For me it was crucial that the FlashAir card builds an access point itself. Thus, from any device (smartphone, laptop) with wireless a connection is allowed. It is sufficient to connect to the Access Point; Software on only the browser (Internet Explorer) is required. Advantage: There are no required settings on the camera. Simply take pictures with the camera and immediately bring it to the laptop via WLAN and evaluate the image. Disadvantage of the card: The browser control only one image can always be clicked on and transferred. Many photos a bit tedious. For my application (take photos and instantly judge) optimally.
