxygen_saturation
• com.samsung.health.sleep
• com.samsung.health.sleep_stage
• com.samsung.health.uv_exposure
• com.samsung.health.water_intake
• com.samsung.health.weight
• com.samsung.shealth.step_daily_trend

NOTE: Data types that are going to be used in your application must be added to the AndroidManifest.xml.

android/app/AndroidManifest.xml

<application name="testApp">
    <meta-data android:name="com.samsung.android.health.platform_type" android:value="rel"/>
    <meta-data android:name="com.samsung.android.health.permission.read" android:value="com.samsung.health.blood_glucose;com.samsung.health.exercise"/>
</application>

Check Read Access for HealthDataTypes

Read access is required to set subscriptions for a dataType.

    let results = await ValidicSHealth.hasReadAccess([ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]);
    if(results[ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]){
        //has access
    }else {
        //does not have access. Adding a subscription will result in an error being emitted and the subscription removed
    }

Request Read Permission for HealthDataTypes

In order to request the end user grant read access to ValidicSHealth use requestPermissions

    let results = await ValidicSHealth.hasReadAccess([ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]);
    if(results[ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]){
        //has access
    }else {
        //does not have access. 
        let results1 = ValidicSHealth.requestPermissions([ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]);
        if(results1[ValidicSHealth.requestPermissions[ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]]){
            //has access
        } else {
            //permission was denied
        }
    }

Request Subscriptions to HealthDataTypes

After read access has been granted for a data type it can be subscribed to for data to automatically be uploaded to the Validic API.

     let results = await ValidicSHealth.hasReadAccess([ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]);
     if(results[ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]){
         ValidicSHealth.requestSubscriptions([ValidicSHealth.HealthDataTypes.DAILY_STEP_COUNT]);
     }

If permission has not been granted and a subscription is attempted then an error event will be thrown and the subscription removed.
Please see (Events)[#events] to listen for the error event.
NOTE: Calling ValidicSession.endSession() will remove all SHealth subscriptions and stop listening for new data.

Fetch historical data

Validic provides the ability to query up to 6 months of data for a subset of data types provided by Samsung Health by querying
an array of ValidicSHealth.HistoricalSetType

Currently 2 historical sets are available

• ValidicSHealth.HistoricalSetType.HistoricalSetTypeFitness - Exercise data
• ValidicSHealth.HistoricalSetType.HistoricalSetTypeRoutine - Step data

ValidicSHealth.fetchHistory([ValidicSHealth.HistoricalSetType.HistoricalSetTypeRoutine]); //fetch last 6 months of walking data

This is will trigger the EVENT_ON_HISTORY_FETCH event described in the Events section

Handle events

To listen for events from SHealth an eventListener should be added to the native event emitter. It is recommended to do this in your comonents componentDidMount method

ValidicSHealth.eventEmitter.addListener(ValidicSHealth.EventNames.EVENT_ON_PERMISSION_CHANGE, (permissions)=>{
    // SHealth permissions have changed
    console.log(permissions.accepted) // array of accepted permissions from the user
    console.log(permissions.denied) // array of permissions denied by the user
});

ValidicSHealth.eventEmitter.addListener(ValidicSHealth.EventNames.EVENT_ON_ERROR, (error)=>{
    // An error has occurred with SHealth
    console.error(error);
});

ValidicSHealth.eventEmitter.addListener(ValidicSHealth.EventNames.EVENT_ON_RECORDS,(recordSummary)=>{
    // Validic has gathered records because of a data type subscription change
    console.log(recordSummary) // summary of how many records  were collected by the subscriptions keyed by the `ValidicSHealth.SummaryTypes`
});

ValidicSHealth.eventEmitter.addListener(ValidicSHealth.EventNames.EVENT_ON_HISTORY_FETCH, (historySummary)=>{
    // Validic data has pulled 6 months of records from SHealth
    console.log(historySummary) // summary of how many records  were collected by the subscriptions keyed by the `ValidicSHealth.HistoricalSetTypes`
});

Events should be removed when they are no longer necessary or when the component listening will be unmounted

componentWillUnmount(){
    ValidicSHealth.eventEmitter.removeAllListeners(ValidicSHealth.EventNames.EVENT_ON_PERMISSION_CHANGE);
    ValidicSHealth.eventEmitter.removeAllListeners(ValidicSHealth.EventNames.EVENT_ON_RECORDS);
    ValidicSHealth.eventEmitter.removeAllListeners(ValidicSHealth.EventNames.EVENT_ON_HISTORY_FETCH);
    ValidicSHealth.eventEmitter.removeAllListeners(ValidicSHealth.EventNames.EVENT_ON_ERROR);
}

Bluetooth

Are you already using our React Native wrapper? If so, are you interested in accessing our React Native Bluetooth framework? Reach out to our customer support team or your Validic Client Success Executive if you'd like to learn more about our Bluetooth support for React Native!

This project integrates Bluetooth capabilities with the Validic Mobile Full SDK to actively and passively collect data from supported Bluetooth Low Energy (LE) devices on behalf of an end user.

Install

To get started, install the framework

npm install react-native-validic-ble-<version>.tgz

or

yarn add react-native-validic-ble-<version>.tgz

Usage

import { ValidicBluetooth } from "react-native-validic-ble";

Peripherals

A BluetoothPeripheral represents a Bluetooth Low Energy profile for interacting with a Bluetooth device. To get a list of all of the BluetoothPeripherals that are supported by the Validic Bluetooth Platform:

let peripherals = await ValidicBluetooth.getAllPeripherals();

To get a BluetoothPeripheral definition by its BluetoothPeripheral.ID identifier:

let peripheral = await ValidicBluetooth.getPeripheralInfo(peripheralId);

Permissions

The following permissions are automatically added to project. They must be requested at runtime before the Validic SDK can connect to a Bluetooth Device:

Android >= Android 12

• android.permission.BLUETOOTH_SCAN
• android.permission.BLUETOOTH_CONNECT

Android < Android 12

• android.permission.BLUETOOTH
• android.permission.BLUETOOTH_ADMIN
• android.permission.ACCESS_COARSE_LOCATION
• android.permission.ACCESS_FINE_LOCATION
• android.permission.ACCESS_BACKGROUND_LOCATION

Pair

Some BluetoothPeripheral profiles require pairing with the device before measurements can be retrieved from the device. These BluetoothPeripherals will have RequiresPairing == true and will have PairingInstruction that can be used to display to the end user:

try{ val peripheral = await ValidicBluetooth.getPeripheralInfo(2); // A&D BP cuff // do something with peripheral.pairingInstructions console.log(peripheral.pairingInstructions); // then pair val result = await ValidicBluetooth.pair({ "peripheralID": 2 }) } catch (e) { console.log(e) }

Read

To take a reading from a BluetoothPeripheral device call readPeripheral

try{ val records = await ValidicBluetooth.readPeripheral({ "peripheralId": 2 }) } catch (e) { console.log(e) }

By default Records that are collected are automatically submitted to the Validic API. To prevent autosubmitting the readings and submitting them manually to the server, use the autoSubmit option and use ValidicSession to submit the records collected.

try{ val records = await ValidicBluetooth.readPeripheral({ "peripheralID": 2, "autoSubmit": false }) await ValidicSession.submitRecords(records) } catch (e) { console.log(e) }

Cancelling an operation

To cancel an inflight Promise after calling ValidicBluetooth.pairPeripheral or ValidicBluetooth.readPeripheral call the ValidicBluetooth.cancelOperation function. If an operation is currently in place, then the Promise returned will call its reject function with a cancellation method.

ValidicBluetooth.readPeripheral({ peripheralId:1 autoSubmit:true }) .then(()=>{ console.log("Paired with Peripheral"); }) .catch(e=>{ console.log(e); }); // ... ValidicBluetooth.cancelOperation();

Passive Reading

ValidicBluetooth allows for registering a set of BluetoothPeripherals to scan and read from automatically in the background. Collected Readings are automatically submitted to the Validic API. The peripherals are persisted across reboots. Use an array of BluetoothPeripheral.peripheralIds to start reading in the background.

await ValidicBluetooth.setPassivePeripherals([1,14,15])

To get a list of BluetoothPeripheral Ids that are being scanning and read in the background

let backgroundPeripherals = await ValidicBluetooth.getPassivePeripherals()

iOS
The host application must be at least launched in the background for readings to be collected from devices when they advertise an available reading.

Android
If the host application is closed by the user and a Bluetooth Peripheral advertises a new reading the App will relaunch and collect the reading.
