Esp32 arduino bluetooth11/13/2023 ![]() PinMode(2, OUTPUT) //set GPIO 2 as output SerialBT.begin("ESP32 LED") //set the name of the Bluetooth module The BluetoothSerial object is then created to handle Bluetooth communication. This code includes the BluetoothSerial library, which provides support for Bluetooth Classic communication on the ESP32. Open the Arduino IDE, select the appropriate board and port, and create a new sketch.Īrduino Code for ESP32 Bluetooth Classic Interfacing with LED.Connect the ESP32 to your computer using a USB cable.Here’s an in-depth tutorial that you can follow for this - Getting Started with ESP32 using Arduino IDE - Blink LED The Arduino IDE provides a user-friendly interface for beginners and advanced users alike, allowing you to write and upload code to the ESP32 without requiring advanced knowledge of programming languages. Connect one end of the resistor to the short leg of the LED and the other end to the ground (GND) pin on the ESP32.Connect the short leg of the LED (negative) to the breadboard.For example, you can connect it to GPIO 12. Connect the long leg of the LED (positive) to one of the GPIO pins of the ESP32.This allows devices to communicate with each other over Bluetooth, while still being able to connect to the internet and other network resources via Wi-Fi.įirst, let’s check out the materials which we will require: -Ĭircuit Diagram - ESP32 Bluetooth classic with LED Bridging Bluetooth and Wi-Fi: The ESP32's internal Bluetooth Classic module can be used in conjunction with its Wi-Fi capabilities to create a bridge between Bluetooth and Wi-Fi networks.Once a connection is established, the ESP32 can send and receive data to and from the other device. ![]()
