Another big difference between the two versions of Bluetooth is the way used to transfer data. Bluetooth Classic uses something similar to Serial Communication, while Bluetooth Low Energy uses a client-server model, where it employs the GATT (Generic Attribute Profile) to structure data. You can ...
There are different ways to perform this experiment. As said earlier, the ESP32 can act either as a server or as a client. In this experiment, we will use the app to carry on the communication. This is an easier method and usually, students prefer to control the Bluetooth through a pro...
In this tutorial, we will learn how to use Bluetooth Classic on ESP32 with ESP-IDF. We’ll establish bidirectional data communication between the ESP32 and an Android phone over Bluetooth Classic. We will see an example of controlling the onboard LED of the ESP32 by sending ON and OFF co...

In thesetup(), it starts the serial communication at a baud rate of 115200. Serial.begin(115200); Then, you create a BLE device called “MyESP32”. You can change this name to whatever you like. // Create the BLE DeviceBLEDevice::init("MyESP32"); ...

I was looking for sample code to create a simple application for serial communication between the ESP32 and a mobile phone. It took a long time before I figured out how things work. Here is some information - for a start without code. ...
