Abstract:
Systems and methods for activating select devices are described herein. More particularly, this specification relates to using structure specific service IDs (SSSIDs) when two devices that are part of a common ecosystem are deciding whether to establish a connection according to a Bluetooth protocol. The SSSID can be a unique identifier that can be included in packets that are transmitted in accordance with the standards defining the Bluetooth Low Energy (BLE) protocol. The SSSIDs can be generated and provided to select devices such that only the select devices that are in possession of the SSSID are able to communicate with each other. This advantageously eliminates spurious activation of unintended recipient devices by enabling them to ignore the packet if the SSSID is not recognized, thereby enabling the unintended recipient device to remain in a low power sleepy state.
