Learn how to use ESP-NOW, a connectionless communication protocol by Espressif, to exchange data between ESP32 boards programmed with Arduino IDE. See examples of one-way and two-way communication, how to get board MAC address, and how to send and receive structures.
ESP-NOW is a low-power and quick protocol for smart devices, without router. It works with Wi-Fi and Bluetooth LE, and supports ESP8266, ESP32, ESP32-S and ESP32-C series of SoCs.
ESP-NOW . Overview . ESP-NOW is a kind of connectionless Wi-Fi communication protocol that is defined by Espressif. In ESP-NOW, application data is encapsulated in a vendor-specific action frame and then transmitted from one Wi-Fi device to another without connection.
Learn how to use ESP-NOW, a low-latency and efficient protocol developed by Espressif, to send data between ESP8266 or ESP32 boards. Find out the hardware requirements, communication modes, limitations, and security considerations of ESP-NOW.
ESP-NOW is a component for ESP32 that supports one-to-many and many-to-many device connection and control for mass data transmission. Learn how to add ESP-NOW to your project, see examples, and read the user guide and security policy.
ESP-NOW is a communication protocol designed for low-power, low-latency, and high-throughput communication between ESP32 devices without the need for an access point (AP). It is ideal for scenarios where devices need to communicate directly with each other in a local network. ESP-NOW can be used for smart lights, remote control devices, sensors ...
Learn how to use ESP32 ESP-NOW, a wireless communication protocol for ESP32 devices, to perform one-way or two-way data transmission. Follow the steps to set up Arduino IDE, obtain ESP32 MAC address, and write Arduino sketches for ESP-NOW.
Learn how to use ESP-NOW, a connectionless Wi-Fi protocol for low-power and low-latency peer-to-peer communication, with Arduino. See examples of basic setup, two-device communication, broadcasting, and network of devices.
ESP-NOW is a Wi-Fi-based protocol that allows device-to-device communication without a router or TCP/IP stack. Learn about its advantages, application scenarios, data rate, power consumption, and more.
ESP-NOW is a protocol that reduces the OSI model to one layer and allows direct data transmission between paired devices. It has advantages such as quick response, low-power consumption, good compatibility, improved range, and multiple control methods.
