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.
@Hans Acker
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,
can anyone tell me what PAJ GPS tracker should i use, to be able to send at commands over USB port (without UART).
Thanx
I have a PAJ Compact Finder 4G.
I inserted my own SIM card (Vodafone CallYa) and send this SMS:
format -> SET OK
APN515118 web.vodafone.de -> APN OK
IP 188.245.151.94 5013 -> SET OK
But how do I get the identifier that the device sends to the Traccar demo server?
With the PAJ-ID number or the device IMEI, the tracker is displayed as offline.
You should check your traccar server log what the device actually sends.
@Klaus add 0 before ID
@Track-trace:
- Where can I find the server logs?
- How can logs be assigned to my account if the device isn't recognized?
@Mjg:
Unfortunately, that doesn't help either.
The PAJ-ID is '9093001423' - don't work: '9093001423' & '019093001423' & '09093001423'
@Track-trace & Mjg:
Sorry, my mistake was: I had set the IP address of demo server 3 in the device, but then I entered the device on demo server 1.
Now I've registered the device with the PAJ-ID on demo server 3, and it was immediately shown as online.
Here's a short guide on how to display a PAJ Finder on the Traccar demo server:
I tested it with these devices:
- Compact Finder 4G - (https://www.ebay.de/itm/206298275868)
- Easy Finder 4G - (https://www.ebay.de/itm/188422478583)
Two devices are being sold for the price of one.
With the Compact Finder, the SIM card can be replaced without opening the device.
With the Easy Finder, you have to unscrew the device.
1. Download and install the Traccar Manager app
Important: Only after the first launch of the app can you change the default server setting at the top center: "Server: demo.tracker.org".
Set the appropriate server there. Server overview
Then register.
2. If the device contains an activated Movistar SIM, it can continue to be used.
2.1 Check if the SIM is activated:
Turn on the finder and place it outside or near a window and wait approximately 2 minutes and then check the yellow LED:
- still flashing, the SIM is probably not yet activated and you will need your own SIM.
- constantly lit, the SIM is activated and you can try using it.
2.2 Check if the activated SIM is from Movistar:
The finders contain SIM from various providers.
Remove the SIM and note how it was inserted.
- If the SIM has the imprint "M2M" and three lines with a 5-digit number each, followed by a 4-digit number,
then it is from Movistar and can send and receive SMS. - Otherwise, you will need your own SIM.
2.3 Determine the phone number of the activated Movistar SIM:
You will need two smartphones: Insert the SIM into one and send an SMS with any content to your second smartphone:
- If the SMS does not arrive, you will need your own SIM.
- If the SMS arrives on your second smartphone, you will have the phone number of the SIM and can create a contact for this number called "PAJ-Finder".
3. If you are using your own SIM, create a contact for its phone number called "PAJ-Finder".
Insert the activated Movistar SIM or your own SIM into the finder, switch it on, and wait until GSM reception is established.
Then, from your smartphone, send the following SMS to the previously created contact "PAJ-Finder":
- Reset to factory settings: '
format' [SET OK] - Change password: '
password515118 654321' [password ok] - Set the IP address of the demo server: '
IP 188.245.151.94 5013' [SET OK]
Caution:
- The text for the SMS is enclosed in quotation marks '
sms text'. Send it without the quotation marks. - The reply to the SMS is enclosed in square brackets [ ].
- Always wait for the reply before sending the next SMS.
- The default password is 515118; the new one must consist of 6 digits.
- The IP address of the demo server you selected earlier (see 1.) can be found in the Server Overview
- The finders switch to standby mode after approximately 3 minutes of inactivity, but can be woken up again by sending an SMS with '
G123456#'.
4. Now you can register your finder in the app:
To do this, press '+' in the upper right corner: any name you like, Identifier is the finder ID, i.e., 909...
The finder should be displayed shortly afterward.
Addendum:
ONLY if you are using your own SIM card its needs to configure the APN via SMS:
e.g. 'APN654321 web.vodafone.de' [APN OK]
See APN List by Country and Carrier
!!! DON'T change the APN of Movistar SIM cards !!!
Hi, I have a PAJ Easy Finder 4G with a thingsmobile IOT SIM Card. The SIM Card is activated, and has no PIN activated.
I have put it into the device, and if I power on, the yellow LED keeps blinking.
No SMS command worked so far. I tried "format", "APN515118 TM" - no reaction.
Do you have any tipps for me?
Thank you in advance
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?
