Member Function Documentation

QBluetoothUuid::QBluetoothUuid(const QUuid &uuid)

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

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(quint128 uuid)

Constructs a new Bluetooth UUID from the 128 bit uuid.

Note that uuid must be in big endian order.

Constructs a new Bluetooth UUID from the 32 bit uuid.

QBluetoothUuid::QBluetoothUuid(quint16 uuid)

Constructs a new Bluetooth UUID from the 16 bit uuid.

Returns a human-readable and translated name for the given service class represented by uuid.

This function was introduced in Qt 5.4.

See also QBluetoothUuid::ServiceClassUuid.

quint16 QBluetoothUuid::toUInt16(bool *ok = nullptr) const

Returns the 16 bit representation of this UUID. If ok is passed, it is set to true if the conversion is possible, otherwise it is set to false. The return value is undefined if ok is set to false.

quint32 QBluetoothUuid::toUInt32(bool *ok = nullptr) const

Returns the 32 bit representation of this UUID. If ok is passed, it is set to true if the conversion is possible, otherwise it is set to false. The return value is undefined if ok is set to false.
