Embodiments of the present application provide a data transmission method, apparatus and device, the method includes: sending, by a first device, first indication information to a second device if the first device does not receive a data packet sent by a data source device in a first time slot successfully, where the first device and the second device are configured to receive the data packet sent by the data source device in a same time slot; receiving the data packet sent by the data source device or the second device when the second device receives the data packet sent by the data source device in the first time slot successfully; and receiving the data packet sent by the data source device when the second device does not receive the data packet sent by the data source device in the first time slot successfully. The reliability of data transmission is improved.

Data transmission method, apparatus and device

Embodiments of the present disclosure provide a data transmission method, including: a first device receiving a data packet in a first slot, where the data packet is noise or a data packet received from a data source device; the first device determining a link state between the data source device and the first device according to the data packet, where the link state comprising an idle state or a busy state; and the first device transmitting audio data to a second device in the first slot when determining the link state being the idle state, where the audio data is audio data received by the first device from the data source device.

Data transmission method and apparatus

A Bluetooth communication method and device, and storage medium and terminal are provided. The method includes: generating a frame to be transmitted, wherein the frame to be transmitted comprises at least a Preamble, an Access Code, a Header, an Enhanced Data Rate Payload and a Trailer, wherein a configuration mode of the Preamble is consistent with a configuration mode of a Preamble in an LE frame, a configuration mode of the Header, the Enhanced Data Rate Payload and the Trailer are consistent with configuration modes of corresponding parts in an EDR frame, a configuration mode of the Access Code is consistent with a configuration mode of an Access Code in the LE frame and a configuration mode of an Access Code in the EDR frame; and generating and transmitting the frame to be transmitted by a modulation mode of the EDR frame and a Symbol Rate of the LE frame.

Bluetooth communication method and device, and storage medium and terminal

A wireless communication method, a terminal, an audio component, an apparatus and a storage medium are disclosed. The method comprises: establishing a first communication link, communicating with a first audio component of an electronic device according to the first communication link; establishing a second communication link, communicating with a second audio component of the electronic device according to the second communication link; sending a first audio data packet to the first audio component and receiving first acknowledgement information fed back by the first audio component; receiving second acknowledgement information fed back after monitoring the terminal sending the first audio data packet by the second audio component; and performing data coordination processing according to the first acknowledgement information and the second acknowledgement information. Working loads on the primary earpiece of a Bluetooth headset or on a terminal is reduced by the embodiments of the present disclosure.
