I am working on trying to understand what data is present in the FIT files my devices produce. I am using the FIT SDK and making progress. However, I am finding a lot of unanswered questions. If there a forum for asking such questions? My biggest question at the moment is how to find definitions for the many fields which contain a number. For example DeviceType, DeviceIndex, SourceType. I suspect these can vary by manufacturer, but where does one find definitions for them?
