I am working on controlling the plane in offboard mode by sending some vehicle_attitude_setpoint messages from ground computer. I successfully controlled multicopter’s roll pitch yaw and thrust by these messages in offboard mode. I now want to make this happen in fixed wing mode, and for this, i saw that mavlink receiver publishes the vehicle attitude setpoint topic and fw attitude controller subscribes to it. But after that, it checks the modes just before sending the values to actuator and offboard mode is not in that if condition.( (https://github.com/PX4/Firmware/blob/master/src/modules/fw_att_control/fw_att_control_main.cpp#L1251) I added to that guard condition the offboard mode with an additional OR. I wonder why there is not offboard mode, i am now going to field to test this.
