[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the embodiment of the present application is: applied to the mini-program end, sending an information synchronization instruction to the Bluetooth end, so that the Bluetooth end determines the device information based on the information synchronization instruction, and sends the device information to the mini-program end; receiving the device information sent by the Bluetooth end, sending the device information to the cloud, so that the cloud determines the OTA upgrade file of the Bluetooth end according to the device information, and sends the OTA upgrade file to the mini-program end; sending the OTA upgrade file to the Bluetooth end through the agreed Bluetooth communication protocol, so that the Bluetooth end performs OTA upgrade according to the OTA upgrade file.

[0048] In this embodiment, for the convenience of description, the following description is made by taking the identification of the OTA upgrade device as the execution subject.

[0049] With the rapid development of the Internet of Things, more and more devices are connected to the Internet. Many IoT devices have Bluetooth functions. At the same time, WeChat applets have penetrated into people's livelihood. Basically, users who use WeChat will use applets. Many Bluetooth devices are also connected and used through WeChat applets. Most devices support OTA (Over-the-Air Technology) function. OTA technology is a technology that transmits software updates, data or configuration information to devices through wireless networks. However, many devices currently provide users with a poor experience when performing OTA upgrades. For example, during the upgrade process, the signal is poor and the connection is disconnected and it has to be restarted. The upgrade package file is too large and takes a long time to transmit. The device is easily confused when it is used by multiple people. These situations occur frequently and are difficult to solve.

[0050] The present application provides a solution for transmitting OTA upgrade files through a conventional Bluetooth communication protocol, thereby improving the fault tolerance and stability of file transmission.

[0051] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an OTA upgrade device, etc. The following takes the OTA upgrade device as an example to illustrate this embodiment and the following embodiments.

[0052] Based on this, the embodiment of the present application provides an OTA upgrade method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the OTA upgrade method of the present application. The OTA upgrade method is applied to the mini program end, including steps S10 to S30:

[0053] Step S10, sending an information synchronization instruction to the Bluetooth end, so that the Bluetooth end determines the device information based on the information synchronization instruction, and sends the device information to the mini program end.

[0054] It should be noted that the Bluetooth end is a device that supports Bluetooth function, has a built-in Bluetooth module, and supports Bluetooth communication protocol. The Bluetooth end is a device equipped with a BLE module that supports Bluetooth protocol 4.0 or higher. It is characterized by reduced cost and power consumption, so it has a wide range of applications, such as: smart home (Bluetooth lock, Bluetooth light), data transmission of sensor equipment (blood pressure monitor, temperature sensor), consumer electronics (electronic cigarettes, remote control toys), etc. Bluetooth technology is an open global specification for wireless data and voice communications. It is a special short-range wireless technology connection based on low-cost short-range wireless connection to establish a communication environment for fixed and mobile devices.

[0055] In addition, it should be noted that the mini program end refers to the application or platform that runs the mini program. The mini program is an application that can be used without downloading and installing. It usually runs on third-party platforms such as WeChat, Alipay, and Baidu. The mini program end communicates with the Bluetooth end and the cloud by calling the API (application programming interface) provided by the platform. It has the characteristics of high functional scalability, small size, fast download, easy to reach, and can be used and left. It is currently widely used. It can be used by governments, enterprises, and individuals, and is basically known to everyone.

[0056] In addition, it should be noted that the information synchronization instruction refers to an instruction sent by the mini program end to the Bluetooth end, requesting the Bluetooth end to return its current status information.

[0057] In addition, it should be noted that the device information refers to the current status information of the Bluetooth terminal, including but not limited to the working status and firmware version of the Bluetooth terminal, and if the OTA upgrade file is currently being transmitted, the content and number of OTA file packages received by the Bluetooth terminal. The device information includes the working status, firmware version, and the number of OTA packages received.

[0058] Specifically, the mini program side calls the built-in Bluetooth API or related library to initialize the Bluetooth side to ensure that the Bluetooth function of the Bluetooth side is in an available state; then the mini program side starts the Bluetooth scanning function to search for available Bluetooth devices. After scanning the target Bluetooth device, it initiates a pairing request to the Bluetooth device. After the pairing is successful, the mini program side and the Bluetooth side establish a connection.

[0059] After the connection between the mini program and the Bluetooth end is established, the mini program constructs an information synchronization instruction according to the protocol and format of Bluetooth communication, and sends the information synchronization instruction to the Bluetooth end. After receiving the information synchronization instruction, the Bluetooth end sends a reply instruction to the mini program end indicating that the information synchronization instruction has been received. The information synchronization instruction is then parsed and the device information of the Bluetooth end is obtained according to the instruction requirements. The device information is then sent to the mini program end. The device information includes but is not limited to the working status of the Bluetooth end, the firmware version, and the content and quantity of the OTA file packages received.

