Body battery missing data during cycling bike ride

Are you referring to the dotted line during the first ride or the empty parts in between of orange lines?

The empty parts between the orange lines on my rides. I would expect most of my ride to register high stress.

Stress is not shown during workouts because it's normal to consume energies/body battery during workouts with or without stress. I guess it's also more difficult to get an accurate HRV as you're moving a lot more.

The same goes when you're moving without an activity active...you can see the gray short lines for those moments.

Let me see if i can find something more "scientific" from garmin and i'll add it later in the post but what you're seeing is completely normal.

Thanks for the response. So why does the graph show some yellow stress lines then? It seems like the watch is intermittently reading heart rate data while riding.

Difficult to see from connect mobile as it's not really clear where the activity is starting/ending.

Can you post one from Connect web?

My guess is that you're already outside of the ride when the stress data is recorded.

Is it possible that at the points where GCM is showing a stress measurement during your recorded cycling activity, that you were actually at rest, e.g. stationary at a junction for a while or stopped for a drink etc?

That was my first thought too but i rechecked many of my activities and i don't have any measurements during them...and i have rest moments sometimes while the activity is ongoing. If the cycling activity has "autopause" and he stopped here and there then it's definitely possible.

No rest stops no auto pause no pausing on either of those two rides. My first ride was 40 min second ride was 90 min and there was periods in that ride where the watch stopped showing stress.

As an aside i also tried to do heart rate broadcast to my edge 1030 and it does not work well. The broadcast works inconsistently while riding. I was thinking of trying out a arm warmer over the watch to see if that helps. I am guessing that the watch bounces too much when riding and that lets in the sun light?

Here is a clear example that I got off my computer today. I did a ride from 7:20am to 7:55am today. It looks like the watch worked from about 7:35 to 8:20 this morning with recording body battery. You can see at 7:45 that it was not recording any stress as shown in the photo with no yellow bars. I did not adjust the watch or do anythign different w/ it from when i completed my bike ride at 7:55 this morning.

Does this happen to anyone else? Maybe its a defect in the hardware?

If the ride was intense(could be also if it's not intense...not 100% sure about it) you don't get stress recording for a while after the activity...and if you check the widget on the watch it will show "recovering from activity" or something similar.
