Bluetooth 5.2 connects to the Xiaodu Smart Speaker to transmit digital audio signals. The following is a detailed explanation: 1. Bluetooth transmission is essentially a digital signal. Bluetooth technology converts audio signals into data packets through digital encoding (such as SBC, AAC, LC3, and other codecs), with no analog signals involved throughout the process. The … Read more