[0060] Step S20, receiving the device information sent by the Bluetooth end, and sending the device information to the cloud, so that the cloud determines the OTA upgrade file of the Bluetooth end according to the device information, and sends the OTA upgrade file to the mini program end.

[0061] It should be noted that the cloud is a remote server or server cluster located on the network, which communicates and exchanges data with the mini-program end through the Internet. The cloud has the OTA upgrade file of the latest version of the device firmware where the Bluetooth end is located.

[0062] In addition, it should be noted that the OTA upgrade file is a file package containing the firmware update content of the device where the Bluetooth end is located. It is used to transmit the new firmware version or update content to the target device wirelessly to achieve the upgrade or update of the device. It usually contains all the update content of the device firmware, which may involve functional improvements, performance optimization, security patches, bug fixes, etc. The content of the upgrade package will vary depending on the model of the device, the current firmware version and the target firmware version. Over-the-Air (Over-the-Air) technology In the field of science and technology, OTA mainly refers to a technology that remotely updates and upgrades the software and firmware of mobile terminal devices (such as smartphones, tablets, car systems, etc.) through the air interface of mobile communications (such as Bluetooth, 2G, 3G, 4G, 5G).

[0063] Specifically, the device information sent by the Bluetooth end is received, and then the OTA upgrade file request instruction containing the device information is sent to the cloud. After receiving the device information, the cloud analyzes and obtains the firmware version of the device where the Bluetooth end is located contained in the device information, queries the cloud database to obtain the latest firmware version information, and then compares the latest firmware version with the firmware version in the device information. If the firmware version in the device information is lower than the latest firmware version, the latest version of the OTA upgrade file of the device where the Bluetooth end is located is sent to the mini program end; if the firmware version in the device information is already the latest firmware version, a reply message containing the latest version of the firmware is sent to the mini program end.

[0064] More specifically, if the firmware version in the device information is lower than the latest firmware version, a version reply message containing the latest firmware version information will be sent to the mini program end. After receiving the latest version information, the mini program end will query whether the latest version of the OTA upgrade file is cached in the local storage of the device where the mini program end is located. If there is the latest version of the OTA upgrade file, a message containing the information of the latest version of the OTA upgrade file will be sent to the cloud; if there is no latest version of the OTA upgrade file, an OTA upgrade file request instruction will be sent to the cloud. In response to the OTA upgrade file request instruction, the cloud will send the latest version of the OTA upgrade file to the mini program end. The OTA upgrade file request instruction is used to request the latest version of the OTA upgrade file from the cloud.

[0065] Step S30, sending the OTA upgrade file to the Bluetooth terminal through the agreed Bluetooth communication protocol, so that the Bluetooth terminal performs OTA upgrade according to the OTA upgrade file.

[0066] It should be noted that the agreed Bluetooth communication protocol is a customized communication protocol, which defines how to exchange data and instructions between the mini program end and the Bluetooth end. Through a series of clear rules and steps, it improves the reliability, efficiency and automation of communication between the Bluetooth device and the user end, and also facilitates the firmware management and upgrade of the device.

[0067] More specifically, the agreed-upon Bluetooth communication protocol defines clear rules and steps. The mini program sends a command to the Bluetooth end. If the Bluetooth end receives and parses the command successfully, it returns the command. If the parsing fails, the command is not returned. For example, the mini program sends an information synchronization command, and the Bluetooth end returns the information synchronization command after receiving it, indicating that the information synchronization command has been received, and then the device information of the device where the Bluetooth end is located is combined into a new data packet and sent to the mini program end; if there is no business interaction function, the Bluetooth end only returns this command. Figure 2 As shown, Figure 2This is a flowchart of the steps in the business interaction function scenario defined by the agreed Bluetooth communication protocol. The mini program sends the information synchronization instruction to the Bluetooth end. After receiving the information synchronization instruction, the Bluetooth end sends the received information synchronization instruction and device information to the mini program end. Figure 3 As shown, Figure 3 This is a step flow chart for the non-business interaction function scenario defined by the agreed Bluetooth communication protocol. The mini program side sends the OTA file upgrade package to the Bluetooth side. After receiving it, the Bluetooth side sends a message containing the received OTA file upgrade package information to the mini program side.

