Abstract: A multi-member Bluetooth device for communicating data with a source Bluetooth device acting as a master in a first piconet. The multi-member Bluetooth device includes a main Bluetooth circuit acting as a slave in the first piconet and as a master in a second piconet, and an auxiliary Bluetooth circuit acting as a slave in the second piconet. The main Bluetooth circuit generates a first slave clock and a second main clock according to a first main clock generated by the source Bluetooth device, with which both the first slave clock and the second main clock are synchronized. The auxiliary Bluetooth circuit generates a second slave clock and a third slave clock according to the second main clock, with which both the second slave clock and the third slave clock are synchronized. The auxiliary Bluetooth circuit sniffs Bluetooth packets transmitted through the first piconet from the source Bluetooth device.

Abstract: A Bluetooth audio broadcasting system includes: an audio broadcasting device, a first Bluetooth member device, and a second Bluetooth member device. The audio broadcasting device broadcasts BLE audio packets. After the first Bluetooth member device issues a volume adjusting request, the audio broadcasting device transmits a volume adjusting instruction to the first Bluetooth member device and the second Bluetooth member device. The first Bluetooth member device acquires a predetermined audio data from the BLE audio packets, controls a first audio playback circuit to playback the predetermined audio data, and adjusts an audio volume of the first audio playback circuit according to the volume adjusting instruction. The second Bluetooth member device acquires the predetermined audio data from the BLE audio packets, controls a second audio playback circuit to playback the predetermined audio data, and adjusts an audio volume of the second audio playback circuit according to the volume adjusting instruction.

Abstract: A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the auxiliary Bluetooth circuit sniffs packets transmitted from the remote Bluetooth device while the main Bluetooth circuit receives packets issued from the remote Bluetooth device, and the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the throughput of packets sniffed by the auxiliary Bluetooth circuit is lower than a predetermined threshold. In the period during which the auxiliary Bluetooth circuit operates at the relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit, and the auxiliary Bluetooth circuit does not sniff packets issued from the remote Bluetooth device.

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.

Abstract: A wireless device includes a radio-frequency module, a modem module, and a control unit. The radio-frequency module and the modem module operate either in a first operation mode or in a second operation mode. The control unit, coupled to the RF and the modem module, generates a control signal to indicate to the RF and the modem module to operate in the first operation mode or to operate in the second operation mode. A first set of signal formats corresponding to the first operation mode is a superset of a second set of signal formats corresponding to the second operation mode, and a first power consumption corresponding to the first operation mode is higher than a second power consumption corresponding to the second operation mode.

Abstract: A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit; the auxiliary Bluetooth circuit does not sniff packets issued from the remote Bluetooth device, but will switch to a sniffing mode if a signal reception quality indicator of the auxiliary Bluetooth circuit is superior to a predetermined indicator value. In the period during which the auxiliary Bluetooth circuit operates at the sniffing mode, the auxiliary Bluetooth circuit sniffs packets issued from the remote Bluetooth device and the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device.
