  • deviceId

    number optional

  • inquiryRssi

    number optional

    Chrome 44+

    The received signal strength, in dBm. This field is avaliable and valid only during discovery. Outside of discovery it's value is not specified.

  • inquiryTxPower

    number optional

    Chrome 44+

    The transmitted power level. This field is avaliable only for LE devices that include this field in AD. It is avaliable and valid only during discovery.

    Transport optional

    Chrome 76+

    The transport type of the bluetooth device.

  • type

    DeviceType optional

    The type of the device, if recognized by Chrome. This is obtained from the deviceClass field and only represents a small fraction of the possible device types. When in doubt you should use the deviceClass field directly.

  • uuids

    string[] optional

    UUIDs of protocols, profiles and services advertised by the device. For classic Bluetooth devices, this list is obtained from EIR data and SDP tables. For Low Energy devices, this list is obtained from AD and GATT primary services. For dual mode devices this may be obtained from both.

Methods

getAdapterState()

Promise 
chrome.bluetooth.getAdapterState(
  callback?: function,
)

Get information about the Bluetooth adapter.

Parameters

  • callback

    function optional

    The callback parameter looks like: 

    (adapterInfo: AdapterState) => void

    • adapterInfo

      AdapterState

      Object containing the adapter information.

Returns

  • Promise<AdapterState>

    Chrome 91+

    Promises are only supported for Manifest V3 and later, other platforms need to use callbacks.

getDevice()

Promise 
chrome.bluetooth.getDevice(
  deviceAddress: string,
  callback?: function,
)

Get information about a Bluetooth device known to the system.

Parameters

  • deviceAddress

    string

    Address of device to get.

  • callback

    function optional

    The callback parameter looks like: 

    (deviceInfo: Device) => void

    • deviceInfo

      Device

      Object containing the device information.

Returns

  • Promise<Device>

    Chrome 91+

    Promises are only supported for Manifest V3 and later, other platforms need to use callbacks.

getDevices()

Promise 
chrome.bluetooth.getDevices(
  filter?: BluetoothFilter,
  callback?: function,
)

Get a list of Bluetooth devices known to the system, including paired and recently discovered devices.

Parameters

  • filter

    BluetoothFilter optional

    Chrome 67+

    Some criteria to filter the list of returned bluetooth devices. If the filter is not set or set to {}, returned device list will contain all bluetooth devices. Right now this is only supported in ChromeOS, for other platforms, a full list is returned.

  • callback

    function optional

    The callback parameter looks like: 

    (deviceInfos: Device[]) => void

    • deviceInfos

      Device[]

      Array of object containing device information.

Returns

  • Promise<Device[]>

    Chrome 91+

    Promises are only supported for Manifest V3 and later, other platforms need to use callbacks.

startDiscovery()

Promise 
chrome.bluetooth.startDiscovery(
  callback?: function,
)

Start discovery. Newly discovered devices will be returned via the onDeviceAdded event. Previously discovered devices already known to the adapter must be obtained using getDevices and will only be updated using the onDeviceChanged event if information about them changes.

Discovery will fail to start if this application has already called startDiscovery. Discovery can be resource intensive: stopDiscovery should be called as soon as possible.

Parameters

  • callback

    function optional

    The callback parameter looks like: 

    () => void

Returns

  • Promise<void>

    Chrome 91+

stopDiscovery()

Promise 
chrome.bluetooth.stopDiscovery(
  callback?: function,
)

Stop discovery.

Parameters

    () => void

Returns

  • Promise<void>

    Chrome 91+

    Promises are only supported for Manifest V3 and later, other platforms need to use callbacks.
