Problems solved by technology

As the number of devices in the Bluetooth Mesh network increases, the number of relay nodes increases greatly, resulting in a significant increase in the number of relay forwarding of broadcast packets, and the success rate of receiving broadcast packets is low, which may cause broadcast storms and network congestion.

Embodiment Construction

[0034]The Bluetooth Mesh network usually uses ADV (advertising packets) to send information, the relay forwards the broadcast packets when receiving the broadcast packets, and the target device obtains the information in the broadcast packets when receiving them. As the number of devices in the Bluetooth Mesh network increases, the number of relay nodes increases greatly. Assuming that a Bluetooth Mesh network includes 20 Bluetooth devices, each Bluetooth device can be regarded as a relay node. When using the flooding method, a broadcast packet sent by a Bluetooth device will be forwarded 20 times before reaching the target Bluetooth device. Assume that the broadcast interval of each Bluetooth device in the Bluetooth Mesh network is 100ms, and the duration of broadcasting a broadcast packet is 3ms. In the case of no conflict, 60ms of the broadcast interval is occupied by the broadcast, and only 40ms is idle. The reception success rate of broadcast packets is low.

Abstract

A bluetooth device, a bluetooth mesh network information transmission method and a readable storage medium, the bluetooth mesh network information transmission method comprising: receiving a broadcast packet, and obtaining the type of the broadcast packet, the broadcast packet is sent by the bluetooth mesh network When the type of the broadcast packet is non-connectable and non-directional, use the radio frequency switching duration as the channel transmission interval, switch the broadcast channel, and send the broadcast packet on the switched broadcast channel; the The radio frequency switching duration is less than the preset inter-frame interval. The foregoing solution can improve the success rate of receiving broadcast packets and reduce the probability of broadcast storms.

Description

technical field [0001] The embodiment of the present invention relates to the field of bluetooth communication, in particular to a bluetooth device, a bluetooth Mesh network information transmission method and a readable storage medium. Background technique [0002] The transmission distance of wireless network communication is usually limited, and the transmission distance of wireless network communication can be extended by adopting wireless mesh (Mesh) network technology. In a Bluetooth Mesh network, all devices can communicate with other devices directly or indirectly. [0003] In a Bluetooth Mesh network, a routing method or a flooding method may be used to implement communication between two devices. When using the path selection method, two devices communicate through a specific path in the Mesh network; when using the flooding method, one device sends information to other devices in the Mesh network, and other devices in the Mesh network serve as relays The informa...
