I fly my
P4P with multiple devices: (1) BT-300, (2) iPhone X, and an iPad. Updating software in the device DOES NOT change the settings like RTH altitude so automatic updates in device software should not have been an issue. The variables like RTH altitude, appropriately, are kept either on the drone or on the RC Controller.
I also learned, that, for the
P4P, collision avoidance does not work with leafless branches. Another important consideration, which DJI won’t acknowledge, is that in many cases, the RTH altitude must be set to a MAX altitude vs. a MIN altitude. Here in NH, I often fly under a canopy of tall trees. I need to set my RTH altitude to 30’ to avoid flying directly up into the over hanging branches.
