The components of the system can be interconnected by any form or medium of digital data communication, eg, a communication network. Examples of communication networks include: local area networks (LANs), wide area networks (WANs), blockchain networks, and the Internet.

A computing system can include clients and servers. Clients and servers are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also known as a cloud computing server or a cloud host. It is a host product in the cloud computing service system to solve the problems of difficult management and weak business expansion in traditional physical hosts and VPS services. defect.

It should be understood that steps may be reordered, added or deleted using the various forms of flow shown above. For example, each step described in the present invention may be executed in parallel, sequentially, or in a different order, as long as the desired result of the technical solution of the present invention can be achieved, there is no limitation herein.

The above specific implementation methods do not constitute a limitation to the protection scope of the present invention. It should be apparent to those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made depending on design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

Claims (8)

1. A software updating method applied to a bluetooth device comprising a bluetooth master-slave function, comprising:

transmitting handshake information according to a set frame format through Bluetooth broadcasting;

receiving response information of a plurality of slave devices, wherein the response information of each slave device comprises a Media Access Control (MAC) address of the slave device;

respectively transmitting burning data to each slave device according to a set frame format, wherein the burning data is used for updating the software program of each slave device;

after the data is transmitted to each slave device according to the set frame format, the method further comprises the following steps:

receiving a data request reported by at least one slave device, wherein the data request comprises an MAC address of the slave device;

and sending missing data to the corresponding slave equipment according to the MAC address.

2. The method of claim 1, wherein the set frame format comprises the following fields:

synchronizing the frames; a package type; packet enablement; a data acquisition type; an equipment address to be updated; a packet address; a packet length; data; and (5) cyclic redundancy check.

3. The method of claim 1, further comprising, prior to transmitting the handshake information in the set frame format via bluetooth broadcast:

and receiving the update parameters and the update data set by the user through the serial port, wherein the update parameters comprise the number of the equipment to be updated and the length of the broadcast data, and the update data comprise hexadecimal data of the software program to be updated.

4. The method of claim 3, further comprising, prior to downloading the burned data to each of the slave devices in the set frame format, respectively:

and if the number of the slave devices sending the response information reaches the number of the devices to be updated, sending handshake completion information through Bluetooth broadcasting.

5. A software updating method applied to a bluetooth device comprising a bluetooth master-slave function, comprising:

receiving a broadcast containing handshake information sent by a main device through a Bluetooth scanning function;

returning response information according to the handshake information, wherein the response information comprises a Media Access Control (MAC) address of the slave device;

receiving burning data in a set frame format issued by main equipment, and updating a software program according to the burning data;

before the software program is updated according to the burning data, the method further comprises the following steps:

determining missing data by comparing the packet address of the burnt data with a hash check value;

and reporting a data request to request the master device to send the missing data, wherein the data request comprises the MAC address of the slave device.

6. The method of claim 5, wherein the set frame format comprises the following fields:

synchronizing the frames; a package type; packet enablement; a data acquisition type; an equipment address to be updated; a packet address; a packet length; data; and (5) cyclic redundancy check.

7. A bluetooth device, comprising:

one or more processors;

a storage means for storing one or more programs;

when executed by the one or more processors, causes the one or more processors to implement the software update method of any of claims 1-6.

8. A computer readable storage medium, on which a computer program is stored, characterized in that the program, when being executed by a processor, implements the software updating method according to any of claims 1-6.
