Seatalk to Nmea

Hello people. I searched a bit, saw some topics on the subject but nothing working like what im searching.
I would like to know if anyone have a Arduino code that can convert Seatalk info into Nmea info. I have a Nmea to Wifi bridge, and would to feed wind instruments data in it, to send via wifi to my tablet. The wind data is in Raymarine Seatalk, so I would need to convert it to Nmea.
I know theres a bridge to buy on some online stores, but since I have Arduino boards, i only need the code to get there, and I have 0 knawledge on Arduino coding...
Regards

Re: Seatalk to Nmea

If you have no other reason to want Seatalk, I have seen people bridge two connections together on the Raymarine instruments to make it produce NMEA2000 output.
Or else ther is this site: Thomas Knauf ****SeaTalk Technical Reference

Some of the ray pilots already do this for you. Seatalk in. Nmea out. For gps anyways. Not sure about wind

There's some related work going now with signalk-node-server that would probably allow this. There's a Seatalk to SignalK provider and then you could use a SignalK app to view or convert NMEA 0183 or 2K.

Re: Seatalk to Nmea

Thanks all for the replies, im studing the signalk option, I tried my autopilot but It only passes the info about the pilot itself (rudder and compass) all the info input (gps via nmea and wind via seatalk) it does not pass.
A Arduino code the reads Seatalk, and converts in Nmea would do perfectly.
Ill keep looking

Possibly, when you write the code, you could consider making it open source?

Possibly then the code could be used in other applications saving other developers time and work.

Like I mentioned on the first topic, I know 0 about coding, thats my problem. I buy the arduino boards when I find some code I can use. Maybe I can learn in the future about coding but its a big dificult world lolol thats why I ask for help, maybe someone with that kind of knawledge have done it already

With arduino boards costing so little why not get one now to start learning? Cutting your code teeth on seatalk might be aiming a bit high..

Some info here about seatalk and arduino..

Re: Seatalk to Nmea

hi,
I'm also interested in the subject. Being a sailor and an engineer I developed a device to debug NMEA 0183 problems. I plan to expand it to be able to debug also seatalk protocol.
