Abstract

The embodiment of the invention provides a data transmission method, a node control method, network equipment and a network system, and is particularly suitable for various chips which are based on an RISC-V architecture instruction set and comprise a Bluetooth communication chip and are widely applied. The data transmission method is applied to a node of a Bluetooth network, and comprises the following steps: obtaining at least two aggregated data packets to be sent through a Bluetooth bearing layer; the at least two to-be-sent data packets are aggregated and packaged through the Bluetooth bearing layer to obtain a Bluetooth broadcast packet, the Bluetooth broadcast packet carries the at least two to-be-sent data packets and packet header information corresponding to the at least two to-be-sent data packets, and the packet header information is used for at least indicating the length of the to-be-sent data packets; and sending the Bluetooth broadcast packet to a node of the Bluetooth network. According to the scheme, a plurality of data packets can be carried in the Bluetooth broadcast packet sent by one-time Bluetooth broadcast, so that the packet sending efficiency is greatly improved, and the scheme is applicable to a low-delay scene.

Description

technical field [0001] The embodiments of the present application relate to the field of Bluetooth technology, and in particular, to a data transmission method, a node control method, a network device, and a network system. Background technique [0002] Compared with Zigbee network, Bluetooth network (Bluetooth Mesh) can realize multi-point communication at the same time, and can communicate through any device supporting Bluetooth Low Energy (BLE) such as smart phone without special gateway, which makes Bluetooth Mesh in smart home. It has a wide range of applications in the Internet of Things environment. [0003] However, the Bluetooth mesh network generally adopts the principle of flooding, which is easy to cause network storms. In order to reduce the risk of network storms, the Bluetooth mesh network has the shortest packet sending interval or the highest packet sending frequency, which is used to limit the nodes in the Bluetooth mesh network from sending packets freque...
