Properties

Appearance	Gets the BluetoothLEAppearance object for the Bluetooth LE device.
BluetoothAddress	Gets the device address.
BluetoothAddressType	Gets the address type for the Bluetooth LE device.
BluetoothDeviceId	Gets the bluetooth device ID.
ConnectionStatus	Gets the connection status of the device.
DeviceAccessInformation	Gets the DeviceAccessInformation.
DeviceId	Gets the device Id.
DeviceInformation	Gets the device information for the Bluetooth LE device.
GattServices	Gets the read-only list of GATT services supported by the device. Important The GattServices API is deprecated, and it may not be available in future versions of Windows. Instead, use GetGattServicesAsync.
Name	Gets the name of the Bluetooth LE device.
WasSecureConnectionUsedForPairing	Gets a boolean indicating whether the BluetoothLEDevice was paired using a Secure Connection.

Methods

Close()	Closes this Bluetooth LE device. This may close the connection to the device if this is the only app with a connection.
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
FromBluetoothAddressAsync(UInt64)	Returns a BluetoothLEDevice object representing the peer Bluetooth LE device with the given address. See Remarks (in this member topic).
FromBluetoothAddressAsync(UInt64, BluetoothAddressType)	Returns a BluetoothLEDevice object representing the peer device with the given address and address type. See Remarks (in this member topic).
FromIdAsync(String)	Returns a BluetoothLEDevice object for the given Id. See Remarks in the member topic.
GetConnectionParameters()	Retrieves connection parameters for the remote device. If multiple apps or other system scenarios also request these parameters, then the system automatically combines the parameters, where compatible, based on system priority. Note When the device is not connected, the connection parameters are invalid (all zero).
GetConnectionPhy()	Retrieves info about about the Bluetooth LE physical layer (PHY). Note When the device is not connected, the connection PHYs are invalid (all false)
GetDeviceSelector()	Gets an Advanced Query Syntax (AQS) string for identifying all Bluetooth Low Energy (LE) devices. This string is passed to the FindAllAsync or CreateWatcher method in order to get a list of Bluetooth LE devices.
GetDeviceSelectorFromAppearance(BluetoothLEAppearance)	Creates an Advanced Query Syntax (AQS) filter string from a BluetoothLEAppearance object. The AQS string is passed into the CreateWatcher method to return a collection of DeviceInformation objects with the specified appearance.
GetDeviceSelectorFromBluetoothAddress(UInt64)	Creates an Advanced Query Syntax (AQS) filter string from a 64-bit address that represents a Bluetooth LE device. The AQS string is passed into the CreateWatcher method to return a collection of DeviceInformation objects.
GetDeviceSelectorFromBluetoothAddress(UInt64, BluetoothAddressType)	Creates an Advanced Query Syntax (AQS) filter string from a 64-bit address and address type that represents a Bluetooth LE device. The AQS string is passed into the CreateWatcher method.
GetDeviceSelectorFromConnectionStatus(BluetoothConnectionStatus)	Creates an Advanced Query Syntax (AQS) filter string that contains a query for Bluetooth LE devices with the indicated BluetoothConnectionStatus. The AQS string is passed into the CreateWatcher method to return a collection of DeviceInformation objects with the indicated Bluetooth connection status.
GetDeviceSelectorFromDeviceName(String)	Creates an Advanced Query Syntax (AQS) filter string that contains a query for the Bluetooth LE device name. The AQS string is passed into the CreateWatcher method to return a collection of DeviceInformation objects containing the specified Bluetooth LE device name.
GetDeviceSelectorFromPairingState(Boolean)	Creates an Advanced Query Syntax (AQS) filter string that contains a query for Bluetooth LE devices that are either paired or unpaired. The AQS string is passed into the CreateWatcher method to return a collection of DeviceInformation objects.
GetGattService(Guid)	Returns the GATT service with the given service Id. Important The GetGattService API is deprecated, and it may not be available in future versions of Windows. Instead, use GetGattServicesAsync.
GetGattServicesAsync()	Gets the GattDeviceServices for this Bluetooth LowEnergy device.
GetGattServicesAsync(BluetoothCacheMode)	Returns the GattDeviceServices for this Bluetooth LowEnergy device with the specified cache mode.
GetGattServicesForUuidAsync(Guid)	Returns the GattDeviceServices for the Bluetooth LowEnergy device with the specified UUID.
GetGattServicesForUuidAsync(Guid, BluetoothCacheMode)	Returns the GattDeviceServices for the Bluetooth LowEnergy device with the specified UUID.
RequestAccessAsync()	Requests access to the Bluetooth LowEnergy device.
RequestPreferredConnectionParameters(BluetoothLEPreferredConnectionParameters)	Retrieves a Bluetooth LE preferred connection parameters request object for the specified Bluetooth LE preferred connection parameters object.

Events

ConnectionParametersChanged	An event that's raised when the current connection parameters for the device change. The parameters will update only after a connection to the device has been established.
ConnectionPhyChanged	An event that's raised when the current PHY for the device changes. The PHY will update only after a connection to the device has been established.
ConnectionStatusChanged	Occurs when the connection status for the device has changed.
GattServicesChanged	Raised when the list of GATT services supported by the device has changed.
NameChanged	Occurs when the name of the device has changed.
