Varia radar data in FIT file

Former Member over 3 years ago

I'm wondering if it is possible to extract information from a Garmin Varia radar that is recorded into a FIT file.When looking at the garmin connect mobile app I see that there is some info recorded into a ConnectIQ field about radar data but I'm not sure how to extract this from a FIT file. I'm currently using the C SDK to look at the FIT files.

Looking at the C SDK, I notice that there's the variables radar_threat_count and radar_threat_level_max inside of FIT_EVENT_MESG. Is this where the data is meant to be recorded?

Any help with this would be greatly appreciated.

Thanks.

The "radar_threat_level_max" value in the Event message was added incase anyone wanted to start writing radar data to FIT Activity files. Since the data would be sparse, using an Event message makes more sense than storing mostly nulls in a Record message. Right now I am unaware of any device that is storing this data.

The My Bike Radar Traffic CIQ data field writes radar data to the Activity file. There may be others, or you could write your own CIQ data field.

There is info here for parsing developer data from FIT files. There is example code in Java, C++, and C#. But the concepts can be applied to the C SDK.

I also wrote a CIQ app that does varied options for using the Radar and provides a centre layout which doesn't obscure the view of the data fields.

Unfortunately, Garmin rejected my app so now, I am using it on my own personal watch. It's a great addition esp to my older Garmin Fenix 3 which doesn't natively support Radar and I can tune(or silence) the beeps and such.
