Hi, I'm Luca, and I'm currently working on the ModalAI voxl2 mini. Thanks for your help and your quick answers.

To recap: I ran voxl-camera-server -l, and I got:

Instead of checking the Cam slot, I have to check Cam idx. So I ran the following command: camera-server-config-helper tracking:ov7251:0 tof:pmd-tof:1 and got the following output:
