node-eddystone-beacon
Create an Eddystone Beacon using Node.js
Eddystone-URL beacons can be used with the Physical Web.
Prerequisites
Requires Node.js and Linux or OS X 10.10 or above with Bluetooth 4.0 hardware.
On Linux, you need to run with sudo
or as root
. See bleno for more info.
Have an older machine or Raspberry Pi? Add a Bluetooth 4.0 USB Adapter.
Install
npm install eddystone-beacon
Usage
var eddystoneBeacon = require('eddystone-beacon');
Options
var options = {
txPowerLevel: -22 // override TX Power Level, default value is -21,
tlmCount: 2, // 2 TLM frames
tlmPeriod: 10 // every 10 advertisements
};
Note: an advertising interval of 100ms is used.
Eddystone-URL
var url = 'http://example.com';
eddystoneBeacon.advertiseUrl(url, [options]);
Eddystone-UID
var namespaceId = '00010203040506070809';
var instanceId = 'aabbccddeeff';
eddystoneBeacon.advertiseUid(namespaceId, instanceId, [options]);
TLM data
Use with interleaved TLM mode, see options above.
Battery Voltage
var batteryVoltage = 500; // between 500 and 10,000 mV
eddystoneBeacon.setBatteryVoltage(batteryVoltage);
Temperature
var temperature = 22.0; // between -128.0 and 128.0
eddystoneBeacon.setTemperature(temperature);
