The idea behind the Easy Tools feature was to make the drone as resourceful as possible for anyone who wanted to use it for more than just a simple flight.
Right now the world-wide communication standard is the USB cable and almost all the devices give possibility to use it. If not, there is a wide variety of USB-based adapters which can be used instead.
Therefore all technical equipment can be connected via the USB cable, mounted on the quadrocopter and finally, using the Easy Tools, accessed via its own software on the Ground Control computer just as if it was connected to one of its ports.
Easy Tools uses the USB over the IP technology and brings it to the whole new level.
