OpenMarine

The Ocpn / connections debug window shows the NMEA messages received or sent via different connections.
With OP2 I understand that we are gradually moving to use signalK as the message server but I cannot see (of have not found it : a facility in the signalK plugin connections to display the messages to testing. 
Am I missing something there or is there an additional program needed/available to monitor message traffic?

In OpenPlotter 1 we had the "Signal K inspector". We could try to port this tool to OpenPlotter 2 but I think this should be a Signal K node server feature. We should ask SK team.

You can also use the instrument panel:
http://localhost:3000/@signalk/instrumentpanel/

or use this to see was is going on in SK server:
http://localhost:3000/signalk/v1/api/vessels/self

NMEA0183 that the server sees is available on port 10110 over tcp so you can do

telnet localhost 10110

from the command line to see what if any 0183 the server is processing.

A quick but not very user friendly way to see the SK traffic is /examples/ url, like http://demo.signalk.org/examples/

Is you have a reasonably well formed feature request like this please create an issue at https://github.com/SignalK/signalk-serve...issues/new
