Device already occupied

RexMello

I recently got an OAK-4-S and its been running fine. Sometimes however the issue I face time to time is that my camera stops working and when I try to run OAK-Viewer I get an error saying device is already in use while none of my code is running. I tried restarting the PC but that doesn't help so I replug the camera and that fixes it most of the time. Any help would be appreciated

Hmm, perhaps another instance of OAK-viewer is open? It's also possible that a preinstalled app is running on the device.

Check with oakctl app list.

Thanks for reaching out, I tried that and also
oakctl device info

Both commands give me an error saying
"Comms error: Failed to wait for response"

Could the error be in hardware?

Can you update the OS and oakctl first? https://docs.luxonis.com/software-v3/sw-stack/luxonis-os/

The issue we're facing currently is that all oakctl commands give that failed to wait for response error. I'll try reconnecting it or with USB and update the OS. After reconnecting it works sometimes

Hey RexMello
Do it via the OTA update path - "OS Update". LMK if you have any further issues. oakctl (provided it's the latest version) should work then.

Thanks,

In OS Update I need to ssh into the device IP. On the guide it says I don't need a password. However when I try doing ssh into the camera, it asks for a password. I tried "luxonis", "admin" and "root" and get permission denied error

root@10.0.10.93's password:

Permission denied, please try again.

root@10.0.10.93's password:

I tried with sudo permission too but that doesn't help either. What should I do?
