So- things that might be wrong: Power: Ensure you have adequate power - usually an FTDI is not good enough - this can be the difference between utter reliability - and power up. You need network access to the documents folder of the web server. This is a web-based Thingspeak weather app. This can be achieved with help of SPIFFS (SPI Flash File System) or use of dataURL for small size images. system control communication using Arduino and ESP8266 hardware. Perhaps what I eventually settled on can be considered the 'poor man's way' for implementing dynamic web forms on the esp8266. The code was tested on both the ESP32 and the ESP8266. The motive of the project is to create a web server on the module that can host multiple clients over the network. The ESP8266's flash memory isn't huge, and most text files, like html, css etc. ESP8266 Webserver: send or download huge files. Open your browser and enter the IP Address 192. I'm working on a webserver on ESP32 in Arduino IDE and would like to load an html-file. 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. With this knowledge you can then build Internet Of Things (IOT) projects that can be configured by web form. Directly from code.
