Hi everyone ,
I made a gps tracker system for my car..
It always works but sometimes.. it cannot read the serial data, I cannot specify the problem because it appears after 2-3 days.. It appears then after 2-3 hours. it does what it should have do.. I couldn't understand....
Sometimes....
I call it ... nothing is done (normally it should turns the recieved call to busy then it sends the coordinates in a SMS message)
after 2-3 hours..
it sends the SMS ...
??????? 
??????
Do I have a mistake in code???
Thanks ...
