I cant get it to compile for my ESP32 :/ I'm getting errors (attached below) even while compiling the example program, I think it's because each "byte" of the MAC address is declared as unsigned int ...
Why does it say its an unsigned int? I am passing the arguments which the function wants from me. Can someone tell me whats wrong? Or alternatively provide an example how to use the function? Thanks ...
