Dear Kevin, thanks a lot for getting back so quickly & your detailed response! The problem I'm trying to solve is to reliable sync data from a BLE peripheral in Background over a longer period of time — either during the day or the night — between our user opening the App. However, once the app is killed, the task is no longer scheduled in the Background until the App is reopened, the Task resubmitted & re-scheduled. So I'm looking for a way to rerun the Task even though the App was killed. Is there any way to launch the App into Background "later" as you mentioned other than having to open the App again?
