Has anyone used the Activity.WorkoutStep details available in 3.2?

I have not been able to simulate a workout in the Garmin simulator (using version 2.3.5). When I select a fit file with a workout and then set simulate data all matrics stay at zero and a dump of workoutdata delivers a null.

Has anyone succeeded?

No, the simulator does not support workouts. You have to test workouts 'in the field', sideloading a device.

I'm almost certain I've been able to do this, but it is limited. You can play back a FIT file workout and simulate data together. I can't recall exactly how to do it.

I just used this code to do it.

You play back the fit file, then simulate data, then start the workout (Press Start/Stop on the simulated device, or click Data Fields > Timer > Start Activity).

Thank you Travis.ConnectIQ !

yeah. this works. Is there also simulated data when playing back the FIT workout file? I'm not getting any simulated values in the simulator. No Cad. No Power etc

There should be simulated data. I'm pretty sure there was when I tested this using the code above.

Travis.ConnectIQ I just tried it again. I loaded the FIT file you provided Run_Workout_Test.FIT. and 

Travis.ConnectIQ said:

I tried all these and while the fit file plays, Pressing the start/stop etc did not have any simulated values on the screen. When I mean simulated values, I mean things like HR keeping on looping like an actual outdoor run for example. 

I've filed WERETECH-10881 for this.
