  init.lua 是你的朋友 . 请参阅https://nodemcu.readthedocs.io/en/latest/en/upload/#initlua的完整文档 .

  -- load credentials, 'SSID' and 'PASSWORD' declared and initialize in there
  dofile("credentials.lua")
  
  function startup()
      if file.open("init.lua") == nil then
          print("init.lua deleted or renamed")
      else
          print("Running")
          file.close("init.lua")
          -- the actual application is stored in 'application.lua'
          -- dofile("application.lua")
      end
  end
  
  print("Connecting to WiFi access point...")
  wifi.setmode(wifi.STATION)
  wifi.sta.config(SSID, PASSWORD)
  -- wifi.sta.connect() not necessary because config() uses auto-connect=true by default
  tmr.alarm(1, 1000, 1, function()
      if wifi.sta.getip() == nil then
          print("Waiting for IP address...")
      else
          tmr.stop(1)
          print("WiFi connection established, IP address: " .. wifi.sta.getip())
          print("You have 3 seconds to abort")
          print("Waiting...")
          tmr.alarm(0, 3000, 0, startup)
      end
  end)
  

  Update

  wifi.sta.config 的当前语法如下：

  station_cfg={}
  station_cfg.ssid=SSID
  station_cfg.pwd=PASSWORD
  wifi.sta.config(station_cfg)
