Last time, one ESP-NOW signal reached every board listening — that's broadcast. This time, I show you how to talk to exactly one board and not the others, using unicast addressing and the sender's MAC riding along with every packet. Three boards, two buttons and two LEDs each. Every board can independently address either of the other two — press one button, only the intended board reacts, the other stays dark. 00:00 – Watch: ESP32 communicates 00:10– ESP-NOW broadcast 00:25 – Broadcast cannot do that 00:35 – Why we need Uni-cast 00:46 – ESP-NOW Uni-cast 01:06 -- Connection details 01:30 -- Where the code is (GitHub, not a walkthrough) 01:55 – Live demo — I choose exactly who reacts 02:20 – ESP-NOW's real limit isn't the protocol, it's the workflow Full code — sender and all three mesh node sketches: github.com/ProtoCraft-Electronics/ProtoCraft-Electronics ESP32 Broadcast Video:    • One Switch Controls Two ESP32 Boards Insta...      / @protocraftelectronics   #ESP32 #ESPNOW #Arduino #IoT #EmbeddedSystems
