@abachhu ok, thanks. I'm giving that a try now

abachhu

@abachhu

I am not sure how to proceed from the error I have now tho

John Vernon

@johnv757_twitter

I'll let you know if I have the same problem or find a solution to it

Just updating in case anyone else runs into this problem: In my case, it was that the heartbeat was coming from the ADSB. I didn't have to build from sources, I just had to set the ADSB serial interface protocol from Mavlink1 to None. While this disables ADSB for me, it will work for now.

abachhu

@abachhu

@johnv757_twitter where can I find the Mavlink1 command to change it to none and try?

Howdy. I can successfully connect DroneKit to SITL and to a Matek wing (by increasing the connect timeout.) Yay! However, I'm currently experimenting with the SITL and I'm getting "Mission upload timeout" when uploading mission commands over a TCP connection. Any ideas? I can't even find "Mission upload timeout" in the DroneKit codebase!

It doesn't fail all the time. Just almost all the time.

egradman

@egradman

It succeeds when I upload (home_waypoint, takeoff, wp_0) but fails with a mission upload timeout when I try to add any more waypoints to the upload. In the success case, the plane takes off, reaches altitude, and immediately RTLs without flying to wp_0. But that's a different problem I suppose.

Has anyone been able to use AIRSIM with Dronekit?

@Jack-2025 we have a GSoC student (@rajat2004) adding a backend right now for AirSim. It's over here: ArduPilot/ardupilot#11367 . Note that the current protocol over there isn't what we're going to use eventually - we're looking at moving t o something more flexible (probably JSON-based).

Were you able to use dronekit with AIRSIM?

Can anyone tell me how to use dronekit with airsim simulator

Were you able to use dronekit with AIRSIM?

Rajat Singhal

@rajat2004

@ddomit AirSim works like a Physics backend to ArduPilot, so you can use dronekit like used normally with SITL

Hello does anyone have any idea how to send specific PWM signals to an individual motor or motors at a time. For example have one motor go at like 40% throttle and then two motors go at 10% throttle at the same time. If possibly have a motor/motors ramp up slowly so like go from like 0% throttle to 50% throttle slowly.

Hello All

I wanted to use python API for connecting drone and getting current location of drone. SO can anyone please guide me how I can do it?
As I am having DJI Mavlink drone, which connects with WiFi.
So please help me for this, its really appreciated

How to draw a circle in dronekit guys? Since yaw and yaw_rate not supported in messages, how we can accomplish this

Hi i'm trying to run a sitl script I get ERROR arming motors and then it takes pff and after a few seconds it says error DISARMING motors. Has anyone come across this. The same script works on another machine. Not sure if its an issue with dronekit or dronekit sitl itself.

Hi guys ,

dronekit-sitl Copter

Everytime the simulation initializes with FRAME_CLASS 0 . And I have to manually set the frame class as 1 from Mavproxy.

Is there any way I can make FRAME_CLASS 1 permanently??

Hi everyone! I'm new to dronekit but have an issue changing mode in one of the tutorials (https://dronekit-python.readthedocs.io/en/latest/examples/simple_goto.html).I launch the SITL copter then the simple_goto.py script, but the drone disarms automatically after take-off (only reaching 0.02 altitude). After checking it seems the copter doesnt seem to switch to "GUIDED" mode. I've tried adding some wait after the "vehicle.mode = VehicleMode("GUIDED")" command but the mode still stays in "STABILISED". Any thoughts? Thanks in advance!

Jawad

@itzmejawad

Hi @graeme204marble ... It seems you're experiencing the same problem of dronekit-SITL as mentioned here dronekit/dronekit-sitl#142 ....Just give a try

graeme204marble

@graeme204marble

thanks @itzmejawad , however I didnt manage to get it to work. I'm on Windows and dont seem to have a /.dronekit/sitl/copter-3.3 folder in my virtual environment (but maybe it's called something else on windows?)

Jawad

@itzmejawad

@graeme204marble In windows there will be executable "apm.exe " file which gets executed when u call dronekit-sitl copter

like /.dronekit/sitl/copter-3.3/apm.exe..

I have no idea how u r going to locate this file in windows and also how ur going to replace it with custom binary :(

Hi guys, I'm quite new to dronekit. I would like to access all the prearm health check on vehicle using python and store them in a database. Is there a list of prearm paramaters for me to check.

my vehicle mode keep in stabilize mode , and i cannot change it in SITL. Does anyone know how to solve it?? Thank you

Hello everbody, I was running ArduCopter sitl and dronekit for my project. I could able to send condition yaw and set position target for x,y,z velocities. But when I change to ArduPlane fixed wing these commands are not working any more I'm getting COMMAND_ACK: CONDITION_YAW: UNSUPPORTED for MAV_CMD_CONDITION_YAWmessage and when I try to send set_position_target_local_ned_encodemessage for pitch or else I don't get any error excep COMMAND ACK: DO_CHANGE_SPEED: ACCEPTED for my pre-defined change speed function in this case my speed is not changing. Lookslike everthing is running differen in ArduPlane SITL. Also I was reading dronekit and ardupilot wikis' but I couldn't find commands/messages that sorts my request. What should I do :/

@norisg

I have a fundamental issue how flight modes work on dronekit, I am trying to explain my problem a bit:

So checking the MAVLINK doc there exist only MAV_MODE (e.g. MAV_MODE_MANUAL_DISARMED, MAV_MODE_GUIDED_ARMED) and there is no FLIGHT MODE naming in the MAV doc.
Now I am trying to understand how these MAV_MODES correlate to the FLIGHT MODES of PX4 for example, because the I have the following modes according to their website:
Manual-Easy: Position, Altitude, Manual/Stabilized, Orbit
Manual-Acrobatic: Rattitude, Acro
Autonomous: Hold, Return, Mission, Takeoff, Land, Follow Me, Offboard

Nobody

@norisg

I am a bit confused now, because when I try to set the MAV_MODE to MAV_MODE_GUIDED_ARMED via the following commands
COMMAND_LONG {target_system : 0, target_component : 0, command : 176, confirmation : 0, param1 : 216, param2 : 0, param3 : 0, param4 : 0, param5 : 0, param6 : 0, param7 : 0}
a print out of vehicle.mode says I am in VehicleMode:POSCTL

so how does dronekit map the MAV_MODE to PX4 MODES?

Because I want to control the modes my the MAVLink messages

Nobody

@norisg

Does Dronekit support MAV_MODE message in general ?

Nobody

any way to reset SITL Battery to 100%

@ahmetozkaraca

Hello Everyone, ı think dronekit have a bug for serial connection. Because sometimes it gives no heartbeat error. I am trying to solve this problem for a week. But I can not solve that problem

Guohao

@Guohao91

@ahmetozkaraca It's caused by the connection between the FC you'r using and the companion computer,

not the dronekit's issue

@norisg Dronekit supports MAV_Mode message

you can change the flight mode during fly
