I am not sure if I understand you correctly, could you please elaborate more? What kind of data are you talking about? If you are talking about a connection and the master device is the client, then you would need to notify data to it from a connected server. If the the master/central device is not in a connection, then it can receive advertising data from a peripheral device which is broadcasting advertising packets.
