Discoverer Example

Discoverer shows how to implement and start a discovery agent that discovers KNX/netIP servers on the network.

In the main function, we create the discovery agent:

int main(int argc, char *argv[])
{
    ...
    QKnxNetIpServerDiscoveryAgent agent;

Then, we start the discovery agent:

    ...
    agent.start();

Finally, we recover a list of servers:

    ...
    const auto servers = agent.discoveredServers();
    if (servers.size() > 0) {
        qInfo().noquote() << endl << QString::fromLatin1("%1 server(s) found on the network.")
            .arg(servers.size());
        for (auto server : servers) {
            qInfo().noquote() << QString::fromLatin1("  Server: %1").arg(server.deviceName());
            qInfo().noquote() << QString::fromLatin1("      Individual address: %1").arg(server
                .individualAddress().toString());
            qInfo().noquote() << QString::fromLatin1("      Server control endpoint: %1:%2")
                .arg(server.controlEndpointAddress().toString()).arg(server.controlEndpointPort());

            auto services = server.supportedServices();
            qInfo().noquote() << QString::fromLatin1("    Supported services:");
            for (auto it = services.constBegin(); it != services.constEnd(); ++it) {
                qInfo().noquote() << QString::fromLatin1("      KNXnet/IP %1, Version: %2")
                    .arg(familieToString(it.key())).arg(it.value());
            }
            qInfo() << "";
        }
    } else {
        qInfo().noquote() << "No server(s) found on the network.";
    }

    return 0;
}
