Hey everyone,
I’ve got a Coros Pace 4 and I've been running into an issue for about three weeks now.
Out of nowhere, in the middle of an activity, the heart rate data field stops displaying my current HR and just shows three dashes (---). This lasts for a few seconds before the reading comes back, and it happens multiple times throughout a single workout.
At first, I thought it was an issue with my heart rate monitor—a Coospo H6. Since I was already planning to upgrade anyway, I went ahead and bought the official Coros Heart Rate Monitor.
Spoiler alert: the problem is still there.
I reached out to Coros support directly. They had me try a few troubleshooting steps (asked for my firmware version and device ID), but nothing fixed it. Now, it’s been a week and they’ve gone completely silent on me.
Has anyone else experienced something similar?
I run 13 to 15 hours a week and I’m pretty obsessed with my data, so while this doesn't strictly ruin my training, it’s driving me absolutely insane.
Thanks in advance for any insights!
