so for your STM32F401RE, try the following:
#include "mbed.h"
// unique ID test
// change this UID address to suit your model of CPU (see datasheet)
// for STM32F401RE - see chapter 24 page 831 of the following document

//
unsigned long *uid = (unsigned long *)0x1FFF7A10;
Serial pc(USBTX, USBRX); // tx, rx
int main() {
while(1)
{
pc.printf("\r\nUnique ID: %08X %08X %08X \r\n", uid[0], uid[1], uid[2]);
}
}
