When I had to do the update it was kind of a Pain for me. I had to connect to the phantom 3 , then it wanted to update, but had no internet through that wifi connection. So I had to disconnect while staying in the DJI Go app, and connect to my normal wifi, download the update, then reconnect to the phantom 3 and then it finally did the update. I had no instructions or anything about the activation and how updates work so had to figure it out eventually.
Seems ok though. No issues on my end at least.
Do you guys use IOC? I didn't activate it yet, as I think you can only activate IOC by conencting directly to the phantom and PC via USB and installing the PC based software.
The waypoint, Poi, follow me modes all work when I switch to ATT mode without IOC being enabled on my P3S.
I as playing with the POI feature flying around me about 22 feet out. Way pretty darn cool.
