ODK Collect App v1.21.1
ODK Aggregate v2.0.2
I have an ODK form with the file-upload-widget that I want to use to send gps tracks (.gpx) files to an Aggregate server. (I don't want to use GeoODK as I want to use a handheld GPS to collect the data). The files do not appear on the server.
I have run some tests by creating a very small (<500 byte) .gpx file (to exclude file size limits) which I renamed as a .jpg, .pdf and .kml. I tried uploading all four (.gpx, .jpg, .pdf and .kml) to the Aggregate server. Only the .jpg appeared. I received no error message.
