PX4 in SITL

[johan606303]

Hi.
I am trying to set PX4 in SITL mode.
The commands : git checkout v1.10.1 and git checkout v1.10.2 .
So I tried with git checkout v1.11.0-beta1 and I arrived to :

So after I modified Settings.json :

But when I run a project, run-console.bat returns the following issues :

And on UE4 I have the following messages :

What do I have to do else to control the drone using Python ?

Thanks for your help.

Are you running the latest AirSim master? If not, then try with that, several issues with PX4 have been fixed very recently

[johan606303]

Do you mean run the command git rebase origin/master ?

[rajat2004]

git fetch origin
git rebase origin/master

[johan606303]

Well I ran those commands, it returned to me :

So the issue is a bit different. But I forgot to mention that when I run a project, when UE4 appear and I press Play, VS2019 says that i meant breakpoints

And when I clic continue :

You might be running into the problem discussed in #2583
@lovettchris would have a better idea
Just to confirm, you're not running in HITL and only SITL correct? Also, are you using any joystick?

[johan606303]

It's for SITL, and I don't use joystics, I don't have any remote controle. I want to controle just through executing codes, at least for now.

[rajat2004]

Just to check if the current latest master is being used, could you put the last commit id
git log should give the list of commits

Also, did you run build.cmd and then update_from_git.bat to update the plugin

The heap corruption in AirSim was fixed with this PR #2634, can you make sure you have those bits installed ? I built this fix into these binaries, and I've tested those binaries with PX4 v1.11.0-beta1:

• AirSim Neighborhood binary (1.3gb)
• AirSim Blocks binary (153mb)

I also see in your screen shot where it talks about lighting needs to be rebuilt, so I wonder if Unreal is still compiling shaders in the background, which could create some timing problems... My pre-compiled binaries will not have that problem. This shows a python script flying the above AirSim Neighborhood using PX4 SITL v1.11.0-beta1:

@rajat2004 When I run git log I have :

[johan606303]

Well I ran commands build.cmd, and update_from_git.bat. Then when I ran the project Blocks, here there are no breakpoints but on PX4 run-console.bat I have :

and on UE4 :

Then if I try to run api armDisarm(True)

and on UE4 I have :

@lovettchris Thanks, I'll test these binary.

[johan606303]

@bys1123 Hi, does it work for you ?

[bys1123]

#2649
@johan606303 Not yet, here is new PR and new binaries, might works.

[johan606303]

Ok, thank you for the link.

[johan606303]

@lovettchris Ok. I tried to run with Blocks or Neighborhoood, that @bys1123 sent me. But I still have those issues, and I con't understand why. On run-console.bat :

Thank you for explanation and help.
and on VS 2019 when I try to run some API python commands, it sends me an exception :

Something is wrong with the GPS, but I defined them in settings.json as on tutorial :

Or running PX4 in SITL rearly requires to connect and exterior device ?

Or is there a parameter that is missing, perhaps : LPE_ALT. Because I have just noticed that are indicated parameters LPE_LAT (for latitude), LPE_LON (for longitude), but not altitude.

Thank you for explanation and help.
