Thanks for replying.
It’s not obvious how it can be checked, since Pix4D Capture doesn’t have an option or menu where we can see the number of channels available, or on which one we are.
The difference between FCC and CE - are that in DJI Go you can see 13 2.4Ghz channels for CE, where if you are in FCC, you can only see and select 11.
So, if Pix4Dcapture doesn’t change the GPS mode, but still recognises your location, based on the GPS settings (for example, set in Fake GPS) - then it is not clear if it uses FCC or CE mode when communicating with the drones and controlling them from the controller.
Again, this FCC/CE mode has no relation with the wifi mode on the smartphone.
The question is - what mode does the Pix4D Capture app use ? It’s important since in CE, the range is vastly reduced, and the app will command the drone to return home if it loses signal, and that can happen after only 100-200 meters, inside zones with many radio and electrical interferrences.
