Arduino

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Connect Arduino-based boards with the Qubitro MQTT package.

Nano 33 IoT

The Arduino Nano 33 IoT is Arduino's smallest board to get started with Internet of Things (IoT). Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the powerful u-blox NINA-W102 Wi-Fi module and the ECC608A crypto-chip for security.

MKR WiFi 1010

The MKR WiFi 1010 is a great choice for any beginner, maker or professional to get started with Internet of Things (IoT).Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the and the ECC508 crypto-chip for security.

Nano 33 IoT

Getting Started

Before getting started, make sure that required libraries are installed by visiting the setup page

Libraries

Include the required libraries and define objects on top of the page.

#include <QubitroMqttClient.h>
#include <WiFiNINA.h> 

WiFiClient wifiClient;
QubitroMqttClient mqttClient(wifiClient);

Variables

Define the required variables.

char deviceID[] = "PASTE_DEVICE_ID_HERE";
char deviceToken[] = "PASTE_DEVICE_TOKEN_HERE";
char host[] = "_IP_";
int port = 1883;

Data Structure

Qubitro currently has support for key-value paired JSON objects as a data type. Nested values are not supported yet.

{
  "Key1" : "Value1",
  "Key2" : true,
  "Key3" : 90
  ...
}

An example : "{\"Temp\":33}"

Setup method

Set client id for identification
Set device id and token for authentication
Connect to the Qubitro broker
Subscribe to the topic
Set onMessage method to listen subscribed topic

void setup() 
{
  
  mqttClient.setId(deviceID);
   
  mqttClient.setDeviceIdToken(deviceID, deviceToken);

  Serial.println("Connecting to Qubitro...");

  if (!mqttClient.connect(host, port)) 
  {
    Serial.println("Connection failed! Error code = ");
    Serial.println(mqttClient.connectError());
    Serial.println("Visit docs.qubitro.com or create a new issue on github.com/qubitro");
    while (1);
  }
  
  Serial.println("Connected to the Qubitro !");

  mqttClient.subscribe(deviceID);

  mqttClient.onMessage(receivedMessage);    
                                      
}

loop method

Publish data to the subscribed topic

void loop() 
{
   mqttClient.poll();   
   mqttClient.beginMessage(deviceID);   
   mqttClient.print("{\"Temp\":33}");
   mqttClient.endMessage();                
   delay(2000);   //wait 2 seconds
}

receivedMessage method

Print whenever message received

void receivedMessage(int messageSize) 
{
  Serial.print("New message received:");
  while (mqttClient.available()) 
  {
    Serial.print((char)mqttClient.read());
  }
  Serial.println();
}

Example

The following example :

Connects to the broker
Subscribes to the topic (the device itself in this example)
Publishes data in a loop with a delay of 2 seconds.
Prints message and subscribed topic (the device itself in this example)

Example output:

Connecting to WiFi...
Connected to the WiFi
Connecting to Qubitro...
Connected to the Qubitro !
New message received:{"Temp":33}
New message received:{"Temp":33}
New message received:{"Temp":33}
