trying to execute 'blinky' application. nRF52840 is connected through micro USB.
But it's not getting displayed in ''Conneced Devices' list.
When the LD5 toggles continuously it usually means there is a problem with the USB connectivity. I suggest you try with another cable and see if that helps. Just make sure the cable supports data transfer and not just charging.
Issue resolved thankyou for the timely help!
