This plugin enables communication between a phone and Bluetooth Low Energy (BLE) peripherals.
The plugin provides a simple JavaScript API for iOS and Android.
- Scan for peripherals
- Connect to a peripheral
- Read the value of a characteristic
- Write new value to a characteristic
- Get notified when characteristic's value changes
Advertising information is returned when scanning for peripherals. Service, characteristic, and property info is returned when connecting to a peripheral. All access is via service and characteristic UUIDs. The plugin manages handles internally.
Simultaneous connections to multiple peripherals are supported.
This plugin isn't intended for scanning beacons. Try cordova-plugin-ibeacon for iBeacons.
If you want to create Bluetooth devices, try cordova-plugin-ble-peripheral.
See the examples for ideas on how this plugin can be used.
- iOS
- Android (4.3 or greater)
$ cordova plugin add cordova-plugin-ble-central
$ phonegap plugin add cordova-plugin-ble-central
Edit config.xml to install the plugin for PhoneGap Build.
<gap:plugin name="cordova-plugin-ble-central" source="npm" />
<preference name="phonegap-version" value="cli-6.1.0" />
This plugin is included in iOS and Android versions of the PhoneGap Developer App.
Note that this plugin's id changed from com.megster.cordova.ble to cordova-plugin-ble-central as part of the migration from the Cordova plugin repo to npm.
For iOS, apps will crash unless they include usage description keys for the types of data they access. Applications targeting iOS 13 and later, define NSBluetoothAlwaysUsageDescription to tell the user why the application needs Bluetooth. For apps with a deployment target earlier than iOS 13, add NSBluetoothPeripheralUsageDescription. Both of these keys can be set when installing the plugin by passing the BLUETOOTH_USAGE_DESCRIPTION variable.
$ cordova plugin add cordova-plugin-ble-central --variable BLUETOOTH_USAGE_DESCRIPTION="Your description here"
See Apple's documentation about Protected Resources for more details. If your app needs other permissions like location, try the cordova-custom-config plugin.

Scan and discover BLE peripherals.
ble.scan(services, seconds, success, failure);
Function scan scans for BLE devices. The success callback is called each time a peripheral is discovered. Scanning automatically stops after the specified number of seconds.
{
"name": "TI SensorTag",
"id": "BD922605-1B07-4D55-8D09-B66653E51BBA",
"rssi": -79,
"advertising": /* ArrayBuffer or map */
}
Advertising information format varies depending on your platform. See Advertising Data for more information.
With Android SDK >= 23 (6.0), additional permissions are required for Bluetooth low energy scanning. The location permission ACCESS_COARSE_LOCATION is required because Bluetooth beacons can be used to determine a user's location. If necessary, the plugin will prompt the user to allow the app to access to device's location. If the user denies permission, the scan failure callback will receive the error "Location permission not granted".
Location Services must be enabled for Bluetooth scanning. If location services are disabled, the failure callback will receive the error "Location services are disabled". If you want to manage location permission and screens, try the cordova-diagonostic-plugin or the Ionic Native Diagnostic plugin.
- services: List of services to discover, or [] to find all devices
- seconds: Number of seconds to run discovery
- success: Success callback function that is invoked which each discovered device.
- failure: Error callback function, invoked when error occurs. [optional]
ble.scan([], 5, function(device) {
console.log(JSON.stringify(device));
}, failure);
Scan and discover BLE peripherals.
ble.startScan(services, success, failure);
Function startScan scans for BLE devices. The success callback is called each time a peripheral is discovered. Scanning will continue until stopScan is called.

Scan and discover BLE peripherals, specifying scan options.
ble.startScanWithOptions(services, options, success, failure);
Function startScanWithOptions scans for BLE devices. It operates similarly to the startScan function, but allows you to specify extra options (like allowing duplicate device reports). The success callback is called each time a peripheral is discovered. Scanning will continue until stopScan is called.

Set device pin
ble.setPin(pin, [success], [failure]);
Function setPin sets the pin when device requires it.
- pin: Pin of the device as a string
- success: Success callback function that is invoked when the function is invoked. [optional]
- failure: Error callback function, invoked when error occurs. [optional]
Connect to a peripheral.
ble.connect(device_id, connectCallback, disconnectCallback);
Function connect connects to a BLE peripheral. The callback is long running. The connect callback will be called when the connection is successful. Service and characteristic info will be passed to the connect callback in the peripheral object.
The disconnect callback is called if the connection fails, or later if the peripheral disconnects. When possible, a peripheral object is passed to the failure callback. The disconnect callback is only called when the peripheral initates the disconnection. The disconnect callback is not called when the application calls ble.disconnect. The disconnect callback is how your app knows the peripheral inintiated a disconnect.
Android can connect to peripherals using MAC address without scanning. If the MAC address is not found the connection will time out.
For iOS, the plugin needs to know about any device UUID before calling connect. You can do this by calling ble.scan, ble.startScan, ble.connectedPeripheralsWithServices, or ble.peripheralsWithIdentifiers so the plugin has a list of available peripherals.
- device_id: UUID or MAC address of the peripheral
- connectCallback: Connect callback function that is invoked when the connection is successful.
- disconnectCallback: Disconnect callback function, invoked when the peripheral disconnects or an error occurs.
Establish an automatic connection to a peripheral.
ble.autoConnect(device_id, connectCallback, disconnectCallback);
Automatically connect to a device when it is in range of the phone. When the device connects, the connect callback is called with a peripheral object. The call to autoConnect will not time out. It will wait forever until the device is in range. When the peripheral disconnects, the disconnect callback is called with a peripheral object.
Calling ble.disconnect will stop the automatic reconnection.
Both the connect and disconnect callbacks can be called many times as the device connects and disconnects. Do not wrap this function in a Promise or Observable.
On iOS, background notifications on ios must be enabled if you want to run in the background. On Android, this relies on the autoConnect argument of BluetoothDevice.connectGatt(). Not all Android devices implement this feature correctly.
See notes about scanning before connecting
- device_id: UUID or MAC address of the peripheral
- connectCallback: Connect callback function that is invoked when the connection is successful.
- disconnectCallback: Disconnect callback function, invoked when the peripheral disconnects or an error occurs.
Disconnect.
ble.disconnect(device_id, [success], [failure]);
Function disconnect disconnects the selected device.

