esp32之micropython 配网代码
最近学习esp32的时候想着能不能给设备自动配网，查了下网上有smartconfig配网但是我无法配置成功所以自己写了AP配网。
AP配网代码
import network
import socket,json
from machine import Pin, Timer
import time
led_pin = Pin(4, Pin.OUT)
# 配置热点模式
AP_SSID = 'myqiu_Setup'
AP_PASSWORD = 'setup123'
# Captive portal的HTML页面

重命名为AP.py 在你项目需要联网前引入代码即可
