iOS Integration Guide #

Add awsconfiguration file to your XCode project ##

Initialize SDK with the following Code ##

``javascript
import { NativeModules } from "react-native"
const { VitalsOnlineManager } = NativeModules

try{
const result = await VitalsOnlineManager.initializeWithUserName("userName", "userId", "password", "applicationName")
console.log(result)
}catch(err){
console.log(err)
}

`

Incoming VOIP Calls ##

Use react-native-voip-push-notification to setup VOIP notifications in iOS app. After integrating react-native-voip-push-notification use following functions to register VOIP token and receive incoming call.

`javascript
import { NativeModules } from "react-native"
const { VitalsOnlineManager } = NativeModules

//Register VOIP push notification token with veyetals-online
try{
const result = await VitalsOnlineManager.registerForVoipNotificationsWithToken(token)
console.log(result)
}catch(err){
console.log(err)
}

//Report incoming push notification to veyetals-online
try{
const result = VitalsOnlineManager.reportIncomingCallWithPayload(payload)
console.log(result)
}catch(err){
console.log(err)
}

`

Initiate iOS outgoing call ##

Initiating outgoing call is pretty simple. It only requires remote user's callerId which is the same ID user uses to login into VitalsOnline. Calling user must be logged into the VitalsOnline SDK using VitalsOnlineManager.initializeWithUserName function before he could initiate outgoing call.

`javascript
import { NativeModules } from "react-native"
const { VitalsOnlineManager } = NativeModules

VitalsOnlineManager.startVideoCallWithUserId("")

`

Deregister device for VOIP push notifications ##

Upon user logout deregister device for VOIP push notifications using following function.

`javascript
import { NativeModules } from "react-native"
const { VitalsOnlineManager } = NativeModules

//Register VOIP push notification token with veyetals-online
try{
const result = await VitalsOnlineManager.deregisterFromVoipNotifications()
console.log(result)
}catch(err){
console.log(err)
}

`

iOS - VeyetalsOnlineViewIOS #

VeyetalsOnlineViewIOS is iOS only ReactNative view to scan user vitals using iPhone Camera.

NPM Package instructions are the same as for Android. Following are the system requirements for integration of VeyetalsOnlineViewIOS in React Native iOS application.

iOS Version: 13.0 and above.

Swift Version: 5.0

Camera Usage Permission: Add camera usage string in application's info.plist file

How to use VeyetalsOnlineViewIOS component in iOS app ##

`javascript
import { VeyetalsOnlineViewIOS } from 'react-native-veyetals-online';

async function onCompleted(vitals) {
console.log('Veyetals scanning is complete');
//process vitals - sample output
/*
{
"Heart-rate": "64",
"HRV": "100",
"02-saturation": "97",
"Respiration-rate": "12",
"Systolic": "112",
"Diastolic": "70",
"Stress-levels": "-1",
"snr": "3",
"glucose": "104",
"isValidHeartRate": "true",
"isValidBloodPressure": "true"
}
*/
}

async function onCancelled() {
console.log('Veyetals scanning cancelled');
//update view
}

const customLabels = {
multiCameraAlertTitle: "Multi Camera Alert Title",
multiCameraAlertMessage: "Multi Camera Alert Message",
userMovementErrorMessage: "User Movement Error Message",
faceAlignmentMessage: "Face Alignment Message",
//Custom label for invalid vital alert view title
INVALID_VITAL_ALERT_TITLE: "Invalid vital value",
//Custom labels for invalid vitals captured via face scan

//Custom labels for invalid vitals captured via finger scan

INVALID_PPG_BP_ALERT_MSG: "Invalid blood pressure value",
INVALID_PPG_O2_ALERT_MSG: "Invalid oxygen saturation value"
}

User Management

VeyetalsOnlineViewIOS internally manages users to keep track of service usage. For this purpose it requires following 3 pieces of information from the client app:

CHANNEL_ID: Uniquely identifies an organisation. SDK clients must request CHANNEL_ID from Veyetals team before integrating the component in their application.
APP_ID: Uniquely identifies an app. A channel may have multiple apps using the VeyetalsOnlineViewIOS view. APP_ID is programatically obtained from the client application.
USER_ID: Uniquely identifies an app user for a specific APP_ID and for a specific CHANNEL_ID. Used to track users per app per channel.

These three pieces of information help Veyetals to aggregate the number of users using Veyetals service per app per channel and help generate billing. Before integrating SDK it’s essential for client to contact Veyetals team and activate CHANNEL_ID and APP_ID.

Data Privacy

RNVeyetalsNative component doesn’t store users' video or vitals data; neither on the device nor in the cloud. Therefore, it’s responsibility of the client application to protect user data.