[0068] More specifically, the transmission data instruction format defined by the conventional Bluetooth communication protocol is referred to as Figure 4 , Figure 4 The protocol header is a fixed instruction code with an instruction prefix, which occupies 2 bytes; the command code indicates the operation type of the instruction, which occupies 1 byte, such as 01 synchronization information, 02 control function, F1 OTA upgrade and other different operations. The command code is the key to distinguish different instructions. The total number of packets indicates the total number of packets of all data, which occupies 1 byte. It is used to tell the receiver how many data packets will be in the entire data transmission process. The number of subpackets indicates the sequence number of the current transmission data packet, which occupies 1 byte. It is used to identify the position of the current data packet in the entire data transmission process, so that the receiver can reassemble the data packet in the correct order. Data 1 and data 2 indicate the data in this data packet. The number of bytes occupied changes with the maximum transmission unit MTU (Maximum Transmission Unit) value. The data field contains the specific content or parameters of the instruction. The crc check code is a field used to check the integrity of the data, which occupies 1 byte. It ensures that the data has not been tampered with or damaged during transmission by calculating the cyclic redundancy check crc value of the data field. The protocol tail is the end mark or check field of the instruction, which is used to identify the end of the instruction and / or perform additional checks, which occupies 2 bytes.

[0069] Specifically, after the mini program end receives the OTA upgrade file, it verifies the integrity and correctness of the file. After the verification is completed, the OTA upgrade file is sent to the Bluetooth end through the agreed Bluetooth communication protocol. Further, based on the total number of packets in the agreed Bluetooth communication protocol and the total file size of the OTA upgrade file, the Bluetooth maximum transmission unit MTU (Maximum Transmission Unit) in the OTA upgrade file transmission process is determined. After the maximum transmission unit is determined, the mini program end sends an MTU setting instruction to the Bluetooth end. The MTU setting instruction is used to set the space size for transmitting a file package between the mini program end and the Bluetooth end. After receiving the MTU setting instruction, the Bluetooth end modifies the maximum transmission unit of the transmission. After the modification is successful, the modification success information is returned to the mini program end. Generally, the default value of Bluetooth transmission is 20 bytes. In one embodiment of the present application, the MTU setting instruction modifies 20 bytes to 255 bytes, which increases the size of the transmitted file package and improves the transmission rate.

[0070] This embodiment adopts the above scheme to transmit OTA upgrade files through the agreed Bluetooth communication protocol, thereby improving the fault tolerance and stability of file transmission.

[0071] Based on the above implementation scheme, in a feasible implementation manner, sending the OTA upgrade file to the Bluetooth terminal through the agreed Bluetooth communication protocol includes steps S31 to S33:

[0072] Step S31, determining a maximum transmission unit for the OTA upgrade file transmission based on the conventional Bluetooth communication protocol.

[0073] It should be noted that the maximum transmission unit is the maximum transmission unit value in Bluetooth transmission. Generally, the default value of a Bluetooth device is 20 bytes per maximum transmission unit.

[0074] Specifically, based on the total number of packets in the agreed Bluetooth communication protocol and the total file size of the OTA upgrade file, the Bluetooth maximum transmission unit MTU during the OTA upgrade file transmission process is determined.

[0075] Step S32: packetize the OTA upgrade file based on the maximum transmission unit to obtain an OTA file package.

[0076] It should be noted that the OTA file package refers to small file packages obtained by subpackaging the OTA upgrade file.

[0077] Specifically, the total size of the OTA file is obtained, and according to the determined MTU value, the OTA upgrade file is split into multiple data packets whose size is less than or equal to the MTU value to obtain an OTA file packet. The format of the data packet is Figure 4The transmission data instruction format defined by the conventional Bluetooth communication protocol shown.

[0078] Step S33, sending the OTA file package to the Bluetooth terminal, and recording the synchronization information during the transmission of the OTA file package.

[0079] Specifically, the divided OTA file packages are sent to the Bluetooth end in order. When each file is sent, the mini program end records the sending time, number of packages (file package number) and other synchronization information. When the Bluetooth end receives the OTA file package, it also records the corresponding receiving time, number of packages (file package number) and other synchronization information.

[0080] This embodiment uses the above solution to determine the MTU based on the agreed Bluetooth communication protocol, which can ensure that during the Bluetooth communication process, the amount of data transmitted each time will not be too large to cause transmission failure, nor too small to waste transmission resources. This data transmission based on the MTU agreed upon in the protocol can fully utilize the bandwidth of Bluetooth communication and improve transmission efficiency.

[0081] Based on the above implementation scheme, in a feasible implementation scheme, the OTA upgrade method further includes steps S40 to S50:

[0082] Step S40, when a connection interruption occurs during the transmission of the OTA upgrade file to the Bluetooth terminal, a file transmission breakpoint where the OTA upgrade file transmission is interrupted is recorded.

