I did a small run with my HRM Pro, and it is connected to the watch. When I looked at the Heart Rate it was a bit strange as it didn't register the HR ramp-up of a sprint that well, which it would normally do.
Looking at the fit file afterward, the HRM strap is listed under device_info, but is not chosen as HR source.
I thought it was maybe the strap dying, but using another watch with older firmware, it took the HRM Pro as source in another test.
Anyone else seen this behavior?
The simplest way to see in real-time whether your HRM-Pro is connected or not, is adding one of the RD fields on the main data screen (or on another one). When HRM-Pro is not connected, it remains blank…
It actually can.
It can but it most often is not. Let's not suddenly pretend that OHR is more precise than chest strap, when in every post related to inaccurate OHR it is always recommended to…
I do not quite understand why would you want to disable the OHR
1) I do not want that the watch decides whether OHR vs strap is the correct, because OHR could go nuts providing 40 BPM higher…
The simplest way to see in real-time whether your HRM-Pro is connected or not, is adding one of the RD fields on the main data screen (or on another one). When HRM-Pro is not connected, it remains blank (resp. with dashes). There is a value only when HRM-Pro is connected. Very easy to see the difference, even if a data field with small font is used:
Alternatively, you can scroll down and see whether there are the two additional RD screens - they are also present only when the strap is properly connected.
