On nuttx, how to exploit app for changing uav's speed, broadcast data packets and so on

Hi, all

On nuttx, I can exploit uorb to read sensors and GPS data from PX4, but I didn’t discover how to “write” custom data to PX4, just like description in this topic’s title. So, I wonder which interface can be invoked to change uav’s speed, broadcast data packets based nuttx, just like the hello world app in the nuttx.


Anyone got a solution to this? I need to know ASAP, my project is a bit time critical. Any help would be highly appreciated.

You’ll have to be more specific about what you want to do for anyone to be able to help you.
