The embodiments of the present application do not limit the specific types of computer devices.

[0069] The device upgrading method provided in the embodiments of the present application can be applied to computer devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, Augmented Reality (AR) / Virtual Reality (VR) devices, notebook computers, Ultra-Mobile Personal Computers (UMPCs), netbooks, Personal Digital Assistants (PDAs), and the like, and can be connected in communication with various target devices, for example, in Bluetooth connection or local area network connection to implement firmware upgrading for various target devices. The embodiments of the present application do not limit the specific types of computer devices.

[0070] As shown in FIG. 1, Figure 1 The device upgrading method provided in the embodiments of the present application can be applied to computer devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, Augmented Reality (AR) / Virtual Reality (VR) devices, notebook computers, Ultra-Mobile Personal Computers (UMPCs), netbooks, Personal Digital Assistants (PDAs), and the like, and can be connected in communication with various target devices, for example, in Bluetooth connection or local area network connection to implement firmware upgrading for various target devices. The embodiments of the present application do not limit the specific types of computer devices.

[0071] In step S1, a unique device fingerprint is generated for each target device in the to-be-identified devices.

[0072] In the application, there are generally a plurality of to-be-identified devices, a target device in the to-be-identified devices is a trusted device, only the target device is a device to be subjected to firmware upgrading, and each target device corresponds to a unique device fingerprint.

[0073] In step S2, the communication protocol of the target device is queried in a configuration file based on the device fingerprint.

[0074] In the application, the configuration file includes configuration information of the target device, for example, device model, device communication protocol information, upgrade instruction, service UUID (Universally Unique Identifier), firmware version, hardware version, device name, device model and the like, and the configuration information of the corresponding target device can be uniquely found through one device fingerprint.

[0075] In the application, the communication protocols of different devices can be different, and accurate communication protocol information is required to ensure the communication quality. For example, the industrial control protocols of terminal devices for communicating with devices through Bluetooth include Modbus RTU and CANBus protocols; the data frame formats of the two are different, Modbus RTU is a fixed format (address + function code + length + data + verification), and CAN Bus is a flexible format (ID + data + length + verification).

[0076] In step S3, a total upgrade firmware package of the target device is acquired, firmware verification is performed on the total upgrade firmware package, and a firmware verification result is generated.

[0077] In the application, the total upgrade firmware package is the latest firmware package acquired from an upgrade server, and in a case where the total upgrade firmware package cannot be acquired from the server, a local firmware package can also be acquired from the local device as the total upgrade firmware package.

[0078] In step S4, in a case where the firmware verification result indicates that the total upgrade firmware package passes the firmware verification, a firmware data unit queue and a total package verification value are generated based on the total upgrade firmware package, the firmware data unit queue includes a plurality of firmware data units, and each firmware data unit includes one firmware block and a block verification code corresponding to the firmware block.

[0079] In the application, the total upgrade firmware package is divided according to a fixed number of bytes (for example, 4 KB per block), or the firmware blocks are adaptively divided according to the buffer capacity of the device; each block has a block number, the block number can be sequentially numbered according to the order of the firmware block in the total upgrade firmware package, and is used for indexing and sequence control. By dividing the firmware blocks, the amount of data transmitted at a time can be reduced, transmission failures caused by unstable network can be reduced, breakpoint resume and retransmission strategies can be supported, and block processing and verification on a low-resource device can be facilitated.

[0080] In an application, based on a preset check algorithm, such as a cyclic redundancy check, a corresponding block check code is generated for each firmware block, and the firmware block and the corresponding block check code are added to the firmware data unit queue as a firmware data unit. In an application, a total package check value can be generated for the entire total upgrade firmware package based on an integrity check algorithm.

[0081] Step S5, based on the device fingerprint, obtaining an upgrade instruction set of the target device, the upgrade instruction set comprising a plurality of upgrade instructions.

[0082] In an application, the upgrade instructions in the upgrade instruction set of the target device are used to indicate specific firmware upgrade steps of the target device, and the upgrade instruction sets of different models of devices are different.

