helix_timex

A Flutter plugin to integrate with Helix Timex smart wearable devices (compatible with CRREPA Bluetooth protocols) on Android.

Features

• Device Discovery: Scan and identify nearby Helix smartwatches.
• Connection Management: Connect to and disconnect from Helix watches using MAC address and device name.
• Biometric Monitoring:
  • Read Heart Rate data and trigger manual measurements.
  • Read SpO2 (Blood Oxygen) levels and trigger manual measurements.
  • Read Blood Pressure (Systolic and Diastolic) and trigger manual measurements.
  • Enable dynamic heart rate monitoring.
• Real-time Streams: Listen to scanning state, connection state, and discovered device details.

Installation

Add helix_timex as a dependency in your pubspec.yaml file:

dependencies:
  helix_timex:
    path: /path/to/helix_timex # Local or git path

Run flutter pub get to fetch the package.

Android Setup

1. Make sure you have Bluetooth and Location permissions configured in your android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- For Android 12+ -->
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

2. If you are obfuscating your application with ProGuard, append these rules to your android/app/proguard-rules.pro:

-keep class com.crrepa.ble.** { *; }
-keep class com.devnation.helix_timex.** { *; }

Usage Example

Initialize and Scan

import 'package:helix_timex/helix_timex.dart';

final HelixTimex timex = HelixTimex();

// Listen to scanning state
timex.getScanningStateStream.listen((isScanning) {
  print("Scanning state: $isScanning");
});

// Listen to discovered devices
timex.deviecFoundStream.listen((device) {
  print("Found device: ${device.deviceName} - ${device.macAddress}");
});

// Start scanning
timex.startScanDevice();

Connect to Device

timex.connect(
  macAddress: "00:11:22:33:44:55",
  deviceName: "HXW01",
);

// Listen to connection state
timex.getConnectionStateStream.listen((state) {
  print("Connection state: ${state.connectionState}");
});

Measure Health Parameters

// Listen to Heart Rate
timex.getHeartRateStream.listen((rate) {
  print("Heart Rate: $rate BPM");
});
timex.measureHeartRate();

// Listen to SpO2
timex.getSpo2Stream.listen((spo2) {
  print("SpO2 level: $spo2%");
});
timex.measureSpo2();

// Listen to Blood Pressure
timex.getBloodPressureStream.listen((bpData) {
  print("Systolic: ${bpData['sbp']}, Diastolic: ${bpData['dbp']}");
});
timex.measureBloodPressure();
