Consistent camera not found (M00014 and M0076 or M0135)
-
Hi,
The error is probably very obvious but I'm just not able to see it at the moment.
We're trying to setup a new voxl2 mini with a tracking camera, but we simply cannot get the camera recognized by the voxl-camera-server. I have tried with both M0076 and M0135 interposers.
For example, if we try to replicate the setup from https://docs.modalai.com/voxl2-mini-image-sensors/
for just the tracking camera, that means connecting M0014 to M0135/JU to J7 on the voxl2 mini. None of the other camera are connected, for now we're just interested in the tracking. We can try the same with the M0076, but I just want to follow this image explicitly.
Once I do this I configure the camera as follows:

No ID lets the camera server find a camera.
