To test Openplotter, (OP), together with OpenCPN,(OC), without connecting to the navigation network on board there are two features
- Using the NMEA generators, found in the OP "Tools" menu
- Use log files which are stored within the SignalK application.
Connect to the Rpi.
As said before SignalK, SK, is the engine in OP so we start with terminating that process so we can redirect SK to the log files.
Open a Terminal window "Application menu => Accessories => Terminal" and type
pkill -f signalk-server
