i m very new with external sensor and I m facing some kind of issue with my hrm-pro. The sensor is linked correctly to both my fenix6 watch and my garmin connect app. However I dont see any live data coming on my watch (I took it off my arm to make sure the info is not coming from the builtin sensor) nor on the garmin connect app.
I was wondering whether the hrm is supposed to send live data to be read directly in live on the watch/app or if the hrm is only monitoring the activity and then transfer the data after the sport session is completed.
any advice ?
thanks in advance
