HELLO everyone,
i started a project quite recently were i intend to combine the arduino uno and the sim808 module which has gps/gsm/gprs all together in one.
using just the gps functionality works fine, just the gsm both recieving and sending messages also works good. but combining them for what i intend makes the entire system falls apart.
i intend to be able to have some coordinates registered lets say position A position B and position c, and the system i intend to design is put on a moving, lets say car, now anyone on either of the positions will send a message with the alphabet denoting the position to a number lets say "A TO +23*******98 , AND WOULD get a reply of the cars current time from that position.
with all parts combined the program would sometimes not even indicate recieving any message or evn if it did the gps part wont even work.
is there something i am doing wrong or is it not just feasible with what the components i am using
pls help as i very confused right now. thanks in advance
