bluezjs v0.1.1

Bluezjs is a NodeJS library for using Bluetooth Low Energy on Linux systems via BlueZ. At this time it only supports the central mode.

Installation

npm i bluezjs

or

yarn add bluezjs

Example usage

Running an ExpressJS server that initiates a scan for nearby Bluetooth LE devices.

const bluezjs = require("bluezjs");
const express = require("express");

const app = new express();
const http = require("http").Server(app);

app.get("/scan", (req, res) => {
  bluezjs.startDiscovery();
  res.json({ status: "ok" });
});

app.get("/stopScanning", (req, res) => {
  bluezjs.stopDiscovery();
  res.json({ status: "ok" });
});

bluezjs.init().then(() => {
  http.listen(3000);
});

What makes it different?

Bluezjs is using the newest D-Bus library dbus-next which makes it simple to build and use on the newer versions of NodeJS.
