Yesterday I was flying my MPP from boat - just testing/comparing DJIgo ActiveTrack and Litchi's follow mode. My MPP was wearing these floats:
DJI Mavic pro Foldable Water Mod protector Yellow EDITION Drone ON Water Travel Edition
Everything was going fine for about 10 mins- after switching fron DJIgo to Litchi and back (while in air) I got a "Ultrasonic Sensor Error" as well as "Joystick Mode" on the RC. At the time I thought that the sensor error caused the joystick mode, but upon reading some old posts here I think that they may have been two separate issues that happened almost simultaneously. When both occurred, my MPP just paused in place (RC and app were still connected though) approx 30' above the water and my control sticks did nothing. I had signal loss failsafe set to hover and was prepared to just wait out the battery until it autolanded on the water. Then I thought to try RTH button and this caused the MPP to start a climb to RTH attitude- I did not want it to do this so I quickly flipped sport mode on/off to stop the RTH but this caused me to regain full control from the RC. I assume that I should have just tried sport mode toggle as soon as I was stuck in Joystick Mode.
My current thoughts: (please let me know if you disagree)
The ultrasonic sensor error was most likely caused by the floats/attachments.
The joystick mode was a separate occurrence likely caused by exiting Litchi while in follow mode.
These two issues just coincidentally happened at almost the same time (in fact, I think I exited Litchi as soon as I saw the sensor error- this abrupt app closure may have cause it to stick in joystick mode)
Does anyone think that I need to worry about the ultrasonic error in the future if NOT using the floats?
