Hi all, today I encountered a problem ... if I try to connect to a KNX device on the bus using a L_Data.req Connect request. In this case the TPCI of UNNUMBERED_CONTROL_DATA ... in this case there are only 2 bits which seem to refer to a service id instead of 4 bits APCI However I couldn't find this decribed in the KNX spec ... I would really love some documentation on this especially what the 4 possible service ids are.
