send mavlink message to px4 by udp

i want to do offboard control by using matlab to control px4.

im trying to send command (mavlink message) to px4 by udp .

for example , i give the thrust command like the picture. but nothing happened for px4. (i run px4 software in the loop with gazebo on my desktop)

do i need to do something before giving a command? or is that not the way to give command to px4??

sorry for my poor english.

i will be appriciated with any kind of clues for this, thank you !!

MAVLink provides the Path Planning Protocol that enables the offboard control of the drone. Did you take a look at that?

thank you for the answers!

I just have looked at that but I couldnt find that they support Matlab.

also I know that px4 support python and c++ for offboard control. but they are not what i wanted

I want to control px4 with Matlab .. I wonder if there is another way

thank you so much :)

Hi,

As mentioned by @Ankur Bose you can use the Path Planning Protocol to send a TRAJECTORY_REPRESNTATION_WAYPOINTS message to control the px4 in offboard mode. The MAVLink is independent of the language use to generate the message.

Hope this helps !!
