Differences in getIP() syntax

On an ESP8266 running v1.85

var wifi = require("Wifi");
wifi.connect(Netname, {password:Key}, function(err){
  console.log("connected? err=", err, "info=", wifi.getIP());
});

On an Espruino v1.85 board connected to an AT command ESP8266

var wifi = require("ESP8266WiFi_0v25").connect(serial, function(err) {
  if (err) throw err;

  wifi.reset(function(err) {
    if (err) throw err;
    console.log("Connecting to WiFi");
    wifi.connect(SSID,key, function(err) {
      if (err) throw err;
      wifi.getIP(function(l,ip){console.log("IP= ",ip,"\n\r"+l);});
