Unfortunately, the Android BLE API only supports half of the standard, as Android devices cannot be placed in peripheral mode. This is something Apple released on day 1, and it's slightly infuriating when creating cross-platform applications. There is no good, non-hacky way to do local radio comms between iOS and Android, and it stinks. Here's hoping Kit Kat rolls out with full BLE support.
