LK900A device not responding to sms commands
Hi Thomas,
Actually bought this tracker and it arrived last week. Had the same issue as well. Was using an international SIM, which was roaming. I switch to a local sim and the device got responsive again. It can stop responding if the admin number was put in wrongly. Hence is why I don't use that function. What you can try is to reset is with begin123456, where 123456 is your password.
To change the server IP you need to use this command:
szcs,123456,domain=YOUR IP/DNS:PORT
Example:
szcs,123456,domain=google.com:443
The tracker will reply with:
SET IP OK! IP:google.com#443#
Hope this helps!
Hi,
I bought a LK900A device from Aliexpress to use it in my own traccar server.
I tried to set it up by sms, but only after the first message (admin123456 phonenumber) I sent I got a sms response (admin ok).
On all other commands there was no reply.
The device is functional. I can see the location and get alarms on lkgps.net and it reacts on sending a reboot command (rst) by sms.
I even tried using a different sim card, but the situation is the same.
I don't want to try to change IP settings for my own server when not getting any reply from device.
Has anybody faced such a problem or is there a solution to this problem?
