WifiEspNow
Arduino library for ESP-NOW, a connectionless WiFi communication protocol on ESP8266 and ESP32.
What is WifiEspNow?
WifiEspNow is an Arduino library that implements ESP-NOW, a connectionless WiFi communication protocol for ESP8266 and ESP32 microcontrollers. It provides a simple wrapper around ESP-IDF functions to enable direct device-to-device communication without a WiFi network. The library supports unicast on both platforms and multicast on ESP32, along with a custom pseudo-broadcast protocol.
IoT developers and hobbyists working with ESP8266 or ESP32 who need efficient, low-overhead wireless communication between devices without traditional network infrastructure.
It offers a straightforward Arduino-compatible interface to ESP-NOW, reducing the complexity of using ESP-IDF directly while enabling fast, connectionless communication ideal for sensor networks, remote controls, and other IoT applications.
