Manually set the IP and subnet of your ETH interface to make the device discoverable. docs.

Thanks,

      Thank you for your response.

      the device is discoverable now, but after running depthai_viewer while I can choose the camera, I get this error without seeing any data in the GUI.

      Error: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND, Try to connect the device to a different port.

      changing the port didn't help.

      Would you please guide me in this matter? Btw, I am using Ubuntu 22.04 on my laptop.

        worth to mention that while running this python code:

        import depthai as dai

        # Create a pipeline

        pipeline = dai.Pipeline()

        # Manually specify the camera's IP address

        device_info = dai.DeviceInfo("169.254.1.222")

        # Connect to the device

        try:

        with dai.Device(pipeline, device_info) as device:

        print("Successfully connected to the camera!")

        except Exception as e:

        print(f"Failed to connect to the camera: {e}")

        It gets failed.

        I went through updating boot loader, and did the flash factory boot loader, but not updating the boot loader. it seems like it is already updated since it's 0.0.28.

          Can you give me ifconfig output again please? The manual setting should be visible. ip route should show it as well.

          Thanks,

              Thank you.

              What I did was
              nano /etc/network/interfaces

              Added
              auto enp45s0 iface enp45s0 inet static address 169.254.1.10 netmask 255.255.0.0

              Then used this to bring it up:
              sudo ip link set enp45s0 up

              Checked it with
              ip link show enp45s0

              It showed UP and LOWER_UP.

              Verified the static IP:
              ip addr show enp45s0

              If it showed no IPv4 address, I used:
              sudo ip addr add 169.254.1.10/16 dev enp45s0

              Then I tried:
              ping 169.254.1.222

              It responded like this:
              64 bytes from 169.254.1.222: icmp_seq=1 ttl=64 time=0.123 ms
              64 bytes from 169.254.1.222: icmp_seq=2 ttl=64 time=0.456 ms

              Although the ping works, I can't see any data in the GUI after selecting the camera.

                  I think broadcast is incorrectly set. Make sure it's 169.254.255.255. Then discovery should work afaik.

                  pa526 inet 169.254.1.10 netmask 255.255.0.0 broadcast 0.0.0.0

                        Hi,

                        I tried to set the broadcast correctly
                        inet xxx.xxx.xxx.xxx netmask 255.255.0.0 broadcast 169.254.255.255

                        it still has the same issue:
                        ERROR re_viewer::depthai::depthai] Error: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND, Try to connect the device to a different port.

                        Selecting device: 19443010C126721300

                          this:
                          import depthai as dai

                          # Create a pipeline

                          pipeline = dai.Pipeline()

                          # Manually specify the camera's IP address

                          device_info = dai.DeviceInfo("169.254.1.222")

                          # Connect to the device

                          try:

                          with dai.Device(pipeline, device_info) as device:

                          print("Successfully connected to the camera!")

                          this gave me successfully connected to camera!

                          @jakaskerl
                          I tried this too
                          ros2 launch depthai_ros_driver camera.launch.py

                          [component_container-1] [INFO] [1743182047.868733852] [oak]: Starting camera.

                            And if you tried manually specifying the IP of the device for ROS example as well?
                            "[component_container-1] [INFO] [1743182047.887154780] [oak]: No ip/mxid specified, connecting to the next available device."

                            Does that work? If it works on a simple example and fails on ROS when driving multiple cameras, it's likely a power issue. Though I would check on plain python scripts as well - something like spatial yolo or something more heavy.

                            Thanks,
