Strange issue with wifi!11!!1!

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 ..
