Does PX4 now support setpoint?

I use mavros to send set point messages to a fixed-wing plane but it does not react accordingly. The problem is in the PX4 firmware as many people have pointed out. So does PX4 now support setpoint mode? What is the possible solution?

What sort of setpoints are you sending?

I don’t know what is supported for fixedwing. @dagar do you know?

I used velocity setpoint.
