where should i specify the mobile number in the below code using sim 800GSM with ATmega32A mic??

/* gsm.c: interface program for GSM modem */
#include "gsm.h"

//GSM AT COMMANDS

const char ATCommand[]   = "AT\r";

static void GSMrxack (void);

void GSMsndmsg(const char *PhNum, const char *GSMMsg)
{
 lcdclrr(1);
 
 lcdws("Sending SMS:");
 if(GSMsndphnum(PhNum)) {
  puts(MSG_START);
  puts(GSMMsg);
  puts(MSG_END);
  putchar(0x1A);
  GSMrxack();
 } else GSMerr();

 GSMRxResp();
 dlyms(1000);
 lcdclrr(1);
}
int8u GSMinit(void)
{
 lcdclrr(1);
 lcdws("GSM: ");
 if(GSMRxResp() && GSMmsgparam() ) {
  lcdws("OK");
  dlyms(1000);
  return 1;
 } else {
  GSMerr();
  return 0;
  }
}
static void GSMerr(void){
 lcdws("FAILED !");
}
static int8u GSMRxResp(void)
{
 puts(ATCommand);
 while(getchar() != 'K');
 return 1;
}
static int8u GSMmsgparam(void)
{
 puts(SMSCode);
  while(getchar() != 'K');
 puts(SMSSettings);
  while(getchar() != 'K');
 return 1;
}
static int8u GSMsndphnum(const char *PhNum)
{
 puts(SMSNumber);
 puts(PhNum);
 puts("\"\r");
 while (getchar() != '>');
 return 1;
}
static void GSMrxack(void)
{
 int8u x;
 do {
   x = getchar();
  }while(x != 'K' && x != 'E');
  if(x == 'E') if(! GSMRxResp() ) GSMerr();
}
int8u gsm_call_gen(const char *PhNum)
{
 puts(ATCall);
 puts(PhNum);
 puts(";\r");
 return 1;
}
void GSMRxCall(void)
{
 puts(ATRxCall);
}
void GSMDisCall(void)
{
 puts(ATDisCall);
}

So this the GSM code.

Aim of this program to send a message to particular person using gsm, gps , mic.

My question is if we want to send message means where should I specify the phone number in the above program.

Hi,

This is the support portal for Nordic Semiconductor products, so, unfortunately, we don't have any expertise on the modem you are using or the ATmega microcontrollers. You should probably try to ask in a more general forum or a forum related to the modem manufacturer.

Best regards,
