micropython 实现wifi联网更新main代码

boot.py代码如下: 

# This file is executed on every boot (including wake-boot from deepsleep)

# 功能:联手机热点上网并获取gitee上最新文件替换esp32上的main.py

import network

import urequests

wlan = network.WLAN(network.STA_IF)

wlan.active(True)

def do_connect():

    if not wlan.isconnected():

        print('connecting to network...')

        wlan.connect('手机热点名', 'WIFI密码')

        while not wlan.isconnected():

            print('connecting to network failed...')

    print('network config:', wlan.ifconfig())

do_connect()

url="https://gitee.com/tianyudi/esp32/raw/master/webpush/main.py"

data=urequests.get(url,).content

if chr(data[9])=="1":

    # 如果main.py第十个字符为1，说明需要更新

    with open(r"main.py", "wb") as f:

        print("开始更新")

        f.write(data)

else:

    print("不更新")
