RTL8723BS WIFI部分源码下载

硬件电路如下，这不就是SD卡标准接口么？！！
这里写图片描述

加载驱动会看到以下调试信息，说明已经成功驱动了，否则就要各种查查查，如果人品不行的就到庙里多烧烧香(看个人信仰)！

其中wpa_supplicant.conf 配置文件格式，可自行网上查wpa_supplicant工具用法

ctrl_interface=/var/run/wpa_supplicantnetwork={        ssid="热点名称"        psk="热点的密码"        key_mgmt=WPA-PSK        proto=WPA2        pairwise=CCMP        group=CCMP}

还有几个wifi调试工具
比如iwlist扫描附近有哪些显摆的热点：
