Calibration

Shen.AI (ANVISA) supports the standard blood-pressure calibration workflow through initializationMode.

Calibration uses external blood pressure readings entered by the user and stores the resulting calibration data locally on the current device or browser, partitioned by userId.

Initialization modes

MEASUREMENT: standard measurement with no calibration data.
CALIBRATION: starts the calibration workflow, requiring external blood pressure readings and multiple SDK scans.
CALIBRATED_MEASUREMENT: applies previously stored calibration data, if available, to adjust blood pressure metrics.

If no matching local calibration data is found, CALIBRATED_MEASUREMENT falls back to the standard measurement flow.

lib/main.dart


final settings = InitializationSettings()
  ..initializationMode = InitializationMode.calibration;
 
final initResult = await ShenaiSdk.initialize(API_KEY, USER_ID, settings: settings);

App.tsx


import { initialize, InitializationMode } from "react-native-shenai-sdk"
 
const initResult = await initialize(API_KEY, USER_ID, {
  initializationMode: InitializationMode.CALIBRATION
})


import { ShenaiSdkCapacitor, InitializationMode } from "capacitor-shenai-sdk"
 
const { value: initResult } = await ShenaiSdkCapacitor.initialize({
  apiKey: API_KEY,
  userId: USER_ID,
  settings: {
    initializationMode: InitializationMode.CALIBRATION
  }
})


using Shenai.Maui;
 
var settings = new InitializationSettings
{
    InitializationMode = InitializationMode.CALIBRATION,
};
 
var initResult = await ShenaiSdk.InitializeAsync(API_KEY, USER_ID, settings);

AppDelegate.swift


let settings = InitializationSettings()
settings.initializationMode = .calibration
 
let initResult = ShenaiSDK.initialize(API_KEY, userID: USER_ID, settings: settings)

MainActivity.kt


val settings = shenaiSDKHandler.defaultInitializationSettings
settings.initializationMode = ShenAIAndroidSDK.InitializationMode.CALIBRATION
 
val initResult = shenaiSDKHandler.initialize(this, API_KEY, USER_ID, settings)

index.ts


shenaiSDK.initialize(
  API_KEY,
  USER_ID,
  {
    initializationMode: shenaiSDK.InitializationMode.CALIBRATION
  },
  initResult => {
    // handle result
  }
)

Important notes

Calibration data is stored locally and does not automatically sync across devices or browsers.
If userId is omitted, calibration data is stored under a default bucket on the current device/browser.
When the calibration workflow finishes successfully, the SDK sends a USER_FLOW_FINISHED event.

See Initialization for the supported ANVISA initialization settings.
