The QKnxNetIpConnectionStateResponseProxy::Builder class provides the means to create a KNXnet/IP connection state response frame. 更多...

A KNXnet/IP connection state response contains the status of a communication channel between a KNXnet/IP client and a KNXnet/IP server.
In most programs, this class will not be used directly. Instead, the QKnxNetIpTunnel or QKnxNetIpDeviceManagement class is used to establish a functional connection to a KNXnet/IP server.
The common way to create a connection state response is:
auto netIpFrame = QKnxNetIpConnectionStateResponseProxy::builder() .setChannelId(25) .setStatus(QKnx::NetIp::Error::None) .create();
If the KNXnet/IP client does not receive the connection state response within a timeout, or the status of the received response indicates that errors occurred, the client repeats the connection state request three times. It then terminates the connection by sending a disconnect request, QKnxNetIpDisconnectRequestProxy , to the server's control endpoint.
Creates and returns a KNXnet/IP connection state response frame.
注意： The returned frame may be invalid depending on the values used during setup.

Sets the ID of the communication channel to channelId and returns a reference to the builder.
Returns the state of the connection channel established to a KNXnet/IP server to status and returns a reference to the builder.
