Hi Aristeidis,

Something is faulty. I would change usb-cable and change usb-port on PC. If does not help you can try different power source instead of USB: https://www.st.com/content/ccc/resource/technical/document/user_manual/group0/26/49/90/2e/33/0d/4a/da/DM00244518/files/DM00244518.pdf/jcr:content/translations/en.DM00244518.pdf The document describes where you can connected different voltages and what jumper changes you have to do.

Hi Pekka, Thank you for your answer. I tried to use it in a different laptop and update the firmware but I had the same result. I have a second one because I need two and the other works fine with the same code. Regarding the use of a different voltage I add a 9 volt battery I changed the jumpers as it is described in the datasheet and I connect battery wires to Vin input and ground. The code seems to run for a while (led blinks) and then is turned off completely along with the other leds or just LD4 is on slightly.
