Thanks for the quick reply.

This is a question about VOXl2 Ethernet Expansion and HUB.

[Model Information]
-system-image: 1.8.02-M0054-14.1a-perf
-hw platform: M0054
-voxl-suite: 1.4.2~beta2

VOXL2 alone works fine and works well when connected to a 5G modem.

[Questions]

1. When using Ethernet Expansion and HUB, it does not work.
   Sometimes it works and sometimes it does not work. It almost never works.
   Once it works, there is no problem even after rebooting,
   but after a day, the same symptom occurs.

In my opinion, the reason it does not work is because VOXL2 power is insufficient.

2. Please tell me the +, - pinmap for the power supplied in the photo.
   I plan to test if it works well when supplying 5V power.
   

If there is a good solution, please let me know.

Thanks,
JS, Kim

I understand. Thanks for the quick reply.

Thank you for your reply. I understand.

[Additional questions]
voxl-streamer CPU Usage increases rapidly. Performance improvement is needed. (H.265 and H.264 are the same.)

[Experiment contents are as follows.]

1. voxl-streamer CPU Usage increases gradually when using UVC camera
2. System configuration

• local : voxl2 + Ethernet Expansion and USB Hub + Wi-Fi dongle
• uvc camera modem : Logotech TOPSYNC
• Remote : Notebook, VLC Viewer

3. Experiment results

• uvc-streamer.conf : bitrate=400000 / h.265, 640x480@30
• Measurement results (after 1 hour)
  => CPU Usage : 31.3% -> 56% -> 61% -> 65% -> -----> 65.8%
  
  
  
  *I tried changing the bitrate, but the symptom is the same.

Thanks,

1. We upgraded VOXL2 as follows.
   system-image: 1.8.02-M0054-14.1a-perf
   hw platform: M0054
   voxl-suite: 1.4.2~beta2

2. However, uvc camera seems to be unrelated to voxl-streamer.
   even if voxl-streamer service is not running, voxl-uvc-server is running.
   

3. uvc camera is not affected by voxl-streamer-h.265. It needs to be confirmed.

Thank you so much.

Hi,

We are using VOLX2 and VOXL2-mini.
Currently, only H.264 is supported for UVC camera.
Will UVC camera H.265 be supported if I upgrade to SDK 1.4.1?
(voxl-streamer 0.75 / uvc-server 0.17)

Thanks in advance.

Thank you so much.

@Vinny
Please let us know the results of your USB3.0 port test.

Thanks,

@Vinny
I hope you find a solution.
We are already using V2 for VTOL drones, and are planning to use V2-mini for other large-scale projects.

Thank you,
