Navigator/BlueOS NMEA GPS not working

Glad it’s mostly working well
Which part of the NMEA injector is not working as expected?

The instructions I used from cerulean (quoted below) worked with the Pixhawk but when I upgraded to the Navigator they didn’t work.

If you enable pirate mode (in the gear icon in the left hamburger menu), you can go to the NMEA Injector and create a new socket on the default port of 27000. Then DVL or ROVL (via Cerulean Tracker) should be able to send $GPRMC strings to the ROV.

These sockets are not persistent across a reboot. You can manually re-create the socket on each boot. Or you can automate it with the API. I did it with crontab -e.

Go to the bottom of the file, and add this line:
* * * * * curl -X 'POST' 'http://0.0.0.0:2748/v1.0/socks' -H 'accept: application/json' -H 'Content-Type: application/json' -d '{"kind": "UDP","port": 27000,"component_id": 220}'

This command will run once per minute. It’s okay that it runs repeatedly, the API will simply reject the request because the port is in use.
