Truth 2 "and DJI sends a brick command to all of their drones. Your drone would still need to be connected to the internet to receive that command." that is sort of true ...... but .......
The fly app needs to connect to the internet occasionally to either prevent a log out or to log in after the log out. If a "brick" command is passed on to the fly app during this connection then, when the app is 'next connected' to whatever, that command might may be passed on to either the drone or the controller and bricking the controller would ground the drone.
I would think it is unlikely to happen but given you [insert word/s] ..............................
One, or more, questions, has anyone with good to very good radio knowledge actually stuck a drone, controller and the app in a lab and monitored what signals they send out at all stages of their operation ?
Have the [insert words] done that ??????????????????
A numpty like me can think of two major groups of signals, control and the FCC caused RID.
The former is, as far as I am aware, fairly short range and possibly directional due to lobes.
RID I have no idea about.
Other than that, wifi communication from whatever hosts the app is, apart from the login stuff, at our discretion .... isn't it ?
Or are the [insert words] suggesting that something is either broadcasting in secret or piggy-backing on a legitimate signal .... if the latter, to what are they transmitting the signal ?
