I see in the fit file there is a field called garmin_product is that the device ID? In this case 2158, where can I find the corresponding device name for that ID.
Thanks

I'm fairly sure that this is the Garmin software part number. You can search the compiler.json files that are downloaded with the SDK manager to find what you're looking for...
C:\Users\vitek>pushd C:\Users\vitek\AppData\Roaming\Garmin\ConnectIQ\Devices C:\Users\vitek\AppData\Roaming\Garmin\ConnectIQ\Devices>findstr /s /c:"\"number\":" compiler.json | findstr /c:"2158" fr735xt\compiler.json: "number": "006-B2158-00"
So if my reading is correct, that fit file was saved with a Forerunner 735XT.
Thanks Travis!
Can always count on you, much appreciated!
