Configure PAJ PET Finder 4G for Traccar

possible in principle.
Only:
I also get the password error with other variants. For example:

• APN,iot.1nce.net,,#
• admin123456 12345678

Also:

• the command ‘format’ should set everything to default, including the password
  G123456# -> replies with current location

gprsset# -> No Response

have you tried

FACTTORY
RESET

with or without # ad the end to reset to factory defaults and the password to 123456

or first

RST

and then directly after the tracker is restarted

FORMAT

try 999999 for password

G123478# -> also replies with current location....so maybe the six digits do not matter

In Sequenz:
RST -> No Response
FORMAT - > SET OK
APN,123456,iot.1nce.net -> Password Error

APN,999999,iot.1nce.net -> Password Error

Was sagt er wenn du RCONF sendest?

I have the PAJ Model "Allround Finder 4G" with the same behaviour...

I removed the glue from the sim card slot and replaced the original EMnify SIM Card.

Also RCONF or RCONF# returns nothing.

On the magnetic charger port there is an serial interface, but it returns only "Bye Bye Bootloader" on Boot.

try to send this via serial:

AT%TEST=START#

Still nothing, but this boot the system glitches and show a little more information

ok thats a SIMCOM A7670 LTE Device in the LLSE version.

thatv piece of software is pretty old, never have seen a sdk version prior to 2023 before and this is from april 2022

you can try a native SIMCOM A7670 command.

Okay, this one is a LK208 4G Model, i will try the SMS commands as soon as i have a spare nano sim card ^^
