Apple Watch Ultra + Polar H10 continuously disconnects via bluetooth, any ideas?

I want to record my heart rate on runs/hikes using my just Apple Watch Ultra and Polar H10. The goal is to pair/connect the H10 to the Apple Watch Ultra via Bluetooth (as a ‘health device,’) and then use it with the Fitness app.


The problem I’m having is the watch will not pull heart rate from the H10, instead, it defaults to heart rate pulled from the watch every time. 


When I attempt to connect via bluetooth it briefly tells me its connected, then immediately says not connected. 


The watch will pull HR from the Polar when I run with my iPhone + use the Polar app, but I want to be able to run using just the strap and watch. I’ve tried resetting (both the watch and hard resetting the H10), repairing, changing battery, restarting, etc with no luck.


Has anyone else experience this issue, any ideas?

I have the same issue with my awu2 and H10… I have been in contact with Apple support but they say it’s not an issue on there end. Awaiting a reply from Polar support. This is very frustrating as I train via HR.

Simple answer is you cannot connect H10 to Watch

This is incorrect. The Polar H10 is compatible with Apple Watch.

Why it keeps disconnecting, I cannot say. The solar H10 may need a firmware update.
