BC 3.2.1 still doesn't save Cadence data

I just tested to see of BC saves the Cadence data in a GPX and TCX file. No it does not, so I assume it does not save HeartRate data either.

I hope this isn't confusing, but here is a TrkPt from before/after of GPX & TCX saved data. The original .gpx was from an Oregon 450. I used TCX Converter to convert the .gpx file to a TCX file.

TCX file Before opening in BC:
<Trackpoint>
<Time>2011-06-04T17:26:02Z</Time>
<Position>
<LatitudeDegrees>47.544988</LatitudeDegrees>
<LongitudeDegrees>-116.334362</LongitudeDegrees>
</Position>
<AltitudeMeters>646.14</AltitudeMeters>
<DistanceMeters>0</DistanceMeters>
<Cadence>0</Cadence>
<SensorState>Absent</SensorState>
</Trackpoint>

TCX file After opening in BC & verifying Cadence is displayed in Properties/Elevation Profile then Saved as TCX file (no additional adding or moving TrkPts etc) :
<Trackpoint><Time>2011-06-04T17:26:02Z</Time><Position><LatitudeDegrees>47.544988039880991</LatitudeDegrees><LongitudeDegrees>-116.33436203934252</LongitudeDegrees></Position><AltitudeMeter

s>646.13999999999999</AltitudeMeters></Trackpoint>


GPX file Before:
<trkpt

lat="47.544982"lon="-116.334145"><ele>649.03</ele><time>2011-06-04T17:26:27Z</time><extensions><gpxtpx:TrackPointExtension><gpxtpx:cad>45</gpxtpx:cad></gpxtpx:TrackPointExtension></extensions>

</trkpt>


GPX file After:
<trkpt lat="47.544988039880991" lon="-116.33436203934252">
<ele>646.13999999999999</ele>

  • I can confirm the loss of the heart rate information with BC 3.2.1.
    I tested it on a GPSMAP 62s and with an Oregon 550.

    Any editing of the GPX Track file (on the GPS) will reformat the whole file as mentioned above and removes the heart rate and cadence information.

    If you copy the Track file to &#8220;My Collection&#8221; first and edit the track then, heart rate and cadence data seems to be preserved.

    But that&#8217;s actually not what I want. I&#8217;d rather edit the file on the GPS. I thought this was the big improvement of having the GPS actually show up as a drive on your computer and allowing you to directly modify the data. At the moment this means data loss to me!

  • Confirmation of Heart Rate Problem and a New Problem

    I am also having the problem with the heart rate info being lost when I modify a gpx in Basecamp 3.2.1. I worked on the gpx while it was in my Oregon 450 before I uploaded it to Garmin Connect. I wanted to remove the points prior to starting my bike ride. When I then tried to load the file into Garmin Connect it would not accept it. Someone had told me that the file name needs to be the start time of the track (first point). So I had to change the file name to get it to upload. I then found that my heart rate info was gone.

    So, two Basecamp problems:

    1) Heart rate info is removed if the file is modified in Basecamp.
    2) If the first points in the gpx file are removed, Basecamp will change the file name to something other than the time of the first point. Then the gpx cannot be uploaded to Garmin Connect.
