In this guide, we’ll show you how to establish a two-way communication between two ESP32 boards using ESP-NOW communication protocol. As an example, two ESP32 boards will exchange sensor readings (with a range in open field up to 220 meters ~ 722 feet). Watch the Video Introduction ...
I am building weather station and I am stuck on communication between two ESP32 over esp-now and at the same time connect to the internet for download forecast and information about time and date. Can you help me please? Is it possible? Thanks for every help Peter Re: Weather station -...
we want to try connect ESP32 with STM32 via UART using the ESP_AT after flashing the esp32-wroom-32e with esp-at firmware (ESP32-WROOM-32-V2.2.0.0), the output from UART0(USB in dev-ket) is as expected (figure1). figure1.png But we couldn't communicate with the ESP32 via ...
In this tutorial, we will learn about SPI communication and how to perform master slave communication between two ESP32 development boards using ESP-IDF. We will use SPI Slave and SPI Master drivers to demonstrate SPI master (Host) and SPI slave (Device) communication between each other. Before...
The objective of this post is to explain how to use FreeRTOS queues to communicate between two different tasks. The tests were performed using a DFRobot’sESP-WROOM-32device integrated in aESP32 FireBeetle board. Introduction The objective of this post is to explain how to use FreeRTOS queue...
Install ESP32 ESP-IDF on Linux Ubuntu UART Introduction UART communication also known as Universal Asynchronous Receive Transmit or Serial communication is one of the simplest and commonly used communication protocols used between two devices. Data transfer between the two devices is via transmission and...

I am working on serial communication between esp32 and lpc1768 microcontroller. I have established the communication successfully with a ESP32-WROOM-32U module and our custom board with LPC1768 chip. But, however when I solder the ESP32-WROOM-32U chip on our custom board the communication fai...
is known as Universal Asynchronous Receiver/Transmitter (UART) Communication is used. For most sensors and systems, the main communication method is considered to be UART. In order to share workload, information and perform different tasks, sometimes communication between two ESP32 boards is required...
