ESP-NOW - Peer to Peer ESP32 Network

Set up a private peer-to-peer network without WiFi using ESP-NOW! I’ll show you how to use this powerful protocol with several ESP32 boards.

Use two boards, or use ten. Transmit in one direction (half-duplex) or bidirectionally (full-duplex). With or without encryption. This magic all comes courtesy of the 2.4GHz radio transceiver that powers the ESP board's WiFi and Bluetooth features. We can also use this radio to set up a network to send small (250 bytes) packets of data between ESP boards. No WiFi or Router is required. Mix and match boards as much as you want. I’ll be showing you how ESP-NOW works, and we’ll perform a few simple experiments with a bunch of ESP32 boards. We’ll end by building a remote temperature sensor system, then expanding it to use multiple sensors.
