That not error, just your FCU don't support version request. See #96, #236.

TarekTaha · 2015-03-09T12:46:08Z

I am using the latest px4 code, is it implemented yet ?
Does this error cause any serious issues while using mavros ?

mhkabir · 2015-03-09T12:48:16Z

Its not an error. Just a warning. PX4 doesn't support the request yet.

It doesn't affect runtime in any manner.

Weird, because I just updated my mavros code, last commit I used was 16f03ea for some reason I can't seem to have the vision estimation working with the most recent commits (localX,Y,Z are not being updated) and the light doesn't blink green. /mavros/position/vision is getting the location as usual. Any idea why this might be happening ?

vooon · 2015-03-09T13:45:02Z

Because #241 and #233 -> /mavros/vision_pose/vision.

mhkabir · 2015-03-09T13:51:25Z

Actually, also PX4 has removed inav from being default estimator for
multicopter.

Now ekf_att_pos_estimator is default but it doesn't support vision
estimated.

Change the default estimator in the ROMFS script or use the NuttShell to
stop the EKF and start inav.

@vooon Perhaps add a note to wiki.

mhkabir · 2015-03-09T13:53:20Z

Also perhaps we should change topic name to

/mavros/vision_pose/estimate

so that it seems a bit more clear?

TarekTaha · 2015-03-09T14:15:33Z

Thank you @vooon and @mhkabir , now it makes sense and it works just like before.
@mhkabir you might have to update the wiki here https://pixhawk.org/dev/offboard_control/testing and change the topic names:

/mavros/position/local -> /mavros/local_position/local
/mavros/position/local -> /mavros/setpoint_position/local_position

mhkabir · 2015-03-09T15:22:20Z

@BlackCoder. Its a wiki. Feel free :) I'm all booked for this month.

TarekTaha · 2015-03-09T15:55:11Z

Done , @mhkabir I was more than happy to do it, just I wasn't sure that it's appropriate to do it at this stage since renaming/re-factoring is still in the process

mhkabir · 2015-03-09T16:28:26Z

Now that you say it, I think we might have to discuss the naming once again.

Currently, @vooon , the names don't sound quite right. Perhaps discuss this
on Gitter?

I think better in tracker (so we could link them as #49).

Created #247.

sahara-RAL · 2021-06-13T14:25:38Z

I launched gazebo using make px4_sitl_default gazebo.
I launched mavros by this command roslaunch mavros px4.launch fcu_url:="udp://:14540@192.168.1.36:14557".

but when i am trying to rostopic echo /mavros/state that is not printing any output.

version: Kinetic
ubuntu 16.04
