HRM Pro losing connection during workout

Hello!

In my recent two runs I've experienced that during the run my watch stops showing my heart rate and all I can see is "--". Hovewer the battery status for the HRM shows "OK" in the activity summary afterwards. The overall blackout lasts for about 10s- 2m.

I am using Fenix 6X Sapphire with HRM Pro.

Software versions.

-F6X- 23.10

-HRM Pro - 8.8

Could it be somehow related to software bug or rather a hardware issue?

You guys might want to look at the sensors and accessories forum....

Personally I've never had connectivity problems between my 6X Pro Solar and HRM-PRO on any firmware. I'm running the latest firmware on both.

Unfortunately I can't be as positive about Bluetooth connections from strap to Zwift on my tablet, but that could be a tablet issue or Zwift. I've not used Zwift on my tablet since May and I haven't bothered to dig deeper.
