No answer from Chad, so I put the problem again here hoping someone can advice me how to advance with this topic. I took a look at the parameters send over, but there is nothing about the rotation of the board. These params are installed on my board, but the results are the same: whenever I use it for indoor, I do the accel & gyro calibration with ROTATION-NONE, but I have a roll failure detected once I try to arm and I got the visio for local position whenever I use it for outdoor, I add a M8N GPS with compass, I can't calibrate de compass because the position indicated on the QGC is different as the position of the drone if ROTATION-NONE is selected. By the modalai doc. is ROTATION-NONE that it should be used. Did I get it correctly, or do I need to select another ROTATION value of the board for calibration? Thanks!

Hi @Alex-Gardner, I followed to tune params which you suggested in above, but still am not able get optimal dense pointcloud points. Is there any alternative approach in need to follow or i need combine any other depth sensor along with existing stereo..

@Chad-Sweet Hi Chad, I go further and for the accelerometer calibration I have another issue. With Rotation None, the QGC see my aircraft on left side instead of level position, and so on. When I test to arm and take off, it see the vehicle as turn on right side and have failsafe issue. If I put Rotation = Roll 270 is much better, and I can arm and takeoff (just simulate for now). Still, I have two positions that are not right, aka it show the vehicle on: left side instead of noise up right side instead of noise down I would really appreciate your help to indicate me the right value for the Rotation to well calibrate this sensor. Thank you!

Understood. Thank you again!

It is glued to hold the focus. Turn gently, but forcefully, and the glue will break

Thank you @Chad-Sweet for your reply.

Yes, I've tried tracking->hires->stereo, that does not work. How would it be hardware if each of the cameras can run fine on their own and any combination of the two work at the same time?

Oh yes, this would absolutely cause a problem. Glad you found it. You can find just the stereo flex cables here : https://www.modalai.com/collections/accessories/products/voxl-replacement-stereo-flex-cable

Hi @Prasad-Pawar , Might be better to post QGC queries on their forum: https://discuss.px4.io/ Thanks!

Hi @shlee853 , Although there's a MIPI/CSI2 standard, pinouts can vary and the connectors on the VOXL are semi-specific, so it's not likely to find something off the shelf that can plug in. If you want to share specs here, perhaps we can point to something. Thanks!
