OAK D PoE devices listed multiple times, unable to connect to some

tekt

I have a network with 3 OAK D PoE devices and a server. When I use depthai_demo.py, it shows output like:

Available devices: [0] 192.168.1.4 [X_LINK_BOOTLOADER] [1] 192.168.1.3 [X_LINK_BOOTLOADER] [2] 192.168.1.2 [X_LINK_BOOTLOADER] [3] 192.168.1.3 [X_LINK_BOOTLOADER] [4] 192.168.1.2 [X_LINK_BOOTLOADER] [5] 192.168.1.4 [X_LINK_BOOTLOADER]

It seems odd that some of the devices are showing up multiple times.

I'm able to connect to two of those devices by IP (*.3 and .4), but connections fail to the third one (.2). It produces errors like this:

File "C:\chhs\depthai\depthai_demo.py", line 560, in run self.instance.run_all(self.conf) File "C:\chhs\depthai\depthai_demo.py", line 62, in run_all self.setup(conf) File "C:\chhs\depthai\depthai_demo.py", line 135, in setup self._device = dai.Device(self._pm.pipeline.getOpenVINOVersion(), self._deviceInfo, usb2Mode=self._conf.args.usbSpeed == "usb2") Failed to connect to device, error message: X_LINK_COMMUNICATION_NOT_OPEN

Anyone have any ideas how to fix it?

Hi tekt ,
I believe the reason for duplicate devices found was due to multiple interfaces connected (ETH + WIFI), but we have fixed this issue in depthai 2.17.0.0 (latest). Could you try updating your depthai version and trying agian (in depthai repo run git pull and python3 install_requirements.py)?

Thanks, Erik

erik I'm now only seeing each device once, and they're showing some sort of hex ids instead of ips.
But it's still unable to connect to one of them.

Hi tekt , cross-check the OAK POE troubleshooting section? As it might be some issue from there.
THanks, Erik

erik I've tried to change the IP settings on the device, but device_manager is unable to connect to it. It seems to be able to query its state and configuration, but when I try to flash the configuration, it fails (see below).

I don't currently have physical access to the device, but it's starting to seem like that might be necessary to fix this, with a direct usb connection as described here:
