No depth ai devices found - wsl2 - ping works

SarveshRathi · Apr 4, 2024

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

SarveshRathi Failed to find device after booting

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,
Jaka

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,
Jaka

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,
Jaka

SarveshRathi · Apr 11, 2024

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

SarveshRathi · Apr 15, 2024

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

jakaskerl 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.

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.

Thanks,
Jaka

jakaskerl Where do I update the IP in depthai_demo.py script?

jakaskerl · Apr 17, 2024

Hi @SarveshRathi
I'd suggest against using depthai_demo until you get the connection working, but luxonis/depthaiblob/main/depthai_demo.py#L210 has the deviceInfo part which you can hardcode with the IP.

Thanks,
Jaka

SarveshRathi · Apr 18, 2024

jakaskerl I think the midspan injector meets the rating requirements. So i feel it shouldnt hamper the connectivity issues. Does it boil down to firewall based on all the debugging done above? if yes, how do you suggest I start debugging?

jakaskerl · Apr 18, 2024

Hi @SarveshRathi
Does it work when you explicitly set the IP?

Thanks,
Jaka

SarveshRathi · Apr 25, 2024

jakaskerl No it does not.

Based on our discussion,

Could you please summarize steps in order that I should check?

Kkneave · Apr 25, 2024

How about trying with a super simple script like this one that reads the IMU version? Just replace the line in it that Jaka provided above to set the IP address for the device and see what it comes back with.

SarveshRathi · Apr 26, 2024

kneave Thanks Kneave. I will try that and get back to you shortly. On the other hand, does me using a Tplink ethernet to usb converter to connect to camera make any difference? I can get ip and subnet from control panel and it says its in the dhcp network but dont find it when using ip addr show.

Kkneave · Apr 26, 2024

Can you do ifconfig in WSL and ipconfig in Powershell please?
