Detailed Description

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 by a KNXnet/IP secure client to the control endpoint of the KNXnet/IP secure server to initiate the secure session setup handshake for a new secure communication channel. The maximum time a KNXnet/IP secure client will wait for a response of the KNXnet/IP secure server is 10 seconds.

The common way to create a session request frame is:

auto publicKey = ... // create Client Public Value X

auto netIpFrame = QKnxNetIpSessionRequestProxy::builder()

Member Function Documentation

Builder::Builder(const Builder &other)

Constructs a copy of other.


Creates a new empty session request frame builder object.

Builder &Builder::operator=(const Builder &other)

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 session request frame.

Note: The returned frame may be invalid depending on the values used during setup.

See also isValid().

Builder &Builder::setControlEndpoint(const QKnxNetIpHpai &hpai)

Sets the control endpoint of the KNXnet/IP session request frame to hpai and returns a reference to the builder.

Builder &Builder::setPublicKey(const QKnxByteArray &publicKey)

Sets the unencrypted data of the KNXnet/IP session request frame to publicKey and returns a reference to the builder. The public key needs to be generated using the Curve25519 algorithm and has a fixed size of 32 bytes.
