Garmin 235 not able to pair with Polar H10

I have seen a couple of post on this topic, but I am not able to resolve the issue with the suggestions I have seen. I have tried numerous times to pair my H10 heart rate strap (it supports both Bluetooth and Ant+) with my Garmin 235. I have literally placed the two on top of each other during the pairing process with no luck. The problem lies with the Garmin 235 as I have been able to successfully pair the H10 to multiple devices. I have reset and factory reset the 235 with no avail. ANy other suggestion or recommendations would be greatly appreciated.
  • Have you tried removing the battery from the H10 and either waiting 5 minutes to try again or just trying with a new battery? I had that issue with a Wahoo sensor and it finally paired after I left the battery out for a long time.
  • Initially my H10 would not pair with my Garmin Forerunner 235 but I found the answer. You must wear your H10 monitor, go to the Polar Beat app on your phone/device. Open the menu in the upper left corner and choose Settings. Under the heading General choose "HR Sensor". A menu opens for your H10 sensor. Enable the ANT+ option. Once that is done you the go the Garmin watch menu Settings and you can successfully pair the H10 to the Garmin 235.

    I've just followed up the procedure recommended by 2500970 and it works. I've been able to connect my Polar H10 (with the updated firmewar version) to my Forerunner 235. If your Polar H10 is older than 2019 than you need to update te firmewar via Polar Beat.

    Thank you very much for this advice. I have now managed to pair my Garmin Edge 510 with my H10.

  • Thanks. This worked for me after I updated the H10 firmware via the Polar Beats app. The ANT+ button was not showing in the Polar Beats app until I did this update. My Garmin Forerunner 45  detected the H10 strap without an issue then!

  • Not happening for me guys! My 235 simply refuses to see the external Polar H10 sensor, even after ANT+ is turned on in the Polar Beat App. I am able to bypass the issue by adding a data field from connect.garmin.com that recognizes the sensor, but I don't get real time HR zone alerts then. I have to keep looking into the watch. Very frustrating! Appreciate any insights. 

  • I followed these steps exactly. No success yet. 

  • I figured it out! I had to uninstall the data field ANT+HRM Monitor that I had installed from connectIQ Store. Once I did that, Garmin 235 magically recognized the Polar H10 HRM. All good!
