Need help from you. I am trying to get DPT (datatype of the group address) from frame when I get it. Frame is a kind of a message from KNX bus that is available on the bus every time something happens on the bus - the value is changed, the value is read etc. Qt provides en example how to deal with the frame - one canget source/destination addresses of the frame, the format of the frame etc. However I do not understand how to get DPT of the value that is sent from group addresses. There is an official KNX tool called ETS and it shows DPT of the value as well as the value in human redable form when the frame has come.

Howit could be done with Qt? Any suggestions?

Thank you in advance.
