hello...
could anyone please tell me how exactly to send at commands from 8051 to a sim300 gsm module?? Particularly using printf statements:!: i have tried sending it through strings and been successful to receive it at the serial window. But i saw a sample program on net which uses simple printf statements to send these AT commands. i tried replicating that program but in vain. So please somebody let me know how to do it
thanks in advance
