摘要： An audio data transmission method includes encapsulating, based on a physical layer frame header, a protocol data unit (PDU) including audio data, to obtain an audio data packet, where the physical layer frame header is modulated using a first digital modulation scheme, the PDU is modulated using a second digital modulation scheme, a value of a modulation rate of the first digital modulation scheme is equal to a value of a data transmission rate, and a value of a modulation rate of the second digital modulation scheme is less than the value of the data transmission rate, and sending the audio data packet on a BLUETOOTH low energy (BLE) physical channel at the data transmission rate.

摘要： A first device performs periodic scanning alternately, where a first scanning periodicity is used for a first-type Bluetooth connection, and a second scanning periodicity is used for a second-type Bluetooth connection; the first device receives a first-type data packet from a second device in a first scan window of any first scanning periodicity, where the first-type data packet is used to establish the first-type Bluetooth connection; the first device obtains, based on the first-type data packet, a second connection parameter for establishing the second-type Bluetooth connection to the second device; and the first device establishes the second-type Bluetooth connection to the second device based on the second connection parameter.

摘要： A frequency hopping communication method for short-distance wireless communication between a primary device and a secondary device comprises switching by the primary device from the second frequency hopping sequence to the first frequency hopping sequence at a time point of frequency hopping switching, wherein M reserved channels are between a first frequency hopping sequence and a second frequency hopping sequence; and performing frequency hopping communication with the secondary device based on the first frequency hopping sequence.
