### enum class QBluetoothUuid::ServiceClassUuid

This enum is a convienience type for Bluetooth service class and profile UUIDs. Values of this type will be implicitly converted into a QBluetoothUuid when necessary. Some UUIDs refer to service class ids, others to profile ids and some can be used as both. In general, profile UUIDs shall only be used in a QBluetoothServiceInfo::BluetoothProfileDescriptorList attribute and service class UUIDs shall only be used in a QBluetoothServiceInfo::ServiceClassIds attribute. If the UUID is marked as profile and service class UUID it can be used as a value for either of the above service attributes. Such a dual use has historical reasons but is no longer permissible for newer UUIDs.

### `[explicit]` QBluetoothUuid::QBluetoothUuid(const QString &uuid)

Creates a QBluetoothUuid object from the string uuid, which must be formatted as five hex fields separated by '-', e.g., "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}" where 'x' is a hex digit. The curly braces shown here are optional, but it is normal to include them. If the conversion fails, a null UUID is created. See QUuid::toString() for an explanation of how the five hex fields map to the public data members in QUuid.

### QBluetoothUuid::QBluetoothUuid(const QUuid &uuid)

Constructs a new Bluetooth UUID that is a copy of uuid.

### `[static]` QString QBluetoothUuid::characteristicToString(QBluetoothUuid::CharacteristicType uuid)

See also QBluetoothUuid::CharacteristicType.

### `[static]` QString QBluetoothUuid::descriptorToString(QBluetoothUuid::DescriptorType uuid)

Returns a human-readable and translated name for the given descriptor type represented by uuid.

See also QBluetoothUuid::DescriptorType.

### int QBluetoothUuid::minimumSize() const

Returns the minimum size in bytes that this UUID can be represented in. For non-null UUIDs 2, 4 or 16 is returned. 0 is returned for null UUIDs.
