    Hi! Problem statement: want to connect external FCU to voxl and communicate over the microdds bridge for minimal latency. In the past, I have tried to compile the uxrce-dds agent from source https://docs.px4.io/main/en/middleware/uxrce_dds but never really dove into trying to fix all the issues. I assume this is a problem you guys fixed with voxl-microdds-agent; is it possible to modify that package to communicate with an external flight controller over UART?

    Other option would be docker, which I've done before, but that incurs some overhead and we're kinda maxing out the voxl, so I would prefer a native implementation.

    I guess I'm just asking if this is feasible within the design of voxl-microdds-agent or if it's tailored to communicating with voxl-px4 over shared memory.

    The Serial Number generated via remote-id considered invalid when attempting to register with FAA. Currently using starling 2 max running 1.6.4~beta4.

    Referencing other messages, appears that the serial generated hard codes length character as C, which would require 12 digits. Since actual serial is 10 digits, it should be A.

    Has there been any updates to scripts to correct this?

    @Alex-Kushleyev Thank you that fixed it for J6. Is there a reason the same config doesn't work on J7? Ideally was hoping to use J7 since it works better for our layout purposes.

    I can get J6U-ar0144 and J6L-imx412 to work but not J7U-ar0144 and J7L-imx412 or J7U-imx412 and J7L-ar0144. For both it cannot find the lower sensor.

    Also is there a reason the imx412 driver does not exist for J6 upper?

    Hi, Technical Support Team,

    We need to integrate various USB thermal cameras with the VOXL2 and VOXL2 mini.

    Currently, only Filr cameras are compatible, but we need to be able to integrate USB Seek thermal cameras (320x240, 640x480, etc.).

    Please let us know if USB Seek thermal cameras are compatible with the current version, and how we can enable this integration.

    Thank you.

    Hi @Alex-Kushleyev,

    Thank you for the detailed explanation regarding the Starling 2 payload margin and the thrust-to-weight considerations. The breakdown is very helpful for my design trade-off.

    I would like to ask one follow-up regarding the Stinger FPV. In my application, flight endurance is not the primary constraint, so the shorter flight time compared with Starling 2 is not necessarily a blocker. Durability, compact size, and the ability to carry a small external sensor package are more important for this specific use case.

    With that in mind, could you please provide a similar payload-oriented assessment for the Stinger FPV?

    Specifically:

    What is the typical all-up weight of a standard Stinger FPV configuration, including battery? What is the approximate maximum thrust per motor? Using the same recommended minimum thrust-to-weight ratio of approximately 2.0 for good controllability, what additional payload margin would you consider practical? Are there recommended mounting areas or structural points on the Stinger frame for small external payloads? Are there any known limitations compared with Starling 2 regarding payload mounting, center-of-mass sensitivity, or PX4 attitude-controller tuning? For an indoor application where flight time is less critical, would you generally consider Stinger FPV a better candidate than Starling 2 for carrying a small external sensor package, or would you still recommend staying with Starling 2?

    At this stage, I am trying to make a platform selection between Starling 2 and Stinger FPV before freezing the mechanical layout. Once I understand which platform has the more suitable payload margin and mounting flexibility, I can share the planned sensor list, estimated added mass, and CAD/mounting concept for your review.

    Thanks again for the support.

    Best regards,
    Eyal
