loosing communication

loosing comminication between the computer and bike sensors… i use garmin ant

Sorry your sensors and computer are losing connection! Can you try the troubleshooting steps at this link?

Make sure Garmin Connect is not working on your computer, otherwise it interferes.

Also, Ant+ lives in the same radio frequency “space” as Wi-Fi and some wireless rodents, so try to keep any device using these away from your Ant+ antenna/dongle.

I just run a long active USB cable with the Ant+ dongle just next to my bike.
