Oak D pro poe connection with Raspberrypi 5B

Sarvesh · Dec 29, 2024

Should i connect oak d to the ethernet port or usb port of raspberrypi?

when i connect through ethernet, raspberrypi stops responding

jakaskerl · Dec 30, 2024

Sarvesh
USB is better since it allows more bandwidth. It's also possible to connect it to ETH but some additional configuration of network interfaces is needed.

Thanks,
Jaka

Sarvesh · Dec 31, 2024

Is it fine if i connect it through ethernet to usb converter. What are the configuration procedure i should look at?

jakaskerl · 4 Jan

Sarvesh
You mean like an ETH dongle for the RPI? Should work afaik.

Thanks,
Jaka

Sarvesh · 5 Jan

@jakaskerl Yes an eth dongle. How do i confirm if the raspberrypi is actually able to communicate with the camera and just not detecting the usb connection?

Sarvesh
ifconfig should show a new network interface with IP in the range of 169.254.x.x. Make sure the POE device has enough power ofc.

Thanks,

python3 -c "import depthai; print(depthai.Device.getAllAvailableDevices())"

One thing I'd recommend is using depthai-viewer instead of depthai-demo which is deprecated.
Also try manually specifying the IP in depthai.DeviceInfo().

Thanks,
Jaka

Sarvesh · 11 Feb

@jakaskerl in which script should i specify the IP?

jakaskerl · 12 Feb

Sarvesh
Whatever script you use to run the pipeline.

eg:

#!/usr/bin/env python3

import cv2
import depthai as dai

# Create pipeline
pipeline = dai.Pipeline()

# Define source and output
camRgb = pipeline.create(dai.node.ColorCamera)
xoutVideo = pipeline.create(dai.node.XLinkOut)

xoutVideo.setStreamName("video")

# Properties
camRgb.setBoardSocket(dai.CameraBoardSocket.CAM_A)
camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)
camRgb.setVideoSize(1920, 1080)

xoutVideo.input.setBlocking(False)
xoutVideo.input.setQueueSize(1)

# Linking
camRgb.video.link(xoutVideo.input)

device_info = dai.DeviceInfo("10.12.118.101") # set you device's IP
# Connect to device and start pipeline
with dai.Device(pipeline, deviceInfo=device_info) as device:

    video = device.getOutputQueue(name="video", maxSize=1, blocking=False)

    while True:
        videoIn = video.get()

        # Get BGR frame from NV12 encoded video frame to show with opencv
        # Visualizing the frame on slower hosts might have overhead
        cv2.imshow("video", videoIn.getCvFrame())

        if cv2.waitKey(1) == ord('q'):
            break

Thanks,
Jaka

@jakaskerl Right now, i am running

python3 -m depthai_viewer

So should i edit the init.py or main script?

BTW, when i create a new file, copy the above code and run it separately, i get the following output:

Not in viewer program. Try the script I have sent. You seem to have multiple network interfaces which interfere with eachother. Manually specifying IP as in the script i sent above should solve the issues.

Thanks,
Jaka

The above is the script that i copied from your above suggestion and changed the ip to 169.254.1.222. But i get the above error. what do you think i did wrong?

jakaskerl · 14 Feb

Sarvesh
You seem to be using an older depthai version. The constructor args for pipeline and deviceInfo were added in 2.26 I think. Please update to 2.29.0

Thanks,
Jaka

@jakaskerl
after i upgraded the depthai version and ran the script , I am getting the following error

Update:

I also updated the bootloader version. But still showing same error:

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

jakaskerl · 17 Feb

Sarvesh
Ok, now it does sound like a power issue. Please check you have enough power delivery through the POE switch.

Thanks,
Jaka

Sarvesh · 17 Feb

How do I check if it's receiving power? Is their a script to read the current and voltage recieved?

jakaskerl · 18 Feb

Sarvesh
Unfortunately no. What are you using to power on the device? Make sure it supports POE 802.3af.

Thanks,
Jaka

Sarvesh · 18 Feb

The green cable is going to the raspberrypi

What is the difference between 802.3at vs 802.3af?
