Waking Up the CoreUpdated a year ago
When not in an active session, the Core goes to sleep after 2 minutes and needs to be woken up with a shake/flip motion (e.g. like flipping a coin from heads-to-tails).
After the wakeup, if a session isn't started within 2 minutes, the Core will go to sleep and need to be woken up again to be able to press START for the session.
