Sure, here it is 😊:

// ************************************************************
// *** IMPORTS
// ************************************************************
const wifi = require("Wifi");

wifi.enableMDNS = function (hostname, serviceType, port, callback) {
    let mdns = "AT+MDNS=1," + JSON.stringify(hostname) + "," + JSON.stringify(serviceType) + "," + JSON.stringify(port) + "\r\n";
    this.at.cmd(mdns, 500, function (d) {
        callback(d);
    });
};

// ************************************************************
// *** MAIN
// ************************************************************

/*
 * Called on boot
 */
function onInit() {

    wifi.startAP("EspruinoAP", { password: "0123456789", authMode: "wpa2" }, function (err) {
        if (err) throw err;

        console.log("AP created!");
        wifi.enableMDNS("abcd", "iot", 80, function (result) {
            console.log("enableMDNS result: " + result);
        });

    });

}

That was my guess as well, but replacing this with wifi gives me exactly the same error 🤔.

In the original post:

console.log("Start connection process");
var wifi = require("ESP8266WiFi_0v25").connect(Serial, function(err) {
  if (err)return 1;// throw err;
  Wifi=wifi;

Wifi is set to the result of the connect() function. In your case, wifi is set to the actual library.

Ah, I see 🙂. I used the access point feature only, so never really had to call connect, I updated the example, still getting the same error I'm afraid 🤔.

// ************************************************************
// *** IMPORTS / CONSTANTS
// ************************************************************
const ssid = "<ACCESS_POINT_SSID>";
const password = "<PASSWORD>";

const wifi = require("Wifi");
let Wifi;

wifi.enableMDNS = function (hostname, serviceType, port, callback) {   // <-- Also tried fat-arrow syntax
    let mdns = "AT+MDNS=1," + JSON.stringify(hostname) + "," + JSON.stringify(serviceType) + "," + JSON.stringify(port) + "\r\n";
    Wifi.at.cmd(mdns, 500, function (d) {
        callback(d);
    });
};

// ************************************************************
// *** MAIN
// ************************************************************

/*
 * Called on boot
 */
function onInit() {

    const w = wifi.connect(ssid, { password: password }, function () {
        console.log("Connected");
        Wifi = w;
        
        wifi.enableMDNS("abcd", "iot", 80, function (result) {
            console.log("enableMDNS result: " + result);
        });
    });

}
