ESP8266 - Not connecting to the Losant Platform

Help

Hello, I’ve been trying to to the WORKSHOP 1 – INTERNET BUTTON. The device is able to connect to the internet but when it tries to connect the Losant platform (“Connecting to Losant…”), it just hangs.

This is the code I’ve used:


/**

// Losant credentials.

const char* LOSANT_ACCESS_SECRET = "XXX";

const int BUTTON_PIN = 5;

WiFiClient wifiClient;

LosantDevice device(LOSANT_DEVICE_ID);

void connect() {

  // Connect to Wifi.
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(WIFI_SSID);

  WiFi.mode(WIFI_OFF);
  WiFi.mode(WIFI_STA);
  WiFi.begin(WIFI_SSID, WIFI_PASS);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");

  Serial.println(WiFi.localIP());

  Serial.println();
  Serial.println("Running Workshop 1 Firmware.");

  pinMode(BUTTON_PIN, INPUT);
  connect();

  Serial.println("Button Pressed!");

  // Losant uses a JSON protocol. Construct the simple state object.

    Serial.println("Disconnected from Losant");
    Serial.println(device.mqttClient.state());
    toReconnect = true;
  }

  if(toReconnect) {
    connect();
  }

  device.loop();

Hi @Nick_C,

Since the latest release of that library, we’ve updated the example for the ESP8266:

I would recommend basing your code off of that example as it is updated to the latest and greatest.

Appreciate it. As simple as that.
