thank you !!

@Eric-Katzfey Thanks for the explanation, I was not starting the voxl-camera-server before. When I started the voxl-camera-server, I had my camera configuration include the tracking camera which stopped the voxl-camera-server from starting correctly. Once I changed my camera configuration with voxl-configure-cameras to "hires only" I was able to start the camera server and then start the voxl-streamer as well.

Hi AJ, It is not easy to integrate new MIPI sensors into the system. If the sensor is supported, see list here, then it is a hardware effort to integrate an interposer. There are no standard MIPI connectors, each platform is fairly different. For a new sensor, it is up to a few months of code and tuning if no reference is available. You would need access unfortunately to Qualcomm's proprietary camera stack to integrate on your own. Is there a specific module you are targeting, maybe we can help point you in the right direction?

ACCESSD16. I tried another receiver and it works, must have been a bad receiver.

@gauravshukla914 Great, thanks for the response. Glad we could help. Just FYI, that 2A 5V BEC will not properly power a Voxl, nor would any 5V supply though any of the JST or Hirose connectors, although you may see Voxl try to power up. In those conditions, be sure to use our Power Module as the main 5V so it has a successful power up. This is the only connector that was designed to support the current demand Voxl needs during power up: https://docs.modalai.com/voxl-flight-datasheet-connectors/#j1013---5v-dc-power-input-i2c3-to-power-cable-apm https://docs.modalai.com/power-module-v3-datasheet/ Be sure to reach out with any additional questions. Thanks! Vinny

A USB microphone would be the easiest path. We have never tried this though. voxl-streamer is built using g-streamer, so you should be able to mux in audio there with a little custom code

The tag won't be 0, 0, 0 unless you program it to be. You can set it to any values, and you can have multiple tags in the array (see here https://docs.modalai.com/voxl-vision-px4-apriltag-relocalization/#configuration-file) Yes, you can put a tag at say (100, 100, 0). You can fly to say (97, 100, -3), and the vehicle can see the tag and then 'infer' the tag is at exactly (100, 100, 0), and you can have the drone then fly to (100, 100, -0.5) and then land, for example.

This is how mavros behaves going from PX4 coordinate frame to ROS coordinate frame when viewed in RViz. We just supply examples of how to use mavros on our platform with open code for people to change and use as they see fit. If you have suggestions on how this code might be improved, we would happily accept a merge request.

WOW! Thanks @Lynn-Koudsi for the help, when we setup the forum this is the kind of interaction we were hoping for, just awesome!! Sorry for the setup and 'wonkyness' right now, we've been somewhat caught with getting pre-release software out there without all the setup/docs lined up.... so we're doing a little catchup it seems. @Liping there until we have our docs updated, if this is working, I'd say this is a good approach! Thank you both for the details, we'll relay this through the team.

The ipk is available here now : http://voxl-packages.modalai.com/stable/voxl-hal3-tof-cam-ros_0.0.5.ipk - you should be able to use the launch file to choose between two modes (5=short range and 9=long range) and fps, which are listed in the launch file.

@Alex-Kushleyev I see. It works and I was able to get the calibration files so it's all good! Thanks!

Looks like we used the 7" one here

Hi @Aldo-Castro-Freire , Local frame is centered wherever the drone was when it boots up aligned with wherever the drone was facing when it booted up. Body frame is centered at the drone's center of mass and points XYZ->forward right down.

Hey @gus , We have not performed comprehensive environmental testing, but expect this to perform similar to other consumer-grade electronics. VOXL/VOXL-Flight (boards with Snapdragon 820) 0-55C Ambient (validated by test), Non-VOXL stuff (e.g. Flight Core standalone), 0-70C max operating by design. Thanks!

There shouldn't be a conflict, main 'trick' is to have UDP ports setup --> https://docs.modalai.com/mavros/#configure-voxl-vision-px4

@modaltb I don't required VIO for the whole flight rn. I just wanted to test the landing. I would assume for my flights they all would be gps enable. But what gps lacks is precision on landing mostly, so I have been wanting to test how reliable is landing on top of Apriltag because we have some landing platforms and we need precision. I saw the the apriltag video and it didn't seem I needed to setup the precision landing mode, it just triggers the VIO

We offer an add-on board that exposes USB2.0 but not 3.0 as the add-on connector is a 2.0 port. VOXL has the option to be used as a USB3.0 HOST port using a custom cable, but it's not a cable that is easily found... it's somewhat of a fringe setup --> this cable pinout using this port, here's some more info
