My Edge 520 drops my heart rate and cadence sensor randomly, but generally every few miles (it almost never makes it 10 miles without dropping). They will both simultaneously just display the --- line. If I reboot the 520 they are re-connected, but you can imagine its annoying to do this multiple times every ride.
Curiously the speed sensor continues, although perhaps thats the internal GPS, not the the actual sensor, I really don't know.
Any suggestions? It has the latest software. Should I try the factory reset? Should I try reloading the software (and how would I actually do that)?
Or is this some known hardware issue that, like a shorting out antennae, that I can never fix and its just time to get a new computer?
I've seen lots of posts about losing cadence and speed sensor connections, but not this combination (!).
Thanks to anyone who has input in advance!!!
