NMEA0183 to Node-red

[PaddyB]

Still not sure why I can't use the Serial In node.

Usually best to let signalk take care of all the connections then if you want to get at the data node-red can get it from signalk. So all serial connections get configured in signalk/connections. 

If you want to control what data goes to a different serial port then signalk events is usually better. Signalk does all the multiplexing you likely need.

Events can be a little confusing at first, might be better thought of as "channels"? I send gps pos data like this - 
USB GPS in> 


USB serial output to VHF (shares with wind data coming in) >



So anything coming in from the GPS gets labeled as gps-nmea and sent out again through the 'wind' usb/serial. All incoming  nmea sentences get sent out again over tcp 10110.
The port addresses above were created by openoplotter with the serial app.
