Since the NANO USB stick has no I/O connections or LEDs for user interface it is recommended to
use a standard CC2531 USB dongle for SW development and prototyping before loading the code
onto the NANO USB stick. The NANO USB stick is compatible with regards to USB interface and
radio interface to the standard CC2531 USB dongle.
