Is there a way for the bluetooth peripheral device to remain connected to iOS even after the app which was used to pair with it has been swipe killed by the user? I have -

  1. enabled Background Modes (Uses Bluetooth LE Accessory)
  2. given all the relevant permissions (Background refresh)
  3. implemented state preservation and restoration.
  4. properly handled Connection Events with proper options (CBConnectPeripheralOptionNotifyOnConnectionKey and CBConnectPeripheralOptionNotifyOnDisconnectionKey)

e.g Fitbit shows as connected in bluetooth settings even after the app has been swipe killed by the user.

It cannot stay connected, or relaunched even with state restoration if it has been swipe killed by the user. Swipe kill is considered a terminal action by the user indicating they no longer wish that app to be running.

Once swipe killed, they need to relaunch the app themselves for the Bluetooth functionality to work again.
