Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0035] figure 1 It is a schematic structural diagram of a Bluetooth mesh network provided by an embodiment of the present application. like figure 1 As shown, the Bluetooth mesh network includes nodes A-M. There is a connecting line between two nodes in the figure, indicating that the two nodes can communicate directly. figure 1 The various nodes in the Bluetooth mesh network and the communication relationship between the various nodes are only used for illustration, and are not intended to limit the Bluetooth mesh network provided by the embodiments of the present application.

[0036] Optionally, the Bluetooth mesh network provided in the embodiments of the present application may be a Bluetooth mesh network applied in building autom...

Abstract

The application discloses a data transmission method and a display device, which belong to the field of bluetooth wireless technology. After obtaining the first message sent by the first node in the Bluetooth mesh network, the processor in the display device updates the TTL in the first message to 0 when the first identification set of the display device satisfies the target condition, The second message is obtained, and then the Bluetooth component broadcasts the second message in the Bluetooth mesh network. When the destination node is a neighbor node of the display device, since the destination node will not broadcast the message after receiving the second message sent by the display device, it can ensure that the destination node receives the second message and avoid Other nodes perform invalid forwarding, reducing the waste of transmission resources. When the display device has only one neighbor node, the first node, since the first node that receives the second message broadcast by the display device will not broadcast the message again, the waste of transmission resources is reduced.

Description

technical field [0001] The present application relates to the field of Bluetooth wireless technology, and in particular, to a data transmission method and a display device. Background technique [0002] With the proposal of wireless mesh network (mesh network) technology and the continuous development of Internet of Things technology, Bluetooth (bluetooth) technology is one of the foundations of Internet of Things technology. Support mesh network. [0003] The Bluetooth mesh network can realize many-to-many transmission between devices, and can build a large-scale communication network. At present, the Bluetooth mesh network can be used in building automation, smart home and wireless sensor networks, etc., which can enable a large number of devices to transmit data in a reliable and safe environment. [0004] Devices in a Bluetooth mesh network usually use flooding for data transmission. When a certain device broadcasts a message in the Bluetooth mesh network, multiple de...
