Mission planner radius field is in the meters range while copter's is in cm. Im very unsure as to which waypoint radius parameter is being used? MP's or copter's?

Hi everyone I got a couple of question regarding this command 1)Is the speed specified in the command set for the whole mission, or just before reaching the waypoint and afterwards the drone changes to the speed prior to the command? 2)This question…

"That worked?? I never tried that command since according to the API it doesn't stop the vehicle.



Evidlo said:I figured this one out too.  Just use MAV_CMD_CONDITION_DELAY to add delay commands after each waypoint.

"Yea, but i noticed that the "MISSION_ITEM_REACHED" message is thrown after the delay(atleast its like that in the simulation) and i need something to tell me when it has reached it at that exact moment. So im thinking of switchin to Loiter mode…"

"Adding an observer/listener didnt work but your first idea did, thank you very much!
I got one more question, could you point me to somewhere regarding camera control via dronekit if possible? I read something about gimbal control but nothing around…"

"Hi Javier,

As it did help quite a lot in part, see im trying to make the drone stop at the waypoint so it can execute a script from its computer companion. In order to do that in code i need something to tell me it reached it so it can execute.…"

The question has been asked before a long time ago but i havn't heard anything of it ever since. Is it possible to find out if a waypoint has been reached? Does dronekit implement this mavlink message? I'm programming a drone to stop for a few…

"Hi Chris,

That's exactly what i was looking for originally. In the hopes that you have done this before, i got three questions i hope you could answer

1)In Script.sendRC, when is the value sent when the "sendnow" boolean is false?

2)Can i somehow…"

"I dont think my original reply went through,

Anyhow, im not at home right now so i'll have to check the links later, this seems promising, Asim. I did a quick search on Ardu Pilot but im not 100% clear with what it exactly is, can you elaborate…"

"Exactly, "Your software that monitors the current location of the drone will use the predefined lat and long positions (which are basically the way point starting point prestored in PixHawk) as the software trigger to kick in the Auto Mode". Now i'm…"

Thanks for commenting and sorry for the late reply. Im not sure i quite understood the question so First thing first, this is strictly software. Two apps are going to be uploaded to the FC(PIXHAWK). Im writing an app(via uORB messaging in…"

Hi everyone,Im currently writing a program that compares the drone's current location coordinates with the waypoints coordinates so once they match a script is executed. My question is how do i access those waypoints that were loaded to the pixhawk…
