hello i am a student and i am trying to make a project with avr (mega8515) and gsm modem.
i use codevision and enable the usart transmiter. also i connect RS232 spare with portd in pins 0 and 1. then i write this code
#define CR 0x0D
.
.
main()
..
while(1) {
printf("AT+CMGD=6");
putchar(CR);
break;
}
this command must delete the message in index 6 but doesn't work why???
