ESP Web OTA

Abstract

1. Introduction

Easily add web based OTA updates to your ESP32/ESP8266 projects.

2. Objective

Simple web based Over-the-Air (OTA) updates for ESP based projects

This project demonstrates how C++, ESP32, ESP8266 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/scottchiefbaker/ESP-WebOTA.git
cd ESP-WebOTA

#include <WebOTA.h>

void setup() {
    // Other init code here (WiFi, etc)

    // To use a specific port and path uncomment this line
    // Defaults are 8080 and "/webota"
    // webota.init(8888, "/update");

    // If you call useAuth() in your setup function WebOTA will use
    // HTTP digest authentication to request credentials from the user
    // before allowing uploads
    // webota.useAuth("username", "password");
}

void loop() {
    // Other loop code here

    webota.handle();
}

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
