      I've programmed a T-impulse wristband using Arduino IDE. After some days of use I wanted to upload a new program to it but I found that it is failing to find bootloader. I've tried to reinstall the windows driver many times. The driver is sometimes recognized as STM32 BOOTLOADER, othes as appears as L073HZ something... and most of the times as unknown. It seems to be something broken in the t-impulse DFU BOOTLOADER and the configuration port is not detected anymore.
      Is there any workaround to this problem? is there any way to access to TX RX pins to program via UART?
