How To Read Bin File From ESP32 and ESP8266

Video Description

In this video, I'll show you how to extract hex code from an ESP32 or ESP8266. We'll use the ESP32 development module for this demonstration, but the steps are the same for other devices. After uploading a blink sketch to the ESP32, we'll extract the code and upload it to another module. This process allows easy cloning of functionality across multiple devices, saving you time and effort in programming. Let's get started! -------------------------------------------------------------------------------------------------------------------- Commands Used in This Project -------------------------------------------------------------------------------------------------------------------- 1.
