Hello, I am currently using VOXL2 with a dual tracking (AR0144) camera setup. I have selected C26 in voxl-configure-cameras.

When I access the VOXL Web Portal, I see that the QVIO overlay is only using the front tracking camera. However, I would like to use both the front tracking and down tracking cameras together for the QVIO overlay.

Could you please guide me on how to configure this?

Thank you.

@tkddnjs825  QVIO can only do single cam VIO.

If you upgrade to SDK 1.4.0 it will use voxl-open-vins-server for VIO by default, which will use dual-cam

@tom 
Thank you for your response.
If I upgrade the SDK to 1.4.0 and use voxl-open-vins-server, are there any additional settings I need to configure?

@tkddnjs825 Nope, if you run through `install.sh` it'll get everything setup as necessary
