In this tutorial, we will learn how to use Bluetooth Low Energy (BLE) on the ESP32 microcontroller using the Arduino IDE. We will establish communication between the ESP32 as a BLE server and an Android BLE application, enabling the transmission and reception of data between the two devices. First, we will configure ESP32 in both … Read more
In this tutorial, we will explore how to use the Bluetooth Classic on ESP32 with Arduino IDE. For demonstration, we will establish bidirectional data communication between the ESP32 and an Android cell phone over Bluetooth Classic. Firstly, we will see a simple example to send data from ESP32 to an Android app. After that, we … Read more
In this tutorial, we will learn about HC-05 Bluetooth to serial port module and how to interface it with ESP8266 NodeMCU. This Bluetooth device operates on UART communication. In other words, it uses serial communication to transmit and receive data serially over standard Bluetooth radio frequency. Therefore, we will use TX, RX pins of ESP8266 … Read more
