mDNS is working with Bonjour

Oh, that makes perfect sense, thanks 🙂! Unfortunately it means that I can't easily take the wifi-module source code and add the extra functionaly in there directly--so I have to stick with the current approach.

Great suggestion with using dump 👍. It does seem a little strange. It's as if some stuff (eg. the onInit) is defined twice. I guess the pinMode is stuff generated by default. This is what I get:

var ssid = "EDITED OUT";
var password = "EDITED OUT";
var Wifi = undefined;
function onInit() {
  const w = wifi.connect(ssid, { password: password }, () => {
        console.log("Connected");
        Wifi = w;
 
        wifi.enableMDNS("abcd", "iot", 80, function (result) {
            console.log("enableMDNS result: " + result);
        });
    });
}
pinMode(D0, "input_pullup", true);
pinMode(D12, "input_pullup", true);
pinMode(D13, "input_pullup", true);
pinMode(D14, "input_pullup", true);
pinMode(D15, "input_pullup", true);
pinMode(D18, "input_pullup", true);
pinMode(D19, "input_pullup", true);
pinMode(D21, "input_pullup", true);
pinMode(D22, "input_pullup", true);
pinMode(D25, "input_pullup", true);
pinMode(D26, "input_pullup", true);
pinMode(D27, "input_pullup", true);
pinMode(D34, "input_pullup", true);
pinMode(D35, "input_pullup", true);
pinMode(D36, "input_pullup", true);
pinMode(D37, "input_pullup", true);
pinMode(D38, "input_pullup", true);
pinMode(D39, "input_pullup", true);
