The information in the Results box shows that BLPro.exe has automatically read in the target hex file that we specified in the configuration file BL.ini, so it is ready to go.

It shows all the USB HID class devices that are connected to the PC, but our BLPro.exe only opened the one device that it is designed to open: the one device that contains and is running our bootloader, BLPro_2550.hex.

The display also shows that our BLPro.exe on the PC has automatically requested the Bootloader version information, which is equivalent to clicking Program | Get Bootloader Version.
