Logic for Unknown device

Hi Anton,
Noticed some weird location points of one device. When I review the log files, I noticed all weird location points were from an "unknown device".
Is there any special logic to attach an unknown device to an existing one? Thanks.

Logs? Locations from unknown devices are not stored anywhere.

4XXXXXX595 - registered device
5XXXXXX705 - Unknown device

The issue is that it's all coming from the same IP address, so for server there is no way to distinguish.

Never mind... looks like IP is different.

Hi Anton,

Is it related to this line,

https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/handler/FilterHandler.java#L189

line 189            message.append(Context.getIdentityManager().getById(position.getDeviceId()).getUniqueId());

When it implicitly get the UniqueId, the application set the uniqueId as well (this.uniqueId = uniqueId)?

Thanks,

Where do you see this part?

No, I haven't found it directly.
Might be somewhere in the "Device.java"? If the uniqueId is null, not sure how the Construction method works. Thanks.
