hi all
i want to write a micro C program from pic 18f452 to mobile phone using AT Commands to send a SMS. any body can explain this one with circuit diagram, it will be great help for me.
thanks.[/b]
 

To send AT commands to mobile phone, you supposed to use a Mobile with Serial port(RS232)... MikroC comes with a library for UART... you can find Circuit diagram to convert UART level to RS232 level in MikroC help file. Just send those AT commands calling Library functions..
