I got a 2nd-hand 310xt recently (having had two before) and it transferred its data to Garmin Connect via ANT+ no problem. Bring the watch close to my WIndows 10 laptop and bingo, the message on the watch showed it transferring data and it worked fine.
Now it seems to have "just stopped" doing this. I haven't deliberately done anything. It just doesn't show anything on the watch to show any activity. Windows 10 shows no problem with seeing the ANT+ stick, even after I deleted the device and then put it back in, when it reinstalled it no problem.
Anyone know why this might mysteriously have happened?
Thanks,
Ian Watson
