I have a wifi-only iPad Air 2 and I love the big screen for DJI Go, but the wifi version does not have a GPS chip so I don't have GPS capability for flying, mapping, etc. I know there are bluetooth GPS units that can communicate with the wifi iPad 2's, but don't know if that info is available to the DJI GO program. Many posts about Bluethooth GPS's comment on their limited functionality and that not all apps can access the GPS info. (Note: Bluetooth is necessary because the other GPS units for iPad use the Lightning Connector which I need to attach the controller.) So, has anyone actually used a Bluetooth GPS unit with their wifi-only iPad Air and confirmed that it makes that GPS data available to DJI GO.
