For example, the same as the watch would do when going about daily life (albeit in this case without wearing the watch, just the HRM-Pro by itself)?
If so, how/when does this data get sync'd back to Garmin Connect and then presumably any Garmin watch via TrueUp? ie. is there a direct BLE connection from phone to strap, or is it the next time the strap is connected to a Garmin watch, both, something else?
Thanks.
