we are trying to make the transmission and reception continuously, i mean to say making it dynamic...
i.e.,
first we will be sending one command from microcontroller to the modem.let it be "AT+CMGR=1", then modem has to respond to the controller's command and sends message in the first location of SIM to the controller and corresponding action(LEDs ON).
after this action, it has to continue its next step like we send another command like AT+CMGD=1 so that first message will be deleted,corresponding response is accepted and again it has to send another command AT+CMGR=1(mean while after deleting first message we will be sending message to the SIM from another mobile), now also it has to read message and do corresponding action(if it is for putting off LEDs, it has to put off leds which we are ON till now because of the previous message) and this entire action is to be done repeatedly.......
but the thing happening actually here is board is automatically getting reset after every one action(it is calling main function inspite we are not calling at any part of program)
