Guru Meditation Error: Core 1 panic'e with free [RESOLVED]
Posted: Mon Jun 01, 2020 4:16 pm
Hello ,
I would like to recover the result of my serial2 link. It's a char by char and concatenate them. I use pointers, my code works once when I don't free memory with free() function. When I want to free the memory after use I have directly one problem problems.
I put two pictures one with free, one without.
thank you

data=strcat( data, data1 );
