Patent ID: 8849202

Claim:
A method for communicating between electronic devices, comprising: in a receiving electronic device, receiving a data channel protocol data unit (PDU) in a link layer of a Bluetooth Low Energy (BTLE) protocol stack; reading 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, sending the audio data from the payload to an audio layer in the BTLE protocol stack for processing; receiving a data channel PDU in a multiplexing layer of the Bluetooth Low Energy (BTLE) protocol stack; upon determining that the data channel PDU is a configuration packet that includes information that one or more applications use in updating a configuration of at least one of the audio layer, an audio data processor in an audio subsystem, or an audio transducer, sending information from the data channel PDU to the one or more applications; and in the one or more applications, configuring at least one of the audio layer, the audio data processor in an audio subsystem, or the audio transducer in accordance with the information from the data channel PDU.
