[SOLVED] Problem with MikroC Pro when reading SMS using UART1_Read_Text

[KasunLK]

Hi

I am new to MikroC and I have a problem with UART1_Read_Text();
I use Real PIC Simulator 1.1, My Mobile connected to COM7

Please help me.

I can send SMS, No problem, it works fine.

but when i receive SMS,

(1) i can read it char by char using UART1_Read();
output[0] = UART1_Read();

(2) if I use variable 'i' for array index, then I get garbage values.
output = UART1_Read();


(3) if I use following(Pls See below ) code, it gives garbage again.
UART1_Read_Text(output, 0X0D+0X0A , 90);


In fact it is like this. It reads numbers well.
but when reading characters it missing first bits.

eg:- for "REC" which is "1010010(R) 1000101(E) 1000011(C)"
it gives "<DC2><ENQ><ETX>" which is "0010010(<DC2>) 0000101(<ENQ>) 0000011(<ETX>)"

ASCII-characters
ASCII character set

How do I solve this problem.


My code like this

uart1_init(9600);
delay_ms(100);

uart1_write_text("AT+CMGR=1");
delay_ms(1);

UART1_Write(0X0D);
Delay_ms(1);

UART1_Write(0X0A);
strcpy(output,"");
Delay_ms(10);


b:
if (UART1_Data_Ready())
{
UART1_Read_Text(output, 0X0D+0X0A , 90);

UART1_Write_Text(output);
}

goto b;

I think I found the reason.
it is array size.
it allows to create a char array of size 95
but it caused the problem with uart1_read_text()
I reduce the size to 80. then it work fine.
