Github Copilot - IoT Development



IoT Development often involve low-level hardware interaction, which was always a challenging task for developers. Github Copilot, the cutting edge technology have simplified the task by helping to generate codes for interacting with various sensors, actuators, and communication modules. It have good knowledge about IOT devices like Raspberry Pi, Arduino and GPIO pins. In this section, you can learn how learn to simplify your IoT development with copilot and can go through examples that we generated to understand functioning of github copilot.

Simplify IoT Development With Copilot

GitHub Copilot simplifies IoT development by suggesting code for connecting devices, managing data, and automating processes. It makes it easier to write firmware for IoT devices, set up communication protocols, and integrate with cloud services for data analysis and control. Using copilot can help you adhere to standard coding practices and avoid time spent on reading large documentation for each hardware. We tried to use copilot in every aspects of IoT development and here are some of the use cases which we consider as important.

Hardware Interaction

As we discussed above, GitHub Copilot can suggest code for interfacing with various sensors, actuators, and communication modules, this can be a Arduino, Raspberry pi or any other modern equipments. Checkout the below example we created.

Example: We want to read temperature and humidity data from a DHT11 sensor connected to a Raspberry Pi. We just left a comment describing the setup, and GitHub Copilot generated the code to interface with the sensor.

# DHT11 sensor connected to GPIO pin 4, Read temperature and humidity

import Adafruit_DHT

sensor = Adafruit_DHT.DHT11
pin = 4  # GPIO pin where DHT11 is connected

humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)

if humidity is not None and temperature is not None:
    print(f"Temp={temperature:.1f}C  Humidity={humidity:.1f}%")
else:
    print("Failed to retrieve data from sensor")

You can see that copilot tailored code for the variable value we given in command.

Setup Communication Protocols

We all know that, IoT devices often communicate over protocols like MQTT, HTTP, or WebSockets. Copilot can assist by suggesting implementation code for setting up communication between devices and cloud services.

Example: We want to publish sensor data to an MQTT broker for communication between IoT devices. Copilot helped us by generating the code for setting up MQTT and publishing data. This saved our time spend on reading documentation of MQTT broker.

# MQTT setup for publishing temperature data to broker on IP 192.168.1.100

import paho.mqtt.client as mqtt
import time

broker = "192.168.1.100"
port = 1883
topic = "home/temperature"
client = mqtt.Client()

def on_connect(client, userdata, flags, rc):
    print(f"Connected with result code {rc}")

client.on_connect = on_connect
client.connect(broker, port, 60)

temperature = 25.3  # Example temperature value

while True:
    client.publish(topic, f"Temperature: {temperature}C")
    time.sleep(5)

You can see that Copilot automatically imagined missing values and added example values (in case of temperature) as per industry standards. The script publishes temperature data every 5 seconds to the broker.

Cloud Integration

Most IoT applications are integrated with cloud platforms for device management, data storage, and analysis. GitHub Copilot can help in writing integration code for popular IoT cloud platforms like AWS IoT, Google Cloud IoT, and Azure IoT Hub. Look in to the senario below where we used Wi-Fi and Cloud Integration.

Example: We want our ESP32 to connect to Wi-Fi and send sensor data to an online API. A comment about connecting to Wi-Fi helps the Copilot generate necessary code.

// ESP32 connects to Wi-Fi, sends temperature data to cloud API every 10 seconds

#include <WiFi.h>
#include <HTTPClient.h>

const char* ssid = "TutorialspointNetwork";
const char* password = "SecureP@ssw0rd123";
const char* serverName = "http://api.tutorialspoint.com/data/secure";

void setup() {
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}
// Code Continued....

You can see that ssid and password were automatically filled as copilot remembered those from previous interactions.

Security in IoT

Copilot can assist developers in writing secure protocols (e.g., HTTPS, encryption libraries) and patterns for device authentication, data encryption, and securing communication channels. In the below example,copilot is suggesting code for setting up SSL/TLS.

Example:We wanted a secure communication between our IoT device and a remote server using SSL/TLS. We wrote a comment describing this and Copilot generated the secure connection code.

// ESP32 connects to server with SSL encryption, posts sensor data

#include <WiFiClientSecure.h>

const char* ssid = "TutorialspointNetwork";
const char* password = "SecureP@ssw0rd123";
const char* serverName = "http://api.tutorialspoint.com/data/secure";

WiFiClientSecure client;

void setup() {
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
  
  if (!client.connect(server, 443)) {
    Serial.println("Connection failed!");
    return;
  }
}
//Code Continued....

Limitations of GitHub Copilot in IoT Development

  • Limited Context of Hardware Interfaces: While Copilot can assist with coding, it may not fully understand the intricacies of hardware interfaces and interactions, which are critical in IoT development, requiring developers to have in-depth hardware knowledge.
  • Real-Time Constraints: IoT applications often require real-time performance and low-latency responses. Copilot may not always provide optimal solutions for time-sensitive scenarios, necessitating manual optimization by developers.
  • Security Considerations: Given the security challenges in IoT, Copilot may not consistently suggest secure coding practices or configurations, leaving developers to perform thorough security reviews of the generated code.
