What version of voxl-suite are you using? If you could send me the output of `voxl-version` that would be really helpful ## Reply by jbiscan21 · 2026-07-27 18:45:12 UTC (in reply to ApoorvThapliyal) @ApoorvThapliyal Hello, I am using 1.6.3. Here is my attached output.

What is your camera config? I am guessing the mpa to ros2 node is bridging both camera and IMU? ## Reply by jbiscan21 · 2026-07-28 21:28:46 UTC (in reply to brahim) @brahim Hm, after a few reboots and trying again a few days later it is working. Do you know where this package lives so I can inspect the source code? I am not sure what the ros2 node is doing but I do see topics relating to imu and camera data. I have the Starling2 Max C29 config in regards to sensors. ``` ing2-max (D0012):~$ ros2 run voxl_mpa_to_ros2 voxl_mpa_to_ros2_node Found new interface: yolo11_tflite_data 2026-07-28 21:25:30.085 [SUBSCRIBER Error] Deserialization of data failed -> Function deserialize_change Found new interface: hires_front_large_color 2026-07-28 21:25:36.819 [SUBSCRIBER Error] Deserialization of data failed -> Function deserialize_change Found new interface: hires_front_large_encoded Found new interface: hires_front_large_grey Found new interface: hires_front_small_color Found new interface: hires_front_small_encoded Found new interface: hires_front_small_grey Found new interface: hires_front_snapshot Found new interface: tof_conf Found new interface: tof_depth Found new interface: tof_ir Found new interface: tracking_down Found new interface: tracking_down_bayer Found new interface: tracking_down_misp_encoded Found new interface: tracking_down_misp_grey Found new interface: tracking_down_misp_norm Found new interface: tracking_front Found new interface: tracking_front_bayer Found new interface: tracking_front_misp_encoded Found new interface: tracking_front_misp_grey Found new interface: tracking_front_misp_norm Found new interface: yolo11_tflite Found new interface: imu_apps Found new interface: imu_apps_body Found new interface: imu_apps_notemp Found new interface: imu_apps_raw Found new interface: imu_mavlink Found new interface: tof_pc Found new interface: voa_pc_out Found new interface: voxl_mapper_aligned_ptcloud Found new interface: vvhub_body_wrt_fixed Found new interface: vvhub_body_wrt_local Found new interface: ov Found new interface: vvhub_aligned_vio ``` ## Reply by brahim · 2026-07-30 21:31:07 UTC MPA to ROS2 can be found here: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-to-ros2
