The first electronic device 101 and the second electronic device 102 in the environment 100 may be audio sink devices such as earbuds or earphones. For example, the first electronic device 101 and the second electronic device 102 may be configured as a pair. However, it is not limited thereto. For example, each of the first electronic device 101 and the second electronic device 102 may receive data on audio from the third electronic device 103 and output, based on the data, the audio through a speaker of each of the first electronic device 101 and the second electronic device 102. For example, the first electronic device 101 and the second external electronic device 202 may receive a request from the third electronic device 103 and transmit, in response to the above request, data on audio obtained through the microphone of the first electronic device 101 and the microphone of the second electronic device 102 to the third electronic device 103, respectively. For example, the data may be usable to play the audio in the third electronic device 103. For example, each of the first electronic device 101 and the second electronic device 102 may be referred to as a peripheral device, a secondary device, or a sub device.
For example, each of the first electronic device 101 and the second electronic device 102 may be stored in the fourth electronic device 104. For example, each of the first electronic device 101 and the second electronic device 102 may include a rechargeable battery. For example, each of the first electronic device 101 and the second electronic device 102 may obtain power to charge the battery from the fourth electronic device 104. For example, each of the first electronic device 101 and the second electronic device 102 may obtain the power from the fourth electronic device 104, while each of the first electronic device 101 and the second electronic device 102 is stored in the fourth electronic device 104.
The third electronic device 103 in the environment 100 may be an audio source device such as a smartphone, a laptop computer, a desktop computer, or a tablet PC. For example, the third electronic device 103 may transmit data on audio being played in the third electronic device 103 to each of the first electronic device 101 and the second electronic device 102. For example, the data may be usable within each of the first electronic device 101 and the second electronic device 102 to output the audio from each of the first electronic device 101 and the second electronic device 102. In an embodiment, the third electronic device 103 may be referred to as a central device, a primary device, or a main device.
The fourth electronic device 104 in the environment 100 may be a device for providing power to each of the first electronic device 101 and the second electronic device 102. For example, the fourth electronic device 104 may provide a space for storing each of the first electronic device 101 and the second electronic device 102. For example, the fourth electronic device 104 may provide a first state (e.g., a case or housing of the fourth electronic device 104 is open) in which at least a portion of the first electronic device 101 and at least a portion of the second electronic device 102 stored in the space are exposed. For example, the fourth electronic device 104 may provide a second state (e.g., the case or housing of the fourth electronic device 104 is closed) in which the first electronic device 101 and the second electronic device 102 stored in the space are covered. For example, the fourth electronic device 104 may provide a third state in which the first electronic device 101 and the second electronic device 102 are spaced apart from the space. However, it is not limited thereto. For example, the fourth electronic device 104 may be referred to as a cradle.
For example, the first electronic device 101 and the third electronic device 103 may establish a connection 110 between the first electronic device 101 and the third electronic device 103 to provide an audio service. For example, the second electronic device 102 and the third electronic device 103 may establish a connection 120 between the second electronic device 102 and the third electronic device 103 to provide the audio service. For example, for the audio service, data provided from the third electronic device 103 to the first electronic device 101 may be synchronized with data provided from the third electronic device 103 to the second electronic device 102. For example, on a condition that the connection 110 and the connection 120 are established, the third electronic device 103 may provide the data to the first electronic device 101 and the second electronic device 102 for the synchronization.
For example, each of the first electronic device 101 and the second electronic device 102 may perform or execute an advertising process to establish each the connection 110 and the connection 120. For example, the first electronic device 101 may broadcast at least one advertising protocol data unit (PDU) of the first electronic device 101 within an advertising process of the first electronic device 101. For example, the third electronic device 103 may establish the connection 110 based on receiving the at least one advertising PDU of the first electronic device 101, using a scan window corresponding to a part of a scan interval of the third electronic device 103. For example, the second electronic device 102 may broadcast at least one advertising PDU of the second electronic device 102 within an advertising process of the second electronic device 102. For example, the third electronic device 103 may establish the connection 120 based on receiving the at least one advertising PDU of the second electronic device 102, using the scan window corresponding to a part of the scan interval of the third electronic device 103.
