公司有个项目需要手机同时打开wifi+4g
wifi链接专用设备, 4G与外网通信
(众所周知,手机打开wifi后,4g将自动关闭)
研发阶段用的 红米手机,通过如下方法能实现
adb命令:
挂载wifi网卡
insmod /system/lib/modules/wlan.ko
开启wifi网卡
netcfg wlan0 up
后台链接wifi
wpa_supplicant -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf -B
dhcp自动获取ip
dhcpcd wlan0
设置路由
ip route add 192.0.0.0/8 dev wlan0
临上线客户选用了mate s 手机,机子采购回来以后,先root然后adb执行如上命令,到wpa_supplicant -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf -B这句的时候
logcat显示

后面dhcp的就卡住不会执行了.....
看样子是没有链接上wlan
已经折腾了一周多了,google,baidu相关的资料很少.
有没有高手知道这个问题大概出在什么地方呢?求大师指条明路,
另外,华为机子里没有wifi模块/system/lib/modules/wlan.ko
但是关闭wifi后模块不会被卸载所以没有执行/system/lib/modules/wlan.ko,不知道有没有影响
