Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Bluetooth is a point-to-point or point-to-multipoint topology, but the interaction between them is based on a physical channel. Among them, point-to-multipoint can share a physical channel. In a piconet based on the same physical channel, the hardware device can act as a master or a slave, and the specific device role can be selected by the device to realize the corresponding control function ( Only one master device can exist in a piconet). Of course, there may be crossover between different piconets, that is, a slave device in one piconet can serve as a master device in another piconet. ...

Abstract

The embodiment of the invention provides a Bluetooth communication method and a Bluetooth communication device, a Bluetooth system and Bluetooth equipment. The method comprises the steps of during a Bluetooth communication process, distributing bandwidth resources into a first bandwidth resource used for communicating with data source equipment and a second bandwidth resource used for communicating with slave equipment; during a process of communicating with the data source equipment, receiving and caching data from the data source equipment; during a process of communicating with the slave equipment, judging a cached data size is less than a first threshold; and when the cached data size is less than the first threshold, using at least one part of the second bandwidth resource to communicate with the data source equipment.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a bluetooth communication method, a device thereof, a bluetooth system and a bluetooth device. Background technique [0002] Various types of wireless transmission devices, such as smart phones, Bluetooth headsets, MP3 players, etc., are now widely used. Most wireless transmission devices can support Bluetooth to transmit audio or other various types of data. In the Bluetooth protocol (A2DP prfile), a data output device (such as a smart phone, MP3 player, etc.) can only be connected to one audio playback device, and the data is transmitted to the audio playback device via Bluetooth for playback. [0003] In some application scenarios, it is necessary for the data output source to transmit data to two or more audio playback devices. For example, a stereo headset needs to establish a wireless connection between the left and right channel playback devices and the data output sour...
