Claim 13:
14. The auxiliary Bluetooth circuit (120) of claim 12, wherein the second control circuit (127) is further arranged to operably transmit the signal reception quality indicator to the main Bluetooth circuit (110) through the second Bluetooth communication circuit (121), for the main Bluetooth circuit (110) to compare the signal reception quality indicator with the predetermined indicator value;
wherein if the signal reception quality indicator is superior to the predetermined indicator value, the second Bluetooth communication circuit (121) receives a mode-switching instruction generated by the main Bluetooth circuit (110), and the second control circuit (127) instructs the auxiliary Bluetooth circuit (120) to switch from the relay mode to the sniffing mode according to the mode-switching instruction.
