    Thank you very much @Gordon. I delete flash and upgrade to 1v97.98 and works great!!!

    I saw new versions at http://www.espruino.com/binaries/travis/­master/ for example release 1v97.100. This versions are the last development versions?. Are the same as github repository "master" branch?

    Thank you.

    Best regards,

    I'm trying to use MQTT on a ESP8266 (Flash map 1MB:512/512, manuf 0xc8 chip 0x4014) and always returns same error:

    1526108440: New connection from on port 1883.
    1526108440: New client connected from as 4e8422275dd0 (c1, k60).
    1526108440: Socket error on client 4e8422275dd0, disconnecting.

    It's only a simple connection test code like this:

    var wifi = require("Wifi");
    var mqtt = require("MQTT").create("", {
      keep_alive: 60,
      clean_session: true
    wifi.connect("MyWifi", {password: "MyPassword"},function(err){
      if (!err) {
        const info = wifi.getIP();
        console.log('connected? err=', err, 'info=', info);
      } else {
        console.log('error: ',err);
    mqtt.on("connected", function(){
    mqtt.on("disconnected", function(){

    The output is always the same:

    Espruino is Open Source. Our work is supported
    only by sales of official boards and donations:
    Flash map 1MB:512/512, manuf 0xc8 chip 0x4014
    >connected? err= null info= {
      "ip": "",
      "netmask": "",
      "gw": "",
      "mac": "5c:cf:7f:f1:bd:25"

    I try a lot of configurations and I don't know how to continue:

    1. Mosquitto server's: 1.4.14, 1.4.15, "test.mosquitto.org",...etc
    2. Test on different ESP8266 boards.
    3. Using module "MQTT" and "TinyMQTT".
    4. Move "mqtt.connect()" line inside "wifi.connect" callback
    5. Try using connect directly:
      var mqtt = require("MQTT").connect({ host: "", });
    6. Run mosquitto server in verbose mode "mosquitto -v":
      1526109123: New connection from on port 1883. 1526109123: New client connected from as 3fefc4344328 (c1, k60). 1526109123: Sending CONNACK to 3fefc4344328 (0, 0) 1526109123: Socket error on client 3fefc4344328, disconnecting.

    Mosquitto server is up and runnig with anonymous access acepted. I'm using this server with other esp8266 boards running native C code and goes good, so I think that is no problem with the server.

    If someone can help me with this problem, I would be enormously grateful.

    Thank you
