This class is part of the Qt KNX module and currently available as a Technology Preview, and therefore the API and functionality provided by the class may be subject to change at any time without prior notice.
This frame will be sent during secure KNXnet/IP multicast group communication to keep the multicast group member's timer values synchronized. The frame is therefore sent to the KNXnet/IP routing endpoint on port
3671 of the configured routing multicast address.
The common way to create a timer notify frame is:

Member Function Documentation
Builder::Builder(const Builder &other)
Constructs a copy of other.
Creates a new empty timer notify frame builder object.
Assigns the specified other to this object.
Destroys the object and frees any allocated resources.
QKnxNetIpFrame Builder::create() const
Creates and returns a KNXnet/IP timer notify frame.
Note: The returned frame may be invalid depending on the values used during setup.
See also isValid().
Builder &Builder::setMessageAuthenticationCode(const QKnxByteArray &data)
Sets the AES128 CCM message authentication code (MAC) of the generic KNXnet/IP timer notify frame to data and returns a reference to the builder. The MAC has a fixed size of
Sets the message tag of the generic KNXnet/IP timer notify frame to tag and returns a reference to the builder.
In case of a periodic or initial notify the tag contains a random value. In case of an update notify this is the value of the outdated frame triggering the update.
Builder &Builder::setSerialNumber(const QKnxByteArray &serialNumber)
Sets the serial number to serialNumber and returns a reference to the builder.
Note: The serial number must contain exactly 6 bytes.
Builder &Builder::setTimerValue(quint48 timerValue)
Sets the timer value to timerValue and returns a reference to the builder.
Note: The size of a timer value is limited to 48 bits, so the maximum number can be
281474976710655. Passing a larger value will result in creating an invalid frame.
