• Strange behaviour Date() and setSNTP on esp8266

  in ESP8266 • 3 years, 11 months

  

  Hi MaBe, thank you for your answer.
  That is the tricky part, if i use setSntp, I am getting error :

  Uncaught Error: Cannot read property 'connect' of undefined
  at line 57 col 5
  wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {

  Any idea why is this happening?

  Thanks 😊

• Strange behaviour Date() and setSNTP on esp8266

  in ESP8266 • 3 years, 11 months

  

  I am trying to sync my esp8266 with NTP server, but I am running into a two problems.

  The first one is that if I use setSNTP(sntpServer, timeOffset) method on require("Wifi")

  var wifi = require("Wifi").setSNTP('2.europe.pool.ntp.org',1);
  

  I am getting error msg:

  Uncaught Error: Cannot read property 'connect' of undefined
   at line 57 col 5
  wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
  

  The second problem:
  If I ditch the idea of using SNTP and just use Date(), when esp is connected I print time and it sometimes shows my local time, and sometimes UTC time. But, if I press reset button on the board, it set time to 01.01.1970.

  What am I missing here?

  Here is my code:

      var  on = false;
      digitalWrite(D2,on)
  
      var WIFI_NAME = "name";
      var WIFI_OPTIONS = { password : "passwd" };
      var server = "192.168.1.24"; // the ip of your MQTT broker
      var wifi = require("Wifi").setSNTP('2.europe.pool.ntp.org',1);
      var mqttOptions = { // ALL OPTIONAL - the defaults are below
          client_id : "random",   // the client ID sent to MQTT - it's a good idea to define your own static one   based on `getSerial()`
          keep_alive: 60,         // keep alive time in seconds
          port: 1883,             // port number
          clean_session: true,
          username: undefined,   // default is undefined
          password: undefined,   // default is undefined
          protocol_name: "MQTT",  // or MQIsdp, etc..
          protocol_level: 4,      // protocol level
      };
  
      var mqtt = require("MQTT").create(server, mqttOptions);
  
      //When Mqtt connection is enstablished subscribe on following topics
      mqtt.on('connected', function() {
          mqtt.subscribe("test");
          mqtt.subscribe("led");
          mqtt.subscribe("time");
      });
  
      mqtt.on('publish', function (pub) {
          console.log("topic: "+pub.topic);
          console.log("message: "+pub.message);
          if(pub.topic === "led"){
          console.log('Led msg');
          on = !on;
          digitalWrite(D2,on);
          mqtt.publish('ledStatus',on);
          } else if(pub.topic === 'time') {
          console.log(`I got time`);
          console.log(Date().toString());
          mqtt.publish('time', Date());
          }
      });
  
      wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
      if (err) {
          console.log("Connection error: "+err);
          return;
      }
      wifi.save();
      console.log("Connected!");
      mqtt.connect();
      console.log(`Time : ${Date()}`);
      console.log(`Time Zone : ${Date().getTimezoneOffset()}`);
      });
  

  Thanks :)

  Hi Robin,

  It's been a year and I didn't work on this and I completely forgot how I did it at the time. I wanted to refresh knowledge and got stuck with flashing and pushing the code. Sorry for the inconvenience.

  After a few hours of reading the documentation and examination I managed to make my esp8266 to connect to wifi and mqtt...

  I have a new questions since you answered my previous question.

  1. I do not understand the concept how espruino works. I am used to Arduino loop function and I can't get my head around how it works on espruino? How can I achieve the same behaviour in espruino?
     

  2. I guess that this code snippet listens for message 'connected' from mqtt broker and then executes the subscription to certain topics?

     mqtt.on('connected', function(pub) {//subscribe to topics});
     

  3. Can you please point me how to define pins for digital read and write? I am unable to find the documentation for that?

  Thanks :)

  Hello, I am new here and I am struggling to flash and use espruino with Esp boards.

  Can you please help me and post up to date tutorial so I can know how to push code to the board(permanently) and how to debug board?

  thanks :)

• Espruino on esp32 as greenhouse controller

  in ESP32 • 4 years, 11 months

  

  @Robin, thanks for response. My greenhouse is just near my hose, so I don't need LORA wan for communication. However, I will buy espruino board.

  @allObjects thanks for this elaboration, I will order a few boards and try to build the system.

  Thanks for your help guys :)
