I've had a Garmin Edge 810 for a number of years and a number of iPhones over the same period. On switching on the Edge and opening the app, both tell me they're are connected to each other (via Bluetooth). The phone's Bluetooth settings confirm this. I go for a ride, then save the ride and the Edge tries but fails to successfully sync the ride to the app. Repeatedly turning on/off of the phone, the Edge and the app, unpairing and re-pairing the Edge, and then trying again fails to solve the problem.
The things is, it's not a new problem. Its always been like this - Initially, and for a few years, following an update of the app, uploading went smoothly for a while but then another update comes along and it stops working. For a while it yo-yo'd between working and not working with successive updates but the last 4 updates have failed to get the app to accept data from the Edge. I really have no idea why, if the app and Edge both report a Bluetooth connection to each other, the ride data just won't transfer.
What, if anything, can I do about it?
Would a newer Edge behave better with the app? I really only want mapping, routing and a few ride metrics. None of the newer features (and there are loads) attract me.
Are there any other apps that can upload data from the Edge (that don't require Garmin Connect app to act as middleman, e.g. Strava)?
Should I get a Wahoo or something else?
Thanks for any help (or just sympathy)
