adminip123456 'server ip + space + port'
Hello how are you? I have a question, after sending the command adminip123456 'server ip + space + port' with which number of identifier I add my (CJ720) in the server. From already thank you very much.
Hi.
The 10 digit device ID should be on barcode on the plastic cover of the tracker.
Also remember to send admin user cellphone number to unit first.
Thank you! At the end, I went to the station by placing the cell phone number on the server, I tried the ID and it did not work. Thank you.
Yesterday I asked you how to do the registration of my device and I told you that it had gone well which was a mistake, it was another device that was connected. I mean I still have the same problem. I already send the command adminip123456 xxxxxxxxx.ddns.net 5055 and I'm going every 5 minutes to the LOG of the server and nothing. Now redirect the port on the router and disable the firewall just in case. The sim has internet balance so everything should work. The device is a CJ720. I try to install the client on my cell phone and it is reported correctly. It occurs to you that it may be happening?
From already thank you very much.
I found a possible problem, send the command adminip123456 xxxxxxxxx.ddns.net 5055 but instead of sending the address I put the public ip of the server adminip123456 190.133.15.xx 5055 and started to report in the server log. Now I know that maybe it only accepts IP and does not accept domain names. Now I decoded the code and it gave me * HQ, 7401000xxx, V1,195921, A, 3441.1490, S, 05614.2700, W, 000.00,000,290519, FFFFF9FF, 748,01,0,0,6 #
According to Jostein Hove-Henriksen of using h02 what is not is where to enter that information. Could you help me? Thank you
The only place you need to set port is when you send adminip command to tracking unit which in your case should be:
adminip123456 190.133.15.xx 5013
Also then ensure this port is open on your server firewall
Hello, if you are using a DNS server you have to enter the following command:
SZCS,123456,DOMAIN=www.myurl.dyndns.org:5013
To my knowledge it works only with 2G SIM cards. In India these days you may not get 2G SIM cards. You will only get 3G SIM cards. And some GSM providers like Jio uses only 4G LTE service. So Indians please be careful.
Does anyone know how to disable SMS reports on this device?
Thanks to the earlier comments, I have it connected to my Traccar server as protocol h02, on port 5013, but it seems to insist on sending SMS reports as well, which are much, much more expensive...
Thanks.
ps. Fairly nice teardown and command set here:

It seems that this device is the same as Micodus MV 720 there is an official pdf with all commands on micodus.com
