I thought some of the 3DR community might be interested in hearing that DJI has recently released firmware upgrades giving “free” waypoint capability to both the Naza and Wookong. The caveat is you will need to buy a Bluetooth data link (approx $299), but what was once an expensive software upgrade for the Wookong, and totally unavailable on the Naza, is now more affordable, particularly if you already own a Naza.
The Groundstation is available on both PC and IPad (Bluetooth 4.0 versions), the data link allows PC users to plug-in via USB or connect via Bluetooth for your fruity devices.
The video (not mine) above shows some initial testing from a user.
