2 years ago Wow, that is amazing, I was hoping to do something similar with an iOS phone app, but hadn't made it very far yet. Yes, the fit file is what my site needs to get the data. You have to add the following DeveloperFields for full compatibility with these first five fields are all "RECORD" messages meaning they are stored every second: radar_ranges (signed two byte int for all 8 vehicles), radar_speeds (unsigned 1 byte int for all 8 vehicles), radar_current (unsigned two byte int, total count up to that point), passing_speed (unsigned 1 byte int, the measured relative speed of just the closest vehicle), passing_speedabs (unsigned 1 byte int, the calculated absolute speed relative plus rider speed).
The next field radar_total is an unsigned 2 byte int for the total vehicle count stored as a session field.
The final field radar_lap is the total number of cars that passed on a given lap and is stored with each lap.
I've also attached a picture of the relevant part of the code from MyBikeTrafficFitContributions.mc
I'm about to leave to race the Tour Divide so I won't be able to work much on this until I get back in July. But feel free to ask me questions here or via direct email brtoone@samford.edu and I will try to get back to you if I'm able.

Hi @kartoone I just discovered your project and I found it awesome (I was thinking to build something similar too before discovering it!) So in the past days I created ARadar, a standalone app for Apple Watch and Garmin Varia https://robertoviola.cloud/2022/05/27/garmin-varia-on-apple-watch-finally/
It will be nice to integrate it together with your project. If I saw it correctly, I just need to export a fit file with the developer items from the radar, isn't it?
What do you think?
