[WIP] advertise as iBeacon

In order to wake iPhones, the android phones need to act as an iBeacon.

Given the iBeacon specs, we're trying to match the following bytes:

0x02011a1aff4c000215c8c299fb9ccd4322a1e6790099fe62c600000000c50000000000000000000000000000000000000000000000000000000000000000

Which matches the specs with the UUID of c8c299fb-9ccd-4322-a1e6-790099fe62c6 and a txPower of -59 (0xc5). I have not succeeded at doing this yet. If succesfull, the advertisement should pop-up in one of the Beacon locator apps from android, windows or apple (just look in the stores).
