I would like to avoid using local WiFi or BlueTooth because the device will be powered by batteries. I have been looking for examples of such ESP32 to ESP32 local communication but found none. What is the best/fastest way to achieve that? Assistance will be highly welcome. Thanks in Adv...
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 ...

本人想用esp32读取串口数据并且通过MQTT协议传到公共服务器端,但出现了下面的问题: (1)如果将串口设置波特率为115200,则能够立马连上wifi和服务器,但是读取不了串口数据发不上服务器端。 因为所连接开发板传…
The purpose of this paper is to present the possibilities offered by the ESP-NOW communication protocol on the development board ESP32 from Espressif (1). Method: For this paper we used quantitative method. 3 wireless communication modules are used that exchange information from 3 different sensor...
Firstly, we will start by including the necessary libraries that includes the FreeRTOS libraries to generate delays and create tasks, driver/gpio.h as we have to assign signals of a UART peripheral to ESP32 GPIO pins and driver/uart.h for the UART communication. ...
