One of the most popular trackers are the Xexun 102 and 103 trackers. There’s imitation devices being sold so be careful. I have never seen a product where the documentation is so bad, the amount of documentation versions is so huge (each saying something different) and where there is NOT 1 place on the internet that tells you how it works. There’s a forum with a lot of information: 1 THREAD with 2,500 messages !??
I would still buy a TK-102 or TK-103 if I needed another one ;-)
Xexun TK 102 This is a ‘pocket’ tracker. Very small, with battery, built in antennas.
Xexun TK 103 More for a fixed mount in a car. Has a lot of extras like an external microphone, external antennas for GPS and Cell, ability to close switches remotely etc.
How to setup
So here’s an overview of how I configured my TK-103. These instructions will most likely also work for the Xexun TK-102. Free tracking service used: Orange GPS Trace. First register yourself.
Now you have to setup your Tracking device by sending SMS (text) messages to it. Make sure it has a valid SIM card that supports DATA. (in my case I use Simyo as it charges data by the Kb – it costs me approx 10 euro / year but doesn’t work outside of the Netherlands)
begin123456 (clears configuration of tracker)
> BEGIN ok
password123456XXXXXX (if you want to change 123456 to something else)
> PASSWORD ok
adminXXXXXX0611223344 (your cellphone number – so it knows that commands send by your phone are valid)
> ADMIN ok
apnXXXXXXbasicinternet (APN of your provider)
> APN ok
adminipXXXXXX220.127.116.11 20157 (IP and PORT number of GPS-TRACE tracking service)
> ADMINIP ok
t030s***nXXXXXX (t030 = every 30 seconds, s***n = unlimited messages, replace *** with number of messages it may send)
> T030S***N ok
webXXXXXX (enable sending of location via IP)
> NOTN ok!
nobatteryXXXXXX (optional: to disable low battery messages – trust me, you want this!)
> no response
tlimitXXXXXX 200 (only report location when moved >200 meters)
> TLIMIT ok!
Next, login to the Orange GPS Trace service and add your tracker as a device. See screenshot below:
To find the IMEI of your device remotely you can use this website: http://id.wialon.net/
It does require you to change the adminip but it’s easy to change it back to the settings above.
When everything works you can see your location on a Google Map using the following URL
Save your device and start moving. You should see your device appear on the Map at some point. Gps-trace also has a forum. Now you can start using my Homeseer script that uses the Orange Gps Trace service to put your location in Homeseer.
