Two components define how data is formatted and used within the BLUEDROID stack: Bluetooth Profiles –These determine the overall function of each protocol layer. Bluetooth Protocols –These define the message formats and procedures. The BLUEDROID stack in the ESP32 supports the following Profiles and...
In the device's firmware, there is a set of established communication protocols that specify the format of the model results output, and what the user can do with the models. Due to space issues, we won't be expanding on the specifics of these protocols in this wiki, we'll be ...
The test circuit for the ESP32 based WebSocket client is shown above. As you can see, on the left-hand side, we have ourESP32 based serverthat has a DHT22 sensor and a LED attached, and on the right-hand side, we have our Android phone which is acting as a WebSocket client...
**Advanced Connectivity and Flexibility** The ESP32-Audio-Kit is not just about audio; it's about connectivity. It supports a variety of communication protocols, including UART/SPI/I2C/I2S/PWM/ADC/DAC, and is compatible with a range of peripherals. The board's flexibility is further enhanced...

The introduction of industry IoT (IIoT) and Artificial Intelligence of Things (AIoT) creates new challenges in terms of communication. The presented comparation shows the advantages and disadvantages of two communication protocols, which are suitable for new coming generation of IoT devices. Message ...
Normally, ESP32-WROVER-KIT adds two serial ports such as /dev/ttyUSB0 and /dev/ttyUSB1. We want the second serial port, which is used for serial communication with ESP32.wget https://github.com/Matheus-Garbelini/braktooth_esp32_bluetooth_classic_attacks/releases/download/v1.2.0/esp32...
I2S and ESP32 The ESP32 has two I2S peripherals,I2S0,andI2S1. Each one can be configured as a Controller or Target, and each one can be an audio Transmitter or Receiver. Each I2S controller can operate in half-duplex communication mode. Thus, the two controllers can be combined to estab...
