Thanks guys , WOW lot of good advices , yes I checked the messages there was value 0 , it took 2 days for the customer to send the vehicle to us , once we checked , found out there was a problem with a wire ,which had happen during vehicle's maintenance work. We have fixed it and will test for next 5 days then update with the outcome.
For this vehicle we use Atrack Ak1 , and we have set the tracker to report to server every 5 seconds , I can imagine your expression , but this customer wants the vehicles travelled milage and exact track.
We have around 50 analog FLS , most of them with Atrack and some with Teltonika and Queclink , Wolf if you need to see how they work , I can allow you access.
Feel like we are one good team
Again , Thanks a million guys ,
