What is the function of the push / pop instructions used on registers in x86 assembly?
...s r/m, not just register, so you can push dword [esi]. Or even pop dword [esp] to load and then store the same value back to the same address. (github.com/HJLebbink/asm-dude/wiki/POP). I only mention this because you say "not necessarily a register".

From the app side I have a text box that is sending the string to ESP32, all working except when I try to send strings over 23bytes. Ok, I read some topics here and tried to apply those solutions but no success yet.

Is “for(;;)” faster than “while (TRUE)”? If not, why do people use it?
... while(42) is the coolest, produces no different result with respect to while(1) or while(true) or while(!0), and has philosophical meaning. I suppose for(;;) is parsed faster than the others anyway
