Trouble initiating 2nd mission after one completes

Posted by Eben N. Broadbent on May 26, 2017 at 1:18pm

Using an m600, I flew a nice mission using the UGCS beta app (android). However following landing UGCS disconnected from the drone, and I was not able to get it to connect again. I restarted the app a few times, turned off UGCS on my PC and restarted. The drone was in good health as I checked via DJI Go. I'm guessing the solution would have been to turn off everything and start over? 

On another note, it would be great if the UGCS Android App displayed telemetry (location) information as well. Perhaps it does, but I couldn't find it. I was thinking, what would happen if my PC battery died and I was BVLOS? I would have to either hope it continued the mission successfully, or press the return to home button with no idea where it was (unless I opened DJI Go I guess).

Thanks!

    Thanks! I'll share the logs later today. For notebook battery, I guess there is also the controller RTL button if in range and comfortable the safe altitude won't go through an obstacle or terrain.

    Regarding second question - currently UgCS for DJI app is a bridge between UgCS on laptop and drone. In feature we will implement limited GS functionality on android but now in case if notebook will died when your drone is airborne you can use DJI GO to return it back. If you will have radio link wih your drone, of course... Usually 2.4ghz radiolink will be lost first in case of BLOS flight...

    Hi, to diagnose connectivity problems we need to see logs from your mobile device and laptop.

    Logs can be found in the following locations:

    Windows PC
    C:\Users\ [USER NAME]\AppData\Local\UGCS\logs
    Android device (if you use UgCS for DJI app)
    Device storage > Android > data > com.ugcs.android.vsm.dji > files > log_cat
    Mac OS X
    /Users/[User Name]/Library/Logs
    Linux
    /var/opt/ugcs

    Please collect them and send to support@ugcs.com

    From my personal experience most probably cause is a DJI GO - if you started this app after landing it can get access to port and to connect UgCS again you will need to remove both apps from device's memory and reconnect USB cable.
