GSM SIM 300 with PIC 16F877A GSM response data display on LCD problem

[Dhananjaya]

 

 

Sir

I have tested for the following code but it will display only for Carrage return(CR) and Line feed (LF)values  i have checked the ASCII table. GSM SIM response data add with 0x30 so it will display like =: so it will in the ASCII table check thisless than this  values  – 0x30 it will for CR and LF but not display like OK

please help me… what are the instructions to do this getting like OK . I think it will not given OK from GSM SIM response please check my code and correct it …

  wait(50);

} while(1);

}

Hi,

Could you please make your query more clear ?

[manimaran]

You have to wait untill a 0x0d or to receive after that u can display the data..

 

I dont know why are u saying about 0x30..
