This might be a more general question, but on my FR 255, when I export the GPX data to an XML file, the data points captured appear to be in very infrequent moments. For a 30-minute "walk", the data was captured on average about 15 times per minute. I know, it was only a walk. But the same holds for my runs as well. Usually from 2-9 second gaps between data points.
Is there a way to increase this frequency so it captures it every second of an activity?
