I’ve had a 2s for a few years now. I’d not ridden my road bike for a while and when I went out recently it wasn’t connected, assumed it was the battery so changed it. It kept intermittently connecting and dropping out. I changed the battery again in case it was a dud, removed the sensor then tried reconnecting it. Now it won’t connect. It was flashing 7 times suggesting a software update, but it wasn’t connected. So I removed the plug and reinserted it, (wiped it out checking the prongs) that solved the 7 flashes, now it’s on 2 flashes and just won’t connect. Tried it on edge 1030 and fenix 6!
Any ideas? Or is all lost! :(
