@Jetson-Nano I highly recommend you spend a couple hours going through this: https://docs.modalai.com/voxl-developer-bootcamp/

Wow I didn't know there is dedicated apt package to install ros-foxy and why the guide leads to install ros via script.
Anyway thanks for the comment and I will try to install as you mentioned.

@Alex-Kushleyev

Thank you for some comments. I was able to be streaming, recording and video playback well!

I will be more considering about image preprocessing.

@황대현 Please read further down in the document where DSP UART is discussed https://docs.modalai.com/voxl2-external-flight-controller/#dsp-uart-to-flight-core-v2

Hi.
I try a test on voxl-mini with your advice applied.
voxl-mini sdk version is 1.0.0
My program and spi device operates is normal.
Thanks for your advice.

@Κωνσταντίνος-Κλέων-Χριστόπουλος In that case we can't help you with SSH or WiFi, that's not our hardware

@kclee2001 , if I understand correctly..

you are connecting a USB camera to voxl2-mini and using voxl-uvc-server to read the camera images and send them out via MPA voxl-streamer is used to receive the raw frames from voxl-uvc-server, then compress and stream the video to another computer via rtsp protocol for testing purposes, you are disconnecting the USB camera from voxl2-mini voxl-streamer keeps running, but it has no input frames to encode and send out, so it does nothing if you plug the USB camera back into voxl2-mini and restart voxl-uvc-server, the video stream resumes.

It sounds to me that the system is operating properly, but it just does not recover from unplugging the camera.

If you would like the voxl-uvc-server to recover from unplugging the camera, then you can do the following:

run voxl-uvc-server in foreground and see what happens when you unplug the USB camera (does it print any error messages) modify voxl-uvc-sever to exit if it detects camera disconnection : https://gitlab.com/voxl-public/voxl-sdk/services/voxl-uvc-server check the systemd service for voxl-uvc-server to make sure it is restarted automatically if it exits one thing to double check: if the voxl-uvc-server restarts before you plug the USB camera back in, will the voxl-uvc-server automatically detect it, or the camera needs to be plugged in before the voxl-uvc-server is restarted. (the reason why i am asking is because i don't have a usb camera to test this).

@James-Strawson This is perfect! Thank you James!

@Usama-Hamayun You should use Starling 2 for indoor mapping https://modalai.com/starling-2

Hi, were you able to find a solution I ran into the same problem.

Thanks..

@tom Thanks Tom. I already checked the link. I understand that for gpu delegate "gpu" needs to be specified in /etc/modalai/voxl-tflite-server.conf. My question is what value needs to be used in this configuration file to trigger npu deployment. According to my exploration, specifying "npu" is the same as specifying "gpu".

cpu monitoring reports there are 8 cpus for sentinel. Which of the 8 cpus are opus?

Looking forward to hearing from you.
