node-sensortag

Node.js lib for the TI SensorTag and TI CC2650 SensorTag

Prerequisites

• node-gyp install guide
• noble prerequisites

NOTE: Certain API's may not be funcational if your SensorTag is running an older firmware version. You can use TI's iOS or Android apps to update the firmare.

Install

npm install sensortag

Examples

See test.js or sensorTag folder in Tom Igoe's BluetoothLE-Examples repo

Usage

var SensorTag = require('sensortag');

Discover

One

SensorTag.discover(callback(sensorTag));

All

function onDiscover(sensorTag) {
  // ...
}

SensorTag.discoverAll(onDiscover);

SensorTag.stopDiscoverAll(onDiscover);

By id

SensorTag.discoverById(id, callback(sensorTag));
