ZX302

Hi guys, I just installed last distribution on Windows and tried to use it with Android Traccar Client (it works! :-).
Then I tried with a Topin ZX302 but I can’t seem to make it work properly.
I tried everything listed on https://www.traccar.org/troubleshooting/ but without results.
Ports are open and server is reachable by ZX302 but It seems to me that protocol is not understood (am I missing something?):

(these are logs from Topin ZX302)

Is there anything else I could try?

Thank you in advance

Why are you using OsmAnd protocol for this device? Read this:

https://www.traccar.org/clones/

Correct port is most like likely 5023.

My fault, I did not understand that each device/protocol used a dedicated port (I were redirecting all devices to 5055 port).
Using port 5023 did the trick (even if timestamp was 1970-01-01 and GPS position was 0,0).

Thank you

What did you think we have different ports for? Why did you pick 5055?

I simply ran Traccar out if the box after watching the video on the homepage. Since port 5055 is used fot Traccar Client - and since port is configurable via SMS on the ZX302 - I thought I could use the same port. My mistake, sorry.
