HP LapTop. Tried drag and drop of .hex file as instructed to the E:MBED drive as well as "blinky", downloaded and compiled on the BLE and dragged and dropped the hex file. Note other than mbed.html no other files are in the E: drive. Should I copy and paste?

Have you mounted the BLE Nano onto the MK20 USB board correctly? See the section of "Hardware Setup":

http://redbearlab.com/getting-started-nrf51822/

Note the MK20 has 7 pins in symmetry, while BLE Nano has 6 pins in symmetry, so you should be careful when mount BLE Nano on to MK20.

The 1st pair of pins (counting from USB Port to the Right)are skipped over on the MK20 and the last pair (6th to the right) of the BLE Nano pins are inserted into the last pair (7th) of the MK20. The fail.txt file shows up and no blinking on the MK20.
