Anyone sending Signal-k from Arduino?

[seandepagnier]

Hi,
I've just built a prototype of a wide sensor for my boat using parts of the weathersensor code from pypilot based on an Arduino Nano. I could of course use the NMEA0183 output as pypilot is doing but I also have an ethernet shield available so I was thinking of going directly for signal-k instead of over NMEA. Is there anyone who has done this?

It maybe makes sense with the ethernet shield as you can create a udp connection or even websocket.

It would make perfect sense for a 3d wind sensor, or wind sensor that gives data besides only speed and direction.

Converting NMEA to signalk is well supported, so unless you have data that cannot be represented in NMEA I don't really see the advantage of signalk here.

It is so much to read up on (being new to openplotter) so a pointer on how to go about this would be really appreciated (unless it is a stupid idea -??)

The reason for not using the pypilot full implementation is also that I already have the barometric sensor in openplotter (directly on the PI3) and that my wind instruments are 4-20mA units so that is different from the pypilot implementation anyhow...

How is your instrument different? Details please! What does "4-20mA" mean?

Did you make the instruments?
