【Micropython esp32/8266】AP模式下网页点灯控制示例


⛳#### 前面一篇是关于STA模式下网页控制,本次带来的是Micropython设备作为AP模式下,去访问设备,并控制点灯程序。

🎯建立AP模式

ap_ssid = "ESP8266AP"# 热点信号名称
ap_password = "12345678"#密码
ap_authmode = 3  # 加密方式;WPA2
 
wlan_ap = network.WLAN(network.AP_IF)
wlan_ap.active(True)
wlan_ap.config(essid=ap_ssid, password=ap_password, authmode=ap_authmode)

📝主程序代码

'''
    authmode模式:
  AUTH_OPEN -- 0
  AUTH_WEP -- 1
  AUTH_WPA_PSK -- 2
  AUTH_WPA2_PSK -- 3
  AUTH_WPA_WPA2_PSK -- 4
'''
import usocket as socket
import network
from machine import Pin
ap_ssid = "ESP8266AP"
ap_password = "12345678"
ap_authmode = 3  # WPA2
 

wlan_ap = network.WLAN(network.AP_IF)

wlan_ap.active(True)
wlan_ap.config(essid=ap_ssid, password=ap_password, authmode=ap_authmode)

print('Connect to WiFi ssid ' + ap_ssid + ', default password: ' + ap_password)
print('and access the ESP via your favorite web browser at 192.168.4.1.')
#print('Listening on:', addr)

led = Pin(2, Pin.OUT)

def web_page():
  if led.value():
    gpio_state="OFF"
  else:
    gpio_state="ON"

  return html

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', 80))
s.listen(5)

while True:
  conn, addr = s.accept()
  print('Got a connection from %s' % str(addr))
  request = conn.recv(1024)
  request = str(request)
  print('Content = %s' % request)
  led_on = request.find('/?led=on')
  led_off = request.find('/?led=off')
  if led_on == 6:
    print('LED ON')
    led.value(0)
  if led_off == 6:
    print('LED OFF')
    led.value(1)
  response = web_page()
  conn.send('HTTP/1.1 200 OK\\n')
  conn.send('Content-Type: text/html\\n')
  conn.send('Connection: close\\n\\n')
  conn.sendall(response)
  conn.close()

⛳连接和访问

📍程序运行后,通过电脑或手机连接micropython设备的WiFi。

  • 📌Shell调试窗口将打印被连接上的设备IP地址
  • 接下来解释通过浏览器访问micropython设备网关地址,进行设备引脚控制。
