ESP8266 module name

Posted on
  • In any tutorial of using ESP8266 written that the module should be called like that

     var wifi = require("Wifi");

    But there is no Wifi.js in directory. And the terminal callback


    confirms that

    I assume that we need ESP8266WiFi.js, but the module crashes with

    WARNING: Parent must be an object - not a String, Integer, etc.
    Uncaught Error: Field or method "write" does not already exist, and can't create it on String

    in function "connect" called from line 4 col 1

    trying to complete a simple task

    var wifi = require("ESP8266WiFi");
    wifi.connect ("mySSID", {password:"myPWD"}, function (){
    console.log ("Connected to ap");
    wifi.setIP ({ip:"", gw:"", netmask:""}, function (){
    console.log ("Ip set");

    Function wifi.setIP is defined in reference but there is no such function in module.
    What I`m doing wrong?

  • Hi @Questdoino,

    Wifi and ESP8266 are internal modules.

    Please check ESP8266_WifiUsage to figure out how to use the module Wifi on ESPs.

  • Are you using the ESP8266 to provide WiFi to another device running Espruino, or are you running Espruino on the ESP8266 itself?

  • I`m trying to use it itself

  • Ok, start from the beginning. At last flashed boot 1.6 and 1.91 firmware but this code doesn`t work

    var wifi = require("Wifi");
    console.log ("START");
    wifi.connect ("mySSID", {password:"myPWD"}, function (){
    console.log ("Connected to ap");
    wifi.setIP ({ip:"", gw:"", netmask:""}, function (){
    console.log ("Ip set");

    ESP stays in default AP mode, doesnt connect to "mySSID" AP and cant find wifi.setIP function

    The IDE warns that Wifi module not found. Where is it located?

  • There is no setip function for the esp8266 wifi.

    var wifi = require("Wifi");
    wifi.connect("my-ssid", {password:"my-pwd"}, function(err){
      console.log("connected? err=", err, "info=", wifi.getIP());

    Use the code from the example page - the wifi ip will get echoed to the console..

  • Module Wifi not found

    In reference there is setIP function

  • Good luck.

    That ```setIP()``` function shouldn't be in the docs - it isn't implemented.
    Your module not found message is not unusual. To test loaded, load the above code in the IDE from right hand side. Then in left hand side key:


    You should get a return from that to indicate module was found and loaded and then can proceed to connect and subsequently save your wifi settings for easy connect at boot.

  • As I see, ESP8266 with Espruino onboard cant work in station mode without DHCP on AP enabled? (((

  • You have to wait until the next release, or fetch a travis build or build the firmware by your own.

    There have been added two functions to ESP8266 Wifi: setAPIP() and setIP() with PR #1033 and #1034.

  • If I follow, you mean you can't consistently find it? Well you can jump on your router and reserve the IP address? That's what I do. Next time it boots you'll know its IP which is great for servers and connecting over Telnet.

  • Ah so setIP() is coming. That explains it!

  • Yep and setAPIP() too :)
