Just recently built a DJI F450 quadcopter and coming to terms with it. Very new to this so it’s been quite a learning curve. The end goal is to get some decent videos and pictures.
The autopilot is a Pixhawk 2.4.8 and I used QGroundcontrol to load the PX4 stack firmware version 1.4.1dev. I originally tried to use Mission Planner 1.3.39 to upload the APM Quad Copter V3.3.3 firmware and configure the quad but I could never get it to calibrate the accelerometers. No problem with calibration in QGroundcontrol.
I’m using a Graupner MZ-18 transmitter and GR-24L reciever. I’ve also fitted a Tarot T-2D V2 Gimbal with a GoPro Hero 3.
All these parts seem to be working together. I’ve managed to set up the transmitter with 6 flight modes plus RTL and kill switch and the gimbal pitch control is set up on a proportional dial switch.
I’m now trying to get a handle on the automated mission side of things. I’ve managed to get it to do the basics; takeoff, move to a way point, return and land. I want to get it to fly a path past or around a location or feature with the camera orientated towards that location or feature.
QGroundcontrol includes a command to set up a waypoint as a Region of Interest, “MAV_CMD_NAV_ROI”, which I think looks like it should do what I want it to do. When I try and upload a mission to the quad with this command in it I get an error message telling me that the “Command is not supported (MAV_MISSION_UNSUPPORTED)”.
Information I got from the QGroundcontrol forum points to the error message being related to the Pixhawk firmware. So I’m asking if anybody has a fix, workaround or another approach to achieving the desired result?
