Configure PAJ PET Finder 4G for Traccar

Klaus 2 days ago

@Thomas:
a flashing LED indicates that the device cannot connect to any network.
Put the SIM into a Phone:

  • check it logs into a network,
  • if yes check you can send/receive SMS.

Does your device look like this?

@Klaus,

thanks. Yes my device looks exactly like the one in the picture. I put the SIM into a phone, i was able to receive SMS, but not send ones. It booked into o2 network.

What am i doing wrong?

Thanks and best regards
Thomas

@Thomas,
I would first test the finder with a "normal" SIM card. For me, prepaid SIM cards for the 900 MHz band (D1/D2) worked best; I always had problems with o2. After inserting the SIM card, the finder needs up to 15 minutes to register on the network. The problem is that the finder goes into standby mode after 3 minutes if it's not moved. The PAJ service suggested taking the finder for a 15-minute walk and moving it around. Okay, I have a dog, so I attach the device to its collar, and it runs around the garden for 15 minutes. After 15 minutes at the latest, the blue and yellow LEDs should be constantly lit. If not, then the finder is probably defective.

Ok... is this registering 15 minutes topic only after first insert of the SIM? Or do I have this everytime I want to use the device?

Only the first time after changing the sim

Here's a quick guide to registering a PAJ Easy Finder 4G with the included Tele2 IoT SIM on the Traccar demo server:

1. Check the SIM:

Turn on the finder and place it outdoors or near a window. Wait about 2 minutes and then check the yellow LED:
If the LED is lit continuously, the SIM is activated and ready for use.

2. Change the server IP address to the Traccar demo server:

Insert a standard SIM (whose phone number you know) into the finder and send ONLY this SMS:
'IP 188.245.151.94 5013' [SET OK]
You can also optionally change the password.
IMPORTANT: Do not change the APN or other settings!

3. Reinsert the Tele2 IoT SIM card into the finder.

Now you can register your finder on the Traccar demo server.
If it doesn't work immediately, turn the finder off and then back on after a short wait.

Now you can use the finder with the PAJ SIM until they notice and block the SIM.

Hello,

Thank you very much for your efforts so far. I’ve been following this thread with great interest for some time now. I myself have PAJ Allround Finder 2.0 and Allround Finder 4G 2.0. I’m completely confused because, ever since this thread was created, it’s been about so many different PAJ trackers: Pet Finder, Allround Finder, Easy Finder, Compact Finder...

Has anyone followed up on the idea of routing the PAJ Allround Finder to a self-hosted server? As far as I understand, this fails because of the password protection of the devices?

My Finders can be controlled via text message, but they don’t send me any feedback. Only the “CQ” command works and restarts the tracker.

What confuses me is that I get absolutely no response via text message. Do the Allround Finders only respond via the serial port?

Some of you already have experience with these trackers. Have you made any progress on this?
