Hi, anyone can help please, I have these trackers CJ780 that uses h02 protocol, I have using 4.12 version before, Now I have upgrade to 5.12, and I having a lot of Unknow Devices coming in the logs.

the first line has this ID: 2478010489 - But this ID is wrong, because the correct ID is 7801048919

If it was registered with 7801048919, why it keeps trying to connect with wrong ids ?

So what happens when you add id: 2478010489

I Dot not need to add, because it is already on the system with the original ID, if I add it, It will duplicate the device, and a few seconds later, this wrong ID will disconnect by itself

Why would it duplicate the device when rhe id is not the same?

Because in the logs I can see that is the same device, for example: 7801048919 is the real ID from the device, but sometimes the tracker keeps trying to connect with another ID , like 2478010489, and before (traccar version 4.12) it did not happened. I think it was something changed on the h02 protocol.

I don't think there were any changes to the way ids are decoded. Do you have a protocol documentation?
