Hi guys,
i'm trying to learn gsm modem communicatin with microcontroller(pic16f877). in 'C' laguage.
I'm able to send sms but cannot receive any message. I'm trying to display 1st two characters of a SMS on location 1 using the code below.....but the code isn't working.(in hyperterminal the same command "AT+CMGR=1" shows the message)
Code:
printf("AT+CMGR=1");
putch(0x0D);
putch(0);
DelayMs(200);
sms[0]=getch();
sms[1]=getch();
lcd_clear();
lcd_goto(0x80);
lcd_puts(sms);
i'm using standard AT+CMGS command with printf for sending sms which is working properly. One thing more, i think there shouldn't be any problem with my hardware , cause when i do this communication between uC & Hyperterminal, Hyperterminal shows "AT+CMGR=1" and then if i press any 2 keys on keyboard the same are shown on LCD.
Please help me out.
With best regards,
Neelam
