Abstract

A main Bluetooth circuit of a multi-member Bluetooth device includes: a Bluetooth communication circuit; a data transmission circuit; and a control circuit arranged to operably conduct bidirectional packet transmission with a remote Bluetooth device through the Bluetooth communication circuit by utilizing a Bluetooth wireless transmission approach, and arranged to operably communicate data with other devices through the data transmission circuit. During the period in which the Bluetooth communication circuit conducts packet transmission with the remote Bluetooth device, an auxiliary Bluetooth circuit of the multi-member Bluetooth device sniffs packets transmitted from the remote Bluetooth device. When the control circuit has detected that the auxiliary Bluetooth circuit missed packets transmitted from the remote Bluetooth device, the control circuit is further arranged to operably transmit missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.

Dependent claims

A main Bluetooth circuit (110) 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 main Bluetooth circuit (110) and an auxiliary Bluetooth circuit (120), the main Bluetooth circuit (110) comprising:

a Bluetooth communication circuit (111);
a data transmission circuit (113);
and
a control circuit (115) arranged to operably conduct a bidirectional packet transmission with the remote Bluetooth device (102) through the Bluetooth communication circuit (111) by utilizing a Bluetooth wireless transmission approach, and arranged to operably communicate data with other devices through the data transmission circuit (113);
wherein when the Bluetooth communication circuit (111) conducts the bidirectional packet transmission with the remote Bluetooth device (102), the auxiliary Bluetooth circuit (120) sniffs packets issued from the remote Bluetooth device (102);
and
when the control circuit (115) has detected that the auxiliary Bluetooth circuit (120) has missed packets issued from the remote Bluetooth device (102), the control circuit (115) is further arranged to operably transmit missing packets of the auxiliary Bluetooth circuit (120) to the auxiliary Bluetooth circuit (120) through the data transmission circuit (113).
