description This disclosure describes techniques for allowing a wireless device and a peripheral device to enter a sleep state while maintaining an active WLAN link between the wireless device and the peripheral device. In some implementations, the wireless device operates as a STA associated with a WLAN while also operating as a softAP. The wireless device selects a sleep state beacon interval based on a handover request, and obtains a next sleep state TBTT based on the sleep state beacon interval and a TSF value of the wireless device. The wireless device sends a message to the peripheral device over the Bluetooth connection, the message indicating the next sleep state TBTT and the sleep state beacon interval, and transmits one or more beacon frames to the peripheral device over the WLAN link during the sleep state based on the next sleep state TBTT and the sleep state beacon interval.
