**************. UPDATE: The Problem is Solved by Upgrading the OSDK to the Latest Version **************

Hello,

  

I am using a M300 RTK with the Assistant 2 simulator. The M300 RTK is also interfacing with a Jetson TX2, on which the dji_vehicle_node ROS node is running. On another machine on the same network, I am executing the stock ROS mission node (i.e rosrun dji_osdk_ros mission_node). Once the mission node starts up and hotpoint mission is selected, the drone takes off in the simulator, and executes the hotpoint mission successfully. Once the drone is manually landed in the simulator, I re-ran the mission node this time selecting the waypoint mission. I keep getting an error stating that the waypoints could not be uploaded, and thus the mission could not be started. As a sanity check, I repeated this process by running the mission node on the jetson TX2 instead of another computer on the same network and I got the same results. I am running the 4.0 version of the OSDK and latest firmware on the drone itself.

The specific warning can be seen in the text below. Note that I have obfuscated the GPS coordinates manually for this post.

Any help would be appreciated.

                                      

It seems commands 'a' doesn't support M300. Command a only supports M210 v2
