MK2 Does Not Show Heart Rate

I have MK2 and I am a diver. I use the Dive app to show my dive details and for some reason the heart rate will not be shown in the app. My MK1 used to show the heart rate in the dive app.

Please help

  • For me it shows Avg and Max Heart Rate under Log Detail -> Advanced Details. If I click on Dive Timeline I get a graph for the Heart Rate. However, I only get data in the graph if I've used the wrist heart rate or if my chest strap has ANT+ connection (i.e. just at the end when I surface). For chest strap data downloaded after the dive I need to go to connect.garmin.com, which will show a graph for all the downloaded heart rate data.
