Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
As described in the background section, when upgrading the firmware of the portable printer, the portable printer is usually connected to a computer through a data line, and a user needs to install an upgrade management program provided by a manufacturer of the portable printer on the computer, then the user downloads a latest version of firmware file from a server by operating the upgrade management program, and finally, the upgrade of the firmware of the portable printer is completed by operating the upgrade management program. The upgrade process is relatively complex and cumbersome, so that a user cannot upgrade the firmware of the portable printer in time and conveniently.
Even more, in some cases, the user cannot perform firmware upgrade of the portable printer himself or herself, and must rely on the help of others, which further complicates the upgrade process and may even affect the daily use of the portable printer. For example, a portable printer is used for printing an electronic receipt in daily work of a courier at present, when firmware of the printer needs to be upgraded, the courier needs to connect the portable printer with a computer in a wired mode for corresponding operation, however, some couriers may not have computers at home or cannot perform corresponding upgrading operation due to reasons such as age, and at the moment, the couriers need to post the portable printer to a company service station for unified upgrading through express delivery, which may cause that printing operation cannot be performed during upgrading, and daily work of the couriers is seriously affected.
Based on the above problems, in consideration of the fact that mobile intelligent terminals such as smart phones are very popular and are easier to operate than computers at present, the present application provides a scheme for upgrading firmware of portable printers based on mobile intelligent terminals, and the scheme establishes bluetooth connection between the mobile intelligent terminals and the portable printers, so as to replace computers as operation terminals for firmware upgrading.
It should be noted that, a bluetooth function is usually built in a portable printer in the market at present, and the bluetooth function is designed for facilitating connection between the portable printer and other intelligent devices, so that in the scheme described in the application, the portable printer itself does not need to be improved.
The following examples are intended to illustrate specific embodiments of the present application.
Example one
Referring to fig. 1, fig. 1 is a firmware upgrading method for a portable printer, which is shown in an embodiment of the present application, where the method is applied to a mobile intelligent terminal, an execution subject of the method may be the mobile intelligent terminal or a functional module based on software and/or hardware inside the mobile intelligent terminal, for example, the mobile intelligent terminal may be a smart phone or a tablet computer, and correspondingly, the execution subject of the method may be an APP in the smart phone or a software program in the tablet computer. For convenience of explanation and understanding, the following steps are described in detail by taking a smartphone and a smartphone APP as examples.
As shown in fig. 1, the method comprises the steps of:
s101: acquiring the current version number of the firmware of the portable printer, and acquiring the latest version number of the firmware of the portable printer of the corresponding model from the server; the portable printer is connected with the mobile intelligent terminal through Bluetooth;
as a possible implementation, the specific process of this step may be: when a user wants to determine whether the firmware of the portable printer has a new version, the Bluetooth connection between the smart phone and the portable printer can be established, then a corresponding firmware upgrading APP in the smart phone is opened, and at the moment, the APP automatically acquires the model of the connected portable printer and the version number of the firmware.
Further, the step of acquiring the latest version number of the firmware of the portable printer of the corresponding model from the server may be: and acquiring an inquiry instruction triggered by a user, and acquiring the latest version number of the firmware of the portable printer of the corresponding model from the server based on the inquiry instruction. In specific implementation, an inquiry key (virtual key) can be set in the APP, and when a user presses the inquiry key, the APP automatically inquires the latest version number of the firmware corresponding to the model from the server based on the acquired model of the portable printer.
S102: judging whether the current version number is consistent with the latest version number;
s103: if the judgment result is inconsistent, downloading the firmware file corresponding to the latest version number from the server;
in specific implementation, the steps may be: downloading a firmware file corresponding to the latest version number from a server based on default setting; or acquiring a downloading instruction triggered by a user, and downloading the firmware file corresponding to the latest version number from the server based on the downloading instruction.
