Configure PAJ PET Finder 4G for Traccar
@Mjg:
I did not touch the firmware as multiple people here were reporting bad GPS reception afterwards. I changed the sim card, adjusted the APN and I changed the host that the tracker sends its data to. In my case, the I sent the following commands through the serial port:
AT%TEST=SMS[][APN,515118,internet.t-mobile]
AT%TEST=SMS[][IP 188.245.151.94 5013]
Then I created an account at demo3.traccar.org and I registered my tracker there. The ID of the tracker is printed at the bottom of the device but you can also retrieve it through AT%TEST=START (sent through serial). A few moments later, the tracker showed online and it reported the correct position.
After I got this running, I tried sending custom commands through the traccar web UI back to the tracker, e.g.
*HQ,YYYYYYYYYY,X2,062108,1#
where YYYYYYYYYY is your device ID. This turned on the light of the GPS tracker.
If your device is working on the stock firmware, I think it should be sending the h02 protocol so you could just copy my settings. If you already flashed the other firmware or did an NVRAM reset, it might send another protocol (see https://www.traccar.org/forums/topic/configure-paj-pet-finder-4g-for-traccar/page/6/#post-109148).
@Hans, Thanks. I verified the logs on traccar server and the problem is only with GPS fix.
Any idea how to go back to the original fw?
@Mjg: Unless someone comes up with the original OTA URL that PAJ uses, we would need to extract the firmware from an unmodified device. Or you could ask PAJ politely if they want to help you out.

hi
Can you show command from Traccar debug LOG ?
I am looking for data wich is send from tracker to server
@newvol: I don't think that I can access these logs on the Traccar demo server. As I said before, my tracker sends the H02 protocol, e.g. lines starting with *HQ. This document contains some examples: https://www.traccar.org/protocol/5013-h02/GPS+Tracker+Platform+Communication+Protocol-From+Winnie+HuaSunTeK-V1.0.5-2017.pdf
Hi Hans,
What do you mean by "managed to change backend"? Changed firmware by FOTA command?
Is tracker sending correct GPS data to traccar server after this?
Do you send SMS commands or from traccar server?
