example 1

[0055] Example 1, select an alternative path for OTA upgrade of the second Bluetooth mesh device 203:

[0056] The number of links in the alternative path 1 is 2, and the number of links in the alternative path 2 is 3; according to the principle of the shortest path, the alternative path 1 is selected, such as Figure 5 shown.

example 2

[0057] Example 2, select an alternative path for OTA upgrade of the fifth Bluetooth mesh device 206:

[0058] Alternative path one, mesh gateway 200→first Bluetooth mesh device 202(-20dbm)→fifth Bluetooth mesh device 206(-15dbm);

[0059] Alternative path two, mesh gateway 200 → fourth Bluetooth mesh device 205 (-35dbm) → fifth Bluetooth mesh device 206 (-13dbm);

[0060] The number of links between the alternative path 1 and the alternative path 2 is 2, the signal quality sum of the alternative path 1 is -35dbm, and the signal quality sum of the alternative path 2 is -48dbm; because -35dbm>-48dbm, according to the The principle of maximum signal strength under the condition of the same path length, so choose the alternative path 1, such as Image 6 shown.

Abstract

The invention provides a firmware upgrading method, a Bluetooth mesh networking system and a Bluetooth system. The method comprises the steps that an associated device list is constructed, a device association relationship is stored in the associated device list, and the device association relationship is used for representing device information of a Bluetooth mesh device; determining a target Bluetooth mesh device to be subjected to firmware upgrading; a firmware upgrading path is determined at least according to the associated device list, the starting point of the firmware upgrading path is the mesh gateway, and the terminal point of the firmware upgrading path is the target Bluetooth mesh device; and sending the firmware upgrade package to the target Bluetooth mesh device according to the firmware upgrade path to realize firmware upgrade. According to the method, only the firmware upgrade package is sent to the target Bluetooth mesh device, and the target Bluetooth mesh device does not need to occupy a channel for a long time for upgrading, so that the problem of relatively low OTA firmware upgrade efficiency of the Bluetooth mesh device in the prior art is solved.

Description

technical field [0001] The present application relates to the network field, and in particular, relates to a firmware upgrade method, a Bluetooth mesh networking system, a Bluetooth system, a computer-readable storage medium and a processor. Background technique [0002] The existing OTA firmware upgrade method of the Bluetooth mesh device is mainly that the Bluetooth mesh gateway communicates with the Bluetooth mesh device through the Mesh Beacon to implement the upgrade. This method occupies the original channel, and the OTA firmware upgrade is inefficient and time-consuming, and will affect the original stability of the Mesh system. Contents of the invention [0003] The main purpose of this application is to provide a firmware upgrade method, a Bluetooth mesh networking system, a Bluetooth system, a computer-readable storage medium and a processor, so as to solve the problem of low OTA firmware upgrade efficiency of Bluetooth mesh devices in the prior art.