The default setting refers to that a user can perform corresponding setting in the APP in advance, for example, when it is determined that the current version number is inconsistent with the latest version number and the smart phone is connected to the WIFI, the user automatically starts to download the firmware file corresponding to the latest version number from the server. The downloading based on the downloading instruction triggered by the user may be similar to the query function in the above step, that is, the downloading is performed when the user presses a corresponding key (virtual key) in the APP.
S104: and based on the user instruction, sending the downloaded firmware file to the portable printer through Bluetooth, so that the portable printer upgrades the firmware based on the received firmware file.
Specifically, the principle of upgrading the firmware of the portable printer based on the mobile intelligent terminal is consistent with the principle of upgrading based on a computer, the upgrading is realized based on programs, and in the specific implementation, the corresponding programs are transplanted among different systems, so that the details are not described.
After the firmware file is downloaded, the user can trigger the upgrading instruction through the keys in the APP, and the APP sends the firmware file to the portable printer after receiving the corresponding instruction, so that the firmware of the portable printer is upgraded. Accordingly, before step S104, the method further includes: and sending first prompt information to the user after the firmware file is downloaded so as to prompt the user to upgrade the firmware of the portable printer based on the downloaded firmware file. For example, after the firmware is downloaded, a prompt message of "download complete" is displayed on the original download interface, and after the user sees the prompt message, the user can press a preset "start upgrade" button, and at this time, the user is considered to trigger the upgrade instruction. For another example, after the firmware is downloaded, a pop-up box is triggered, the pop-up box displays the contents of "file downloading is completed and whether upgrading is performed immediately", yes and no or similar virtual keys are provided, and when the user presses "yes", the user is considered to trigger the upgrading instruction.
In addition, the firmware upgrading process lasts for a period of time, and once the portable printer is interrupted due to power failure in the upgrading process, the firmware of the portable printer is damaged, so that the portable printer cannot be normally used, and a user cannot repair the portable printer by himself or herself and must return to a factory for repair. Therefore, in order to avoid the above-mentioned unexpected situation, before step S104, the method may further include: and sending a second prompt message to the user after the downloading of the firmware file is completed so as to prompt the user to ensure that the residual electric quantity of the portable printer is enough to complete the upgrading of the firmware of the portable printer, and/or prompt the user to connect the portable printer with a power supply.
Furthermore, in some embodiments, the method further comprises: after the information of successful upgrade sent by the portable printer is acquired, the model of the portable printer and the version number of the firmware subjected to firmware upgrade are stored locally, so that a fourth prompt message is sent to the user after the firmware version of the portable printer of the corresponding model is acquired next time and is updated, and the user is prompted that the firmware of the portable printer of the corresponding model has a new version.
Specifically, after the firmware upgrade of portable printer succeeds, cell-phone APP can be saved corresponding model and firmware version number locally, so set up, whether the firmware that wants to know portable printer after user's a period has the update, only need open cell-phone APP look over can, that is, because the model that keeps portable printer and the version number of firmware in the cell-phone APP, consequently need not to acquire through the bluetooth again, it is corresponding, the user only need inquire according to the model of saving locally, and carry out the comparison with the version number of inquiry result and local can. More specifically, after the firmware upgrade is completed, when the user starts the mobile phone APP again, the mobile phone APP automatically performs query and comparison based on the stored model, and displays the comparison result to the user in forms such as text prompt, so that the user can know the comparison result in time.
The technical scheme provided by the embodiment of the application can have the following beneficial effects:
according to the technical scheme, the mobile intelligent terminal is connected with the portable printer based on the Bluetooth function of the portable printer, so that the model and the version number of the firmware of the portable printer are obtained, the latest version number of the firmware of the portable printer of the model is obtained from the server through the mobile intelligent terminal, if the current version of the firmware of the portable printer is not the latest version, the latest version of the firmware file is directly downloaded through the mobile intelligent terminal, and the upgrading of the firmware of the portable printer is completed based on the mobile intelligent terminal. So set up, for traditional carrying out firmware upgrading based on the computer, the upgrading equipment that uses is more common, the operation degree of difficulty is lower, the upgrading process is more convenient to the user can upgrade the firmware of portable printer more in time, conveniently.
