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 ESPNOW. JLCPCB Only 2 for PCB Prototype any colour including aluminium. It was brought to my attention by a viewer that ESPNOW 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) Modified sketches (Arduino IDE) for the sender and receiver in my GitHub Click on ANY of the Banggood links below before visiting them to support this YouTube channel ESP8266 modules ESP01 simple unit ideal as a sender 4 Geekcreit Wireless NodeMcu Lua C
