  • No depth ai devices found - wsl2 - ping works

kneave Thanks for quick follow ups on my queries. Appreciate your time.

I have made .wslconfig file like suggested and added mirrored setting.

Note: .wslconfig.txt is what i made in the directory suggested. Is that fine?

When I call sudo wget -qO- https://docs.luxonis.com/install_depthai.sh | bash and I open demo viewer , it still didnt find any depth ai devices.

Note:

  1. Im still able to ping the sensor with the same ip in windows and linux(wsl2).
  2. I also reopened wsl and then run sudo wget -qO- https://docs.luxonis.com/install_depthai.sh | bash. But it still doesnt work

Any suggestions?

    I just checked my laptop and it's .wslconfig without a file extension so it's worth being exact.

    If you see the same IP addresses and still can't connect though then I'll have to leave that to the experts at Luxonis. I've never used a POE device, I just jumped in as I have experience with WSL networking.

      Did you create wslconfig or .wslconfig as the . at the front makes a big difference. Please share the contents of the file and the new ip/if config outputs too, if you can confirm you've rebooted too please as WSL will need to restart I think.

        Ive used .wslconfig

        the contents are:

        [wsl2]

        networkingMode=mirrored

        I did close the terminal and reopened wsl. That reboots wsl right?

          If you close the terminal it carries on running in the background, if you open a Windows terminal you should be able to shut it down using wsl --shutdown though, a reboot would definitely do it at worst. As I understand it, WSL is running on some kind of VM type thing in Hyper-V but I don't know the specifics.

            Hi @SarveshRathi
            How about the other side (the HyperV FW)? https://learn.microsoft.com/en-us/windows/security/operating-system-security/network-security/windows-firewall/hyper-v-firewall

            Make sure to also check the route tables if the traffic gets routed correctly. When not specifying the device IP when calling dai.Device() the library will send a broadcast which will not be received if there are issues with the subnet. When providing IP, this will be skipped and should work outside subnets iirc.

              I think that worked. Now I am getting a new error message.

              RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

                  This usually signifies a power issue, could you check you are getting enough power? I found I have this issue when using injector instead of POE switch.

                  You might learn more by inspecting the network traffic to see if it gets routed correctly.

                      Thanks jakaskerl

                      Ok. So the issue is resolved.

                      I had to add the ip in same subnet.

                      sudo ip addr add 192.168.50.X/24 dev eth0

                      where x can be any number

                      How do I inspect the network traffic? Since right now I can connect the camera through the injector, but as soon as I move it crashes.

                          Hi @SarveshRathi
                          Great!

                          SarveshRathi How do I inspect the network traffic?

                          I usually use wireshark to check the traffic.

                          SarveshRathi Since right now I can connect the camera through the injector, but as soon as I move it crashes.

                          What do you mean by as soon as I move it? Have you tried using a switch instead?

                          Thanks,

                                How does this look?

                                This is the current output

                                RuntimeError: Failed to connect to device, error message: X_LINK_DEVICE_NOT_FOUND

                                  Hi @SarveshRathi
                                  This looks ok as long as the switch is rated correctly (https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/powering_poe_devices/#poe-switch-or-injector). You don't need the switch inbetween since it does nothing essentially. My suggestion was to use a POE switch, which can be used directly - without the POE injector to power the camera.

                                  I still don't understand what you mean by "as soon as I move it crashes". Do you suspect a bad contact issue?

                                  Thanks,

                                    jakaskerl The Se 3005 switch does not support POE. So I have to use the midspan injector which is rated Single port 95 Watt/55V DC/1.73A, 802.3at. This should work right?

                                    Im not sure what is the issue exactly, but right now it finds the device then returns RuntimeError: Failed to connect to device, error message: X_LINK_DEVICE_NOT_FOUND

                                      Hi @SarveshRathi
                                      As long as you can see the lights on the ETH port, the layer 2 network devices should have no problem correctly routing the traffic, so I'll assume the issue is still on the PC.

                                      Does pinging work in this setup? Check the traffic or tracert function to see if correct routes are used.

                                      Thanks,
                                      Jaka

                                        jakaskerl I dont see a light at ETH port, but the POE and power indications are on. Ping works.

                                        Traceroute shows 0.2ms 0.003ms 0.003ms

                                            dai.Device(pipeline, deviceInfo=dai.DeviceInfo("IP of your device"), maxUsbSpeed=dai.UsbSpeed.SUPER)

                                            And you are using the IP to connect to the device? I don't see why this wouldn't work then, unless there are firewall issues.
