Just picked up a Vivosmart yesterday and set it up with my iPhone 6s Plus.
With my old Fitbit Charge HR, I could set it so the Fitbit would only connect to my iPhone when the Fitbit app was open. I can't seem to get the Garmin device to disconnect, however, without completely unpairing it? When it stays connected, it kills the battery on both my phone and the Garmin.
Can this be set up like the Fitbit to only connect and sync data when the Garmin app is opened, and then disconnect when the app is closed?
