Thanks! I just had to manually focus it.

@Nishkala I used this link - https://docs.modalai.com/voxl2-system-image/#force-voxl-2-into-fastboot

You will need the latest platform release which can be found here - https://developer.modalai.com/asset/2

I changed a few PX4 params stated in the link you posted. I stopped most voxl services. And then did voxl-calibrate-imu-temps first followed by voxl-calibrate-imu. Rebooted the drone and started/configured all the necessary voxl-services. Now I am able to switch to Position and Altitude. But not Offboard mode. Same error as earlier Check for a valid position estimate The drone is stationary on my desk and not flying. Can I only switch to offboard mode when the drone is in the air? Are there any params that I might be missing to make sure it switches to Offboard mode? Will installing a newer voxl version fix the issue?

We are having issues with our VOXL Flight. The drone is refusing to switch flight modes from Manual to Position, Altitude or even Offboard. We are attempting to fly it indoors using Offboard mode. The QVIO server is running and working fine, the necessary indoor flight params have been updated. So I am not sure what is causing this issue. The main error being outputted by QGC is "Check for a valid position estimate, Switching to mode <flight_mode> is currently not possible. I have attached an image of the list of errors being outputted.

We recently updated PX4 to the latest stable release: 1.13.0 and the VOXL version is 3.3.0-0.5.0.
Any advice on how to tackle this would be great!!

Thanks!

Cool I will bring it in today

Hi,

I picked up an order of 2 brand new Sentinel drones yesterday. One of them is having camera issues. The camera server crashes after configuration. The configuration does not show any error messages.
To see what camera was having the issue I did voxl-camera-server. This way I can see what cameras are working. The output shows the Hires, Tracking and Front stereo camera. But no rear stereo. Is it possible that the MIPI cable came loose or is just not plugged in? I can bring it back to you guys if you want to have a look. Let me know what I should do.

Thanks

Thanks for the quick response. This helps a lot!

Hi,

I would like to know the screw size of the tracking camera mount on the VOXL2 flight deck. I lost the screws when taking it apart and I want to get some more.

Thanks.

@Anton-Gereles Try to upload these parameters - https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/m500/ekf2_indoor_vio.params

This will allow you to fly outdoors without GPS using VIO.

I think this is what you are looking for? https://docs.modalai.com/flying-without-gps/

Thank you for your response!

@Steve-Turner
This is just for curiosity purposes. If I do place the tracking camera to be facing directly downwards. Can it be used for VIO flight outdoors?

Thanks!

Hi,

I have the following questions about VOA that I would like answered:

• Does VOA respond differently depending on the speed of the drone? For example, does it kick in sooner if I am flying much faster from further away? If it does not, how slow do you need to be flying in order to avoid crashing into obstacles?

• What size of obstacles does VOA detect? For example, can it detect a telephone pole or a telephone wire?

Thanks! Looking forward to your opinions and answers.

Would love an update on this!
