I want to save every x minutes the NMEA data to a file or sqlite database. Found that you can save data with kplex to a file, but can't find the configuration file.
Where can I find the configuration file? Or is there a better way to save the NMEA data ever x minutes?

Swokey
I'm using custom actions triggered every x minutes/seconds to update a RRDTOOL database with NMEA data (temperatures, wind), then using the data to plot readings later on.
I have written a few words about it at my boats website, it's in Norwegian but feel free to ask if the images are not sufficient to get the drift? :-)

Arne, fantastic, thanks for the link and taking some time to write it up - I've wondering abouty how to do just this for some time.
Up and running, thanks for the message about rrdtools. I couldn't get the command line working to directly update the database but used the command line to call a bash script instead which seems to be working OK.
So saving data mostly up and running now with a Web page to pick what you want to look at and from when to when. Not at all difficult with openplotter actions.
Well. I managed to corrupt my original SD-card and had to reinstall more or less from scratch, so I figured it would be just as well to try out the 0.9.0-build.
I have installed and set up everything, and am kind of getting into the changes from earlier versions, but I have problems getting the data out to my RRD db's using my custom actions.
Have the variables changed name, which should I use here for the 1-wire sensors?
Name, as before, ENGINE, EXHAUST, INSIDE - seems not to work?
Signal K full string? propulsion.ENGINE.coolantTemperature ?

or what?
I'm using the short variable names from the nmea inspector.
