Signalk will accept your ais sentences and forward them to port 10110, just tried it sending to signalk over wifi UDP on 10.10.10.1 10112 from an esp32. Data gets echoed to port 10110 and opencpn sees it.
Should kplex be sending to port 10110? Maybe try sending from kplex to signalk over a different udp port?
