KNXnetIP implementation in C #

Question

I am developing a C # application to manage my home KNX system. So, I used the ETS3Demo software, and using a proxy server allows you to "see" the IP datagrams sent by ETS3 to the KNX / IP interface.

I have continuity with "Connection_Request", "ConnectionState_Request" and "Disconnect_Request", i.e. I am sending a request datagram and the KNX / IP interface is responding.

The only query that gives me headaches is "Tunnelling_Request". I am sending information in exactly the same way as I am sending previous datagrams, but this one does not seem to work.

I am sending a byte by byte datagram, as you can see in the following code:

byte[] byteToSend1 = { 06, 16, 04, 32, 00, 21, 04 }; string communicationChannel = ComunicationChannelNum.Text; byte bytesnew = Convert.ToByte(communicationChannel); byte[] byteToSend2 = { 00, 00, 17, 00, 188, 224, 00, 00, 09, 01, 01, 00, 129 }; writer.WriteBytes(byteToSend1); writer.WriteByte(bytesnew); writer.WriteBytes(byteToSend2); 

I alredy changed the byte, which corresponds to the source address and group address for the variable "int", and still does not work.

Can someone give me a suggestion or something that I can do wrong.

thanks

Answer 1

For those who come here, looking at the topic:

You can always use the Falcon Library KNX library, which can be downloaded for free, and allows you to pre-perform all operations (runtime and control). This requires that you understand the KNX protocol, although not the most beautiful and clean library, but it works.

Note. You may need to register, but it's free. [I cannot share this here because it violates the License Agreement. Thank you Mr. Bummy!]

Answer 2

I use knx to turn on / off the light, which I used this to send a tunneling request.
