@tom @shawn_ricardo Thanks very much - ill give that a try

@tom I haven't tried the ethernet port yet. I have used the physical USB port with a WiFi dongle and that worked well.

@tom that's cool we will take a look at that in the future.
Any idea why I cannot use the J12 port on the ethernet expansion board?

This solution doesn't work

That's my working solution

@tom ill do that tomorrow when I'm back in the office

@tom Cannot ping the modem and I am certain its a free IP address.

I tried a USB Expansion Board with Fastboot v2 I had on another setup and it works so the issues does seem to be on related to this board.
Is there a jumper I need to set to enable the J12 header?

Hi,

Can I connect a doodle lab radio to the J12 connector on the Ethernet and USB Hub board?

I have connected it and ran voxl-configure-modem

When I check ifconfig eth0 the IP details looks correct but I cannot ping any other IP address on the Doodle network.

Thanks a million @Alex-Kushleyev that certainly explains the effect - I really appreciate you taking the time

I understand now @Alex-Kushleyev thanks for the explanation

Hi @Alex-Kushleyev I have changed to the EIS drivers in order to test the MISP (you kindly gave me that information on another post) and I am not at all certain the same issue exists on these drivers.

I know that I was testing with the default small and large streams (1024x768 and 4056x3040) and if I change the FPS to any value other than 30fps the digital zoom effect occurred. I would need to go back to the default driver and settings to double check.

However, I am likely to stick with the new drivers as they are very impressive so we could park this question for now.

Thanks a million @Alex-Kushleyev

I assume the camera is run in sync'ed mode to produce clearer images for computer vision purposes - is that correct?
If that is the case would changing driver potentially reduced the tracking accuracy?

Aidan

@Alex-Kushleyev understood,

Thanks again I will give this a try - fingers crossed

@Alex-Kushleyev thanks a million for this information (and the beta drivers) Alex it is very helpful.

I am using voxl-camera-server version 2.1.1 (voxl-suite 1.4.1)
From your information I will try 3840x2160 and 4040x3040 at 60fps to see what the performance is like.

Aidan

@tom I have done that are there are three potential resolutions.
However, only the 1936x1080 produces a valid stream.

When I capture a raw bayer at 4056x3040 then the majority of the image is black. It is as if the 1080p image is put into a 4k container.

Any ideas what I could be doing wrong?

@tom I was giving imx412-fpv-misp a try and was wondering can the resolution of the stream be increased?
Changing the values in the voxl-camera-server.conf file results in a corrupted stream

Cheers @tom ill give it a try

Hi,

I see in the voxl camera server gitlab project it mentions imx412-fpv camera - what is required to enable this for testing?
It doesn't appear as an option on the voxl-configure-camera script.
