ESP-NOW is a proprietary wireless communication protocol developed by that enables direct, connectionless data transfer between ESP32 and ESP8266 devices. Unlike traditional Wi-Fi, it bypasses the complex TCP/IP stack to provide ultra-low latency and reduced power consumption, making it ideal for local "downloads" of sensor data or firmware updates.
