I am trying to send individual address KNX property write/read frames from a Lua event script on LM5 (IP Routing mode, KNX address 2.1.5). The script opens a UDP socket and sends a CONNECT_REQUEST . The CONNECT_RESPONSE always returns status 0x08 (which I assume is no more connections). This happens even after a reboot with no other clients connected. ETS connects successfully using NAT mode. Is it possible for a Lua script to connect to the LM's own tunnelling server, and if so what is the correct approach?
