These all look ok.

Either POE injector is not capable of supplying stable power or the connection drop is too long. First case, try to swap out the injector for a switch.
Second:

  • test if this works: ping -I eth1 169.254.1.222
  • increase watchdog timeout when running your scriptDEPTHAI_WATCHDOG_INITIAL_DELAY=60000 DEPTHAI_BOOTUP_TIMEOUT=60000 python3 script.py

    1)

    I dont have a poe switch. which switch would you recommend I buy in India?

    2)
    DEPTHAI_WATCHDOG_INITIAL_DELAY=60000 DEPTHAI_BOOTUP_TIMEOUT=60000 python3 manual_ip_program.py

      Don't know what is available in India specifically, but you usually can't go wrong with popular choices such as TPlink and netgear..

      I assume ping -I eth1 169.254.1.222 works

      Thanks,

        @jakaskerl Thank you.

        What should be the rating of the switch? I'm assuming a 5V 600 mA would be less right?

        Yes. The ping works.

          Specifically look for 802.3af standard or better (802.3at).

          Thanks,

            @jakaskerl i tried the above poe switch, but it still gave the same error.

            I also tried another dongle just in case but it still did not work.

            What could be the root cause?

              I connected the device to MacBook air where I have also installed Ubuntu and ran the calibration dump code like you recommended. Following picture shows the output:

                Hi Sarvesh
                I took another look at your initial post. Are you still using the ETH to USB dongle? If that is the case could you take a picture of it - it is probably the cause of the issue. I'd like to try to reproduce the issue with a similar dongle to check what can be done.

                If that is not the case, I am out of ideas as far as SW related issues go so I suggest we replace your device.

                Thanks,

                  @jakaskerl I tried using three different dangles. It worked with neither.

                    Hi Sarvesh
                    Tested myself on a RPI5B with the USBA-ETH dongle and found no issues even with an injector. Leaves me no option but to attribute it to a HW issue.

                    Please write to support@luxonis.com so we can replace your device.
