ESP8266 IoT Web server Optimization Using Arduino IDE

Learn to use GZIP compression and improve ESP8266 IoT web server performance.

Created by Farrukh Hussain - Senior Firmware Engineer at Xekera Systems Inc.

Students: 22589, Price: Free

By using GZIP compression, we can reduce bandwidth usage, can increase server speed, and efficiently utilize smaller memories that are issues of prime importance when we are dealing with some embedded platform like ESP8266.

In this course, you will learn all about ESP8266 web server optimization for better performance and optimum utilization of available resources like program and data memories.

I've added some basics like how to add HTML, CSS, JS and graphic contents in ES8266 Arduino sketch, you will find it as simple as ABC even if you are at beginner level. 

If you have already developed some embedded webserver, you will be able to improve its performance by utilizing techniques learned in this course.

Here are key points you will learn

  • How to add web contents like html/css/images etc in Arduino sketch
  • How to do simple minification of server contents
  • How to use Gzip compression on minified contents
  • How to use proper HTTP headers in Arduino sketch for caching static server resources
  • How to use SPIFFS as server contents storage space to allow all program memory space to be utilized by Arduino sketch. 

You will also be able to utilize this compression technique with any embedded platform like Arduino Ethernet/Wifi shields, Mbed, PIC18F97J60 (or any other Microchip Ethernet controller like ENC28j60), STM32F407 (or any other STM32 controller) etc.

To sum up, you will be able use GZIP compression whenever you are coding in C/C++ for any embedded platform, and right now, we are going to test it on Espressif ESP8266 SoC. 

This is going to be real simple but many people have no idea how to do it, and I'm sure anyone can learn it in few minutes.

Please note that this is not a web development course, rather it will teach you best and easiest possible way to handle web contents in Arduino Sketch.

You will get complete webserver code and Arduino sketch that you can modify according to your requirements. Please check introductory lecture that shows how this webserver works. 

Which ESP8266 board you need for testing as there are many available?

You may use any ESP board that have multiple IO pins, not necessarily Nodemcu.

Happy learning.

Here is a brief overview of Ethernet from Wikipedia:

Ethernet is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates and longer link distances. Over time, Ethernet has largely replaced competing wired LAN technologies such as token ring, FDDI and ARCNET.

The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with hubs or switches. Over the course of its history, Ethernet data transfer rates have been increased from the original 2.94 megabits per second (Mbit/s) to the latest 100 gigabits per second (Gbit/s). The Ethernet standards comprise several wiring and signaling variants of the OSI physical layer in use with Ethernet.

Systems communicating over Ethernet divide a stream of data into shorter pieces called frames. Each frame contains source and destination addresses, and error-checking data so that damaged frames can be detected and discarded; most often, higher-layer protocols trigger retransmission of lost frames. As per the OSI model, Ethernet provides services up to and including the data link layer.

Since its commercial release, Ethernet has retained a good degree of backward compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. The primary alternative for some uses of contemporary LANs is Wi-Fi, a wireless protocol standardized as IEEE 802.11.

Developing and Hosting a Short Lived Website for a Free

Installing SSL certificate for Spring Boot web application

Students: 968, Price: Free

Nowadays so many tools and technologies are available which can be used for free for a limited amount of time. Sometimes it becomes a requirement to create a short-lived secure web application for constrained budget events or something else. So this is the right course that has the above-mentioned requirement. In this course, learning will learn how to clone the spring boot project into the Eclipse IDE. The project is already available on the Git repository. The spring boot application will be deployed to the AWS EC2 instance to make it publicly available. You require to have your own AWS credentials. Traffic capture can be done using a utility like Wireshark; hence the publicly available web application needs secure communication, hence self-signed certificate creation is taught. To create a self-signed certificate ketol utility of JDK is used. The deployed application is accessible through an IP address which is no the proper way to make the application public. Freenom is used to get free domain registration. The self-signed certificate is not authorized hence free SSL certificate will be created on ZeroSSL. OpenSSL is used to convert the certificate generated by ZeroSSL into the PKCS format. The certificate generated from ZeroSSL is authorized and can work with the spring boot application.
