Referring to fig. 1, firmware upgrade refers to upgrading firmware in the home device 13, where the home device refers to an intelligent home device, and the intelligent home device includes a processor, a memory, and so on, and some intelligent home devices may also install an Application (APP).
The mobile terminal 11 may be a terminal device such as a smart phone, a tablet computer, a super mobile personal computer (Ultra-mobile Personal Computer, UMPC), a netbook, a personal digital assistant (Personal Digital Assistant, PDA), etc., but is not limited thereto.
The communication device 12 is composed of hardware and software, an application program interface of the software can be called by the mobile terminal 11, and after the application program interface is called by the mobile terminal 11, the mobile terminal 11 and the communication device can realize communication. For individual household appliances 13, the communication device 12 may be integrated on the individual household appliance 13 and communicate with the household appliance 13 (not shown in the figure); for the application scenario of the internet of things, the communication device 12 may be independently disposed outside the home appliance 13, or the communication device 12 may be integrated on a certain home appliance 13, and the communication device 12 may communicate with two or more home appliances 13.
The communication device 12 may communicate with the mobile terminal 11 through WiFi, zigBee, bluetooth, or the like, and the communication device 12 may communicate with the home appliance 13 through bluetooth.
Fig. 2 is a schematic diagram of a method for firmware upgrade provided by an embodiment of the present disclosure, with which the embodiment of the present disclosure is executed by the communication device shown in fig. 1, for exemplary illustration. The communication apparatus may include a middleware SDK, a FOTA module, an M2M module, and a device interaction SDK, the middleware SDK being configured with a first interface and a second interface (application program interface), and the first interface and the second interface being callable by the mobile terminal.
As shown in connection with fig. 2, the method for firmware upgrade includes:
s201, under the condition that the first interface is called by the mobile terminal, remote firmware version information is obtained through a middleware SDK, a FOTA module, an M2M module and a device interaction SDK, a judging result of whether upgrading is needed or not corresponding to the remote firmware version information is obtained, and the middleware SDK sends the judging result to the mobile terminal through the first interface.
For example, before using the home appliance (for example, the intelligent washing machine) or after using the home appliance (for example, the intelligent washing machine), the user operates the mobile terminal, and the mobile terminal responds to the operation of the user and invokes the first interface; or after the home appliance is started or before the home appliance is shut down, the first interface is automatically called; alternatively, the first interface is invoked once every set period of time, such as a week, a half month, a month, or more.
After the first interface is called by the mobile terminal, the communication device obtains a judging result of whether the household electrical appliance needs to be upgraded or not and returns the judging result to the mobile terminal through the first interface, so that a user can know whether the household electrical appliance needs to be upgraded or not through the mobile terminal, and is convenient for the user to determine whether the household electrical appliance is used at the moment or when the household electrical appliance is used according to the length required by upgrading the firmware of the household electrical appliance.
In some application scenarios, the first interface (e.g., an application program interface named checkFOTA) may provide a callback function as an entry, and the detection result is returned in the callback function, for example, the detection result may include an int value: the resultCode, different code values indicate different states of the home device, e.g., two codes may be returned, indicating no need for upgrades and upgradeability, respectively.
Alternatively, three codes may be returned, representing no upgrades, being upgraded, and being upgradeable, respectively.
In some application scenarios, the middleware SDK further returns an id object to the mobile terminal through the first interface, which indicates a specific description of the returned result, for example, the user indicates the intelligent washing machine in the id object, and the determination result is upgradeable, so that the intelligent washing machine can be indicated to be upgradeable.
In some application scenarios, the middleware SDK further returns a pool value to the mobile terminal through the first interface, where the pool value is used to indicate success or failure of the call result, where true indicates success of the call, and false indicates failure of the call. In the case that the call result is true, the first interface may return two or three codes representing the determination result, and in the case that the call result is false, the first interface returns a code representing an error code.
The callback function of the first interface may execute asynchronously so that the main thread is not blocked.
Optionally, obtaining remote firmware version information includes: the middleware SDK establishes connection with the device interaction SDK to obtain device version information sent by the household electrical appliance and received by the device interaction SDK; the middleware SDK updates the equipment version information to the M2M module; the M2M module sends the equipment version information to the FOTA module; the middleware SDK inquires the remote firmware version information corresponding to the equipment version information from the FOTA module. Thus, remote firmware version information is obtained.