[0083] It should be noted that the file transfer breakpoint refers to the end position of the last valid data packet that failed to be successfully sent due to a connection interruption during the OTA upgrade file transmission via Bluetooth. This position marks the boundary between the data that has been successfully sent and received and the data that has not yet been sent during the transmission process.

[0084] Specifically, during the OTA upgrade file transmission process, the stability of the Bluetooth connection is monitored in real time. Once the Bluetooth connection is interrupted (for example, through the receipt of an error code or abnormal signal), the file transfer is stopped immediately. The serial number of the OTA file package that has been successfully transmitted by the mini program end is recorded, and the serial number of the OTA file package that has been successfully received by the Bluetooth end is recorded. The serial number of the OTA file package that has been successfully received by the Bluetooth end is used as the file transfer breakpoint.

[0085] Step S50, reestablishing the connection with the Bluetooth end, and completely transmitting the OTA upgrade file to the Bluetooth end based on the file transfer breakpoint.

[0086] Specifically, after detecting that the connection is interrupted, try to re-initiate the Bluetooth connection request. If the Bluetooth device is in a connectable state, re-establish the Bluetooth connection. If the connection fails, retry according to a predetermined retry strategy (such as number of retries, retry interval, etc.); if multiple retries still fail, display an error message to the user, and prompt the user to check the Bluetooth device status or re-pair; after successfully re-establishing the Bluetooth connection, read the previously recorded file transfer breakpoint from the local storage or database, and locate the untransmitted part of the OTA upgrade file based on the breakpoint information, and continue to transfer the OTA upgrade file from the breakpoint. During the transmission process, continue to monitor the stability of the Bluetooth connection. When all file data packets are successfully transmitted to the Bluetooth end, send a completion signal to the Bluetooth device, indicating that the OTA upgrade file transfer is complete.

[0087] Through the above scheme, this embodiment records the file transfer breakpoints. When the connection is interrupted, it can continue from the last successful transmission location without starting from the beginning. This greatly improves the efficiency and reliability of transmission; reduces transmission failures caused by network instability or equipment failure, making the OTA upgrade process more stable while also improving the user experience.

[0088] Based on the above implementation scheme, in a feasible implementation scheme, the OTA upgrade method is applied to the Bluetooth end, including steps S60 to S70:

[0089] Step S60, receive the information synchronization instruction sent by the mini program end, determine the device information of the Bluetooth end according to the information synchronization instruction, send the device information to the mini program end, so that the mini program end sends the device information to the cloud, so that the cloud determines the OTA upgrade file of the Bluetooth end according to the device information, and sends the OTA upgrade file to the mini program end.

[0090] Specifically, after the mini program end and the Bluetooth end establish a connection, the mini program end constructs an information synchronization instruction according to the protocol and format of Bluetooth communication, and sends the information synchronization instruction to the Bluetooth end. After receiving the information synchronization instruction, the Bluetooth end parses the information synchronization instruction and obtains the device information of the Bluetooth end according to the instruction requirements, and then sends the device information to the mini program end. The device information includes but is not limited to the working status of the Bluetooth end, the firmware version, and the content and quantity of the received OTA file packages. After receiving the device information, the mini program end sends the OTA upgrade file request instruction containing the device information to the cloud. After receiving the device information, the cloud analyzes and obtains the firmware version of the device where the Bluetooth end is located contained in the device information, queries the cloud database to obtain the latest firmware version information, and sends the latest version of the OTA upgrade file of the firmware of the device where the Bluetooth end is located to the mini program end.

[0091] Step S70, receiving the OTA upgrade file sent by the mini program end through the agreed Bluetooth communication protocol, and performing OTA upgrade on the Bluetooth end according to the OTA upgrade file.

[0092] Specifically, after receiving the OTA upgrade file on the mini program side, the OTA upgrade file is packaged through the agreed Bluetooth communication protocol and then sent to the Bluetooth side in sequence. After receiving the OTA upgrade file, the Bluetooth side verifies the file and performs data verification based on the CRC check code in the OTA file package. If the data verification of the OTA upgrade file passes, the upgrade time countdown is determined according to the preset upgrade time; after the upgrade time countdown passes, the Bluetooth side is OTA upgraded based on the OTA upgrade file, and the original program of the firmware is overwritten to complete the OTA upgrade.

[0093] Based on the above implementation scheme, in a feasible implementation scheme, the OTA upgrade of the Bluetooth terminal according to the OTA upgrade file includes steps S71 to S73:

[0094] Step S71, performing data verification on the OTA upgrade file based on the conventional Bluetooth communication protocol.

