Hello
I am new to this site and I have a problem with turning on an esp8266 or WEmos as a transmitter and an esp32 as a receiver. I use the site
https://randomnerdtutorials.com/esp32-esp-now-wi-fi-web-server/
I use the ESP32 receiver as is.
When I send the mac address FF everywhere in the mac address it works but on the other hand when I put the correct mac address (which has been verified) in other programs I have an error.
Here is an image of the serial ports which shows us the error

Here is the transmitter program for esp8266

I have a google nest router. (Mesh network) Can there be some link with this router.
