FIG. 1 is a schematic flow chart provided by the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Referring to the attached drawing 1, the method for dynamically compatible with WIFI and Bluetooth modules of different manufacturers based on the android system provided by the invention comprises the following specific steps:
s1, starting a teconfi in a system init.xxxx.rc to scan a usb bus on the equipment, and acquiring all VID/PID on the equipment;
further, starting a teconfi program, accessing a USB file system (/ sys/bus/USB/devices), and reading PID and VID information of all devices on the USB through a specific program;
s2, reading a WIFI configuration file stored on a setting storage medium, obtaining and comparing the vid _ pid of a configured WIFI/BT module with the result obtained by scanning S1, if the vid _ pid is the same as the VID _ pid, obtaining a WIFI _ vendor _ name corresponding to the vid _ pid, and setting the attribute of the WIFI _ vendor _ name in the rop;
further, analyzing a wifi.cfg file stored in the vendor/etc/wifi/through a specific program, comparing the read PID and VID through the specific program with the VID _ PID preset on the equipment, and if the PID and VID are the same as the VID _ PID, saving the wifi _ vendor _ name to the vendor.mtk.wifi.driver of the system prop;
s3, identifying a WIFI/Bluetooth module manufacturer according to WIFI _ driver _ name, setting WIFI to be loaded, and setting wpa _ supplied and libbt-driver.so as to and libblluetool.so as to load/Bluetooth modules, wherein for example, WIFI/Bluetooth of Mediatek uses wpa _ supplied _ mtk libbt-driver _ mtk.so as to use WIFI/Bluetooth of reader-stored in a medium in advance, and uses wpa _ supplied _ rtk libbt-driver _ rtk.so as to load/bluetooth modules;
furthermore, wpa _ coupon _8_ lib provided by different manufacturers WIFI/BT are built into a system and are compiled into wpa _ coupon respectively, and then are renamed respectively, for example, the rename of media is wpa _ coupon _ mtk, the rename of media is built into the wpa _ coupon _8_ lib provided by Realtek is renamed into wpa _ coupon _ rtk compiled by the system and is stored into/vendor/bin/hw, wherein WIFI _ vendor _ name is analyzed through a specific program, in the example, only a vendor containing MT is considered as a mediatek, a vendor containing RTL is considered as a Realtek, and in some examples, a vendor can be added into a configuration file to distinguish the vendor;
if the WIFI/BT module is a WIFI/BT module of Mediatek, configuring wpa _ supplicant, libeluetoth.so-vendor.so as to use wpa _ supplicant _ mtk and libeluetoth mtk.so-library _ vendor _ mtk.so as to use wpa _ supplicant _ mtk and libeluetoth _ vendor _ mtk.so if the WIFI/BT module of Realtk, configuring wpa _ supplicant, libeluetoth.so-vendor.so as to use wpa _ supplicant _ rtk and libeluetoth _ rtk.so-library-vendor _ rtk.so as to use wpa _ supplicant _ rtk and libeluetoth _ rtk.so-library;
s4, loading the corresponding drive of the wifi/Bluetooth module by utilizing on property, namely, vector, mtk, wifi and driver in init.rc;
further, in init.mt5862.rc different wifi/bt modules and different configurations are launched in response to on property in the init program of the system.
Further, in S1, a WIFI and bluetooth module configuration system before starting is further included, specifically, the configuration system specifically includes the following steps:
step 1: the configuration file wifi.cfg of the wifi/bluetooth module contained in the system is edited, and the format of the example is as follows:
＝＝＝＝＝
wifi_vendor_name＝MT7668STA
order＝9
count_vid_pid＝1
vid_pid＝0x0e8d:0x7668
wlan_fast_connect＝1
＝＝＝＝＝
wifi_vendor_name＝RTL8822CU
order＝11
count_vid_pid＝2
vid_pid＝0x0bda:0xc82e
vid_pid＝0x0bda:0xc82c
wlan_fast_connect＝0；
from the above, it can be seen that the VID _ PID represents the VID PID, the WIFI _ vendor _ name represents the WIFI/BT model, and we can know from the model that the 7668WIFI/BT module belongs to different vendors, such as MT7668STA represents Mediatek, RTL8822CU represents the 8822WIFI/BT module of RTL, and the VID _ PID can be obtained by lsusb (shell instruction);
step 2: compiling a plurality of WIFI/BT module drivers and storing the WIFI/BT module drivers into the vendor/lib/modules of the equipment, wherein the WIFI driver of RTL8822cu is 8822cu.ko, and the BT driver is rtk _ btusb.ko and is stored into the vendor/lib/modules of the equipment;
and step 3: the method comprises the steps that wpa _ submissions _8_ libs provided by WIFI/BTs of different manufacturers are built into a system and compiled to obtain wpa _ submissions respectively, and then renamed respectively, for example, the media is renamed to wpa _ submissions _ mtk, the wpa _ submissions _8_ libs provided by Realtek are built into the wpa _ submissions compiled by the system and are renamed to wpa _ submissions _ rtk, and the wpa _ submissions are stored in a/vendor/bin/hw/simultaneously;
and 4, step 4: putting a/system/BT protocol stack and a bdrid _ build cfg.h and a libbt-vendor provided by WIFI/BT of different manufacturers into a system to compile libbbelueton.so and libbt-vendor.so respectively, then naming the WIFI/BT of a Mediatek as libbbelueton _ rtm.so and libbt-vendor _ mtk.so.Realtek again, and storing the WIFI/BT of the Mediatek and libbbelt/vendor _ rtk.so respectively under the WIFI/BT protocol stack and the bdrid _ build cfg.h and libbt-vendor/lib;
and 5: at init.mt5862.rc, the corresponding module loader is added at the same time, as for example:
the using process of the invention is as follows: when the method is used, the teconfi is started in the init.xxxx.rc of the system to scan the usb bus on the equipment, and all VID/PID on the equipment are obtained;
reading a WIFI configuration file stored on a setting storage medium, obtaining and comparing the vid _ pid of a configured WIFI/BT module with the result obtained by scanning of S1, if the vid _ pid is the same as the VID _ pid, obtaining a WIFI _ vendor _ name corresponding to the vid _ pid, and setting the WIFI _ vendor _ name to the attribute of vendor.
Identifying a WIFI/Bluetooth module manufacturer according to WIFI _ driver _ name, setting to-be-loaded WIFI,/Bluetooth module wpa _ supplied and libbt-driver.so as to set the WIFI/Bluetooth module to be loaded, such as Mediatek WIFI/Bluetooth, using wpa _ supplied _ mtk libbt-driver _ mtk.so as to use libblluethoothmtk.so as to use wpa _ supplied _ rtk libbt-driver _ rtk.so as to set the WIFI/Bluetooth module to be loaded;
and loading the corresponding driver of the wifi/Bluetooth module by utilizing on property, a driver.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made in accordance with the technical solution of the present invention are within the scope of the claims of the present invention.
