  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,

• [SOLVED] Connect to MQTT problems

  in ESP8266 • 6 years, 7 months

  

  Hi,

  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 192.168.10.44 on port 1883.
  1526108440: New client connected from 192.168.10.44 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("192.168.10.43", {
    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);
      mqtt.connect();
    } else {
      console.log('error: ',err);
    }
  });
  wifi.stopAP();
  
  mqtt.on("connected", function(){
    console.log("connected");
  });
  
  mqtt.on("disconnected", function(){
    console.log("disconnected");
  });
  

  The output is always the same:

  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: "192.168.10.43",
     });
     

  6. Run mosquitto server in verbose mode "mosquitto -v":

     1526109123: New connection from 192.168.10.44 on port 1883.
     1526109123: New client connected from 192.168.10.44 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