In the embodiment of the present disclosure, the action performed by the mobile terminal may be an action performed by an APP installed on the mobile terminal; the action performed by the home device may be an action performed by an APP installed on the home device.
The middleware SDK can query the version server for the local firmware version information of the household appliance, after the middleware SDK obtains the local firmware version information and the remote firmware version information, a judgment result without upgrading is obtained under the condition that the version number of the local firmware version information is higher than or equal to the version number of the remote firmware version information, and a judgment result capable of upgrading is obtained under the condition that the version number of the local firmware version information is lower than the version number of the remote firmware version information.
Specifically, the middleware SDK may query the version server for the local firmware version information of the home appliance through a hypertext transfer protocol (Hypertext Transfer Protocol, HTTP), or query the version server for the local firmware version information of the home appliance through a hypertext transfer security protocol (Hyper Text Transfer Protocol over SecureSocket Layer, HTTPs).
If the judging result is upgradeable, before the middleware SDK sends the upgrade instruction to the device interaction SDK, the method for firmware upgrade can further comprise: the middleware SDK downloads a firmware upgrade package at the resource server. The middleware SDK can download a firmware upgrade package in the resource server after sending the judging result to the mobile terminal through the first interface; or, the middleware SDK may first download the firmware upgrade package in the resource server, and then send the judgment result to the mobile terminal through the first interface in the downloading process.
The middleware SDK can download the firmware upgrade package on the resource server through HTTP, and the middleware SDK can also download the firmware upgrade package on the resource server through HTTPS.
The firmware upgrade package is downloaded before the middleware SDK sends the upgrade instruction to the device interaction SDK, so that the firmware upgrade process after the middleware SDK sends the upgrade instruction to the device interaction SDK is facilitated.

And the upgrade progress is sent to the middleware SDK by the device interaction SDK.
Under the condition that the judging result is upgradeable, the mobile terminal can be operated by a user, and the mobile terminal responds to the user operation and calls the second interface; or under the condition that the mobile terminal receives the judging result of being upgradeable, the mobile terminal automatically calls the second interface to upgrade the household electrical appliance.
After the second interface is called by the mobile terminal, the equipment interaction SDK in the communication device interacts with the household electrical equipment, the household electrical equipment enters an upgrading mode and carries out firmware upgrading in the interaction process, the equipment interaction SDK sends the upgrading progress to the middleware SDK, and the middleware SDK feeds back the upgrading progress to the mobile terminal through the second interface, so that a user can know the upgrading progress of the household electrical equipment through the mobile terminal, and the user can conveniently decide when to use the household electrical equipment according to the firmware upgrading progress of the household electrical equipment.
In some application scenarios, the second interface (e.g., an application program interface named startFOTA) may provide three callback functions as entries, the first callback function returning to the upgrade progress, e.g., the first callback function may return an int value, with the int value indicating the upgrade progress; the second callback function returns a successful upgrade result, for example, the second callback function may return a bool value to indicate the successful upgrade result by true; the third callback function returns the upgrade failure result, for example, the third callback function may return a bool value to indicate the upgrade failure result as true.
The callback function of the second interface may execute asynchronously so that the main thread is not blocked.
The middleware SDK feeds back the upgrading progress to the mobile terminal through the second interface, so that a user can know the upgrading progress through the mobile terminal. In addition, the middleware SDK can also feed back the upgrade progress to the FOTA module so as to share the upgrade progress, and other equipment can inquire the upgrade progress set to the household appliance through the FOTA module.
The communication device can send firmware version information to the mobile terminal through the first interface so that a user can know whether equipment (household electrical equipment) needs to be upgraded or not, and in the upgrading process, the communication device can feed the upgrading progress back to the mobile terminal through the second interface so that the user can know the time of upgrading completion and the time when the equipment can be used continuously, the user can arrange the time reasonably conveniently, meaningless waiting processes are reduced, and the use experience of the user is improved.
In addition, whether the upgrading and the upgrading progress are needed or not is fed back to the user through two interfaces (a first interface and a second interface), so that the mobile terminal can be conveniently called.
In practical application, after the firmware of the home appliance is upgraded, the home appliance is restarted and re-registered to the intelligent home system.
