Please check the code
| Code: |
#include <16F877A.h>
#include <string.h>
#FUSES NOWDT //No Watch Dog Timer
#FUSES XT //Crystal osc <= 4mhz
#use delay(clock=4000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,BRGH1OK,ENABLE=pin_c0,RESTART_WDT)
#byte trisc= 0x87
char rxd[20],rx;
void sms_hi_temp(void);
char phonelist[3][13]={ "+94XXXXXXXX",
"+94XXXXXXXX",
"+94XXXXXXXX"};
void initz(){
set_tris_b(0xFF);
bit_clear(trisc,0);
bit_clear(trisc,1);
setup_psp(PSP_DISABLED);
enable_interrupts(GLOBAL);
}
void init_gsm(){
printf("AT+CMGF=1\r");
delay_ms(1000);
printf("AT+CMEE=1\r");
delay_ms(1000);
printf("AT+CPMS=");
putc('"');
printf("SM");
putc('"');
putc(',');
putc('"');
printf("SM");
putc('"');
putc(',');
putc('"');
printf("SM");
putc('"');
printf("\r");
delay_ms(1000);
}
void main(){
initz();
output_high(pin_c1);
output_high(pin_c2);
delay_ms(1000);
output_low(pin_c1);
output_low(pin_c2);
init_gsm();
sms_hi_temp();
while(true){
}
}
#int_RDA
void RDA_isr(void)
{
gets(rxd);
}
/////////////////////////////////////////////////////////////
void sms_hi_temp(){
int l=0,i;
printf("AT+CMGS=");
// putc('"');
for(i=0;i<13;i++){
putc(phonelist[l][i]);
}
// putc('"');
putc(13);
delay_ms(2000);
printf("High TEMP");
putc(26); //send the msg
}

above is my gsm command program to send message to my phone. but nothing happened. so i tap the gsm moedm's TX pin to Hyper terminal and this is what it prints
AT+CMGF=1
OK
AT+CMEE=1
OK
AT+CPMS="SM","SM","SM"
+CPMS: 2,28,2,28,2,28
OK
AT+CMGS=+94XXXXXXXX
> High TEMP
+CMGS: 133
OK
but message never receive to my phone.
when i send "AT+CMGS=+94XXXXXXXX"(with the " ") instead of AT+CMGS=+94XXXXXXXX it returns CMS ERROR: 305 (Invalid Text mode parameter)
i connected to GSM module to hyper terminal and type the number (with and without " ") and it works both way.
can any one tell me what's going on? |

delay_ms(10);
printf("AT+CMGS=\"+94XXXXXXXXXX\"\r\n");
delay_ms(10);
printf("HIGH TEMP\r\n%c",26);
