Problems with NMEA out to VHF radio in OP V2.
#1
No problems with OP Version 1, but can't get NEMA data out to VHF radio in OP version 2.
(If I start diagnostics in kplex  Device 3 starts broadcasting but SignalK stops working and no localhost in OPENCPN))

(Device 1) AIS<=======(RS232 to USB cable)=======>{USB}(Pi). ok!

(Device 2) B&G plotter NEMA port<=======(RS232 to USB cable)=======>{USB}(Pi). ok!

(Device 3)B&G VHF radio NMEA port<=======(RS232 to GPIO)=======>{Pins: RX TX GND}(Pi). Problem??

Any idea what I can do?

What are you using for the interface between RS232 and GPIO? You'll need some sort of TTL to RS232 converter. You could also use another USB to RS232 converter cable.

I use TTL to RS232 converter.

(USB ports are used by AIS, plotter, Wifi and keyboard / mouse)

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.

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

Hi
I have the same need but I don’t fully understand how to set this up. Is it possible that you give an a bit more detailed description?

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

Celestine, can you elaborate your question? I explained how I made it work in my above message; if you need more details I need to know in which specific area before I waste time explaining something you might already know...

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