In this video, we learn how to broadcast a message from one ESP32 to multiple ESP32 and then we learn how to send a message from an ESP32 to a particular ESP32.
All of this without a WiFi router or base station. Instead, we will use ESP-NOW.
“ESP-NOW enables a direct and low-power control of smart lights, without the need of a router. This method is power-efficient and convenient.”
