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](https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/getting-started-with-poe.html) and [here](https://docs.luxonis.com/projects/api/en/latest/install/) (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"#p2982 , could you set static IP of RPi to eg. `169.254.1.100`? Thanks, Erik

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!!!??

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,

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 ?

greffeb

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

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

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
