  • No device found using getFirstAvailableDevice() OAK-D POE

Hello
When I try to connect to my OAK-D POE device with the dai.DeviceBootloader.getFirstAvailableDevice(), the function returns False DeviceInfo(name=, mxid=, X_LINK_ANY_STATE, X_LINK_ANY_PROTOCOL, X_LINK_ANY_PLATFORM, X_LINK_SUCCESS)

When I try to connect to the camera using the device_manager.py in the depthai-python/utilities repository from github, no device comes up, but i can find it when using "specify ip", and I can also ping to it.

I have flashed the latest version of the bootloader to the camera via "specify ip".
What can I do in order to also find the device using "getFirstAvailableDevice()"?

    Hi Jonas_declercq !
    I believe the device is on different LAN then your computer - so to find it automatically (getAllDevices) you would need to have both camera and computer on the same LAN. There are various ways to achieve that, depending on how your network is configured. Some useful POE docs here.
    Thanks, Erik

        Hello erik

        I manually configured my network with settings:
        ip address: 169.254.1.10
        netmask 255.255.0.0
        on ubuntu 22.04 but i keep getting the same error.
        I reïnstalled the depthai package and recloned the git repo without success.

            Hi Jonas_declercq , have you gone through all the POE troubleshooting docs? If you flashed a static IP to the camera you need to be in the same network, as now it doesn't have the default ip anymore (169.254.1.222).
            Thanks, Erik

                Hi, erik

                I have gone through the troubleshoot pages a few times and have not flashed an ip to the camera.
                I can find it with the specify ip option in the disc manager and i can ping to it.
                Also when i use the depthai.DeviceInfo("169.254.1.222") i can get it running.
                The problem is when i want to flash pipelines to use in standalone mode.
                Is there a way to get the same info getfirstAvailableDevice()returns with just the ip address?

                Thank you

                    Hi Jonas_declercq ,
                    Are you perhaps connected via multiple interfaces (eg wifi and ethernet)? Could you share the full log of ipconfig/ifconfig?
                    Thanks, Erik

                        I got a bit same kind of trouble with OAK-d lite:

                        RuntimeError Traceback (most recent call last)
                        Cell In [5], line 105

                        104 # Connect to device and start pipeline
                        --> 105 with dai.Device(pipeline) as device:
                        106
                        107 # Output queues will be used to get the rgb frames and nn data from the outputs defined above
                        108 previewQueue = device.getOutputQueue(name="rgb", maxSize=4, blocking=False)
                        109 detectionNNQueue = device.getOutputQueue(name="detections", maxSize=4, blocking=False)

                        RuntimeError: No available devices

                        Demo works but i cant reach it with sample code.

                          Hi akirs3 ,what version of depthai are you using? Are you running multiple depthai scripts that connect to the device? Can you try finding the device via Device Manager?
                          Thanks, Erik

                            erik Hi Eric, sorry for my late response.
                            I am using the latest version of depthai and ive reïnstalled it a few times to try again.

                                Jonas_declercq sorry, I wanted to tag @akirs3 , as he commented on this thread as well.
                                WRT your issue - could you disable other interfaces (eg turn off wifi)? We have noticed this was the culprit of the erorrs many times (docs here).
                                Thanks, Erik

                                    erik I disabled the other interfaces and reconnected the camera but without success. I get the error message "No available depthAI device found"
