@Adnaan-Yunus , Thank you for reporting this. We will try to replicate the issue.

Do you have any more specific information that could help us? For example

does rebooting VOXL2 allow you to connect from the same wifi client again (perhaps one time until it is cut off again) is there any way that you found to reset the wifi card to allow a new (previously seen) connection? have you tried setting the card to station mode and then back to softap mode? while the first client can no longer connect, can another client connect to the softap? I am wondering if the wifi card is still responsive or it does not accept any clients?

Thanks!

Hello @Tanner-Metzmeier,

We do not have a heat sink recommendation for VOXL2, however you can try off-the-shelf components, just be careful not apply excessive mechanical stress to the QRV5165 SIP while mounting the heat spreader to it (or removing it later).

Is there anything in particular that is causing VOXL2 to overheat (what type of processing)? We could try to help reduce the system load, if you provide more details on what you are actually running.

Alex

@Shantanu-Gupta please check documentation and video for VOXL2:

Hi @jon , do you always see the following warning right before the seg fault? (and never see it when there is no seg fault?)

@jon said in voxl-logger seg fault on shutdown:

WARNING, _stop_helper_and_remove_pipe timed out joining read thread

The way one would normally debug this is using gdb, but that would be tricky if you are spawning the logger from another (python) process and don't have a terminal to type in gdb (after crash) to investigate.. You could potentially attach gdb to an already running (spawned) logger.

Hello @RoyAzriel ,

If you are going to be experimenting with adding different sensors (Lidar), then Starling 2 Max is definitely going to offer more flexibility due to the larger size and longer flight time.

You should consider the dimensions of the tunnel and make sure that the drone will easily fit. I have no idea how small the cross section of the tunnel is, but if it is very small (just several times larger than the diameter of the drone), then it would be very difficult to fly due to air circulating in a small space.

What Lidar are you considering adding and what is its weight and communication interface?

The illumination will depend on your specific application, depending on how far you need to see. You should be able to add standard LED lights. if you need to control the LED intensity, you would need to get an LED with built in adjustable LED driver and optionally control it using PWM output feature on the ESC.

Are you going to develop your own mapping and navigation stack for this application?

Alex

Hi @qubotics-admin ,

Our understanding is that the voxl2_io driver should present itself as a generic PWM output (up to 8 channels) and you should be able to map any function you need to it. Although we have not explicitly tested every function. Can you please clarify which version of voxl-px4 you are using and elaborate on the "limited options" that you have for selecting the PWM function (what are you expecting to be able to set and what are the options).

Alex

@sjt277 ,

The simplest approach is to use a separate USB-to-serial adapter for each ESC.

You can set up udev rules to map and distinguish the specific usb-to-serial adapters (using their unique serial numbers) to aliases in /dev/, such as /dev/esc0, /dev/esc1, etc.

Then run your testing using different USB devices to access each ESC (i am assuming you are using voxl-esc tools?).

For example, here is some relevant information: https://askubuntu.com/questions/49910/how-to-distinguish-between-identical-usb-to-serial-adapters

Does that help?

Alex

@Roy-Azriel , the description of Starling 2 Max states that it uses VOXL2, as well as lists other major components and options for camera configurations : https://www.modalai.com/products/starling-2-max?variant=48216084087088

Please let us know what Lidar you are considering adding.

Hello @Catalystmachine ,

Sorry for the confusion. We have updated the page to be more clear that Boson is not included, see below: "(No Boson)" was added to the kit description.

The title of the product already states "VOXL 2 MIPI Boson+ Adapters for Thermal IR FPV" as well as the Kit description used to say (Before we added (No Boson)) : "PCB Adapters Only..."

The price of the Boson cameras varies significantly, depending on the specifications. You can contact a distributor to get more details. For example : https://www.oemcameras.com/product-category/thermal-imaging-cameras/thermal-imaging-cores/flir-boson-series-htm/boson-plus/ (you can find more at https://oem.flir.com/contact/find-a-dealer/)

Please note that Boson+ series of the Boson sensor is required for compatibility with VOXL2.

Regarding the pricing of the adapter kit, we do offer discounts in higher volumes, if you are interested, please send us a request: https://www.modalai.com/pages/contact-us

@SKA , I am not sure. please disable all streams except preview and try again. specifically disable:

small_video large_video snapshot

Double check to make sure:
en_raw_preview: true
en_preview: true
en_misp : true

It seems you have at least small_video enabled.

What camera resolution are you requesting? (preview_width, preview_height)
