As described previously, when the user wants to utilize the Bluetooth device set 102 to playback audio data transmitted from the Bluetooth host device 110 by adopting the BLE Audio technology, the Bluetooth host device 110 should be paired with respective member devices in the Bluetooth device set 102 in advance. In this situation, as described above, the processing circuit 117 may generate a Bluetooth inquiry request containing the device information of the Bluetooth host device 110 (e.g., a Bluetooth device address of the Bluetooth host device 110), and may utilize the host-side communication circuit 111 to transmit the Bluetooth inquiry request to other nearby Bluetooth devices, and then wait for responses from the member devices of the Bluetooth device set 102.
Alternatively, the processing circuit 117 may control the host-side communication circuit 111 to operate in the aforementioned predetermined receiving mode at an appropriate time according to the user's manipulation, or based on the default operating instructions of the internal programs.
On the other hand, all member devices in the Bluetooth device set 102 may enter a predetermined transmitting mode at an appropriate time according to the user's manipulation, or based on the default operating instructions of the internal programs, or may operate in the predetermined transmitting mode after receiving the Bluetooth inquiry request generated by the Bluetooth host device 110.
The first member device 120 may perform the operation 402 of
