Hi There
I just received a few espruino.wifi boards. Nice work!

I try to detect the connected or disconnected event without success. I did not get any of this two events. No connected event on connect and no disconnect event when i switch off my wifi AP.

Code:

var wifi = require("EspruinoWiFi");
var WIFI_NAME = "XYZ";
var WIFI_OPTIONS = { password : "PW" };

console.log('Starting...');

wifi.on('connected', function(data) {
    console.log("> connected "+data);
});
wifi.on('disconnected', function(data) {
    console.log("> disconnected "+data);
});

wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
    if (err) {
        console.log("Connection error: "+err);

        return;
    }
    wifi.getIP(function(f,ip) {
        console.log("Connected: ", ip);
    });
});

The console output is:

I'm afraid there aren't any events at the moment - where did you find out about them from? You could try this and see if it gives you what you need:

wifi.at.registerLine("WIFI CONNECTED", function() { wifi.emit("connected"); }); 
wifi.at.registerLine("WIFI DISCONNECT", function() { wifi.emit("disconnected"); }); 

I'm afraid I don't have time to test at the moment, but if it doesn't break anything else I can add it to the module. You might need to use "WIFI GOT IP" instead of "WIFI CONNECTED" though - since I guess you care more about whether you have an IP address than if you're connected.

Many thanks Gorden.
I was confused regarding the Wifi documentation here:

I know - it is a bit confusing. Ideally that'd be changed - at some point I'll try and bring everything in line a bit more.

That Wifi library is ESP8266-only at the moment. I'm trying to get it and the EspruinoWiFi library in sync in the hope that at some point I will properly merge the two. Unfortunately we're not quite there yet.
