Abstract: The present invention provides an electronic device including a wireless communication module, a counter and a processing circuit. The wireless communication module is configured to receive a first packet and a second packet from another electronic device, wherein the first packet includes a first counter value, the second packet includes a second counter value, and the first counter value and the second counter value correspond to two adjacent edges of an original signal of another electronic device, respectively. The processing circuit is configured to obtain a third counter value from the counter when the first packet is received, and obtain a fourth counter value from the counter when the second packet is received; and the processing circuit further generates an output signal that is substantially the same as the original signal according to the first counter value, the second counter value, the third counter value and the fourth counter value.

Abstract: An auxiliary Bluetooth circuit of a multi-member Bluetooth device for communicating data with a source Bluetooth device acting as a master in a first piconet. A main Bluetooth circuit of the multi-member Bluetooth device acts as a slave in the first piconet, acts as a master in a second piconet, and 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 acts as a slave in the second piconet and 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.
