Forerunner 35 Unable to Sync

Former Member over 6 years ago

I have a new Forerunner 35 that I bought late Jan 2019. Didnt have any problems with syncing to my GC Android via Bluetooth until maybe the past week where it would just sync eternally but make no progress. It syncs fine via Garmin Express USB to laptop.

I use it for steps and also cycle every day.

Is this an issue with the GC app or is ~1 month of cycling too much data in the watch?
Should I delete the saved data in the watch? Which folder is safe to delete and if I were to sync after deleting does it

remove all data previously saved on GC that now no longer exist on the watch or
does my watch recopies all old data from GC or
only new data from my watch is transferred to GC with otherwise no deletion of older data on GC and no transfer of older data from GC to watch?

Thanks!

Are you running v 4.15 of Gramin Connect?. There appears to be an issue re synching with this version. See the thread " [h=2]Syncronization of activities didn't finished after Update Garmin Connect App to 4.15[/h] "

Normally, only new activities are sent to Garmin Connect. Once it succeeds, the synced activities won't be resynced to Garmin Connect even if they still exist on the watch.
Activities in garmin connect are there until you delete them in garmin connect. Deleting them on the watch won't affect any data in garmin connect.
Activities deleted from the watch are not synced back from garmin connect.

I followed the instructions and uninstalled 4.15 and reinstallled 4.13 via APK and its still forever syncing. Is this an issue for everyone on a Huawei

So I called Garmin and finally got my syncing issue between my watch {645M} and Android {Pixel 2} fixed. Essentially I had some corrupt files. So we went in on explorer (I use Windows) found the device, clicked on primary/garmin and deleted the apps and the activity folders did a long reset on the watch and everything's fine now.
