I had no idea about this ‘feature’ of DJI drones and I find it quite disturbing that I can be ID’d / pinpointed by any old busy body or some bored copper. Having put that I’ve never actually had any bother anyway (touch wood).
I just tried to disable it on my AIR 2S using the GUI version but my firmware is too new.
The OpenDroneID app seems to be a bit crap as I got nothing on my S22 with my drone and controller both right next to it in my front room - maybe it needs to actually be flying to transmit? I hope not.
