Problems with NMEA out to VHF radio in OP V2.

[Celestine]

I assume you were using kplex in OP1?

Seems like Openplotter is moving away from kplex (and I was never 100% satisfied with it; it required a restart each time a serial device lost connection) and going all-in on SignalK.

I had a similar issue, so I added support for NMEA output over serial in SignalK last week, it landed in version 1.25 which was released this weekend.

The way it works is that in Server -> Connections, you can configure your connections to emit an event each time you receive an NMEA sentence. Then, on your VHF serial connection, you can choose which events you want to output to your radio. Besides the events you configured on your other connections, you also have the "nmea0183" and "nmea0183out" built-in events, the first is emitted on all incoming nmea0183 events, and the latter is emitted by the signalk-to-nmea0183 plugin.

This is not very well documented at the moment, I'm working on it.

I've successfully used that procedure to send AIS data to my Garmin Echomap back-up "chartplotter", and I'm planning to do that with my VHF radio as well as soon as the snow melts around here.

Thanks!

Have updated SingnalK to 1.25 and configured as you suggested.
Now NMEA data works out to VHF.

Hi,
Can’t you tell how you did to make it work?
Thanks ever so much!

You can see my attached image showing the settings in SignalK and an image showing the outgoing nmea strings from the rs232 port.

Hi
I use usb0 with an usb-serial converter. The pi sees the Profilic port and I have configured just like you (apart from the port name) but no output on port. Ocpn is sending a nice 0183 stream in the udp port. 
Don’t understand this...
