Classification: CPC H | IPC H

Claim 5:
6. A main Bluetooth circuit (110) of a multi-member Bluetooth device (100) utilized to operably conduct data transmission with a remote Bluetooth device (102) and comprising the main Bluetooth circuit (110) and an auxiliary Bluetooth circuit (120) which selectably operates at a sniffing mode or a relay mode, the main Bluetooth circuit (110) comprising:
a first Bluetooth communication circuit (111);
a first packet parsing circuit (113), arranged to operably parse packets received by the first Bluetooth communication circuit (111); and
a first control circuit (117), coupled with the first Bluetooth communication circuit (111) and the first packet parsing circuit (113);
wherein in a period during which the auxiliary Bluetooth circuit (120) operates at the relay mode, the first control circuit (117) utilizes the first Bluetooth communication circuit (111) to receive packets transmitted from the remote Bluetooth device (102), and utilizes the first Bluetooth communication circuit (111) to forward received packets to the auxiliary Bluetooth circuit (120), and the auxiliary Bluetooth circuit (120) receives packets forwarded from the first Bluetooth communication circuit (111), but the auxiliary Bluetooth circuit (120) does not sniff packets issued from the remote Bluetooth device (102);
in a situation of that a signal reception quality indicator of the auxiliary Bluetooth circuit (120) is superior to a predetermined indicator value, the auxiliary Bluetooth circuit (120) switches from the relay mode to the sniffing mode; and
in a period during which the auxiliary Bluetooth circuit (120) operates at the sniffing mode, the first control circuit (117) utilizes the first Bluetooth communication circuit (111) to receive the packets transmitted from the remote Bluetooth device (102), and the auxiliary Bluetooth circuit (120) sniffs the packets issued from the remote Bluetooth device (102).
