Gentlemen,

i've a problem:

Flash map 4MB:512/512, manuf 0x20 chip 0x4016

I try to connect to an ap via:

var wifi = require("Wifi");
wifi.connect("Bratatatat-666", {password: "SomeThiNGLIKeTh8t"},
   function(err){
  if(err)console.log(err);
  else console.log("connected!");
});

and i get "bad password" or stock in "connecting" but i can swear the password is absolutely correct. 100%!11!!1!

My router is available on 2.4 and 5 GHz and with another MC, wich is not flashed with Espruino, there is no problem to connect.

Please help!

If i connect to an mobile-hotspot, wich has password like "espruino1337", the connection is successfull.

Add channel and bssid to make it easier to connect to the 2.4 GHz access point and try again.

Doesn't make any difference, sorry.

var wifi = require("Wifi");
wifi.connect("Vodafone-8751", {
  password: "ABCDEfGh1jKLmnoP", //Password is like this
  channel: 1,
  bssid: "2C:58:4F:92:A7:21"}, 
  function(err){
    if (err) console.log(err);
    else console.log("connected!");
});

Is there any chance, that espruino converts the pw-string not correctly? How i said, it works without any problems at a esp32 with regular firmware. It is really strange because even with the espruino i was able to connect to the hotspot of my mobile-phone. Security-standard of my wlan-router is WPA2-Personal, whatever "Personal" meens ..

Hmm, try this to get some info about the access points in your surrounding:

require("Wifi").scan((arrayOfAcessPoints) =>{print(arrayOfAcessPoints);});

What router model are you using?

Can you change Personal to PSK (pre-shared key)? Or is there only an option to switch between Personal and Enterprise?

require("Wifi").scan((arrayOfAcessPoints) =>{print(arrayOfAcessPoints);});

Output:

[
  { "rssi": -60, "channel": 1,
    "authMode": "wpa2",
    "isHidden": false,
    "ssid": "Vodafone-8751",
    "mac": "2c:58:4f:92:a7:21"
   },
  { "rssi": -66, "channel": 11,
    "authMode": "wpa2",
    "isHidden": false,
    "ssid": "Vodafone-3E7C",
    "mac": "88:71:b1:a7:21:d3"
   }
 ]

Router is a DOCSIS 3.1 and there are just the options "off", "wpa2" and "wpa and wpa2"

That mistake I had several years ago
It turned out that one of my routers was teasing.
I use the showed up start and since then there have been no problems.
The other routers have no problems.

  function lan() {
    wlan.connect(logon.ssid, {password: logon.pass}, function (s) {
      boola = true;
      if(s==='bad password') {
        if(debug>0) {console.log('restart lan');}
        lan();
      }
    });

    if(debug)console.log("Frida is my watchdog");
    if(debug)console.log(wlan.getIP().ip);
  } // end lan()

  setTimeout(lan,400);

  
  wlan.on('connected', function(s) {
    if(debug)console.log('Starter test', wlan.getIP().ip);
    if(boola) {
      boola = false;
      startTimeServer();
      //httpSrv.listen(80);
    }
  });

"wpa2" should work
"wpa and wpa2" could cause problems
WiFi 6 could cause problems

Things like "debug", "logon" are not defined ...

May it depends on long password, how do you think? I've never tested Espruino with so long passwords. Some old devices I had require password to be not more then 16 or even 8 symbols, I forget.

// lan-test00 - esp8266_01

var ver = 'ver = V1.0';

function onInit(a) {
  debug = (typeof a==='undefined')?0:a;
  var wlan     = require("Wifi");
  var http     = require("http");
  var logon    = require('LOGON');


  wlan.stopAP();
  wlan.disconnect();


  var boola;
  function lan() {
    //wlan.connect(yourssid, {password: yourpassword}, function (s) {
    wlan.connect(logon.ssid, {password: logon.pass}, function (s) {
      boola = true;
      if(s==='bad password') {
        if(debug)console.log('restart lan');
        lan();
      }
    });

    if(debug)console.log("Frida is my watchdog");
    if(debug)console.log(wlan.getIP().ip);
  } // end lan()
  setTimeout(lan,400);


  wlan.on('connected', function(s) {
    if(debug)console.log('Starter test', wlan.getIP().ip);
    if(boola) {
      boola = false;
      //do what you need to do.
      if(debug)console.log('tilsluttet lan');
    }
  });

} // end onInit()

onInit(2); // comment or remove before save

You should not use logon and use your own logon values instead. That's because I have my logon values in a module.
I use debug until the program runs properly.

So, here is what i come up with:

var wifi = require("Wifi");
var doit;

var ssid = 'Vodafone-8751';
var passwort = 'ABCDEfGh1jKLmnoP';

wifi.stopAP();
wifi.disconnect();

function lan() {
  wifi.connect(ssid, {password: passwort}, function(s) {
    if (s === 'bad_password') {
      doit = true;
      console.log('Es ist ein Fehler aufgetreten: ' + s);
      console.log('Verbindungsversuch gestartet ...');
      lan();
    }
    if (s != 'bad_password') {
      console.log('Es ist ein Fehler aufgetreten: ' + s);
      console.log('Verbindungsversuch wird abgebrochen.');
    }
  });
  console.log(wifi.getIP().ip);
} // Ende: lan()
setTimeout(lan,500);

wifi.on('connected', function(s) {
  console.log('Es hat endlich geklappt, Verbindungsstatus: ' + s);
  if (doit) {
    doit = false;
  }
});

and get stock in:

0.0.0.0
Es ist ein Fehler aufgetreten: bad_password
Verbindungsversuch gestartet ...
0.0.0.0
Es ist ein Fehler aufgetreten: bad_password
Verbindungsversuch gestartet ...
0.0.0.0
Es ist ein Fehler aufgetreten: bad_password
Verbindungsversuch gestartet ...
0.0.0.0
