Core Bluetooth 101 Session 703 WWDC 2012

Hello, A while ago (last year) I watched this presentation on the Apple Developer website to get a better understanding of Bluetooth Low Energy and I really liked it. Now I searched for it a couple of times and I could not find it. I only stored the following link: https://developer.apple.com/videos/play/wwdc2012/703/ It seems to be gone. I managed to find the slides, but not the full presentation. Any suggestions where to find it or why it was removed? Thanks.
