Description
Requests the GATT Characteristic with the UUID passed as an argument from the GATT Service Profile.
GetCharacteristic expects a single argument, <TBluetoothUUID>, which is the characteristic identifier. GetCharacteristic returns an instance of the TBluetoothGattCharacteristic class for a particular Characteristic UUID.
A GATT characteristic, TBluetoothGattCharacteristic, is a basic data element used to construct a GATT service, BluetoothGattService. The characteristic contains a value as well as additional information and optional GATT descriptors, BluetoothGattDescriptor.
