Method for forwarding broadcast packet in bluetooth BLE networking and system thereof

Abstract

The invention relates to a method for forwarding a broadcast packet in bluetooth low energy (BLE) MESH networking and a system thereof. The bluetooth BLE networking comprises a gateway and multiple BLE modules. One of the BLE modules is determined as the target module of the broadcast packet. The method comprises the steps that the maximum frequency T that the broadcast packet is allowed to be forwarded is set; the gateway transmits the broadcast packet to the target module; the BLE module receiving the broadcast packet judges whether the BLE module is the target module; if the judgment result is yes, a reply packet is broadcasted; and if the judgment result is no, whether the forwarding frequency of the broadcast packet is greater than T is judged so as to determine forwarding of the broadcast packet. According to the method and the system, the situation that the broadcast packet is repeatedly forwarded without limitation can be avoided so that time of processing the repeated broadcast packets can be effectively saved, waste of resources can be avoided and the network speed can be greatly enhanced.

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 ...

AI Technical Summary

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
