Embodiment 1

[0059] figure 1 The implementation flow of the accessory upgrading method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0060] In step S101, the firmware of the accessory is stored in the mobile terminal.

[0061] Accessories are usually realized by Micro Controller Unit (MCU), and the memory of MCU is generally small (only 2k byte or 4k byte), so most accessories do not have wireless fidelity WIFI function, and there is no perfect file system, therefore, accessories cannot download firmware through WIFI to complete the upgrade locally like a mobile terminal, nor can they copy firmware at will like a memory card.

[0062] In view of the above-mentioned limitations of the accessory itself, in the embodiment of the present invention, the firmware of the accessory is first stored in the memory card of the mobile terminal, and then the mobile terminal and the accessory are connected through a USB cable or an OTG adapter and a USB ca...

Embodiment 2

[0094] Figure 5 It shows the implementation process of the accessory upgrading method provided by Embodiment 2 of the present invention, and the details are as follows:

[0095] The second embodiment is carried out on the basis of the first embodiment. In order to ensure that the firmware sent by the mobile terminal in the first embodiment is accurately burned into the accessory, it is necessary to verify the firmware in the upgraded accessory. If the verification is not passed, then the upgrade operation will not be performed, and if it fails, it is necessary to call step S103 in the first embodiment to perform the upgrade operation on the accessories again. Specifically, the verification process includes the following steps:

[0096] In step S501, the mobile terminal sends a firmware read request command to the accessory, notifying the accessory to wait for receiving the read address.

[0097] Specifically, the mobile terminal sends a read address READ_CMD command to the ...

Embodiment 3

[0107] Figure 6 A specific structural block diagram of the mobile terminal provided by Embodiment 3 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown. After the mobile terminal 6 is plugged into the OTG interface, it is connected to the accessory through a USB cable, or the mobile terminal 6 is connected to the accessory through a USB cable to form a system for upgrading the accessory through the mobile terminal, and the mobile terminal sends the firmware of the accessory stored locally to the accessory , the upgrade of accessories is completed, the mobile terminal 6 includes: CPU61, and a transfer switch 62 connected to the CPU, through which the OTG adapter connected to the mobile terminal 6 or connected to the mobile terminal 6 The D+ / D- of the USB cable is connected with the i2c / uart of the CPU61.

[0108] Described mobile terminal 6 also comprises:

[0109] A firmware storage u...

Abstract

The invention is applied to the technical field of upgrading, and provides a method and a system for upgrading a fitting by virtue of a mobile terminal, and the mobile terminal. The mobile terminal comprises a CPU (central processing unit) and a changeover switch connected with the CPU, wherein an OTG (On-The-Go) adapter connected with the mobile terminal or the D+/D- of a USB (universal serial bus) connected with the mobile terminal is connected with the i2c/uart (inter-integrated circuit/universal asynchronous receiver/transmitter) of the CPU through the changeover switch. The method comprises the following steps that the firmware of the fitting is stored in the mobile terminal; the mobile terminal establishes connection with the fitting; the mobile terminal transmits the firmware to the fitting through the OTG adapter and the D+/D- of the USB connected with the OTG adapter according to an i2c/uart protocol; or the mobile terminal transmits the firmware to the fitting through the D+/D- of the USB according to the i2c/uart protocol. According to the method, the system and the mobile terminal, if a serious bug appears or the fitting is subsequently required to be added with a new function after the fitting is released, the firmware can be locally upgraded by a user by virtue of the mobile terminal, the fitting is not required to be returned to a manufacturer, and the mobile terminal is simple and portable.

Description

technical field [0001] The invention belongs to the technical field of upgrading, and in particular relates to a method, a system and a mobile terminal for upgrading an accessory through a mobile terminal. Background technique [0002] With the popularity of smart mobile terminals, various accessories have sprung up, such as fast charging adapters, power banks, health bracelets, smart glasses and so on. [0003] Since the storage space of accessories is generally small, most of them do not have wireless fidelity WIFI function, and they do not have a complete file system and cannot store files, so they cannot be uploaded via Over-the-Air Technology (OTA) like mobile terminals. Accessories are upgraded. If you encounter a major bug or need to add new functions, you can only return to the factory. The manufacturer will disassemble the accessory, put the circuit board of the accessory on the jig, and use specific tools to upgrade the firmware of the chip inside the circuit boar...
