vivoactive hr not starting the optical sensor for CIQ apps

Hi Guys

I have a report from a vivoactive HR user about and issue with the HR sensor

Here is part of his mail.

"I took a short run today and tried some.
During the first 2km I used the Garmin app without problems. The sensor seems active all of the time (green light on)
Then I used the Genius app. After a short time the HR did not show and the green light was off. It came back for two short times.
I also lost GPS three times, the running was in the woods surrounding our village. I normally don't loose GPS signal but it could be just bad luck.
Then again a short run with the Garmin app. I didn't wait for the HR to show but it came visible after a minute or so. No GPS problems.
And at last a short distance with the Genius app. After a short while the green lights went out and according to the watch I died of heart failure."

This was the second time he tested the app for me and in the first one he had the same results.

The strange part of the report is that the optical sensor turns off. Im my app I never disable the sensors. I enable them all when the app starts and thats it.
Another important point is that during the workout, eventually the sensor turned on, he picked the hr info and turned off again.

Based on the description seems that the sensor is not being enabled by the app, and the sporadic readings are happening when the device turns on the sensor to acquire the 24/7 hr info of the user
Or maybe the app enables the sensor but the reading for the 24/7 monitoring is incorrectly turning it off
(I'm just guessing here)

This can be a bug in the firmware, or can be a device configuration.

The core part of my app is running in other devices and I tested it in fenix3, vivoactive (non hr) and fr235 real devices, so I believe it's not an issue in my code.

I still dont have a vivoactive HR myself to test it, so I would appreciate if someone could install my app and see if the sensor simply turns off after a minute or two.

Anyone else received this kind of user complaint?

I've seen this in one of my own apps on my own wrist, and have reported it to Garmin. It seems to be va-hr specific.

We too have had this reported by users of our dwMap app and are looking forward to a fix. The recorded activity shows the behaviour too, with just a handful of HR measurements included in the saved activity when using our app.

Hi,

I have had reports as well regarding the HR not being recorded.

One user has the recording for a minute or so then nothing: https://bitbucket.org/obagot/connectiq-hict/issues/4

I hope it is a vivoactive HR issue.

Thanks!

We are working on addressing this issue. The device is not properly responding to sensor requests from ConnectIQ at this time.

Same for my apps reported from at least 5 users

Excactly the same was reported for my apps for the Vivoactive HR. I physically have a FR235 with build-in HR and everything works fine here.

I assume this is either a watch configuration issue or a Garmin firmware bug. The latter one sounds more reasonable for me as many people seem to have problems.

Still broken with 2.40 update...

Hi,

I've updated to 2.40 update yesterday, and I'm still finding that heart rate is only reported erratically within Connect-IQ apps - no heart rate for a minute or so, then working for a minute or so, then nothing for next few minutes etc.

Thanks for the info Danlance

Just an update guys.

I have reports of issues with erratic readings from the bike speed sensor and also the heart rate strap.

It seems it is not just an Optical sensor issue, but the BUG seems to affect sensors in general for CIQ apps.

Cheers,

Any informations when this issue will be resolved?

One of the device developers was working on this issue this week. I think it is corrected now, and would expect it to be part of the next device update.

This issue affects only the Optical Heart Rate sensor. If you are experiencing any repeatable issues with other sensors I recommend reporting those issues separately.
