I am using the Calimero library to try and connect to my KNX system. The stack trace that keeps coming up is this:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'knxNetworkLink' defined in class path resource [io/symphony/knx/config/KnxConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [tuwien.auto.calimero.link.KNXNetworkLink]: Factory method 'knxNetworkLink' threw exception; nested exception is tuwien.auto.calimero.KNXException: connecting 127.0.1.1:41243 10.0.1.223:3671 (bound)

Something is an "invalid argument" but I don't understand what might be the problem. The code below is what I use: It's based on Springboot and I configure the connection via the application.yaml. Those values (only one in this case) get mapped into the KnxProperties object which I use further down to set up the KNXNetworkLinx bean.
application.yaml
knx:
connection:
remoteAddress: 10.0.1.223
@Configuration
@ConfigurationProperties(prefix = "knx")
@Getter @Setter
public class KnxProperties {
private Connection connection;
@Configuration
@Getter @Setter
public static class Connection {
private String remoteAddress;
private Integer remotePort = 3671;
private String localAddress = null;
private Integer localPort = 0;
}
}
