Hi, i'm trying to send gprs commands to a meitrack mvt340 tracker.
I have the next issue, when i send ie (to set time interval): @@V27,861074027388027,A12,3003 the tracker not responding me.
But when i send @@V27,861074027388027,A12,6D6 the tracker response $$V28,861074027388027,A12,OK*03 and write this settings.
I've checked that the problem is de number of digits in the time value.
When time < 10 it works everytime. When time >= 10 doesn't work.
I've checked the checksum and that seems to be ok.
The same problem occurs when iḿ trying to set speed limit alarm.
Have anybody some idea?
Well, I think there is a problem with message format. Length of the message seems to be incorrect.
Thanks! It was the problem.
Hi Argm.uy.... how to fix?
