Bryton 420 route files format
Hey guys,
I'm trying to write a python script to convert .gpx files in the files used by the bryton 420 gps. My idea behind this project is to circumvent the official app, which is clunky to generate routes in and, a couple of times, generated bugs in my planned route if I add external .gpx files.
I found a similar project on GitHub for older bryton models, but I was not able to get all information I needed since the files seems to have been changed in the new models. I also tried to contact the bryton support but had no reply as of today.
My main obstacle currently is to understand how to decode/encode the .fit files that the bryton uses for route storage. Even though it is a .fit, the file formating is proprietary and don't follow the common Garmin .fit structure.
Have anyone tried something similar or know where I can find some information that might point me in the right direction?
