1. An auxiliary Bluetooth circuit (120) of a multi-member Bluetooth device (100), wherein the multi-member Bluetooth device (100) is utilized for communicating data with a remote Bluetooth device (102) and comprises the auxiliary Bluetooth circuit (120) and a main Bluetooth circuit (110), the auxiliary Bluetooth circuit (120) comprising:

  • a Bluetooth communication circuit (121);

    a data transmission circuit (123); and

    a control circuit (125) arranged to operably control the data transmission circuit (123) to communicate data with the main Bluetooth circuit (110), and arranged to operably utilize the Bluetooth communication circuit (121) to sniff packets issued from the remote Bluetooth device (102) when the main Bluetooth circuit (110) conducts a bidirectional packet transmission with the remote Bluetooth device (102);

    wherein the data transmission circuit (123) is further arranged to operably receive missing packets of the auxiliary Bluetooth circuit (120) from the main Bluetooth circuit (110) when the auxiliary Bluetooth circuit (120) has missed packets issued from the remote Bluetooth device (102);

    wherein the control circuit (125) is further arranged to operably detect whether the main Bluetooth circuit (110) is disabled or disappears by evaluating a situation of data communication between the main Bluetooth circuit (110) and the auxiliary Bluetooth circuit (120); and

    the control circuit (125) is further arranged to operably conduct a bidirectional packet transmission with the remote Bluetooth device (102) through the Bluetooth communication circuit (121) when the main Bluetooth circuit (110) is disabled or disappears, so as to avoid the control circuit (125) from missing packets issued from the remote Bluetooth device (102).
