When using waypoints with the Mavic 2 Pro and the Smart Controller. Does the controller need a WiFi connection in the field when uploading a pre-planned route for a proper map?
As you begin your journey into waypoints on the M2P be prepared to explore Litchi. It is an inexpensive alternative to The native DJI GO4 but it allows flight testing and adjusting waypoints on the desktop. Your flight missions are developed, tested in Goggle earth and stored in a library ready to use in the field. Flylitchi.com will get you introduced. I found it to be just the answer for me and more functional than the DJI GO 4.
