@afdrus instead of rebooting, you can restart the server with: systemctl restart voxl-camera-server

I resolved this by doing 1 of 2 things Powercycle Add nameserver 8.8.8.8 to /etc/resolv.conf These are only temporary fixes, but get the job done so I can keep developing

@Chad-Sweet We would be doing RMA for this VOXL2 chip since it is not in recoverable stage from our tests.

@Eric-Katzfey Thanks Eric, for future readers, I've created a new post at Voxl 2 Spektrum RC Issue.

Hi @Aks , Out of the box no, but if you are recompiling SW yourself than it's likely doable, but we have not tested this. voxl-px4 utilizes the DSP for it's IO on VOXL2, do the UARTs aren't exposed to Ubuntu like a normal UART (/dev/ttyHX). Instead it's a little deep in voxl-px4 at this time. The current production release is a 1.12 based branch, called voxl-dev-1.12. For example, the QUP2 port is defined here for the ESC: https://github.com/modalai/px4-firmware/blob/voxl-dev-1.12/src/drivers/uart_esc/modalai_esc/modalai_esc.cpp#L42 And QUP7 is defined to be used by px4io here: https://github.com/modalai/px4-firmware/blob/voxl-dev-1.12/platforms/qurt/src/px4/generic/generic/px4io_serial/px4io_serial.cpp#L67 For reference, I used my own graphic to remember the QUP indicies, here: https://docs.modalai.com/voxl-px4-developer-guide/ specifically: https://docs.modalai.com/images/voxl2/m0054-px4-block-diagram-0.4.png Although we haven't tried this, you may be able to recompile with updates here to the QUP index and get things going that way.

Hi @modaltb, We were making a mistake of connecting the mavros with the UART which is being used by mavlink server, hence creating the traffic in communication. Now we are connecting mavros with VVPX4 and it's working fine. Thanks.

A small observation from my side. While we are flying the quad indoors with compass disabled and using a external optical sensors (in both cases) the qvio recovers itself even after force restarting it using terminal, but the same does not recovers itself outside. For both the cases the exposure and gain of tracking cam was in auto. Can you tell us what might be the issue

Thanks! this is helpful confirmation

Hi @Aks I will need to investigate, our beta releases are subject to bugs as they've not gone through our standard test flow and are generally provided to end users to test out a particular feature. So I do not trust the beta image for flight at this point, we've not posted one of these beta images publicly so if you have it it's likely to test a one off feature and not recommended for flight...

On this note. Does anyone know what happened to the hellocl repo? The link on the Build Applications for VOXL, VOXL 2 and RB5 Flight page in the docs does not lead anywhere anymore.

Thanks, for your quick response @Chad-Sweet . We have already flight tested part of the setup above (except HereFlow), and it seems to work great. Please find connection details in the attached picture below:[image: 1677928974590-voxl2_sysarch.png]

Hi @Aks , please refer to other thread where I have some info, thanks!

Kind of. I'd just like to know where the origin is of the IMU data reported by the voxl-imu-server MPA service (as quoted above). If it's at the center of one of the specific IMUs then that link is comprehensive to figure out the dimensions. But I haven't been able to find where that origin is. My guess is at the center of the board, but I'd like to confirm.

@Matt-Turi Thanks !!

That is not well supported in PX4 1.12. We are working on a PX4 1.14 port which should be much better supported. We hope to have an early access beta release of that in the end of March or so

In the end the issue was my laptop which was not powerful enough to support the graphics of the 3D visualization.

You need to use a supported camera configuration. You cannot plug different sensors into different locations. C6 and C9 are supported for TOF. https://docs.modalai.com/voxl2-camera-configs/ If different sensors are plugged into different locations, undetermined behavior will occur

@張為超 It worked. I setup my Pc as the master this time, and it worked in that way.
