Not receiving BLE events in background

Hi!

Do I have to add anything to the app to indicate iOS that BLE events must be delivered to it while backgrounded? I declared the UIBackgroundModes / bluetooth-central in the info.plist file, so in theory I should be able to receive the events.

1. The app scans for the BLE accessory and connects to it. Connection is reestablished automatically if the didDisconnect is received.
2. Go back to the home screen.
3. No callbacks while the app is in the background.
4. Bring the app back to foreground, and the didConnect, didDiscover and other callbacks are immediately called.

Thanks in advance,
Andras
