  • Getting the OAK 1 POE to work with raspberry pi

Hi, i'm having trouble to connect the OAK 1 POE to a raspberry pi with no Router or DHCP server.
My setup is my raspberry pi + TP Link POE Injector + OAK 1 POE

I could make work this setup (without a dhcp server) using the pre-compiled .exe demo software on my windows machine.
However, i could not make the demo codes & examples to connet to the camera on the raspberry pi.

I followed the directions here and here (installed raspbian dependencies too)

i can ping the device that falled back to the default ip address (169.254.1.222) but cant access it with the provided examples and demo.

The raspberry is connected to a wifi network that has its own DHCP server and also via ethernet to the OAK camera.

i can not figure how to configure a static IP that works with my setup

can you guide me ?
thanks,

greffeb

    Hello greffeb , could you set static IP of RPi to eg. 169.254.1.100?
    Thanks, Erik

        Hello erik, thank for the quick response

        i have some issues configuring the raspberry to accept a static IP

        i edited the dhcpcd file
        sudo nano /etc/dhcpcd.conf

        interface eth0
        static ip_address=169.254.1.100/24
        static routers=169.254.1.1
        static domain_name_servers=169.254.1.1

        after a reboot, the eth0 interface is now disabled and i cant ping the camera

        the current setup i have is RASP ---eth-----injector--------eth--------OAK
        no connexion to another external network

        i guess this is more a raspbian issue but any help is appreciated.

          Hi,

          to exclude most of my modifications from the equation, i did a clean install of the RPi and depthAI software package

          mkdir oak
          cd oak
          sudo apt update && sudo apt dist-upgrade -y
          PATH=$PATH:/home/pi/.local/bin
          sudo curl -fL https://docs.luxonis.com/install_dependencies.sh | bash
          python3 -m pip install depthai
          git clone https://github.com/luxonis/depthai-python.git
          cd depthai-python
          cd examples
          python3 install_requirements.py
          python3 ColorCamera/rgb_preview.py

          the RPi got the IP 169.254.183.118/16
          and i'm able to ping the camera at address 169.254.1.222

          when i run the rgb_preview.py script i hear a distinct clic from the camera indicating that somethins is happening. but the test scritp return this error :

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

          any clue ?

          ok i got it to work,

          the issue was the RPi wasn't accepting a static IP like 169.254.1.100, the dhcpcd service was bootlooping and never assigning the static ip.
          With an address under 192.168.xxx.xxx, i was able to set a static IP.

          However, the camera was still set at the fallback IP 169.254.1.222
          So to make it work, i had to setup a DHCP server on the RPi to assign automatically an IP when connecting the camera. (mostly following this tutorial)

          i still get X_LINK_DEVICE_NOT_FOUND sometimes but i could launch the demo

          • erik replied to this.

            Great that you figured it out greffeb ! WRT sporadic X_LINK_DEVICE_NOT_FOUND error - do you wait some time between canceling the program and re-executing it? As OAK PoE needs about 10sec in between re-connecting to the device.
            Thanks, Erik

              Hi again !
              i think i bricked the camera by setting a static IP.
              device is not pingable and nothing shows up on the network.

              i want to factory reset the camera but the script return this error :
              skipping X_LINK_UNBOOTED device having name "<error>

              other scripts also gives this same error

              i'm currently using a laptop with the last ubuntu distro and usb3 ports

              edit ->

              again i spoke too soon this issue was resolved using this solution

              echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
              sudo udevadm control --reload-rules && sudo udevadm trigger

              sorry for the spam

              18 days later

              Guys I'm totally kinda like a noob 😂, so I've ran this command : (python3 ColorCamera/rgb_preview.py ) to test my OAK D and the following error appears to me!!!??
              [2022-03-14 20:23:55.510] [warning] skipping X_LINK_UNBOOTED device having name "<error>"
              Traceback (most recent call last):
              File "/home/pi/depthai-python/examples/ColorCamera/rgb_preview.py", line 24, in <module>
              with dai.Device(pipeline) as device:
              RuntimeError: No available devices
              So, what's this and how to solve it?,, and thanks in advance for the one who's gonna help me..

                Hello MontaserAI , I'm not 100% sure, but have you tried setting udev rules?

                echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
sudo udevadm control --reload-rules && sudo udevadm trigger

                Otherwise, I would suggest using a preconfigured RPi image.
                Thanks, Erik
