Hello, does anyone have tried integrating a Trimble R12i GNNS on the Blue Boat? Any tips ? Thanks
Hi @sors -
How does that GPS communicate? Via TCP/IP network or serial? Does it produce more than one serial stream? NMEA? The BlueBoat FAQ details :
How do I integrate an RTK GPS so that more accurate positions are used by the autopilot when navigating?:
Any NMEA position stream can be parsed by the Navigator Autopilot. To receive the messages from a network-connected device simply configure the Autopilot parameters GPS_Type to NMEA, Serial2_Protocol to GPS, and verify no other Serial port # protocol is set to GPS. Finally, under Autopilot Firmware, Serial port Configuration, set Serial 2 to: udpin:0.0.0.0:27000. Then direct your UDP NMEA stream to the IP address of the BlueBoat. Note that these NMEA messages are required for navigation: RMC, GGA, VTG, HDT. This approach uses the ArduPilot driver to interpret the NMEA messages - you can also use the NMEA Injector in BlueOS, which has support for fewer messages. If using a serial connection to bring the NMEA position data to the Navigator serial port 3 or 4, set the appropriate Serial# Protocol parameter to GPS and restart the autopilot. NMEA messages should be sent at 10Hz or faster.

Hello Tony, this GPS can send a NMEA stream via TCP/IP : do you think is can be integrated following these instrucions ? Thanks again
Hi @sors -
Yes! The GPS will need to be configured to have an IP address on the right network, something like 192.168.2.X where X is a number that doesn’t conflict with other devices - so not 1, 2, or another number that may be in use. Perhaps 192.168.2.25 would work?
Then you just configure the GPS to stream UDP NMEA messages to the address of the control computer - 192.168.2.2. The instructions shared are carried out in BlueOS and you’ll be all set!
