Perhaps someone from DJI can help me answer this question. It's more for my own curiousity than anything else.
How does DJI test for 'no signal' or 'disconnected' errors that are seen by the end user (in this case, me)?
Do they take the drone out and fly it in an open area to try and replicated the fault?
Do they have some sort of monitoring/metering device that will test the signal strength of the remote and the aircraft while in an isolated room/building?
Hello sir, the environment plays a very important role when flying, while it's also related to the mobile device you are using, the way antennas pointed, please make sure firmware for remote, aircraft and DJI GO APP is coincident with each other.
