Php 使用手机将raspberry pi连接到Wifi
我用的是覆盆子皮2模型B 我想通过手机将我的raspberry pi连接到检测到的wifi网络 在使用手机连接到raspberry pi后，我可以通过在url中输入ip地址来访问raspberry pi的web服务器 我目前能够在raspberry pi的web服务器上扫描检测到的wifi，如所示： 以及： 用于扫描wifi的Python代码：Php 使用手机将raspberry pi连接到Wifi,php,python,linux,raspberry-pi,raspberry-pi2,Php,Python,Linux,Raspberry Pi,Raspberry Pi2,我用的是覆盆子皮2模型B 我想通过手机将我的raspberry pi连接到检测到的wifi网络 在使用手机连接到raspberry pi后，我可以通过在url中输入ip地址来访问raspberry pi的web服务器 我目前能够在raspberry pi的web服务器上扫描检测到的wifi，如所示： 以及： 用于扫描wifi的Python代码： #!/usr/bin/env python import subprocess import re class line_matcher:
