Have you been able to determine the distance range of the transmission from which it is still receivable?I keep getting the same error every time I fired up my birds. I tested the app today and it keeps going off and on, but it does work and displays all the drone info required by FAA. I even went 400ft AGL and it took a while, but it was reading, it needs work. I am pretty sure developers are on top of this since currently, this is the only apps that reads, and the info is pretty accurate.
