We will be adding a "connection-less" mode in the future. We are trying to work with DJI to add a mode to put it into an automated imaging interval in the event of a signal loss.
Dave is correct though. For some reason, the imaging signal drops out when the signal drops even a little bit.
We have had some really good luck using these to make sure the signal stays strong at far out distances:
The connectionless mode will basically just start the automated imaging at the start of the flight path. This will allow for beyond line of site mapping (which we don't really think is a great idea).
