OAK-D SR PoE not connecting to network

MPButter

Hi. I'm trying to bring up a new OAK-D SR PoE with ToF.
it is connected to a TP-Link router (running DHCP server) via a 1Gb 30W PoE injector.
the LED on the camera is on, so It appears to be powered. however, trying to connect via python or with depth_viewer app fails to find the device.

looking into the router settings, the camera is not in the clients list so it would seem network connection failed at some point, or did not start.

is there a way to debug this? see what's the connection issue?

thanks,
MP Butter

MPButter Are you on the same network? Perhaps check your router's dashboard whether there's any new DHCP lease.
Please also check Initial connection debugging docs.

Hi Erik.
I did go through the initial connection debugging docs but unfortunately didn't find anything relevant to my scenario.

I'm definitely on the same network. yes.
to clarify: I connected the camera (via the injector) wirely to the router, and looked at the router settings at 192.168.0.1. this is an isolated setup so there is no way to confuse with other networks or other DHCP servers.
there was no indication of a new lease in the router logs.

is it possible to see serial logs perhaps using the developer USB-to-M8 board?

Please try to connect to it via the m8 board. I believe it could be flashed with USB bootloader which wouldn't enable the ETH comms; resulting in issues you described.

Use device_manager; select your device, go to Danger Zone, and flash factory and select NETWORK bootloader.

Thanks,
Jaka

MPButter

thanks Jaka.
I connected the camera to my Mac via a usb-c cable and the m8 connector, and the led on the bottom is on, but device_manager does not identify any device. looks like this:

You need to put it in boot mode by holding down the boot button of the programming board (see image below) when plugging in the device. Now the device should be discovered.

Thanks,

I am facing the same problem. I purchased a new OAK-D SR PoE with ToF. I powered it up using an injector, and the other LAN cable connects to a router. My laptop also connects to the same router.

In Win10, when I type ipconfig in command prompt, it only shows my laptop IP address but does not show anything else. It seems the OAK is not connected.

HI @DavidChik , have you went through POE initial connection troubleshooting guide already? If so, what are the results of each of the test?

DavidChik

Code:

dai::Pipeline pipeline;

auto deviceInfo = dai::DeviceInfo("192.168.50.222");

dai::Device device(pipeline, deviceInfo);

If I use command prompt to check ipconfig:

I have already turned off Win10 firewall, and checked DHCP server is available.

I just wonder if MPButter has solved his problem or not

DavidChik

In Device Manager, I can find the camera. But I cannot see this in ipconfig. ipconfig only shows my laptop IP 192.168.50.77 as shown before

I tried to ping 192.168.50.170, it works

Pinging 192.168.50.170 with 32 bytes of data:

Reply from 192.168.50.170: bytes=32 time<1ms TTL=64

Ping statistics for 192.168.50.170:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 0ms, Average = 0ms

So is there anything I need to do, so I can see the camera IP in ipconfig? Or I don't need to care about ipconfig?

And what would be the minimum code for me to test the ToF (without OpenCV)?

DavidChik

Now, I can use Depthai Viewer (Python) to stream RGB. But when I go to Depth Settings to enable Depth Enabled and Apply. It said Error: CameraBoardSocket.CAM_A is not configured. Couldn't create stereo pair.

DavidChik

And then in C++. I just use one sentence:

dai::Pipeline pipeline;

If I use depthai-core-v2.27.0-win64 to build, it will say opencv_4100.dll not found, but due to our existing system, we need to keep using OpenCV 4.5.3

If I use depthai-core-v2.27.0-win32-no-opencv to build, it will say:

LNK2019: unresolved external symbol "public: __cdecl dai::Pipeline::Pipeline(void)"

LNK1120: 1 unresolved externals

DavidChik

Due to time zone difference, I just try to ask as many questions as I could 😃

1. I don't need to care about what "ipconfig" shows?

2. In Depthai Viewer, how to solve "Error: CameraBoardSocket.CAM_A is not configured. Couldn't create stereo pair" ?

3. In C++, how to solve "LNK2019: unresolved external symbol..." ?

4. Is there any minimum code for me to test the ToF (without OpenCV)?

Thank you very much.

PS: MPButter, just to say sorry for using your thread to ask my questions

jakaskerl

DavidChik 1. I don't need to care about what "ipconfig" shows?

Ipconfig shows your the network interfaces through which your PC can communicate. It will not list the device.

DavidChik 2. In Depthai Viewer, how to solve "Error: CameraBoardSocket.CAM_A is not configured. Couldn't create stereo pair" ?

AFAIK, the stereo sensors are connected to cam_b and cam_c. Cam_a is tof sensor which can't be used for stereo.

DavidChik 3. In C++, how to solve "LNK2019: unresolved external symbol..." ?

Not sure, sounds like a build issue, consider rebuilding the library. Update opencv to the latest if you can.

DavidChik 4. Is there any minimum code for me to test the ToF (without OpenCV)?

luxonis/depthai-coreblob/main/examples/ToF/tof_depth.cpp

Remove all opencv related code. Maybe just log the image frame (luxonis/depthai-coreblob/main/examples/ToF/tof_depth.cpp#L132) but not display it. That way you will know the device works.

Thanks,
Jaka

Dear Jaka and Erik,

How can I view ToF output in Depthai Viewer?

If I turn on Cam_B and Cam_C, I can see both of them (RGB 2D) in Depthai Viewer:

If I turn on Cam A only, there is nothing:

If I turn on all A, B, C, it shows Cam C only:

Please help.

DavidChik
I'd have to check if it is possible. Will report back.

Thanks,
Jaka

DavidChik

Yes please. I am worried it is hardware issue (the ToF camera is broken)?

On the other hand, in depthai/device/Device.hpp line 37 and line 67, it said Device(const Pipeline& pipeline, T usb2Mode) and Device(const Pipeline& pipeline, const DeviceInfo& devInfo, T usb2Mode) are deprecated. I wonder if this is one reason why we cannot build the C++ code?

Thanks again.

jakaskerl

DavidChik Very likely the device is not broken. I checked and you should be able to view the TOF with depthai-viewer (make sure it's the latest version).

MPButter
run pip3 install -r utilities/requirements.txt so you get the new GUI without the trial period. Make sure you update depthai via git pull --recurse-submodules and python3 examples/install_requirements.py. Then retry with both modes.
The device in USB mode should show up with 1.1 or some similar number and not have an IP. Make sure that is the case to confirm sucessful bootup.

Thanks
Jaka
