Maybe this post helps? https://forum.modalai.com/topic/1097/subscribe-to-voxl_mpa_to_ros-topics/2?_=1660186237636

The best place to start would be try to reinstall the Flight Core firmware. It sounds like the VOXL side of things is OK.

The most common failure mode for Flight Core is plugging USB into the R/C port. Any chance that happened?

We do not have any experience at this point with Microhard's meshing algorithm. You could reach out to Microhard?

Assuming you are trying to run ROS master on your VOXL, first find out what is your VOXL's IP? Let's call that <VOXL IP>

Then, can you ping that IP from the computer you are trying to run Rviz?

$ ping <VOXL IP>

If so, on VOXL edit your ROS environment

export ROS_IP="<VOXL IP>"

Then start ROS on the VOXL. Monitor the output of the ROS master when it launches, you should see the "roscore" IP the same as what you just configured.

If so, configure the ROS environment on your PC

What is the IP of your PC on the same network as the VOXL? We'll call that <PC IP>

Configure the PC's ROS environment as such:

export ROS_MASTER_URI="http://<VOXL IP>:11311"
export ROS_IP="<PC IP>"

Then launch RViz

Note: The instructions above are configuring the master to be the VOXL by pointing both VOXL and the PC to the VOXL's IP address as master. Checkout slides 7,8,9 in the presentation here

The hires channel was renamed to hires_preview, it's identical otherwise

voxl-imu-server manages the IMU by doing most of the IMU FIFO processing on the sDSP. You can find the code for icm42688 here

Please confirm you have a battery connected and NOT a wall supply

You can find details of Flight Core firmware here: https://docs.modalai.com/flight-core-firmware/ You can try the latest, but there may be a little tuning needed, etc

You can ignore that avionics power low message assuming everything else is fine. There should be more filtering on that reading and our system is measuring quickly and precisely. We should probably add filtering in the voxlpm PX4 module

Hi, we only support ModalAI products on this forum. Have you seen the PX4 support forum and Slack? That might be a better place to start: https://docs.px4.io/main/en/contribute/support.html

Here is a tutorial using mavros with kinetic.

From there you can see instructions for running Docker on VOXL that points to the Dockerfile for the kinetic image. You should be able to upgrade to Melodic using similar techniques

If you are just trying to modify the ULG file, the tools to do so are in the PX4 project here

Sorry for the late reply. the source code is here. If you have any suggested updates we would be happy to review a pull request

Did you review the PX4 documentation? It looks like it has the command set here

Have you reviewed the VIO troubleshooting guide?

I don't think we have tried mavros on RB5 Flight SDK. The VOXL SDK is close to being ready for the RB5 Flight drone. That update should enable more functionality as well as be open source. Hopefully we can post to beta in the next few weeks, we are working on the last few issues.

Have you viewed the mavros tutorial here? https://docs.modalai.com/mavros/

Yes, these fisheye modules plug in to the stereo flex adapter https://www.modalai.com/products/m0072

They are the same lens and sensor spec as the tracking sensor

It is on our to do, hopefully we can address mpa_to_ros2 at some point in the near future. If you have any code you would like to share, we would be happy to incorporate.

Have you read through the docs on how to debug VIO? https://docs.modalai.com/flying-with-vio/#troubleshooting-vio

We have never used the Flir Vue camera. The only experiments we have done with aux pwms is documented here. Hopefully that helps.
