Make Samsung Android device advertise as an iBeacon

Solution
EDIT: this answer is about older Samsung phones with Android 4.2. Samsung devices with Android 5.0+ can advertise beacons successfully.
Unfortunately, @reTs and @duncan-c are right (+1 for each of them). The Samsung BLE SDK cannot send out real BLE advertisements as is required for iBeacons.
I was holding out hope because their documentation says "allowing applications to create and advertise Bluetooth smart services and characteristics". I wrote an app to prove whether this actually worked, and learned that their documentation is simply misleading. The Samsung BLE SDK will not make Samsung devices transmit advertisements over the radio.

Problem
Has anybody used Samsung's Bluetooth LE APIs to make a Samsung Android device advertise as an iBeacon? This should be possible, but I do not have access to a device to try it. If anybody has used it to make a Samsung Android device advertise as any other Bluetooth LE peripheral, I would like to know that, too. EDIT: This is now possible on Android L. See here.
