To elaborate on shubhams's answer:

Unfortunately there is no way for Android devices to act as a peripheral. He can creates GATT servers, services and charachteristics but there is no way to make the advertising. (https://stackoverflow.com/a/18020153/3061383)

Since Android does not (yet) support advertising no other BLE device is able to initiate a connection to an Android device. As of now the Android device must initiate the connection.