[0083] In an application, after obtaining the upgrade instruction set of the target device from the configuration file according to the device fingerprint of the target device for the first time, the device fingerprint of the target device and the upgrade instruction set thereof can be stored as a fingerprint upgrade data in a fingerprint upgrade library, and the upgrade instruction set of the target device can be obtained from the fingerprint upgrade library according to the device fingerprint in the future. In the case that the upgrade instruction set fails to be obtained from the fingerprint upgrade library, the upgrade instruction set is obtained from the configuration file according to the device fingerprint. The fingerprint upgrade library can improve the speed of obtaining the upgrade instruction set.

[0084] Step S6, based on the communication protocol, the upgrade instruction set, the firmware data unit queue and the total package check value, upgrading the target device.

[0085] The device upgrade method provided by the embodiments of the present application can be applied to the automatic firmware upgrade of devices of different types and different communication protocols, and can meet the upgrade requirements of devices of different types and different communication protocols. The device upgrade method provided by the present application can be based on multi-threading to simultaneously upgrade multiple devices, and is not limited by differences in device models, communication protocols, etc.

[0086] In one embodiment, before the step S1, for each target device in the to-be-identified devices, a unique device fingerprint is generated, and the step S1 further comprises:

[0087] Step S01, scanning the devices and establishing a preliminary connection with each to-be-identified device scanned.

[0088] Step S02, obtaining service information of each to-be-identified device establishing the preliminary connection respectively.

[0089] Step S03, respectively matching each to-be-identified device in the configuration file according to the service information of each to-be-identified device, and determining whether each to-be-identified device is a target device.

[0090] In application, the service information of the device to be identified includes a service UUID (Universally Unique Identifier) of the device. The service information is searched in a configuration file according to the service UUID of the device to be identified. If a device with the same service UUID is found, the device to be identified is determined as the target device.

[0091] In one embodiment, the step S1, a unique device fingerprint is generated for each target device in the device to be identified, including:

[0092] Step S11, the unique identifier and service information of each target device are obtained.

[0093] Step S12, a device fingerprint is generated for each target device according to the unique identifier and service information of each target device.

[0094] In application, the unique identifier of the target device is a hardware unique identifier of the target device, such as a mac address (Media Access Control Address).

[0095] In one embodiment, the total upgrade firmware package includes the latest firmware package, and the step S3, the total upgrade firmware package of the target device is obtained, and the firmware package is checked, and a firmware check result is generated, including:

[0096] Step S31, based on the communication protocol, the target device is communicated to obtain the device model and the current firmware version of the target device.

[0097] Step S32, the latest firmware version of the target device is queried based on the device model.

[0098] Step S33, in the case that the latest firmware version is different from the current firmware version, the latest firmware package of the target device is obtained.

[0099] In application, in most cases, the latest firmware version may be higher than the current firmware version, and the firmware version of the target device is upgraded. In some cases, for example, in the case that the current firmware version has a problem, the latest firmware version can be one version lower than the current firmware version, so that the firmware version is downgraded to the previous version which is more secure and stable.

[0100] Step S34, the latest firmware package is parsed to obtain the first device model corresponding to the latest firmware package.

[0101] In this application, if the latest firmware package is an unencrypted file, it can be parsed directly. If the latest firmware package is an encrypted file, it must first be decrypted using the password before parsing. The applicable device model for this firmware package is determined by parsing the first device model number in the latest firmware package.

[0102] Step S35: If the first device model and the target device model are the same, generate a firmware verification result to indicate that the total upgrade firmware package has passed firmware verification.

[0103] In application, if the first device model and the target device model are the same, it indicates that the general upgrade firmware package is suitable for the target device and can be used for firmware upgrades on the target device. Therefore, a firmware verification result is generated to indicate that the general upgrade firmware package has passed firmware verification. If the first device model and the target device model are different, it indicates that the general upgrade firmware package is not suitable for the target device.

[0104] like Figure 2 As shown, in one embodiment, step S4, when the firmware verification result indicates that the total upgrade firmware package has passed firmware verification, generates a firmware data unit queue and a total package verification value based on the total upgrade firmware package, including:

[0105] Step S41: If the firmware verification result indicates that the total upgrade firmware package has passed the firmware verification, the total upgrade firmware package is divided into multiple firmware blocks.

[0106] In this application, taking a firmware file size of 150kb and Bluetooth data transmission as an example, the maximum value of the Bluetooth Maximum Transmission Unit (MTU) is 517 bytes; 150 KB = 150 × 1,024 = 153,600 bytes; with the MTU set to 500 bytes, a 150kb firmware file needs to send data 308 times consecutively. That is, the total 150kb firmware upgrade package array is divided into 308 parts, each containing 500 bytes of data.

