Bluetooth iBeacon Cordova Plugin

This Bluetooth Smart iBeacon WebWorks Cordova Plugin (SimpleBeaconPlugin) is intended to allow WebWorks applications to monitor and detect devices using the Apple de-factor iBeacon standard.

There is a document in the /documents folder describing the plugin's API from JavaScript.

It comes with a sample WebWorks application in the form of a simple iBeacon Monitor application that uses the Bluetooth iBeacon Plugin to monitor for iBeacons.

Applies To

• Apache Cordova for BlackBerry 10

Author

• John Murray

Release History

• V1.0.0 - Initial release

Known Issues

• None

Dependencies

1. BlackBerry Device Software 10.2.1 and greater for the native component.
2. The native component of the plugin in GitHub has been built against BlackBerry Device Software 10.3.1 as this was the most recent version of BlackBerry 10 at the time of posting to GitHub.

API Reference

The following describes the APIs:

• Functions and associated callbacks
  • Common functions
    • initialiseBluetooth()
    • terminateBluetooth()
    • pluginVersion()
  • Bluetooth Smart iBeacon specific
    • startMonitoring(beaconCallback)
    • stopMonitoring()

that are used to interact with this Bluetooth Plugin. The plugin will operate with any Bluetooth Smart Beacon device that implements the iBeacon de-facto standard from Apple.

initialiseBluetooth

Name:

com.blackberry.community.simplebeaconplugin.initialiseBluetooth

Description:

Used to instruct the plugin to connect to the Bluetooth Services on the BlackBerry 10 handset.

You must do this before using any of the other APIs for this plugin.

Once you are finished using Bluetooth in your application you should call the corresponding com.blackberry.community.simplebeaconplugin.terminateBluetooth function before exiting your application.

Type:

Synchronous Function

Usage:

com.blackberry.community.simplebeaconplugin.initialiseBluetooth()

Arguments:

None

Returns:

On success:

{"status" : "OK", "desc" : "Bluetooth Initialised"}

On failure:

{"status" : "ERROR", "desc" : "<description of failure>", "error_code" : <number>}

Example Usage:

Call the function:

var foo = com.blackberry.community.simplebeaconplugin.initialiseBluetooth();

terminateBluetooth

Name:

com.blackberry.community.simplebeaconplugin.terminateBluetooth

Description:

Used to instruct the plugin to disconnect from the Bluetooth Services on the BlackBerry 10 handset.

After you do this you cannot use any of the other APIs for this plugin other than

com.blackberry.community.simplebeaconplugin.initialiseBluetooth().

You should always call this function when you are finished using the Bluetooth services of the plugin in your application.

Type:

Synchronous Function

Usage:

com.blackberry.community.simplebeaconplugin.terminateBluetooth()

Arguments:

None

Returns:

On success:

{"status" : "OK", "desc" : "Bluetooth Terminated"}

On failure:

{"status" : "ERROR", "desc" : "<description of failure>", "error_code" : <number>}

Example Usage:

Call the function:

var foo = com.blackberry.community.simplebeaconplugin.terminateBluetooth();

pluginVersion

Name:

com.blackberry.community.simplebeaconplugin.pluginVersion

Description:

Retrieves the version of the plugin being used as a string of the form: "major.minor.build".

Type:

Synchronous Function

Usage:

com.blackberry.community.simplebeaconplugin.pluginVersion()

Arguments:

None

Returns:

"major.minor.build".

Example Usage:

Call the function:

var version = com.blackberry.community.simplebeaconplugin.pluginVersion();

startMonitoring

Name:

com.blackberry.community.simplebeaconplugin.startMonitoring

Description:

Used to start monitoring for iBeacon advertisement packes and to return any such events via a callback.

Success or failure to initiate monitoring is indicated by a status returned by the function.

Once you are finished monitoring and wish to stop receiving events, you should use the com.blackberry.community.simplebeaconplugin.stopMonitoring() function.

Type:

Asynchronous Function

Usage:

com.blackberry.community.simplebeaconplugin.startMonitoring(beaconCallback)

Arguments:

• beaconCallback -- A function that will be called when an iBeacon advertisment is detected.

Returns:

An immediate status is returned when the function is called.

Immediate status returned by function:

On success:

{"status" : "OK", "desc" : "Monititoring started OK"}

On failure:

{"status" : "ERROR", "desc" : "<description of failure>", "error_code" : <number>}

Results returned by callback:

The iBeacon data from the device will be presented as in this example:

{
"status":"OK",
"event":"IBEACON",
"data":
    {
        "uuid": "CCBF9400E2C011E48A001681E6B88EC1",
        "major": "1",
        "minor": "1",
        "rssi": "-84",
        "txpower": "-64"
},
"desc":"iBeacon event"
}

This represents an iBeacon event with the three identification fields of uuid, major number and minor number. The fields rssi represents the received power in dBm whilst the txpower field is the transmitted power in dBm as measured at 1 metre from the beacon assuming an isotropic antenna. Together rssi and txpower can be used (rssi - txpower) to calculate the channel path power loss in dB. This in turn cal be used to calculate the beacon's distance since we know the power at 1 metre and the power level diminishes as 1/r^2.

Following the convention notifications that are associated with an error condition will be identified by "status": "ERROR" in the JSON object.

Example Usage:

Call the function:

var beaconCallback = function(data) {
    var json = JSON.parse(data);
    if (json.status === 'OK') {
    ...
    }
};
var foo = com.blackberry.community.simplebeaconplugin.startMonitoring(beaconCallback);

stopMonitoring

Name:

com.blackberry.community.simplebeaconplugin.stopMonitoring

Description:

Used to instruct the plugin to stop minitoring iBeacon advertisements.

Type:

Synchronous Function

Usage:

com.blackberry.community.simplebeaconplugin.stopMonitoring()

Arguments:

None

Returns:

On success:

{"status" : "OK", "desc" : "Stopped monitoring for iBeacons OK"}

On failure:

{"status" : "ERROR", "desc" : "<description of failure>", "error_code" : <number>}

Example Usage:

Call the function:

var foo = com.blackberry.community.simplebeaconplugin.stopMonitoring();
