How to convert uint8_t and Char arrays to string and int ?

How can I use ( .substring(0,7)) function in STM32CubeIDE ?

You mean C++ string objects?

const char * text = "Hello world";
std::string variable(text);

C++ strings have a substr function, if that's what you mean.

std::string new_variable = variable.substr(0, 7);

Dynamic memory allocation isn't advised on MCUs with limited processing power.
