Detailed Description

Bluetooth GATT operations used by the API, must be implemented by the target platform.

Before interacting with any of the characteristics, users must first call DiscoverServicesAsync

Member Function Documentation

DisconnectAsync()

Task MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.DisconnectAsync

(

)

Closes the Bluetooth LE connection

Returns

Null when connection is lost

DiscoverServicesAsync()

Task MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.DiscoverServicesAsync

(

)

Discover GATT services and characteristics avaiable on the remote device

Returns

Null when discovery is completed

EnableNotificationsAsync()

Task MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.EnableNotificationsAsync	(	Tuple< Guid, Guid >	gattChar,
		Action< byte[]>	handler
	)

Enable notifications for the characteristic

Parameters

gattChar	Characteristic to enable notifications for
handler	Listener for handling characteristic notifications

Returns

Null when the task is completed

ReadCharacteristicAsync()

Task<byte[]> MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.ReadCharacteristicAsync

(

Tuple< Guid, Guid >

gattChar

)

Reads the requested characteristic's value

Parameters

gattChar

Characteristic to read

Returns

Characteristic's value

ServiceExistsAsync()

Task<bool> MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.ServiceExistsAsync

(

Guid

serviceGuid

)

Checks if a GATT service exists

Parameters

serviceGuid

UUID identifying the service to lookup

Returns

True if service exists, false if not

WriteCharacteristicAsync()

Task MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.WriteCharacteristicAsync	(	Tuple< Guid, Guid >	gattChar,
		GattCharWriteType	writeType,
		byte []	value
	)

Writes a GATT characteristic and its value to the remote device

Parameters

gattChar	GATT characteristic to write
writeType	Type of GATT write to use
value	Value to be written

Returns

Null when the task is completed

Property Documentation

BluetoothAddress

ulong MbientLab.MetaWear.Impl.Platform.IBluetoothLeGatt.BluetoothAddress

get