[0095] Specifically, the Bluetooth end receives the OTA upgrade file sent from the mini-program end through the agreed Bluetooth communication protocol, extracts the data required for verification from the received OTA upgrade file, such as the CRC check code, uses the CRC check algorithm for verification, and compares the calculated verification result with the check value contained in the OTA upgrade file. If the verification results are consistent, it means that the OTA upgrade file is complete and has not been tampered with, and proceeds to the next step; if the verification results are inconsistent, an error message is recorded, and it may be necessary to notify the mini-program end or the user to resend the OTA upgrade file.

[0096] Step S72: If the data verification of the OTA upgrade file passes, the upgrade time countdown is determined according to the preset upgrade time.

[0097] Specifically, if the data verification of the OTA upgrade file passes, the preset OTA upgrade time is read from the device where the Bluetooth terminal is located, the current time of the Bluetooth terminal is obtained, and the upgrade countdown is obtained according to the preset upgrade time and the current time of the device, and a countdown mechanism is started. This countdown can be implemented on the internal clock or timer of the Bluetooth terminal. During the countdown, the Bluetooth terminal can continue to perform other functions, but it should be ensured that it will not enter the sleep or shutdown state before the countdown ends. In one embodiment of the present application, the preset upgrade time is twelve o'clock in the evening, the current device time is obtained, and the difference between the current time and twelve o'clock in the evening is calculated to determine the upgrade time countdown.

[0098] Step S73: After the upgrade time countdown is completed, the Bluetooth terminal is OTA upgraded based on the OTA upgrade file.

[0099] Specifically, when the countdown ends, the Bluetooth end checks its status to ensure that the upgrade time has arrived; then, according to the instructions of the OTA upgrade file, it starts to update the firmware or software of the Bluetooth end to complete the firmware overwrite upgrade. After the upgrade is completed, the Bluetooth end completes the upgrade process. After restarting, the Bluetooth end should perform a self-check to ensure that the upgrade is successful and the device functions normally, and then notify the user that the OTA upgrade has been completed.

[0100] Through the above scheme, this embodiment performs data verification on the OTA upgrade file to ensure that the file is not tampered with or damaged during the transmission process, thereby ensuring the security and integrity of the file; determining the upgrade time countdown according to the preset upgrade time can ensure that the OTA upgrade is performed at the appropriate time, avoiding upgrades during peak device usage periods or during the execution of critical tasks, and improving the stability of OTA upgrades while reducing interference to users during the upgrade process, thereby improving user experience.

[0101] Based on the above implementation scheme, in a feasible implementation scheme, the OTA upgrade method is applied to the cloud, including steps S80 to S90:

[0102] Step S80, receiving the device information sent by the mini program end, and determining the OTA upgrade file of the Bluetooth end according to the device information. The device information is determined by the Bluetooth end based on the information synchronization instruction and sent to the mini program end.

[0103] Specifically, after the communication connection is established between the mini program and the cloud, the mini program will send device information to the cloud. When the cloud receives the device information sent by the mini program, it receives and stores the information. The cloud server parses the received device information, extracts key information, obtains the current firmware version of the device where the Bluetooth end is located, queries the cloud database to obtain the latest firmware version information, and then compares the latest firmware version with the firmware version in the device information to determine the OTA upgrade file corresponding to the latest version.

[0104] Step S90, sending the OTA upgrade file to the mini program end, so that the mini program end sends the OTA upgrade file to the Bluetooth end through the agreed Bluetooth communication protocol, so that the Bluetooth end performs OTA upgrade according to the OTA upgrade file.

[0105] Specifically, if the firmware version in the device information is lower than the latest firmware version, the OTA upgrade file of the latest version of the device where the Bluetooth end is located will be sent to the mini program end; if the firmware version in the device information is already the latest firmware version, a reply message containing the latest version of the firmware will be sent to the mini program end.

[0106] More specifically, if the firmware version in the device information is lower than the latest firmware version, a version reply message containing the latest firmware version information will be sent to the mini program end. After receiving the latest version information, the mini program end will query whether the latest version of the OTA upgrade file is cached in the local storage of the device where the mini program end is located. If there is the latest version of the OTA upgrade file, a message containing the information of the latest version of the OTA upgrade file will be sent to the cloud; if there is no latest version of the OTA upgrade file, an OTA upgrade file request instruction will be sent to the cloud. In response to the OTA upgrade file request instruction, the cloud will send the latest version of the OTA upgrade file to the mini program end. The OTA upgrade file request instruction is used to request the latest version of the OTA upgrade file from the cloud.
