I am interfacing GSM modem with ATmega16…
I am able to send the SMS from the GSM modem SIM300 when interfaced microcontroller ATmega16…
But I am not able to receive the SMS…i mean SMS is getting received but I am not able to program my controller to decode the received SMS…
Please help me out for understanding the logic or the steps to be followed to receive the sms from the gsm modem when interfaced to Atmega16…GSM works based on AT command
1st u download the at commands and use it..
most of GSM works based on UART communication…..
so u connect ur gsm to ur controller thriugh rs232 and MAX232…….
when u get sms to ur GSm it gives the command as AT++CMTI: “SM”,1
thriugh this command u can decode ur message…
and one more imp thing is if ur sim message is full it will not show ur message……
first u delt ur sim message and try this……………………………
hope u undrstnd
