     In this blog post we will be diving into the world of esp32's Bluetooth capabilities. The esp32 is famous for its Wi-Fi capabilities but it also has some Bluetooth functionalities like the Bluetooth classic and the BLE that is Bluetooth Low Energy.  In this post we'll be mainly looking at the Bluetooth classic. ps: Micropython doesn't support bluetooth classic of the esp32(at the time of writing).    let's get started STEP 1:  Connect the Esp32 to your computer and open the Arduino IDE.     First of all for understanding this we are going to look at the examples. we need the serial to serial BT.      if you have already used Bluetooth with Arduino you will understand it easily, it's similar you can go check out my video.     Code Explanation  In the first line we include the Bluetooth serial library   #include "BluetoothSerial.h" next if you want to use a pin or password we can set that PIN to acc...

 In this blog post, we will dive into the world of ESP32 development using the popular Arduino IDE . Whether you're a beginner or an experienced developer, this step-by-step guide will help you set up your ESP32 board, configure the Arduino IDE. I've been using the esp32 board with Micropython, but now  I'm changing it to the Arduino is becaus e I found that the esp32's Bluetooth classic Bluetooth cannot be used with Micropython (it has some binding issues) The esp32 is a powerful microcontroller that's perfect for building IOT devices and if you are new to the esp32 one of the first things that you will need to start with is an Arduino IDE, I'll walk you through the process step by step   If you would like to watch a video tutorial of it, here you go   STEP:1  First we will need to install the esp32 board definitions in the Arduino IDE.   for that we will go to the preferences menu and entering a URL -  https://raw.g ithubusercontent.com/espressif...
