Detailed Description

A routing-lost message is sent by a KNXnet/IP router to notify that KNXnet/IP routing indication frames were lost. The message contains the state of the router or device (QKnx::NetIp::DeviceState) and the number of lost frames.

The following code sample illustrates how to create a routing-lost message about three frames being lost because an error occurred in the IP network:

auto frame = QKnxNetIpRoutingLostMessageProxy::builder()
    .setDeviceState(QKnx::NetIp::DeviceState::IpFault)
    .setLostMessageCount(3)
    .create();
