I do have a pixhawk mini connected with 3DR GPS on a drone
and I have run the command over ssh on a laptop:
roslaunch mavros px4.launch fcu_url:="/dev/ttyTHS1:57600" gcs_url:="udp://@10.42.0.253"
Qgroundcontrol speaks saying communication regain, and I assume that the communication is good.
However, when I try to have a fight mission, I can see that the GPS is lock (3D DGPS Lock) with over than 10 satellites, some times even more.
I can not start the mission because it says the vehicle is not ready and I can not see GLOBAL_POSITION_INT on the mavlink inspector.
I really appreciate your help.
