Bluetooth-based data transmission method and device

Abstract

The embodiment of the invention discloses a Bluetooth-based data transmission method and device, and relates to the technical field of data processing. According to the Bluetooth-based data transmission method and device, the transmission continuity of audio data can be guaranteed, therefore, the condition that an audio play equipment end generates the play blocking and unsmoothness phenomena is avoided, and the listening experience of a user is improved. According to the main technical scheme, the method comprises the steps that to-be-transmitted audio data is acquired; the audio data is compressed according to a preset coding and decoding algorithm to obtain a to-be-transmitted data packet, wherein the preset coding and decoding algorithm is the algorithm which is used for compressing and determined according to a preset mapping relation between the sizes of to-be-transmitted files and the Bluetooth communication bandwidths; and by means of a Bluetooth technology, the to-be-transmitted data packet is sent to a receiving terminal, so that the receiving terminal decompresses the received audio data according to the preset coding and decoding algorithm and then plays the audio data.The Bluetooth-based data transmission method and device are mainly used for transmitting data between different terminals by means of the Bluetooth technology.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, in particular to a Bluetooth-based data transmission method and device. Background technique [0002] Bluetooth (Bluetooth) is an open global specification technical standard for wireless data and voice communication. It is based on short-range wireless connections and establishes a special connection for different terminals in the same communication environment. Wireless information exchange between computers, wireless earphones, speakers, related peripherals and many other devices. [0003] At present, when playing an audio file, you can use Bluetooth to send the audio file to be played to the audio playback device. For example, use the mobile phone software to select the song to be played and send it to the speaker for playback. In turn, you can use the high-quality playback of the audio playback device. The function optimizes the playback of audio files and ...

Problems solved by technology

However, when the amount of data corresponding to the target audio file received by the audio playback device is large (for example: high-fidelity sound quality files, etc.), it is easy to exceed the current rated data throughput in the process of transmitting data to the audio playback device via Bluetooth , resulting in data blockage, which in turn prevents the audio files from being continuously transmitted to the audio playback device. The audio playback device appears to be stuck and not smooth, which greatly reduces the user's listening experience.
