TAKEOFF_LOCAL

Thank you,
I can arm the drone and takeoff, but I can not land as you said "even if the setpoint is above the real groud, the UAV will continue it's descent until it reached the ground". I set the LAND bitmask and target.z = current.z, but the drone do not land and hovering at current.z potion. Whether I need other configuration?

Thank you very much,
I finally land succeed using the bitmask by changing (0x2000 | 0b110111000011) to (0x2000 | 0b110111000111).

Sorry I was in holiday and did not see your message my bad. I do use the same bitfield you have provided for landing with px4 1.6.5. ((0x2000 | 0b110111000111)).

Did you tried it on newer version of the px4 firmware ?

Thank you

Yes I tried it on px4 1.7.0.

Hi, i am also trying to landing/takeoff using the masking bits but havent been successful. i am able to move the drone using /setpoint_raw/local topic (movement via both position and velocity works). but when i set the landing bit 0x2000 or takeoff bit, the drone stays at the same spot. here is my setpoint_raw msg for landing (the drones hovers at a fixed point). not sure what i am doing wrong.
