Hello again,

I tried to connect two ESP8266 with the same code, ans works fine. Works with specific MAC and broadcast MAC without problem.

I think that maybe we have a compatibility problem.

Some idea?

Thanks,
Juan Carlos

Hello everyone, 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 address....
