In practice, the Bluetooth host device 110 and other member devices in the Bluetooth device set 102 (e.g., the third member device 140) may establish connections according to the aforementioned interaction between the Bluetooth host device 110 and the second member device 130 to respectively generate required cypher keys for conducting subsequent Bluetooth data transmissions between both parties.
In the embodiments where both the Bluetooth host device 110 and the second member device 130 support the BLE Audio technology, the Bluetooth host device 110 may adopt the BLE Audio technology to transmit audio data to the second member device 130, and the Bluetooth host device 110 can utilize the Low Complexity Communication Codec (LC3) to encode the audio data. As a result, it not only reduces the power consumption of the Bluetooth host device 110 and the second member device 130 to thereby extend the serving time of the Bluetooth host device 110 and the second member device 130, but also effectively improves the overall quality of the audio playback operations.