- failure: Error callback function, invoked when error occurs. [optional]
requestMtu
ble.requestMtu(device_id, mtu, [success], [failure]);
This function may be used to request (on Android) a larger MTU size to be able to send more data at once. This can be useful when performing a write request operation (write without response), the data sent is truncated to the MTU size. The resulting MTU size is sent to the success callback. The requested and resulting MTU sizes are not necessarily equal.
- Android
- device_id: UUID or MAC address of the peripheral
- mtu: MTU size
- success: Success callback function that is invoked when the MTU size request is successful. The resulting MTU size is passed as an integer.

function(mtu){
alert("MTU set to: " + mtu);
},
function(failure){
alert("Failed to request MTU.");
}
);

- success: Success callback function that is invoked when the connection is successful. [optional]
- failure: Error callback function, invoked when error occurs. [optional]
refreshDeviceCache
ble.refreshDeviceCache(deviceId, timeoutMillis, [success], [failure]);
Some poorly behaved devices show old cached services and characteristics info. (Usually because they don't implement Service Changed 0x2a05 on Generic Attribute Service 0x1801 and the central doesn't know the data needs to be refreshed.) This method might help.
NOTE Since this uses an undocumented API it's not guaranteed to work.
- Android
- deviceId: UUID or MAC address of the peripheral
- timeoutMillis: timeout in milliseconds after refresh before discovering services
- success: Success callback function invoked with the refreshed peripheral. [optional]

// send a 3 byte value with RGB color
var data = new Uint8Array(3);
data[0] = 0xFF; // red
data[1] = 0x00; // green

- failure: Error callback function, invoked if the user does not enabled Bluetooth.
ble.enable(
function() {
console.log("Bluetooth is enabled");
},

"advertising": [2,1,6,3,3,15,24,8,9,66,97,116,116,101,114,121],
"rssi": -55
}
After connecting, the peripheral object also includes service, characteristic and descriptor information.

Bluetooth advertising data is returned in when scanning for devices. The format varies depending on your platform. On Android advertising data will be the raw advertising bytes. iOS does not allow access to raw advertising data, so a dictionary of data is returned.
The advertising information for both Android and iOS appears to be a combination of advertising data and scan response data.
Ideally a common format (map or array) would be returned for both platforms in future versions. If you have ideas, please contact me.
{
"name": "demo",
"id": "00:1A:7D:DA:71:13",
"advertising": ArrayBuffer,
"rssi": -37
}
Convert the advertising info to a Uint8Array for processing. var adData = new Uint8Array(peripheral.advertising). You application is responsible for parsing all the information out of the advertising ArrayBuffer using the GAP type constants. For example to get the service data from the advertising info, I parse the advertising info into a map and then get the service data to retrieve a characteristic value that is being broadcast.
Note that iOS uses the string value of the constants for the Advertisement Data Retrieval Keys. This will likely change in the future.
{
"name": "demo"
"id": "15B4F1C5-C9C0-4441-BD9F-1A7ED8F7A365",
"advertising": {
"kCBAdvDataLocalName": "demo",
"kCBAdvDataManufacturerData": {}, // arraybuffer data not shown
"kCBAdvDataServiceUUIDs": [
"721b"
],
"kCBAdvDataIsConnectable": true,
"kCBAdvDataServiceData": {
"BBB0": {} // arraybuffer data not shown
},
},
"rssi": -61
}
Some of the values such as kCBAdvDataManufacturerData are ArrayBuffers. The data won't print out, but you can convert it to bytes using new Uint8Array(peripheral.advertisting.kCBAdvDataManufacturerData). Your application is responsible for parsing and decoding any binary data such as kCBAdvDataManufacturerData or kCBAdvDataServiceData.
function onDiscoverDevice(device) {
// log the device as JSON
console.log('Found Device', JSON.stringify(device, null, 2));
// on iOS, print the manufacturer data if it exists
if (device.advertising && device.advertising.kCBAdvDataManufacturerData) {
const mfgData = new Uint8Array(device.advertising.kCBAdvDataManufacturerData);
console.log('Manufacturer Data is', mfgData);
}
}
ble.scan([], 5, onDiscoverDevice, onError);
This plugin uses typed Arrays or ArrayBuffers for sending and receiving data.
This means that you need convert your data to ArrayBuffers before sending and from ArrayBuffers when receiving.
// ASCII only
function stringToBytes(string) {
var array = new Uint8Array(string.length);
for (var i = 0, l = string.length; i < l; i++) {
array[i] = string.charCodeAt(i);
}
return array.buffer;
}
// ASCII only
function bytesToString(buffer) {
return String.fromCharCode.apply(null, new Uint8Array(buffer));
}
You can read more about typed arrays in these articles on MDN and HTML5 Rocks.
UUIDs are always strings and not numbers. Some 16-bit UUIDs, such as '2220' look like integers, but they're not. (The integer 2220 is 0x8AC in hex.) This isn't a problem with 128 bit UUIDs since they look like strings 82b9e6e1-593a-456f-be9b-9215160ebcac. All 16-bit UUIDs should also be passed to methods as strings.
Android applications will continue to receive notification while the application is in the background.
iOS applications need additional configuration to allow Bluetooth to run in the background.
