last question :
I could not see the point cloud with stereo , but since I need it to indoor solution, I will use tof anyway.
I using the drone without any GPS module (don't need it)
but I could not to change from manual to mission nor off board.
when I change the gps to rc transmitter (first option) I was able to get move to mission
but only left stick worked (up down rotate) the second stick won't work (forward and rotation)
is there a way to move to mission without gps module?
