In this tutorial, we will take an example of point-to-point communication between two ESP32 boards. Important Terms in BLE Here are some important terms which one should know while working with ESP32 BLE applications: GATT: GATT or Generic attributes which defines a hierarchical structure for d...
Introduction to ESP32 Bluetooth Serial Communication Using Arduino IDE Serial communication is important when it comes to microcontrollers as it allows devices to exchange data between them. ESP32 comes with UART and multiple other communication protocols that allows it to exchange data with a PC and...
Discover everything you need to master Bluetooth (Classic and Low Energy) with the ESP32 in no time. ESP32 boards are great for IoT projects because they support Wi-Fi, Bluetooth Classic, and Bluetooth Low Energy.
To test the code, simply compile it and upload it to your ESP32 using the Arduino IDE. Once it finishes, go to your computer’s Bluetooth devices and start a scan. The ESP32 should get detected, as shown in figure 1. Figure 1 – ESP32 detected as Bluetooth device on Windows 8 (men...

Bluetooth Classic on ESP32 with ESP-IDF, establish bidirectional communication between ESP32 and an Android phone over Bluetooth Classic
The ESP-WROOM-32 integrates traditional Bluetooth, Bluetooth Low Energy and Wi-Fi for a wide range of uses: Wi-Fi supports a wide range of communication connections, as well as direct connection to the Internet via a router; Bluetooth allows users to connect their phones Or broadcast BLE ...
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. ...
ESP32-WROOM-DA is pin-to-pin compatible withESP32-WROOM-32E, thus facilitating quick and easy migration between these two modules. The unique antenna design of ESP32-WROOM-DA has resulted in the module's excellent wireless communication, even under difficult circumstances. Thus, makers using ES...
In the setup(), 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 Device BLEDevice::init("MyESP32");...
