Problems solved by technology
If one device has the upgrade resources needed by another device, but cannot be connected to the Internet, the upgrade resources may be transmitted between the two devices through Bluetooth or infrared technology, but when the two devices are far apart, Bluetooth or infrared The short-distance transmission technology will not be able to play a role, even if it is copied through the medium, it will be troublesome. At this time, there is an urgent need for a convenient upgrade method that does not require networking to upgrade the software in the device.

Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] WiFi Direct is a P2P transmission technology based on 802.11. When there is no WiFi hotspot nearby, two devices supporting 802.11 can be interconnected through the WiFi Direct protocol. It supports a variety of WiFi devices, including computers, mobile phones, game consoles, digital cameras, webcams, printers, keyboards, headsets, and more. Devices that meet this standard can easily achieve direct connection with other devices, transmit data or share applications without the need for hotspot base stations, routers or APs, and the data transmission speed is fast.

The invention discloses a software upgrading method and system based on WiFi Direct, by presetting the menu items for software upgrading through the WiFi Direct function and the sub-menu items for sending upgrade software requests; the main mobile device receives the user's operation instructions for the menu items , enable the WiFi Direct function, search for the slave mobile device with the WiFi Direct function, and perform a match. If the match is successful, it will receive the user's operation instruction for the submenu item, and send a software upgrade request to the slave mobile device; the slave mobile device will comply with the upgrade The upgrade file requested by the software is sent to the main mobile device; the main mobile device performs software upgrade according to the upgrade file, which realizes the function of obtaining upgrade resources between mobile devices for software upgrade when there is no network and no WiFi hotspot. The search range is large and the upgrade The file transfer speed is fast and the reliability is high, greatly reducing the upgrade time.
Description
technical field [0001] The present invention relates to wireless transmission technology, in particular to a software upgrading method and system based on WiFi Direct technology. Background technique [0002] Conventional software upgrade methods include two methods of upgrading software from a local storage device and an upgrade package downloaded from a network. One of these two methods must have a local storage device, and the other must be connected to the network. If one device has the upgrade resources needed by another device, but cannot be connected to the Internet, the upgrade resources may be transmitted between the two devices through Bluetooth or infrared technology, but when the two devices are far apart, Bluetooth or infrared The short-distance transmission technology will not be able to play a role, even if it is copied through the medium, it will be troublesome. At this time, there is an urgent need for a convenient upgrade method that does not require netwo...
