After a ride of around 100 km, I took an 1 hour pause with Edge 840 today. After the pause, it refused to connect to my speed sensor, my HRMPro+, and my powermeter. It was able to connect to the speed sensor and the powermeter after a while, but refused to connect to the HRMPro+ until the end of my ride.
My Fenix 6 had no trouble connecting to all sensors at any time.
Did someone experience something similar with their Edge device and has a solution for that behavior?
