Cant connect Bluetooth HR monitor

Star III

Can't connect my Polar H9 HR monitor to Zenfone 10 via BT.

It connects, asks for pairing (and allow access to contacts and call history, lol), then after few seconds gives message "Couldn't pair with because of an incorrect PIN or passkey".

I see it in Strava sensor list, but it simply doesn't connect.


I changed battery for H9, rebooted phone, but nothing changes. It keeps connecting in Strava with no results and I don't see it in my BT device list after initial failed pairing.

Worked fine on my previous cheap phone.

Seriously? How can I get basic BT functionality on this phone? BT is working, as I can connect CO2 sensor and headphones, but not this HR belt.

Please advice.
