how to convert received uint8_t array to string in stm32 ?

You cannot compare strings in C.

You can cast (uint8_t*) to (char*) ans use strcmp thereafter.

if (strcmp((const char *) Received Data, "Reset") == 0) {
 resetFunc();
}
if (strncmp((const char *) Received Data, "ABCDASD", 7) == 0) {
 Do something
}
if (strncmp((const char *) &Received Data[4], "ABC1234", 4) == 0) {
 ...
}

This is more a C language issue, and not STM32 specific

You can construct/re-construct a string a character at a time.

You might need to synchronize and discard characters if you receive from a serial port.

To use string functions you need to insure the data is NUL terminated.

Review C libraries and documentation. Review materials on parsing input.

For numeric conversion there are functions like atoi() and atod(), also sscanf()

Thanks for all.