For example, in case that performing the advertising process of the first electronic device 101 is independent of performing the advertising process of the second electronic device 102, since time resources of the third electronic device 103 used to receive each of the at least one advertising PDU of the first electronic device 101 and the at least one advertising PDU of the second electronic device 102 are parts of the scan interval, a probability that both an establishment of the connection 110 and an establishment of the connection 120 are completed within a certain period of time (e.g., about 1 second) may be less than about 25%. For example, when performing the advertising process of the first electronic device 101 is independent of performing the advertising process of the second electronic device 102, quality or a responsiveness of the audio service may be reduced.
For example, the first electronic device 101 may perform the advertising process of the first electronic device 101 synchronized with the advertising process of the second electronic device 102 to enhance the quality or the responsiveness. For example, the advertising process of the first electronic device 101 synchronized with the advertising process of the second electronic device 102 may indicate the advertising process of the first electronic device 101 identified or obtained based on the advertising process of the second electronic device 102 or the advertising process of the second electronic device 102 identified or obtained based on the advertising process of the first electronic device 101. For example, the advertising process of the first electronic device 101 synchronized with the advertising process of the second electronic device 102 may indicate not only the advertising process of the first electronic device 101 in a time interval completely overlapped with a time interval of the advertising process of the second electronic device 102 but also the advertising process of the first electronic device 101 in a time interval partially overlapped with the time interval of the advertising process of the second electronic device 102. However, it is not limited thereto.
For example, a connection 130 between the first electronic device 101 and the second electronic device 102 may be used for the synchronization between the advertising process of the first electronic device 101 and the advertising process of the second electronic device 102. For example, a connection 140 between the first electronic device 101 and the fourth electronic device 104 and a connection 150 between the second electronic device 102 and the fourth electronic device 104 may be used for the synchronization between the advertising process of the first electronic device 101 and the advertising process of the second electronic device 102.
For example, each of the first electronic device 101 and the second electronic device 102 may include components for the synchronization between the advertising process of the first electronic device 101 and the advertising process of the second electronic device 102. The components may be illustrated in

For example, the operational coupling of the processor 210 with a component may indicate that the processor 210 controls the component. For example, the operational coupling of the processor 210 with the component may indicate that the processor 210 is connected to the component. For example, the connection may include a direct connection between the processor 210 and the component. For example, the connection may include a connection between the processor 210 and the component through another component. However, it is not limited thereto.
For example, each of the communication circuits 220 of the first electronic device 101 and the second electronic device 102 may be used for the synchronization between the advertising process of the first electronic device 101 and the advertising process of the second electronic device 102. For example, the communication circuit 220 may include a communication circuit for Bluetooth. For example, the communication circuit 220 may include a communication circuit for legacy Bluetooth (or classic Bluetooth) and Bluetooth low energy (BLE). For example, the communication circuit 220 may include a communication circuit for power line communication (PLC). For example, in case that the communication circuit 220 includes the communication circuit for the PLC, the communication circuit 220 may be used to obtain power. Hence, the communication circuit 220 is not restricted to a particular technology such as Bluetooth or PLC.
For example, the speaker 230 may be used to output audio corresponding to data received from third electronic device 103.
For example, the microphone 240 may be used to obtain audio. Data on the audio obtained through the microphone 240 may be transmitted to the third electronic device 103. However, it is not limited thereto.
For example, the sensor 250 may be used to identify a state of the first electronic device 101 (or the second electronic device 102) or a state of an environment including the first electronic device 101 (or the second electronic device 120). For example, the sensor 250 may be used to identify whether an external object is located around the first electronic device 101 (or the second electronic device 102). For example, the sensor 250 may be used to obtain data indicating whether the external object is located within a specified distance from the first electronic device 101 (or the second electronic device 102). For example, the sensor 250 may include a proximity sensor. However, it is not limited thereto.

For example, the second electronic device 102 may transmit the at least one signal to the fourth electronic device 104 through the connection 150 with the fourth electronic device 104 established before identification in operation 301. For example, the fourth electronic device 104 may transmit the at least one signal received from the second electronic device 102 to the first electronic device 101 through the connection 140. For example, the connection 140 may be established in response to the reception of the at least one signal from the fourth electronic device 104, established before the identification in operation 301, or established before receiving the at least one signal in the fourth electronic device 104 after the identification in operation 301.

In operation 305, the first electronic device 101 may synchronize the advertising process of the first electronic device 101 with the advertising process of the second electronic device 102 based on the at least one signal.
For example, the first electronic device 101 may synchronize the advertising process of the first electronic device 101 with the advertising process of the second electronic device 102 based on information indicated by the at least one signal.

