esp32的wifi连接与esp8266的有区别；

wifi

ESP8266 and ESP32 differ a lot:

ESP8266

• events are captured via wifi.eventmon.*:
  • wifi.eventmon.register(event[, function(T)])
    • wifi.eventmon.STA_CONNECTED
    • wifi.eventmon.STA_DISCONNECTED
    • wifi.eventmon.STA_AUTHMODE_CHANGE
    • wifi.eventmon.STA_GOT_IP
    • wifi.eventmon.STA_DHCP_TIMEOUT
    • wifi.eventmon.AP_STACONNECTED
    • wifi.eventmon.AP_STADISCONNECTED
    • wifi.eventmon.AP_PROBEREQRECVED

ESP32:

• events are captured via wifi.on()
  • wifi.ap.on(event, callback)
    • event:
      • start: no additional info
      • stop: no additional info
      • sta_connected: information about the client that connected:
      • mac: the MAC address
      • id: assigned station id (AID)
      • disconnected: information about disconnecting client
      • mac: the MAC address
      • probe_req: information about the probing client
      • from: MAC address of the probing client
      • rssi: Received Signal Strength Indicator value

 ESP32的WiFi函数

我只列出esp32的代码

print("系统启动了")

gpio.config({
    gpio=2,
    dir=gpio.OUT
})

gpio.write(2,1)

print("设置wifi工作模式  连接到WiFi路由器时")
wifi.mode(wifi.STATION,true)

print("启动wifi")
wifi.start()

print("连接访问点(将配置保存到flash中)")
station_cfg={}
station_cfg.ssid="xz220"
station_cfg.pwd="www.kyhmy.com"
wifi.sta.config(station_cfg, true)

print("连接")
wifi.sta.connect()

print("获取MAC")
print(wifi.sta.getmac())

比较有意思的是，我没有发现获取IP的方法，可能是官方取消了

只能登陆路由器查看板子获取到的ip地址了

我给板子绑定了固定ip这样就不会来回变了；
