`buildfire.services.bluetooth.iBeacon`

danger

This service is deprecated.

iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013.[1] Various vendors have since made iBeacon-compatible hardware transmitters - typically called beacons - a class of Bluetooth low energy (BLE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets, and other devices to perform actions when in close proximity to an iBeacon ref: https://en.wikipedia.org/wiki/IBeacon

Info

This service works only on devices

Requirements

Include iBeacon.js file in widget header right after the buildfire.min.js

`plugin.json`

In plugin.json add iBeacon in your features array "features" : [{"name" : "iBeacon"}]

Methods

`createBeaconRegion()`

buildfire.services.bluetooth.iBeacon.createBeaconRegion(uuid, identifier, minor, major)

Use this factory method to create a beacon region. This synchronous function will return beaconRegion

note

If you specify only a uuid and not the major or minor then it will scan all majors and minors

const beaconRegion = buildfire.services.bluetooth.iBeacon.createBeaconRegion(
  "cd5bdf9e-9339-4678-9c07-c4c627894fe6",
  "myIbeacon"
);

`arguments`

Name	Type	Required	Description
`uuid`	string	yes	iBeacons uuid, must be valid UUID v4
`identifier`	string	no	Unique identifier
`minor`	number	no	iBeacon minor number
`major`	number	no	iBeacon major number

`startMonitoring()`

buildfire.services.bluetooth.iBeacon.startMonitoring(beaconRegion, callback)

Used to tell the OS to begin listening for this region of beacons. When you enter or exit a region events will trigger such as onRegionEntered and onRegionExited. The OS will wake up the app in the background if it's killed and trigger these events. The app will be alive only for a few seconds.

const beaconRegion = buildfire.services.bluetooth.iBeacon.createBeaconRegion(
  "cd5bdf9e-9339-4678-9c07-c4c627894fe6",
  "myIbeacon"
);
buildfire.services.bluetooth.iBeacon.startMonitoring(beaconRegion, (err) => {
  if (err) return console.error(err);

  console.log("Started monitoring on beacon region", beaconRegion);
});

const beaconRegion = buildfire.services.bluetooth.iBeacon.createBeaconRegion(
  "cd5bdf9e-9339-4678-9c07-c4c627894fe6",
  "myIbeacon"

`stopRanging()`

buildfire.services.bluetooth.iBeacon.stopRanging(beaconRegion, callback)

Stop ranging beacons in the region provided.

tip

Make sure you only range when needed since it will drain the battery if you don't.

Name	Type	Description
`minor`	number	iBeacon minor number
`major`	number	iBeacon major number
`rssi`	number	Received Signal Strength Indicator. It is the strength of the beacon's signal as seen on the receiving device. RSSI is used to approximate the distance between the device and the beacon using another value defined by the iBeacon standard: Measured Power (see below).
`proximity`	string	String estimating proximity. Can be: `"ProximityImmediate"` (very close to the beacon), `"ProximityNear"` (about 1-3 m from the beacon), `"ProximityFar"` (further away or the signal is fluctuating too much to make a better estimate) or `"ProximityUnknown"`
`accuracy`	number	Accuracy estimate in meters
`uuid`	string	iBeacons unique uuid

Notes

Since this only works on a mobile device, iBeacons will only function on the widget side of your plugins
There is a limit from the OS on how many UUIDs you can monitor. However, you can have thousands of major and minor ranges
Monitoring a beacon region will trigger events even if your app is killed (unlike ranging). The app will wake up in the background and only live for a few seconds before its killed again
Since Monitoring is always scanning, it does this very passively. For example, it will check only every few seconds (will vary) to see if you have entered a region. It will wait 30 seconds (or so) outside a region to be sure you have left before triggering the exited event :::
