Awesome. Thanks!

After updating depthai to 2.17.0.0, I'm getting an error in one of my scripts:
AttributeError: 'depthai.node.ObjectTracker' object has no attribute 'setTrackerIdAssigmentPolicy'
But as far as I can tell, that method still exists:
https://github.com/luxonis/depthai-core/blob/355c6712190a9e8eb8490355a6e7cb29face4b16/src/pipeline/node/ObjectTracker.cpp#L32

Any idea what changed?

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:
https://docs.luxonis.com/projects/api/en/latest/components/bootloader/#boot-switches

The error:

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.

As part of a long-term art installation, I'm using 3 OAK-D PoE devices to track the positions of people standing in front of it.

My current approach is based on the spatial object tracker with RGB example (with mobilenet ssd). It seems like objects are often lost but rarely removed. I'm seeing large numbers of LOST statuses (including repetitions for the same id) but they mostly (but not entirely) just stay in that state indefinitely.

First, is there a better approach for this kind of thing? The data I need is just a distance from the device for each tracked person, with ids attached so I can keep track of how long each person has been within range.

Second, if object tracker / mobilenet-ssd is the best option, can I configure how long it keeps LOST objects before marked them as REMOVED, and some sort of threshold of when it treats an object as NEW vs switching an existing from LOST to TRACKED?
