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.

Mind+ 掌控板、ESP32开发板等硬件如何接入AppInventor?
由于硬件板种类繁多,这里仅讨论硬件与AppInventor的通信方式,及使用什么组件。一般不外乎2种方式:
1、蓝牙(经典蓝牙),使用 蓝牙客户端 组件。Mind+ 参考代码如下:
