Serious problem. I think I may have broken some system that was in place. But here's the problem:
I have an OAK-D-POE camera, a POE switch, a Router and an older computer (2012-era).
I usually connect the computer to the router, the camera to the switch, and the swtich to the router. And since I've set the default (manual) IP on my computer, it doesn't matter what IP the camera gets served. I have been using this set-up for the past two weeks (220.127.116.11). I usually check with the depth-experimental/gen2-multiple....main.py code to check what cameras are connected and then start running my personal code.
Everything was working fine till last friday, but this morning I can't connect to the camera anymore. It simply does not recognize the connected cameras anymore. I did shut down the cameras a bit abruptly the last time I was using, but I've done this before and this hasn't been a problem. I was also playing around with the pip packages. (I was on-site with no internet access, and when I had to revert to the old depthai pacakge , 18.104.22.168, I simple copied them froma different computer and replaced them on my main machine.)
Here the weird part.
I can connect the computer to the router (over WiFi) to the switch to the camera and start using it. So it is think it isn't a hardware or connection problem. I can use the USB cameras just fine, So it is not a simple system problem as well. If this is some weird PEBKAC, has anyone else faced/fixed it? I am asking the community, as they might have faced a similar problem.
I've updated to different versions of depthai (cleared the PIP cache and re-downloaded them): No luck
I've launched a new PIP environment just to check: No luck
I've changed cables, routers and switches: No luck
Should I try it wth a new/different computer?
Bare metal Ubuntu 20.04
Depthai: 22.214.171.124, 126.96.36.199 & 188.8.131.52
Any help would be appreciated. Thanks in advance.
