Which versions of software are you using? Are those messages appearing on QGC? Also, do not try to arm the drone or fly the drone while attached to a power supply. Only use a battery for that. If you take the drone outside with a full view to the sky so that GPS can acquire satellites do the messages go away?

With ssh or adb you can run the following at the command line: px4-ver all. You will see PX4 version and Vendor version. So, for example, for px4 version 1.14.0 and vendor version 8.134.3 then you would checkout the tag v1.14.0-8.134.3-dev from the repo to see that commit.

It would likely be a lot of software development to make it happen though

Why do I have that unpredictable behavior ? I have attached images of my controller to show the toggling i meant.

Kindly advice.

How long do I typically need to practice flying before I can buy a drone?]]>I live in Shenzhen, China, in my 30s, with a stable job and life. I'd like to get started with FPV drones, mainly to take photos and pass the time. A friend suggested I start with a simulator, which I think is a good suggestion. However, I'm eager to buy a physical drone to understand its structure, like I did when I was a kid playing with toys—very eager, but also worried about buying the wrong one. Can anyone give me some advice on what's a good FPV drone for a beginner?

But he says he needs to get on a call with the technical team. It's a year already and I still don't know much about the drones (which may be from my end, I don't know), but he wants to handle this himself this time around and get all necessary information on a single call sometime early in January 2026. Kindly let me know if this is possible, and how to go about it.

Thanks

It is possible, as the output suggests that the motion blur is causing the issue.

You can override the auto exposure algorithm and reduce the exposure down to 5ms or so to help with this. There are two ways of doing this:

using voxl-portal : open the regular camera view for your tracking camera, click a small check box in the bottom left corner to enable the advanced control panel. This will allow you to set the exposure and gain, you can try to set the gain to the max (should be 1600 (16x) for AR0144) and then play around with exposure to have the lowest exposure that still makes the checker board clear. After you are done changing the manual exposure, you can run the calibrator and switch the voxl-portal to the calibrator output.

please note that until you touch the sliders for exposure and gain, they will not correspond to the current values that are being used by auto-exposure algorithm.

from command line you can send a command to camera server: voxl-send-command tracking_front set_exp_gain 5.0 1600
(this would set exposure to 5.0ms and gain to 1600 ISO (16x))

Please note that the manual exposure settings / mode will persist until you reboot the camera server.

Once thing i noticed is that you don't have en_misp set to 1 for the tracking_front camera. I don't think this is the reason for the failure, but it should be set to 1.

Meanwhile, please try to identify which camera is causing the issue by disabling cameras and testing camera server ( you can set enabled flag to 0, so that this camera is not started.

Also, when you installed SDK 1.6.2, did you run voxl-configure-cameras and which option did you select for the camera configuration?

There is a 3-way toggle switch beside the kill switch in the transmitter (toggling down switches to position mode, toggling up switches to the autonomous mode, while toggling to the middle maintains the drone flight positioning. I have another drone that when the button is switched to the middle, it maintains the drone position (thats what i meant by hover mode). My other starling 2 drones maintains their positions when the switch is toggled to the middle position, but this particular starling 2 drone doesnt.

That is the cable that powers the VOXL. I'm suggesting you leave that plugged in and disconnect everything else. I see you still have the VOXL 2 WiFi Add-on board connected. Disconnect that as well all the cameras on the bottom of the VOXL, ESC, and GPS.

Please have the VOXL powered off while you disconnect everything.

Let me know how it goes,
Ted
