[JimXu1989]

Check if issue already exists
Google it (e.g. error xy github luxonis depthai)
Check troubleshooting in documentation.

Describe the bug
The POE version of oak-d shippped to me a few days ago, I use a PoE injector to provide power, I just follow the step asthe link below:
https://docs.luxonis.com/en/latest/pages/tutorials/getting-started-with-poe/

Both the green LEDs bright, but when I run the python demo depthai_demo.py, it shows the following error:
/usr/bin/python3.8 /home/jim/depthai/depthai_demo.py
Using depthai module from: /home/jim/.local/lib/python3.8/site-packages/depthai.cpython-38-x86_64-linux-gnu.so
Depthai version installed: 2.7.2.0
Traceback (most recent call last):
File "/home/jim/depthai/depthai_demo.py", line 114, in
device_info = conf.getDeviceInfo()
File "/home/jim/depthai/depthai_helpers/config_manager.py", line 250, in getDeviceInfo
raise RuntimeError("No DepthAI device found!")
RuntimeError: No DepthAI device found!

Process finished with exit code 1

I am confused, and don't know what to do in the next.

Hello @JimXu1989, we apologize for the inconvenience, most users have plug&play experience with the new POE models. The first thing that comes to my mind is either the firewall is blocking a port (you can disable firewall/enable ports, as described here) or your network doesn't have DHCP, so the depthai POE device sets a static IP and you need to change your IP, as described here. Have you tried both of these?
Thanks, Erik

Thanks for your reply, but I try all above, I set static IP, and I can ping the device, but the demo python script still cannot open the device, may I send it back to you to repair it?

So if you can ping the device now with a static IP, that's good. Do you still get the same error as in the original post RuntimeError: No DepthAI device found!, or is it different?
Does the IP 169.254.1.222 appears in the log when starting python3 depthai_demo.py now?

Try also having a ping 169.254.1.222 command running, and check after how much time after powering on the OAK-D-POE device (by plugging the Ethernet cable) you start getting ping replies. Check maybe a few times for a good measure.

problem solved, maybe because of my vpn connected.
