This error usually means the COM port is open but the board isn’t responding—ensure the correct COM port and baud rate are selected, and that the firmware on your STM32 is running with Motor Control UART enabled. Also check cable, drivers, and that no other software is using the same port.

Hello @dineshsharma2025,

Check also Baudrate speed (set to 115200 on your snapshot).
