NEED HELP! Sending sms using gm862 and pic16f887 with mikroc

[Computer engineer]

Hello,
I am new to mikroc and i have a project to detect intrusion and fire and send alarm through gsm to any number i did that but for temperature sensor if it is higher than a 28 for example it sends an alarm message but whenever it is at this temperature or above it keeps sending the message forever many times i need it to detect high temperature and send the message once but it keeps sending !!!

 

[js]

Please for more info!
Where is your code? How we can help you without it?

P.s.
Telit gm862 modem have integrated python and you can program this job without PIC

i am using a temperature sensor that use one wire communication so i need to connect it to a microcontroller and the temperature sensor read temperature in a do loop and inside i have an if statement to check if temperature is greater than 28 it sends a message using the gsm to the user but as temperature is on the range of the if statement it keeps sending and i need it to check temperature and send the message once and if it check again and temperature is still on that range i dont want to send again , i try to break the loop but it doesnt work >>> am not allowed to put the code in the internet

i use this code from mikroe website for reading temperature

else
text[0] = '0';

text[2] = temp_whole%10 + 48; // Extract ones digit

// extract temp_fraction and convert it to unsigned int
temp_fraction = temp2write << (4-RES_SHIFT);
temp_fraction &= 0x000F;
temp_fraction *= 625;

// convert temp_fraction to characters

text[6] = (temp_fraction/10)%10 + 48; // Extract tens digit

// Display temperature on LCD

}

void main() {

Lcd_Init(); // Initialize LCD

Lcd_Cmd(_LCD_CURSOR_OFF); // Turn the cursor off
Lcd_Out(1, 1, " Temperature: ");

// Print degree character, 'C' for Centigrades
Lcd_Chr(2,13,223); // different LCD displays have different char code for degree
// if you see greek alpha letter try typing 178 instead of 223

Lcd_Chr(2,14,'C');

//--- main loop
do {
//--- perform temperature reading
Ow_Reset(&PORTE, 2); // Onewire reset signal
Ow_Write(&PORTE, 2, 0xCC); // Issue command SKIP_ROM
Ow_Write(&PORTE, 2, 0x44); // Issue command CONVERT_T
Delay_us(120);
Ow_Reset(&PORTE, 2);
Ow_Write(&PORTE, 2, 0xCC); // Issue command SKIP_ROM
Ow_Write(&PORTE, 2, 0xBE); // Issue command READ_SCRATCHPAD
temp = Ow_Read(&PORTE, 2);
temp = (Ow_Read(&PORTE, 2) << 8) + temp;

//--- Format and display result on Lcd
Display_Temperature(temp);
Delay_ms(500);
} while (1);
}

i just add after display_temperature an if statement if temperature is greater than 28 the i add at commands to send the sms