For example, the first electronic device 101 may identify the time resources by identifying the start timing of the advertising process of the first electronic device 101 based on the start timing of the advertising process of the second electronic device 102. For example, the first electronic device 101 may identify the time resources based on identifying the start timing of the advertising process of the first electronic device 101 as a timing within a specified time from the start timing of the advertising process of the second electronic device 102. For example, the specified time may be to reduce the time for the third electronic device 103 to scan the first electronic device 101 and the second electronic device 102. For example, the start timing of the advertising process of the first electronic device 101 may be a timing after another specified time from the start timing of the advertising process of the second electronic device 102. For example, the other specified time may be shorter than the specified time. For example, the other specified time may be for a transmission timing of the first advertising protocol data unit (PDU) of the first electronic device 101 to be broadcasted within the advertising process of the first electronic device 101 not to overlap a transmission timing of the first advertising PDU of the second electronic device 102 to be broadcasted within the advertising process of the second electronic device 102. For example, the other specified time may be for the transmission timing of the first advertising PDU of the first electronic device 101 spaced apart from the transmission timing of the first advertising PDU of the second electronic device 102. For example, the first electronic device 101 may identify the transmission timing of the first advertising PDU of the first electronic device 101, based on least a part of the transmission timing of the first advertising PDU of the second electronic device 102 and a transmission timing of a connection request from the third electronic device 103 to the second electronic device 102. For example, the first electronic device 101 may identify the time resources, based on identifying a transmission timing of the first advertising PDU of the first electronic device 101 to be broadcasted within the advertising process of the first electronic device 101 in a time interval between the transmission timings of the first advertising PDU of the second electronic device 102 and the second advertising PDU of the second electronic device 102, to be broadcasted within the advertising process of the second electronic device 102.
For example, the first electronic device 101 may identify the time resources based on identifying length of the advertising interval of the advertising process of the first electronic device 101as length corresponding to the length of the advertising interval of the advertising process of the second electronic device 102.
For example, the first electronic device 101 may identify the time resources based on identifying the advertising interval of the advertising process of the first electronic device 101 as a time interval before the start timing of the other advertising process of the second electronic device 102 (e.g., an advertising process of the second electronic device 102 after the advertising process of the second electronic device 102). For example, the first electronic device 101 may identify the time resources, based on identifying the advertising interval of the advertising process of the first electronic device based on a delay time interval between the advertising process of the second electronic device 102 and the other advertising process of the second electronic device 102, indicated by the at least one signal.
For example, the first electronic device 101 may identify the time resources by identifying a transmission timing of each of the first advertising protocol data units (PDUs) (e.g., ADV_EXT_IND) of the first electronic device 101 and a transmission timing of the second advertising PDU (e.g., AUX_ADV_IND) of the first electronic device 101 indicated by each of the first advertising PDUs, based on a transmission timing of each of the first advertising PDUs (e.g., ADV_EXT_IND) of the second electronic device 102 and a transmission timing of the second advertising PDU (e.g., AUX_ADV_IND) of the second electronic device 102 indicated by each of the first advertising PDUs of the second electronic device 102. For example, each of the first advertising PDUs of the second electronic device 102 may indicate a PDU to be broadcasted within the advertising process of the second electronic device 102. For example, the second advertising PDU of the second electronic device 102 may indicate a PDU to be broadcasted within the advertising process of the second electronic device 102. For example, each of the first advertising PDUs of the first electronic device 101 may indicate a PDU to be broadcasted within the advertising process of the first electronic device 101. For example, the second advertising PDU of the first electronic device 101 may indicate a PDU to be broadcasted within the advertising process of the first electronic device 101.
For example, the first advertising PDUs of the first electronic device 101 may be broadcasted from the first electronic device 101 before the second advertising PDU of the second electronic device 102 is broadcasted. For example, the second advertising PDU of the first electronic device 101 may be broadcasted within a specified time from the transmission timing when the second advertising PDU of the second electronic device 102 is broadcasted. For example, the second advertising PDU of the first electronic device 101 may be broadcasted after the second advertising PDU of the second electronic device 102 is broadcasted, and before the other advertising process of the second electronic device 102 is initiated. For example, the second advertising PDU of the first electronic device 101 may be broadcasted based on a transmission timing of the second advertising PDU of the second electronic device 102 and the transmission timing of a connection request transmitted from the third electronic device 103 in response to the second advertising PDU of the second electronic device 102. However, it is not limited thereto.
