Result and Analysis

The programming for the gsm and hardware not successful for interfacing. The data from hardware can be send to mobile phone, but from the mobile phone send the message to gsm for asking the parameter solar cannot be reply from hardware.

Conclusion:

As a conclusion, i think hardware cannot read for asking from the mobile phone or programming conflict for the programming send to mobile phone. i will find out what the problem in this case as soon as possible.
