Builder ClassClass Builder is declared in class QKnxNetIpConnectionStateRequestProxy.
|Builder &||setChannelId(quint8 channelId)|
|Builder &||setControlEndpoint(const QKnxNetIpHpai &hpai)|
A KNXnet/IP client sends a connection state request frame regularly to the KNXnet/IP server's control endpoint to check the state of a connection established to the server. The server responds immediately with a connection state response frame, QKnxNetIpConnectionStateResponseProxy.
The common way to create a connection state request is:
auto hpai = QKnxNetIpHpaiProxy::builder().create(); auto netIpFrame = QKnxNetIpConnectionStateRequestProxy::builder() .setChannelId(255) .setControlEndpoint(hpai) .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.
