Abstract
The described embodiments include a system for communicating between electronic devices. During operation, a receiving electronic device receives a data channel protocol data unit (PDU) in a link layer of a Bluetooth Low Energy (BTLE) protocol stack. The receiving electronic device then reads a field in a header of the data channel PDU to determine if the header indicates that a payload of the data channel PDU contains audio data. When the header indicates that the payload of the data channel PDU contains audio data, the receiving electronic device is configured to send the audio data from the payload to an audio layer in the BTLE protocol stack for processing.
