      Hi there,

      I am facing a silly issue. My Core 2 runs a programme that uploads Temp data to a cloud server.
      The program runs in autostart mode, after having finalized it in Run mode, I uploaded it.
      I would like to burn the firmware again to start a new project

      The issue is that the COM port does not show up when I connect the device to my computer.
      I suspect that the program is monopolizing the COM port. I have been tryng several attempts : remove the Unit to have the program crash, shut down the program.. No success.

      Could you give me advice on how to recover my COM port ?
      Thanks for your suggestions

        You may disregard this post. I changed for another USB cable and was able to recover COM3
