Multi-member bluetooth device capable of avoiding signal interrupt

A multi-member Bluetooth device (100) for communicating data with a remote Bluetooth device (102), the multi-member Bluetooth device (100) comprising:

• a main Bluetooth circuit (110), comprising:
• a first Bluetooth communication circuit (111);
• a first data transmission circuit (113);
• and
• a first control circuit (115) arranged to operably conduct a bidirectional packet transmission with the remote Bluetooth device (102) through the first Bluetooth communication circuit (111) by utilizing a Bluetooth wireless transmission approach, and arranged to operably communicate data with other devices through the first data transmission circuit (113);
• and
• an auxiliary Bluetooth circuit (120), comprising:
• a second Bluetooth communication circuit (121);
• a second data transmission circuit (123);
• and
• a second control circuit (125) arranged to operably control the second data transmission circuit (123) to communicate data with the first data transmission circuit (113);
• wherein when the first Bluetooth communication circuit (111) conducts the bidirectional packet transmission with the remote Bluetooth device (102), the second control circuit (125) utilizes the second Bluetooth communication circuit (121) to sniff packets issued from the remote Bluetooth device (102);
• and
• when the first control circuit (115) has detected that the auxiliary Bluetooth circuit (120) has missed packets issued from the remote Bluetooth device (102), the first control circuit (115) is further arranged to operably transmit missing packets of the auxiliary Bluetooth circuit (120) to the second data transmission circuit (123) through the first data transmission circuit (113).
