My OpenRun Pro S810 always worked well with my old FR955.
Two weeks ago when I changed to FR965 (firmware 16.17), the earphone's BT connection with the watch during running or cycling always broke after several seconds or minutes even if I reconnected it, or even deleted the earphone and paired it again. Turning off the BT of the accompanied mobile did not help either.
Could Garmin people here or anyone tell me how to solve this problem? Thanks
