}
}
when i use the scanf command i get the same information that i send (the AT
command) if use the GetData() the program crash out. why??? what must i
change to read a message from gsm???
(the connection between gsm and stk is why null modem cable (2 females) and
i connect the 2,3,5 pins from cable to 3,2,5 on avr the same connection is
on modem)
please help me because time pressure me and i don't know what to do...
i hope to your answer...
