One more question: Should we use 5G antenna, not LTE? As I know when we buy the 5g modem the default antenna is the one with LTE.

@Cliff-Wong Thanks! I will try this as soon as possible and report how it works out.

@aspen The landing detector in PX4 isn't perfect (obviously) so in this case it didn't detect the landing. I would map one of the switches to toggle between arm and disarm so that when the drone lands you can disarm via switch. Did you try the v1.16 package?

@Peter-Milani , I see. this looks like a generic implementation of OpenCL for ARM from 3rd party (not Qualcomm), and i think it also overwrites the proprietary opencl libraries, disabling the GPU opencl support. However, you could make two separate docker images, one for each use case (cpu and gpu)

Actually, I see from the log that your FPV camera is IMX214 (please confirm).

So then my next questions are:

which Voxl2 SDK are you using? does the crash happen if you only view the Hadron EO stream (this is OV64B camera) can you please check the cpu temps when you view many cameras (using voxl-inspect-cpu)

The dmesg error suggests some sort of low level error during MIPI transmission, but it could be tied to the SoC overheating.

When voxl-portal is used to view images (especially in multi-view), the images on VOXL2 are converted from YUV to Jpeg using a software Jpeg encoder (which is very taxing on the cpu for large images). This can cause the cpu to overheat and start throttling operating frequencies to reduce the temperature). We are aware of this issue and it is on the list to fix the multi view to be more efficient and not overheat the CPU.

@N-Chen
To anyone reading this, maybe encountering the same issue in the future.
I've tested the board with a guy that has a lot of experience with the voxl2 board,
According to him, the board was faulty, probably some electrical issue, the amperage did not cross 0.1, and the board usually runs on something like 0.5.
I've replaced my board as well as my power-supply cables (which were also under par).

@Maxwell-Schaefer Thank you! I was able to set the model match to off using the controller screen.

@Muqing-Cao Here you go: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/dev/src/vio_manager.c?ref_type=heads#L450

@Eric-Katzfey interesting, think you for this information. Once i demo this drone for a couple weeks in its current BNF w/ ndaa add ons configuration I will be looking to move to a smart system and incorporating optical hold and other gps denied search features.

@ashley-miller , for this motor (28xx class), you should use the following ESC M0138 FPV ESC :

https://www.modalai.com/products/m0138
https://docs.modalai.com/voxl-fpv-esc-datasheet/

The mini ESC (M0129) is designed for small and lightweight drones and mini FPV racers (750g or less for slow flyers and 500g or less for mini FPV drones).

The peak power for one of these motor is almost 1kW each - the mini ESC cannot handle that for several reasons, such as peak current capacity, thermal.

If you would like to use the 2808 motor, please choose the M0138 FPV ESC and perform motor calibration using voxl-esc tools : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/calibration.md

Also, please review the following FAQ: https://docs.modalai.com/voxl-escs/faq/

@jeremyrbrown5 we figured it out, we just changed the name of the model to yolov8n_float16.tflite. Pretty spot on now!

Hi @Alex-Kushleyev, thank you kindly for the support and apologies for the late response. My earlier question was for an attempt to equip an M0173 to VOXL2 for a C26/27/28 config, plus an M0010 stereo pair on a M0076 interposer on VOXL J8 (sorry for the lack of clarity). Our team is now looking to use a default camera config for M0173, but minus the ToF sensor and with an added M0161 4K Hires camera connected to VOXL J8 via the M0155 adapter. Planning to test this hardware config shortly

@Jakub-Tvrz said in Starling 2 Max for indoor:

We haven't bought anything yet, but we are deciding what will be the best for our warehouse inventory application. Of course, we considered the ToF option. But you still say: "however, it is not... great" - does that mean that Starling 2 is better for our application? Or does Dual vs Triple camera for Visual Inertial Odometry also have an impact?

Depends fully on your use case. I will say that PX4's instance of obstacle avoidance is not fantastic, but it is better than nothing. In my opinion I would go w/ the model that has all the bells and whistles in case you need the hardware and decide to develop your own collision avoidance or somethign of that nature.

Hi @dylangresham
Stinger is intended to be a complete drone package for developers, integrators, and system providers who do not require additional customization. We believe it includes all the necessary functionality for the FPV use case.

Starling 2, Starling 2 Max, and the PX4 Developer Editions, on the other hand, are designed to be customizable platforms that developers and integrators can modify to suit their specific products and use cases. By design, these are not fully Blue List–certified turnkey drones, since any additions, removals, or changes made by the end developer would require recertification.

That said, because most (if not all) of the subcomponents used in these platforms are already listed on the Blue UAS components list, the end-user certification process should be straightforward. ModalAI parts will pass screening easily thanks to their existing certifications.

I hope that clarifies the rationale.

@taiwohazeez Can you post a video of it trying to fly?

@jeremyrbrown5 , it is possible that overheating VOXL2 cpu could be causing your SoftAP performance slowdown. You can run voxl-inspect-cpu which is a tool that will show you cpu usage, temps and other stats. If the CPU cores reach 95 deg C, the thermal management will slow down the cpu clock, so all the processes will run slower, including SoftAP.

@Eric-Katzfey

Thank you for reverting back. I am trying to proceed with the same approach.
I am facing some errors while going with this approach , I am trying to debug them.

Another approach :-
I am also thinking to hardcode the joystick based turtle mode to the voxl_esc.cpp.
The manual control values will be monitored and once the value of the assigned button is clicked, the turtle mode will be enabled.
Do you think it is a good approach?