[0107] Step S42: Based on the device fingerprint, query the firmware package verification algorithm set corresponding to the target device in the configuration file.

[0108] In applications, different devices require different verification algorithms. The set of verification algorithms includes the verification algorithms required by the target device at each stage. For example, cyclic redundancy check is required in the firmware block verification stage, and integrity verification algorithms, such as checksum algorithms, are required in the verification stage of the total upgrade firmware package.

[0109] Step S43: Generate the total package verification value of the total upgrade firmware package and the block verification code corresponding to each firmware block according to the verification algorithms in the firmware package verification algorithm set.

[0110] Step axis S44, respectively, assembles each firmware block and its corresponding block check code into a firmware data unit, and adds the firmware data unit to the firmware data unit queue.

[0111] In one embodiment, step S6, upgrading the target device based on the communication protocol, the upgrade instruction set, the firmware data unit queue, and the total package checksum, includes:

[0112] Step S61: Determine that the communication protocol is the protocol for communicating with the target device.

[0113] Step S62: According to the upgrade steps indicated by the upgrade instructions in the upgrade instruction set, send the firmware unit data in the firmware data unit queue to the target device.

[0114] Step S63: After the data transmission in the firmware data unit queue is completed, an upgrade verification is performed based on the total package verification value. If the verification passes, an upgrade result is generated to indicate that the target device has been successfully upgraded.

[0115] like Figure 3 As shown, in one embodiment, step S62, which involves sending firmware unit data from the firmware data unit queue to the target device according to the upgrade steps indicated by the upgrade instructions in the upgrade instruction set, includes:

[0116] Step S621: Take a firmware data unit from the head of the firmware data unit queue.

[0117] In the application, the firmware data unit queue is implemented as a queue-like data structure with the characteristics of First In First Out (FIFO). The data at the head of the queue is the oldest data that has been enqueued, and the data at the tail of the queue is the newest data that has been enqueued. Each time, a firmware data unit is taken from the head of the queue until the queue is empty.

[0118] Step S622: Send the firmware data unit to the target device.

[0119] In this application, before sending firmware data units to the target device, the operating conditions of the target device are checked to determine whether the current operating conditions of the target device meet the conditions for firmware upgrade or meet the conditions that prohibit firmware upgrades. For example, firmware upgrades are prohibited when the target device's battery level is below 5%, the battery is at high or low temperatures, the battery is being charged at high power, the voltage is unstable, or the current is abnormal.

[0120] Step S623, in case that the target device sends the acknowledgement information based on the firmware data unit, update the upgrade progress.

[0121] In application, the target device generates the check code based on the firmware block in the received firmware data unit and the algorithm required for the firmware block check, such as the cyclic redundancy check, and sends the acknowledgement information (ACK, Acknowledgement) if the check code is equal to the block check code of the firmware block, which means that the firmware block in the firmware data unit passes the check, and updates the upgrade progress.

[0122] Step S624, in case that the firmware data unit queue is not empty, return to the step S621 to take out a firmware data unit from the head of the firmware data unit queue.

[0123] Step S625, in case that the firmware data unit queue is empty, send the end identifier to the target device.

[0124] The step S63, after the data transmission in the firmware data unit queue is completed, perform the upgrade check based on the total package check value, and generate the upgrade result for indicating the upgrade success of the target device if the check passes, including:

[0125] Step S631, receive the complete check code sent by the target device based on the end identifier.

[0126] In application, after receiving the end identifier, the target device forms a complete firmware data package by using the firmware data in all the received firmware data units, and generates the integrity check code of the firmware data package according to the integrity check algorithm.

[0127] Step S632, in case that the complete check code is equal to the total package check value, generate the upgrade result for indicating the upgrade success of the target device.

[0128] In application, the check of each firmware block is realized by the block check code, and the check of the complete firmware data package formed by all the firmware blocks received by the target device is realized by the integrity check code and the total package check value, which guarantees the reliability and safety of the firmware data for upgrade.

[0129] Step S633, in case that the complete check code is not equal to the total package check value, generate the upgrade result for indicating the upgrade failure of the target device.

[0130] It should be understood that the size of the serial number of each step in the above embodiments does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
