My thoughts, about NMEA WiFi have finalized ? since my first post in the subject and the Yacht Devices YDWG-02N is now installed in my NMEA2000/ST/NMEA0183 network and works just fine.
I'm already using Raymarine ST => ST NG converter but otherwise I had bought the YDNR-02 instead which should have done the same job.
Please find some thoughts from the installation below.
