Configure PAJ PET Finder 4G for Traccar
which paj device is it?
the small black one or the one with the 2 glowing eyes?
CXZT should show status
is the tracker shown in traccar?
Can you post a pic of the details page with all transmitted data?
It's the "PAJ Allround Finder 4G", the black one without the silver line arround (that's also an Allround Finder 4G, but an LK208-4G)
The CXZT command returns nothing...
Here is the screenshot of returned data (lat and lon reduced for privacy ;) )
how did you set the apn?
I didn't set the APN, as the password is unknown.
The Tracker connects to my Traccar instance without changing the APN (with my own SIM Card)...
may i ask from which provider sim card comes?
i have a paj 4g pet here and can change all but the apn.
the apn is fixed to wsim
my emnify card does not go online
but right now it is working with my traccar server and the original paj sim card
one thing i dont understand why it the tracker sending data in text and hex?

Sure, my personal SIM Card (for testing) is from german "FONIC" with APN pinternet.interkom.de - the original SIM is an EMnify SIM Card!
The mix from text and binary messages seems normal!
then fonic is not so picky about the APN.
I am using emnify for all my trackers but the APN must be em or emnify.
In the PAJ tracker it is wsim that should be WhereEver Sim cards
Do you have a business? It is nearly impossible in germany to get an IoT/M2M Contract without a business...
2 Weeks before, i got two SIM Cards from TruPhone (Teltonika) that i can bought as a private person...
yes just google gps4pets.
We only have about 1300 trackers out in the world but we are still a young company
Oh okay, i see your homepage :)
1300 trackers sounds like a good start
just played a little around with the PAJ 4G Pet tracker.
connected it to serial TTL 2 USB converter and got a reply on the AT%TEST=START# command
Now i know the SDK type and version.
soldered usb cable to onboard USB pins. and started aboot with the firmware for the C032 4G Pet tracker.
and now i have a unlocked tracker which works with T808/huabao protocol
Finaly i get the first one to work :)
SMS Command:
Returns "SET OK"
Protocol is H02 on Port 5013
btw
Will restart the tracker
