On the B&G: Settings Page –> network –> nmea0183 –> Ethernet , take note of the IP Address (e.g. 192.168.1.109) and Port (port is usually 10110) . See screenshot below
In Boat Beacon: go to Settings –> scroll down to AIS Sources. Tap Local AIS and select TCP. Then tap Local AIS host and enter the IP address you noted from your B&G device. Then tap Local AIS port and enter the port number – e.g. 10110. Boat Beacon should then see the AIS data from your B&G instrument and the Local AIS light on Boat Beacon should go green,
Be sure your Android device is connected to the GoFree wifi networkIP. If GoFree on your boat doesn’t have a full internet connection available there is also a setting in Boat Beacon to allow you to use your 3G connection at the same time as connected to GoFree to get internet data (like email and the map overlays).
