Both RTC and GSM works independently.
But GSM is not working, means messages are not received by the controller. I tried to use interrupt but, not enough space. |

Sorry. I forget to give the details. The circuit is nothing but a 3-0-3 centre tapped transformer- a rectifier to make it and a 10uF capacitor for smoothening and reading using ADC of PIC16f877a.
