Abstract
The present description provides methods, computer program products, and systems for saving power in Wi-Fi devices utilizing Bluetooth. A Wi-Fi radio transitions to deep sleep mode from active mode while a Bluetooth radio remains active. An active Wi-Fi connection to the access point can be maintained by the station while in deep sleep mode as needed to prevent being disassociated. Responsive to the indication of data packets waiting at the access point, sent over the Bluetooth radio, the Wi-Fi radio at the station can be transitioned from the deep sleep mode to the active mode. A notification of active mode is sent to the access point currently associated with the Wi-Fi radio so that packets can be forwarded.
