Operating on a VOXL (not VOXL 2), launching the mpa-to-ros node publishes the hires, imu, odometry, and tflite frames that can all be viewed by rqt image view, but I don't see the tflite-data topic (containing important bounding box info, confidence, class, etc) that should supposedly be there, according to the modalai tflite server page. Is this data topic only a supported feature for the VOXL 2s, or am I missing something? Is there a config file I need to edit?

Thanks for your help.

Hi @jonathankampia,

The tflite_data topic should be detected by voxl-mpa-to-ros and automatically published. This is functional with the latest platform release for voxl/voxl2.

Could you share the output of `voxl-version` and the config file for the tflite-server under `/etc/modalai/voxl-tflite-server.conf`

This functionality was added to voxl-mpa-to-ros in v0.2.2 and it seems you have some very old software on this drone. I recommend upgrading to the latest sdk by downloading and flashing the VOXL Platform 0.9 release from https://developer.modalai.com/
