Traccar is a nice open source server. www.traccar.org/download/ I'm not sure it its the same as described in video though.

[@rkan2]

All of these chinese devices usually support one of the protocols that Traccar supports. I highly recommend Traccar!

[@harvyrodriguez7786]

This is a great video thanks. I got one of these and I connected it to the battery but it's not sending me an sms back, do you happen to know what I am doing wrong? I have checked it and both lights go on when I insert the sim card and I have also tested it in a cellphone but it doesn't send me the sms back when I'm trying to set the configuration

Thanks for this analysis. I have been interested in one of these for some time and eagerly look forward to seeing you succeed in getting it working properly.

I would also like to see that tracking server. Is there an alternative firmware maybe?

[@voltlog]

I don't think there is any chance for alternative firmware as these Chinese SOC are usually closed source.

[@spokehedz]

@@voltlog Ah, darn shame. Just have to watch to be sure that no weird SMS messages get sent to weird numbers then... I don't know how you could know if it was sending weird stuff out over the data connection...

No need for an alternative firmware, you just reconfigure it to send the data your/any Traccar server.

[@t.wadegonder1288]

I've spent two days trying to get it to work with a web tracking application, to no avail here in Colombia. Putting the sim in and changing some parameters was simple enough. I'm in Colombia, and have a 4G sim that is supposed to do 3G too. I don't know about 2G Some say the tracker only works with 2G, but that seems a bit silly for a "modern" design. Anyways, the SMS messages come in and get sent back to the Admin cell phone. I changed all kinds of settings trying to "connect" with Yuntrack and Traccar. I'm not sure if the CJ720 is supposed to talk with the local carrier MMS or internet server. I downloaded the traccar client app to an Android phone, for testing of the phone's settings, and could get a location, but not any tracks when I walked around the block. Iffy stuff at best.

[@ronniepirtlejr2606]

You should test the circuitry out to see if it will cut out and quit charging the Lipo at the right voltage 4.2V. Max.... that way it doesn't go boom!

[@mikefooyc5415]

For your problems with gpscj site. I've had luck with NOT messing about with server settings. Other than the basic set up. I changed the apn my telco and changed the update time in seconds(1-180). I set mine to 180 seconds, it'll upload its own location every 2 minutes. Saving battery and data. It doesn't matter really; once engine is started and device is in active mode, the unit uploads data every 5-15 seconds. In disarmed mode, you'll won't be getting any vibration alarms. Only power cut. I don't have high hopes for that small lipo cell though, it might just fail outright when you needed it most. So hide it well. Chances are they won't be driving without a battery anyways. I use the relay to drive my keyless start kit. Since the rfid ring takes around 20ma as it pulses for the presence for key. It does this all day and all night, so this handy relay helps.

[@stacyjohnson1064]

Thanks for the instructions. Got it up and running in the UK on a giffgaff sim card. Works great, I wired the relay to the horn so if I am near to my car but can't find it exactly, I sms the command and switch on the car horn. Server is working on mine too. Mine is in the car interior behind the dash and the signal is fine.

[@misterg4548]

How does the gps antenna work if installed under the (metal) hood of the car?

[@111chicane]

It doesn't work at all, unless you open the hood. However, when it can't get a GPS lock, it will determine the position by triangulation of the cell signal, which, of course is far from precise.

[@voltlog]

There are places in a car where you could install this and still get a signal

[@MaxMax-dq1lu]

I was wondering about that... Would b good if u test that..!

[@Nova-ne1il]

D Stanoev unless you attach it to the wheel sensor sys....... Hehehehe you are absolutely that ex to track haha then sell the information to people on the dark web for quick cash......... It's that simple ... If you get your oil changed or your car serviced a slip of less than 100 bucks and your everything is available. Get used to it or service your car yourself. .. and under a hood ........ Just snip the ground . And it's now a a receiver. You won't get that.

[@grahambrown5874]

This is a very useful and detailed video. I have bought several gps trackers and now have one of these to test. I want something I can attach to my motorbikes that is reliable and can cut the fuel. But where as the others need to be hidden and that mean the satellite gps function is less reliable, with this device I can have it exposed because it looks like a relay. I glad you dissembled the unit as it shows there is no physical relay but a MOSFET to switch the power to the fuel pump etc. It does draw 60mA in standby, so the bikes need to be kept on charge when not in use. It would be good if the GPS and GSM circuits powered down until movement was detected thus only requiring a few mA when in standby, but I do no if there is a command for this. Can you share the link for creating you own server? Great job. Thanks for sharing.

[@christiannielsen3863]

Yeah their documentation on this product is very very poor. Even today a year later. You are able to make the GPS tracker to go to sleep if you send "sleep123456 shock". Then it will only draw very few mA until the device is shaken.

Impressive module for the price and its size! I'd definitely be interested to see the OSS server in a future video.

I will probably do it but I don't think I'm gonna succeed in configuring this tracker to connect so maybe it's best to wait and get another tracker so I can have a fully working system.

[@ristomatti]

@@voltlog It might be simpler to just build your own? Even though it'd end up being more expensive and less stealthy... At least you seem familiar enough with car electronics to be able to hook it up somewhere it'd not be easily spotted.

[@alessiozanutta2698]

I want to explain cj730 yuntrack app Comandos please I want to know the job of all commands

[@sordello51]

How do you mount it to receive the GPS satellite. It can't possibly be mounted under the hood. No clear signal at all! The last few years I've mounted them under the dash on the right side usually using a puck style antenna. This design would not fit.

[@voltlog]

under the dash would work nicely, also in the back near the back window would also work.

[@TheDefpom]

I had a gps tracker about 5 years ago, command and control system looked the same, unit itself was very different though. I remember a similar issue with the server connection, it was something to do with the command being sent, I just don’t remember what it was.

[@voltlog]

yeah, I'm not sure I'll ever figure this out because even if I setup my own server the tracker is still going to be pointing at the wrong address the way I see things..

Set your own external IP-Address and check the Firewall on wich port the tracker tries to connect. Then set a forwarding for these port/ports to your own internal Server and analyse the traffic with wireshark. I think this tracker posts it's position via http. No encryption or other complicated stuff. It seems to be port 7700.

[@voltlog]

The problem is, I'm not seeing any connection, the trackers is not contacting the server.

[@jangrewe]

You can configure the port you want it to send to. For Traccar, 5013/tcp is the port of choice. And no, it's not using HTTP.
