Support for knx secure over RF

[bhanujarya]

Hi Channel i am looking to use knx secure over RF can you suggest if support for the same is available along with any reference implementation example for the same.
Link for the product: https://weinzierl.de/en/products/knx-rf-usb-interface-stick-340/
Link for the SDK: https://weinzierl.de/en/software/knx/sdk-for-baos-binary-services/

I have successfully loaded the required keywring file and password .

When i am writing the command to relay device

		IndividualAddress dev = new IndividualAddress(sourceAddressB);

		try (var knxLink = new KNXNetworkLinkUsb(device, new RFSettings(dev)); // This process communicator constructor
				var pc = new ProcessCommunicatorImpl(knxLink)) {

			addProccessListners(pc);	
public static void relayOn(ProcessCommunicatorImpl pc, GroupAddress relayAddress) {
		try {
			System.out.println("Inside relay on method ");
			DPTXlatorBoolean onValue = new DPTXlatorBoolean(DPTXlatorBoolean.DPT_BOOL);
			onValue.setValue(true);
			System.out.println("RElay address is " + relayAddress + " on value " + onValue);
			pc.responseTimeout(Duration.ofSeconds(15));

			pc.write(relayAddress, onValue);
		} catch (KNXException e) {
			System.err.println("Exception : on value " + e);
			e.printStackTrace();
		}
	}
}

	public static void addProccessListners(ProcessCommunicatorImpl pc) {
		pc.addProcessListener(new ProcessListener() {
			@Override
			public void groupWrite(final ProcessEvent e) {
				print("write.ind", e);
			}

			@Override
			public void groupReadRequest(final ProcessEvent e) {
				print("read.req", e);
			}

			@Override
			public void groupReadResponse(final ProcessEvent e) {
				print("read.res", e);
			}

			@Override
			public void detached(final DetachEvent e) {
			}
			
			
		});
	}

I am getting

I am able to write to knx secure rf device using ETS Utiltiy. Can you please help in resolution steps for the above issue and any code correction if required

[bmalinowsky]

Maybe you need to supply the RF domain of your RF network to new RFSetttings(...).

Hi @bmalinowsky , i have actually tried both the ways by supplying the domain and without domain , but i am getting
RElay address is 1/1/1 on value DPT 1.002 [true]

I checked this was being used in security layer library of knx , can you please help in how can we pass through security layer and actually communicate with my secure light .

[bhanujarya]

Hi @bmalinowsky , i have got the rf address as 00FA:F4E3725F , i have passed it code
String rfDomain = "00FA:F4E3725F";

        byte[] rfDomainBytes = parseRFDomain(rfDomain);

		IndividualAddress dev = new IndividualAddress(rfDomainBytes);

		try (var knxLink = new KNXNetworkLinkUsb(device, new RFSettings(dev)); // This process communicator constructor
				
				var pc = new ProcessCommunicatorImpl(knxLink)) {

			addProccessListners(pc);
			

			System.out.println("KNX Secure is ready");

But still when i am writing to relay
` DPTXlatorBoolean onValue = new DPTXlatorBoolean(DPTXlatorBoolean.DPT_BOOL);
onValue.setValue(true);
System.out.println("RElay address is " + relayAddress + " on value " + onValue);
pc.responseTimeout(Duration.ofSeconds(50));

	//	try {
			pc.write(relayAddress, onValue);

`
,i am getting timeout execption
