Incorrect PGX file with stationary exercise.

Hi Orux,

This might be related to this bug: https://oruxmaps.forumotion.com/t3078-record-without-gps-fix and is losely related to this feature request: https://oruxmaps.forumotion.com/t2263-possibility-hrm-logging-without-gps-on-record
When I'm indoor cycling (http://en.wikipedia.org/wiki/Indoor_cycling) I'm obviously not moving but I am recording a track with OruxMaps and a heart rate monitor.

After stopping the recording and uploading the exercise to www.trainingstagebuch.org I discovered an anomaly in the way Oruxmaps creates a GPX file for a "non-moving exercise";

Code:

I removed a lot of the data points for clarity and removed the GPS bounds and trackpoints for privacy reasons. Please note that Oruxmaps had a GPS fix throughout the entire exercise (I was in an attic where the GPS sensor could apparently "see" the satellites).

Apparently Oruxmaps only records the first trackpoint with the corresponding heart rate info and then appends all the other hear rate data at the end of the file (as it would with a GPX file of an exercise in which I did move).

Could you please alter this behaviour is such a way that there is a proper trackpoint for each heart rate data point? It would be even better if it was possible to record an exercise without having the GPS switched on but still have correct trackpoints with heart rate data (with a "dummy" gps fix perhaps?) in th GPX file. This would save energy as a GPS fix isn't really required in a stationary exercise.

Edit: I also noticed that the duration of a stationary exercise is not recorded properly. Presumably due to the missing trackpoints?

Hi;

you have to change some settings, if you want to save 1 point per second when you are stationary.

settings--gps
--minimum distance --> to 0 meters

Hi Orux,

Thank you! I did scan through the settings but never realised that this setting would do the trick.
