ZX612 Mini chinese GPS

Anton Tananaev6 years ago

Port 5055 is almost definitely a wrong one. It's only for Traccar Client. GPS trackers don't use it.

Then which one should I use?

Sandesh,
The right port number is 5023. I found two main issues with ZX612. The first is that it takes time to fix GPS position. The second is that when it looses signal, it returns lat 0.00 and lon 0.00 instead of the last valid position.

So its unreliable

If I would suggest, take a TK102B.

I received a protocol information from chinese guys. It can fill some grey areas which remained after reverse engineering.
But the main problem of this device - it resets the server address and port to defaults after loosing connection to manually programmed settings (for example I started the server on my PC and turned it off for 5 minutes)

Hi Robert,
I own TOPIN D3 which has ZX302.

I think, it is preety much close to ZX612 (or the same?).
And, yes, it works with traccar (version 3.15).

For now, it is not possible to send command from traccar (f.e. PeriodicReporting (I dont mean via SMS)). For Tk103b it is possible. Maybe via custom command it is possible, but I have not try it yet.

But these tracker has strange behavior and limitations (it is not traccar problem):

  • I can't change interval (for sending GPS data to my server via GPRS). It is set to 3 minutes. When I send SMS "TIME#15", it reply "TIME#15", but the interval is still 3 minutes.

  • It is not possible to set GPRS to economic mode (less GPRS traffic). I mean, when there is no GPS position change for 10 minutes, GPRS disconnect and connect again when alarm being triggered or GPS position changes.
    For example: http://gpsrf.ru/download/usermanual_tk103b_eng.pdf
    point: 6.34 Less GPRS traffic

  • sometimes it give me position 0,0

  • sometimes it change sending data to default server (www.365gps.com).
