Garmin HRM 600
The Garmin HRM 600 currently has a severe issue: it transmits RR intervals (the time between heartbeats) too frequently. This distorts the signal and leads to a total sum of RR intervals that is noticeably longer than the actual recording duration. As a result, the data is not suitable for reliable HRV analysis.
In addition, the recordings may contain a higher number of artifacts (implausible RR intervals) than expected.
We recommend installing the latest firmware update to check whether the issue has been resolved. If the problem persists, using a different heart rate monitor is advisable.
You may notice that other apps appear to work fine with the HRM 600. This is often because they do not validate the quality of the recorded data. However, if the input data is inaccurate, any derived results will be unreliable as well. Therefore, apps that do not flag invalid data should be interpreted with caution.
How to tell if a Heart Rate Monitor is supported by Breath Ball?
In general, any Heart Rate Monitor that that supports the standardized Bluetooth Heart Rate Profile should work. But to be sure, there are two ways to verify:
- Try to connect to a Heart Rate Monitor in Breath Ball.
If the connection fails, there will be an error. If it succeeds, the heart rate monitor icon at the top right corner will change. - Using a generic Bluetooth LE scanner app:
If a Bluetooth LE scanner app displays “Heart Rate Service” (Service ID: 0x180D), for a given Heart Rate Monitor, then it should work with Breath Ball.
