The problem is that both devices are reporting from the same IP. Because of that Traccar thinking it's the same device.
But why is it possible to make the correct distinction in 4.15
Because the logic was a bit different due to caching.
What changes should be made in version 5.9 to make the correct distinction, or can you tell me a new version that uses the same caching logic as 4.15.
thanks
I don't have an answer off the top of my head. You would have to dig into the code to see where the changes were made and how to revert them if that's what you want to do.
Thank you very much for your reply.
but now I have another question, about the problem that the device is not listed in the device list on the left side of the page, and the console has this problem
app.min.js:308 Uncaught TypeError: Cannot read properties of null (reading 'get')

(svg = Ext.clone(category.get('svg'))) || (svg = this.cloneDocument(category.get('svg')));
The above line of code reported an error.
Do you think this error is related to the fact that my device list does not display device information
Yes.
I may need you to give me some advice about the problem that the device list cannot be displayed. I don't seem to know where to start
You should use the debug version of the app to trace the root cause of the problem.
I upgraded the system to version 5.9, but found that the id value parsed by CalAmp protocol did not correspond to the id value in the previous data transmission.
For example, in my two cars A and B, when A uploads data through this IP, B also uploads data through this IP, and it is found that the id value resolved by B is the id value of A, which is not supposed to be, and there is no relationship between car A and car B
The data on the top is the data of car A, and the data on the bottom is the data of car B. The id value is the ten digits following 8305
I need your help. Thank you
