@ApoorvThapliyal Thank you for your help. also I was able to work with jazzy by only subscribing and printing with node. since error only occurred when I tried to echo the topic and not when another node is subscribing it. but using docker seems like most viable option to me since I m using ubuntu 24.04. Thank you for your help again

@Zachary-Lowell-0 Thank you for the feedback! This was very helpful

Hi @taiwohazeez, The " /fmu/in" prefix is used for sending data to the autopilot - you're never going to receive data from the autopilot listening to that topic. Look at the "/fmu/out" topics to see messages coming from the autopilot. Best, Ted

Hi @teddy-zaremba, The fusing part was a bit tricky, but it works now. Thank you!

Hi @Judoor-0, Cool! Feel free to make a MR or post the link to your code if you want someone to review it.

@teddy-zaremba Nevermind, I was able to separate the images by modifying the voxl-camera-server.conf file to treat each camera as separate and it seems to be working now

@taiwohazeez Could you post the error and we can take a look? Also here's an easier way of installing it if you just want to run this script on the voxl. wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.5/binary-arm64/voxl-ros2-foxy_0.0.1_arm64.deb wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.5/binary-arm64/voxl-mpa-to-ros2_0.0.7_arm64.deb sudo dpkg -i voxl-ros2-foxy sudo dpkg -i voxl-mpa-to-ros2 voxl-configure-mpa-to-ros2

@claw said in VOXL2 ROS2 Starling Code Inconsistencies: @Zachary-Lowell-0 Thank you for your help and guidance. Is there a way to get the status information like battery voltage using Python? Reply @claw yes you can follow this post to get battery over the DDS: https://forum.modalai.com/topic/4353/voxl2-px4-ros2-mpa-to-ros2-for-battery-voltage-problems/12?_=1745355297145

@Zachary-Lowell-0 What kind of upgrade is necessary for this Rb5? Should we upgrade the sdk? we can run ros2 foxy with it. The dds is also working. How did you build this ros2 packages and nodes https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-to-ros2 Thank you

You need to push the install folder as thats where the executables live in ros2 once you run colcon build. src folder is just the code you wrote with zero executables after colcon build is run.

@Eric-Katzfey got it, thank you for the info.

@VSK said in Stuck installing ros-melodic-pcl-conversions: configure python-twisted-core:all 17.9.0-2ubuntu0.3 <none> status half-configured python-twisted-core:all 17.9.0-2ubuntu0.3 Maybe that package got corrupted on the install. Can you try running sudo apt-get clean? If that doesn't work, you could also try removing both of the packages and do the install again. $ sudo apt remove python-twisted-core:all $ sudo apt remove ros-melodic-pcl-ros ros-melodic-pcl-conversions
