Embodiment Construction
[0033] The present invention provides a method and system for an Android system compatible wifi chip. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] Such as figure 1 A kind of Android system compatible wifi chip method shown, wherein, described method comprises the following steps:
[0035] S100. Read the identification number of the wifi chip, and save the read identification number in the system directory to form a system node.
[0036] The above steps are specifically: read the identification number of the wifi chip through the main system interface, use the read identification number to create a system node in the system directory, and store the read wifi chip identification number in the sy...

The invention discloses a method and system for enabling the Android system to be compatible with a wifi chip. The method for enabling the Android system to be compatible with the wifi chip comprises the steps that (A) the identification number of the wifi chip is read, and the read identification number of the wifi chip is stored in a system directory so that a system node can be formed; (B) a wifi is started, the identification number, in the system node, of the wifi chip is read by the system, a preset defined function of a chip driver corresponding to the identification number of the wifi chip is executed according to the identification number of the wifi chip, and then the chip driver corresponding to the identification number of the wifi chip is obtained; (C) the chip driver which is obtained is loaded. By the adoption of the method and system for enabling the Android system to be compatible with the wifi chip, dynamic loading of the wifi driver is achieved so that equipment can be compatible with wifi chips with different specifications and can be matched with various wifi chips under the condition that the code of the equipment is not changed, the research and development efficiency is improved, and maintenance of a software version is accelerated.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for an Android system compatible wifi chip. Background technique [0002] With the development of electronic technology and the popularization of networks, more and more devices have Internet access functions, especially wireless Internet access is more and more widely used. At present, the wireless network basically adopts 3G and wifi. [0003] At present, the process of loading wifi in the Android system is roughly as follows: click to open wifi on the application interface, the interface application calls the setWifiEnabled (wifiEnabled) interface, sends the command to open wifi, and sends CMD_LOAD_DRIVER to call the driver loading function to load the driver. At this point, load the required driver by loading the wifi layer interface. The above process is implemented in the wifi.c code of the android hal layer. In wifi.c, the wifi_load_driver fun...
