Packages

Quick Start

npm install @beacio/core

import { initBeacio, isIOSSafari } from '@beacio/core/detect';
import { beacio, BeacioError } from '@beacio/core';

// 1. On iOS Safari, detect the extension and prompt install if missing
if (isIOSSafari()) {
  await initBeacio({
    operatorName: 'MyApp',
    banner: { mode: 'sheet' },
    onReady: () => console.log('Extension ready'),
  });
}

// 2. Scan and connect (works on iOS Safari + Chrome + Edge)
const ble = new beacio();
const device = await ble.requestDevice({
  filters: [{ services: ['heart_rate'] }],
});

await device.connect();

// 3. Read a value
const value = await device.read('heart_rate', 'heart_rate_measurement');
console.log('Heart rate:', value.getUint8(1));

// 4. Subscribe to notifications
const unsub = device.subscribe('heart_rate', 'heart_rate_measurement', (v) => {
  console.log('Heart rate:', v.getUint8(1));
});

// 5. Clean up
unsub();
await device.disconnect();
