Laird Capacitor Plugin

This plugin is still in development and is not live on NPM yet!

A Capacitor plugin that communicates with bluetooth low energy laird devices. Supports older devices with the BluetoothAdapter and newer devices uses the BluetoothLeScanner.

Install

npm install laird-capacitor-plugin
npx cap sync

Example

// Import Laird and Device.
import { Laird, Device } from 'laird-capacitor-plugin';

// Initialize the listener first.
Laird.addListener("deviceFoundEvent", (device) => {
    console.log(device);
});

// Start discovering.
Laird.startDiscovering({ periodically: true });
