Configure PAJ PET Finder 4G for Traccar

I have a PAJ PET Finder 4G.

I was able to change the SIM card successfully. The device seems to connect to the network successfully with the new card.

However, I have not yet been able to find the appropriate SMS commands to connect the device to the Traccar server.
(I have found SMS commands that should work for some PAJ devices (PAJ Power Finder, Easy Finder 2.0, Allround Finder, Motorcycle Finder). However, my device either does not respond to them at all or responds with ‘Invalid Command’.

Does anyone have any idea how to configure the PAJ PET Finder 4G?

Best regards

Which app does it use by default and what are the sms commands that you are sending ?

which commands have you tried?
I import a lot GPS Trackers and have some good connections to the manufacturers.
Which protocoll is the tracker using?

can you try this commands:

CXZT
STATUS#
VERSION#

looks like an uniguard v43.

please try this:

Check device setup
at^param=?

Setup APN
at^apn=APN,user name, password,
E.g. at^apn=Safaricom,,,

Restart device
at^reboot=1

if is a reachfar v43 try this:

pw,123456,center,YOURNUMBER#
apn,apndata,username,password,network code#

Commands (and responses) I tried so far:

begin123456 -> No Response
adminip123456 ServerFQD ServerPort -> Invalid Command
adminip123456 ServerIP ServerPort -> Invalid Command
IP1,ServerIP,ServerPort -> Invalid Command
*routetrack*99* -> No Response
status -> No Response
imei123456 -> No Response
adminip123456 ServerFQD:ServerPort -> Invalid Command

So far i do not know so much about the device.

Default App is a proprietary PAJ-App/Webservice: https://www.paj-gps.co.uk/finder-portal-instructions/ (i have not used it so far).

It looks like different PAJ devices use different protocols:

• https://www.traccar.org/forums/topic/paj-gps-professional-finder-20/

I have at least one working commend:

G123456#
(123456=default password)

replys with current location

what about

#STATUS
adminip123456 ServerFQD ServerPort

see the space in adminip command between ServerFQDand ServerPort

123456,STATUS -> No Response
APN# -> Invalid Command
STATUS# -> No Response
format -> SET OK
APN,iot.1nce.net,, -> Password Error
APN123456,iot.1nce.net,, -> Invalid Command
admin123456 12345678 -> Password Error (12345678=Phone Number)
password123456 654321 -> Password Error
admin 12345678 -> Invalid Command (12345678=Phone Number)
APN,iot.1nce.net,,# -> Password Error
SERVER,1,ServerFQD,ServerPort,0# -> No Response
#STATUS -> No Response

adminip123456 ServerFQD ServerPort
see the space in adminip command between ServerFQDand ServerPort -> No Response

try
APN,123456,iot.1nce.net

stop,180 -> No Response
APN,123456,iot.1nce.net -> Password Error

ok than APN,passworfd,apn is the right command but the password was changed from 123456 to another one
