#223 ESP-NOW simple demo - easy IOT data transfer on ESP32 or ESP8266
In this IOT world we need a simple way of sending data to a hub. Welcome to ESP-NOW.
JLCPCB Only $2 for PCB Prototype any colour including aluminium.
It was brought to my attention by a viewer that ESP-NOW is a protocol ideally suited to sending out small amounts of data (up to 250 characters) so I just had to experiment.
With an ESP32 receiver and an ESP8266 transmitter I modified the sketches written by @Rui Santos and which worked well. It was obvious that I could use this approach in my unified workshop “smart“ heater controller.
Watch the video for further ideas and a working example (that you can get working in about 15 minutes)!
