My guesses so far about the .ttbin file format generated by the TomTom cardio GPS watches.
- The file format is a repetition of 1 byte tags followed by N bytes of data with N depending on the tag value.
- The GPS coordinates are a bit different from what the TomTom software extracts as it seems to smooth the data.
- A BPM of zero means that the was no reading, the TomTom software tends to use and old value instead.
- The meaning of some tags and parts of the data is still unknown.
