Mutual Mobile Bluetooth LE Plugin

This is a Cordova Bluetooth LE plugin based on randdusing/BluetoothLE, but rewritten to be more robust, support multiple devices, and have a more comfortable API (Promise-based, each method does exactly one thing). The API is based on the Chrome Bluetooth low energy API. Some signatures have been modified because:

1. We like the Promise API for asynchronous code
2. I couldn't tell why many methods don't reference the device address in Chrome's API. It seems pretty necessary to me to distinguish between multiple devices.

There are two parts of Chrome's API needed to interact with Bluetooth low energy devices:

chrome.bluetooth

Methods

• getAdapterState () : AdapterState
• getDevice (String deviceAddress) : Device
• getDevices () : Device
• startDiscovery () : void
• stopDiscovery () : void

Types

AdapterState

• address : String
• name : String
• enabled : boolean
• discovering : boolean

Device

• address : String
• name : String
• rssi : int
• connected : boolean
• uuids : Service
  • list of services either from advertisement data during a scan or from discovered services on connected devices

Events

• 'onDeviceAdded' : Device
  • called when a device has been discovered
• 'onDeviceDropped' : Device
  • (not in Chrome) called when a connected Device is disconnected, e.g. going out of range. Boils down to "a device disconnected, but nobody asked for it to be"
• 'onAdapterStateChanged' : AdapterState
  • called when the Bluetooth adapter turns on or off

chrome.bluetoothLowEnergy

Methods

• connect (String deviceAddress) : Device
• disconnect (String deviceAddress) : void
• getService (String deviceAddress, String serviceId) : Service
• getServices (String deviceAddress) : Service
• getCharacteristic (String deviceAddress, String serviceId, String characteristicId) : Characteristic
• getCharacteristics (String deviceAddress, String serviceId) : Characteristic
• getIncludedServices (String deviceAddress, String serviceId) : Service
• getDescriptor (String deviceAddress, String serviceId, String characteristicId, String descriptorId) : Descriptor
• getDescriptors (String deviceAddress, String serviceId, String characteristicId) : Descriptor
• readCharacteristicValue (String deviceAddress, String serviceId, String characteristicId) : ArrayBuffer
• writeCharacteristicValue (String deviceAddress, String serviceId, String characteristicId, ArrayBuffer value) : void
• startCharacteristicNotifications (String deviceAddress, String serviceId, String characteristicId) : void
• stopCharacteristicNotifications (String deviceAddress, String serviceId, String characteristicId) : void
• readDescriptorValue (String deviceAddress, String serviceId, String characteristicId, String descriptorId) : ArrayBuffer
• writeDescriptorValue (String deviceAddress, String serviceId, String characteristicId, String descriptorId, ArrayBuffer value) : Descriptor

Types

Service

• uuid : String
• isPrimary : boolean
• instanceId : String
• deviceAddress : String

Characteristic

• uuid : String
• service : String
  • UUID of the parent Service
• properties : Array
  • one or more of: "broadcast", "read", "writeWithoutResponse", "write", "notify", "indicate", "authenticatedSignedWrites", "extendedProperties", "reliableWrite", or "writableAuxiliaries"
• instanceId : String
• value : ArrayBuffer

Descriptor

• uuid : String
• characteristic : String
  • UUID of the parent Characteristic
• value : ArrayBuffer

Events

• 'onCharacteristicValueChanged' : Characteristic
  • callback for a Characteristic notification/indication
• 'onDescriptorValueChanged' : Descriptor
  • callback for a Descriptor notification/indication

Extras

• isSupported () : boolean
  • true if the current device supports Bluetooth LE communication
• isConnected (String deviceAddress) : boolean
  • true if the specified device is connected to the phone's bluetooth adapter
