QLowEnergyCharacteristicInfo provides information about a Bluetooth Low Energy service characteristic's name, UUID, value, permissions, handle and descriptors. To get the full characteristic specification and information it is necessary to connect to the service using QLowEnergyServiceInfo and QLowEnergyController classes. Some characteristics can contain none, one or more descriptors. */ /*! \enum QLowEnergyCharacteristicInfo::Error This enum describes the type of an error that can appear. \value NotificationFail Could not subscribe or could not get notifications from wanted characteristic. \value NotConnected GATT Service is not connected. \value UnknownError Unknown error. */ /*! \enum QLowEnergyCharacteristicInfo::Property This enum describes the properties of a characteristic. \value Broadcasting Allow for the broadcasting of Generic Attributes (GATT) characteristic values. \value Read Allow the characteristic values to be read. \value WriteNoResponse Allow characteristic values without responses to be written. \value Write Allow for characteristic values to be written. \value Notify Permits notification of characteristic values. \value Indicate Permits indications of characteristic values. \value WriteSigned Permits signed writes of the GATT characteristic values. \value ExtendedProperty Additional characteristic properties are defined in the characteristic extended properties descriptor. */ /*!
