Problems solved by technology

[0003] However, this communication method has disadvantages at the same time: since the communication between modules does not need to be connected, when one of the BLE modules sends data to another BLE module, the broadcast packet it sends can be sent by each BLE module in the MESH network. Received and forwarded, if the number of BLE modules is large, a large number of forwarded data packets will easily cause network congestion of the MESH network, which will greatly reduce the communication speed

Embodiment Construction

[0041] The basic idea of ​​the present invention is: by specifying the maximum number of broadcast packets allowed to be forwarded and the number of times allowed to request retransmission, it is possible to avoid repeated broadcast packets being forwarded in large numbers, thereby causing MESH network congestion.

[0042] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0043] figure 2 It is a flow chart of Embodiment 1 of the method for forwarding broadcast packets in the Bluetooth BLE MESH networking of the present invention.

[0044] Wherein, the Bluetooth BLE networking includes: a gateway and multiple BLE modules, and one of the BLE modules is determined as the target module.

[0045] Step 200, setting the maximum number of times T that the broadcast packet is allowed to be forwarded;

[0046] In the present invention, when there are many Bluetooth BLE modules in the MESH network, the minimum number of...

Abstract

The present invention involves a method and system for reposting the broadcast package for a Bluetooth low energy consumption (BLE) MESH.This method includes: to set up the maximum number of reposting the broadcast package; the gateway sends a broadcast package to the destination module; the BLE module that receives the broadcast package determines whether it is the purpose of the purpose;Whether the number of times the broadcast package is reposted is greater than T to determine whether to forward the broadcast package.The methods and systems of the present invention can avoid repeated reposting of broadcast packages without restrictions, effectively saving the time to handle repeated broadcast packages, thereby avoiding waste of resources and greatly enhance the speed of the network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for forwarding broadcast packets in a Bluetooth BLE networking. Background technique [0002] Bluetooth Low Energy (Bluetooth BLE (abbreviation for Bluetooth Low Energy)) after MESH networking, the communication between the BLE module and the BLE module does not need to be connected, but is carried out by broadcasting. The advantage of this communication method is There is no need for handshake connection during communication, which saves time, and when the number of BLE modules is very large, the communication time will be greatly shortened because there is no need to connect, such as figure 1 shown. [0003] However, this communication method has disadvantages at the same time: since the communication between modules does not need to be connected, when one of the BLE modules sends data to another BLE module, the broadcast packet it sends can be sent ...
