Sending and receiving sms using AT commands in embedded c

[sambavadekar]

I am doing a project to send and receive sms from a gsm modem using AT commands in embedded c. It also does controlling of the central locking system of the car based on the sms sent to it, like "lock" and "unlock", and sends back sms acknowledgment after doing the same. I am using 8051 to build this, it also uses relay to control the 12v lock of the car.

My problem here is, I am not able to do it successfully. Can anyone help me with the basic codes to do the same.

 

[fouwad]

write a uart_tx(char x) function and then

call in main function
uart_tx('A')
uart_tx('T')
uart_tx('\r')
so on
done it on atmega32 not on 8051 but its almost the same

It's really unclear about the entire code what you are using. Can you post the code here so that we can look in to it and help.

Thanks.
