@ssansoy , you cannot access the data from these pipes directly, you have to use the MPA mechanisms to do that. There is an example of doing that for tflite detections right here : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-detections.c and the compiled app should also be present in the SDK, so you can run it on your VOXL2 (voxl-inspect-detections).
