Hi, I'm using ST Core for the Blue pill. I use a stlink v2 to upload the sketch (I use arduino IDE). My sketch is here: void setup() { Serial.begin(9600); Serial.println("ciao"); delay(3000); } void loop() { } Ofc I use the USB as a serial and my arduino ide can recognize the blue pill in t…

Ah. I misunderstood. Insert a loop after your Serial.begin() - USB ports take some time to initialize: void setup() { Serial.begin(9600); while (!Serial) { delay(1); // wait for USB to enumerate } Serial.println("ciao"); delay(3000); }

I believe that with USB support enabled, it will be the USB CDC connection that is called "Serial", and you'll have to find a different name for the USART Serial (probably "Serial1" ?)
