Bluetooth BLE Connectivity

Communicate natively with external Bluetooth Low Energy (BLE) peripherals and IoT hardware. Nativine embeds native CoreBluetooth (iOS) and Android Bluetooth Central Manager SDKs, allowing web applications to scan, connect, read, and write GATT characteristics.

1. Overview & Native Capabilities

Connecting web software to physical hardware devices requires low-level Bluetooth access. Nativine's native Bluetooth BLE plugin provides direct GATT service communication for IoT, fitness, and medical devices:

• Peripheral Scanning & Discovery: Scan for nearby BLE devices broadcasting specific GATT service UUIDs.
• GATT Service & Characteristic I/O: Read sensors, subscribe to GATT notifications, and write data packets directly to connected hardware.
• Background BLE Connections: Maintain persistent Bluetooth connections even when the app is backgrounded.

2. No-Code App Builder Setup Guide

Nativine App Builder Configuration

1. Open the Nativine App Builder at /web-to-app-converter-pro.
2. Click Add-ons & Plugins in the left builder menu and locate Bluetooth BLE Connectivity.
3. Toggle Bluetooth BLE Connectivity to ON (or click Enable), then click Config.
4. Configure your required settings, permissions descriptors, or target web parameters.
5. Click Save Config and navigate to the Builds tab to compile your mobile application.

3. Native JS Bridge API Reference

To scan for BLE hardware peripherals or write data to a GATT characteristic in JavaScript, call nativine.bluetooth.startScan():

// Scan for BLE devices
nativine.bluetooth.startScan({
  serviceUUIDs: ['180D'], // Heart Rate Service UUID
  callback: 'onDeviceFound'
});

// Write data byte array to GATT characteristic
nativine.bluetooth.writeCharacteristic({
  deviceId: 'device_mac_or_uuid',
  serviceUUID: '180D',
  characteristicUUID: '2A37',
  dataBase64: 'AQIA',
  callback: 'onWriteComplete'
});
