A method and system for Bluetooth (BT) delayed acknowledgment is presented. Aspects of the system may include an initiator device, such as a WLAN access point (AP), which enables transmission of a protocol data unit, such as a BlockAckReq frame, to a responder device, such as a Smartphone, via a first network, for example a WLAN. The Smartphone may be equipped with capabilities that enable communication via WLAN and Bluetooth networks. The AP may wait to receive a response protocol data unit, such as a BlockAck frame, via the first network (WLAN) for a response time duration. The response time duration may be based on the communication slot time duration for communication by the Smartphone on a second network, for example a BT piconet. The communication slot time duration may correspond to the time duration for a BT slot.
