Re: Polar H7 heart sensor & Healthkit

Just to clarify: as written before, LapTimer does not trigger health data recording or stores data. This process is completely independent from LapTimer and triggered just by wearing the H7 & friends (and enabling Health Kit recordings). I repeat this to make sure we are on the same page for trouble shooting.

Given that, there are two potential issues.

1) Data you see in HK does not match the time ranges on track.
2) LapTimer does not correctly map timestamps of measurements in Health Kit to lap time ranges recorded by LapTimer.

To troubleshoot the later, a debugging enabled LapTimer version is required - I can provide this during beta phases only.
So let us check #1 first. To do this, please select any single lap from Lap List you assume heath data should have been recorded by the H7 / Health Kit. Create a snapshot showing the time of day and lap time of this lap. Next, start the Health app and select the chart showing heart rates. Zoom / scroll to the lap's time range and create a snapshot showing the time range and data collected. For privacy reasons, it is probably better to send these snapshots to Harry@gps-laptimer.de

Yes, it is very clear that LapTimer reads the Health data.

Thinking iOS 11 might help the situation, I installed 11.0.3 and now -- no matter how I configure it -- Health is not receiving the heart rate data. Under iOS 10, Health Sources Devices listed the iPhone and the H7. Under iOS 11, only the iPhone appears.

If and when I get Health recording heart rate data, I will try HLT again.

Dear all, I wish a happy new year 2018 !

I just bought a Polar H7 heart rate belt. As the others, I have trouble figuring out how I should use it to get the heart rate data on the overlay video.

I am able to get an overlay of the heart rate but it sticks to "0" when i have the polar belt on. I'm wondering if the use of a iWatch is necessary ?

Anyways, do you have any news on that topic ?

Regards,

Axel

Setup your H7 to feed data into Apple HealthKit. In care LapTimer finds data in HK for the time of a lap, it will pull that data and overlay it. LapTimer GP (and iOS) required.

I've attended seven track days this year and have been able to get HLT to work with the Polar H7 about one third of the sessions.

Here's my routine:

1. Start recording on the Polar watch.
2. Open Polar Beat | Settings | Apple Health | Connect
3. Continuing in Polar Beat go to Training | Start (heart rate is shown)
4. Open Apple Health | Sources | Lap timer | Heart Rate Data | On
5. Continuing in Apple Health | Sources | Polar Beat | Heart Rate | On
6. Open HLT and use as usual
7. Heart rate data show up in HLT about a third of the time

Note HLT, Polar Beat and Apple Health are all open at the same time

I am wondering if after a session I need to stop heart rate recording before HLT can access it?

Is HLT reading the heart rate data in real time or after a session is complete?

Using HLT 21.2, iOS 11.2, iPhone 6.

Heart rates are retrieved from Health Kit when it is displayed. Other than GPS etc Sensor data, health data is not recorded by LapTimer. So to check were the problem is, goto Health Kit and verify you find heart beats for the time you have been on track.
