I am trying to connect 2 MCU with ESP-NOW. The code works fine on the way ESP8266->ESP32, but on the way ESP32->ESP8266. Sometimes a messsage arrives, but most of time the message is lost. I tried also with different roles, and only sending, but I failed. Also with broadcast ...
Our first test is very simple and is a great way to learn the fundamentals of sending and receiving data using ESP-NOW. We will need two ESP32 boards for this test. One board will be the Initiator (sender), and the other will be our Responder (receiver). We don’t require any addit...
