    You should be able to select the 52DK by pressing the "Select Serial port button". Then, you can choose the device you want to use there. The number shown under COM refers to the number located on the bottom of the white sticker on the MCU of the 52DK. Then, nrf connect for windows will ask to upgrade the device firmware if necessary. After that, you will be able to scan to press the start scan button & scan for advertising bluetooth devices (see this link).
