I have this set up and working now but I was wanting to try and leave the heading info off and replace it with the time or something.
I can easily add the system time but I can't see a way (yet) of getting the gps time out. I am thinking at the moment that I will need to extract it from the NMEA data as the ogps calls don't supply it .
I found the problem. Seems like the file that was created initially by Onion Webapp has all zeroes inside it. The property step was to hit the 'Save to Omega' button to save the actual content into the file.
